An important construction method that can be used to intensify and stabilise the foundation of the existing building is termed underpinning. When an existing building faces issues like settling, subsidence, and structural inadequacy, this procedure is essential to safeguard the building or structure. Various methods can be employed to stabilise the foundation based on the conditions and requirements of a specific project. The ultimate goal of employing various methods is to bring structural  integrity and correct existing structural problems to provide long-lasting structures.

This article examines several underpinning techniques, their application, and their timing in strengthening different kinds of foundations.

What is Underpinning in Building Construction?

When unforeseen issues occur after construction is finished, the underpinning process is utilised to strengthen and repair the building’s foundation. Underpinning is required to promptly restore stability in the event that a footing or foundation breaks unexpectedly. To increase the overall safety of the structure, the process includes strengthening and deepening the current foundation with additional support.

What are the Common Methods of Underpinning?

When laying foundations, there are a few distinct methods that can be applied. However, the four methods listed below are the most popular ones:

Mass Concrete Underpinning

When extensive excavation is not necessary, this underpinning technique is employed. To strengthen the base, a concrete foundation is poured. This is a fairly simple foundation technique that doesn’t require large equipment. It is also a cost-effective approach.

Beam and Base Underpinning

This technique uses a conventional mass concrete base that is held up by beams to provide a sturdy foundation. In this type of underpinning, the beam that is built either above or below the concrete base will support the weight of the foundation.

Mini-Piled Underpinning

Mini-piled underpinning is a versatile technique that works well on a variety of soil types, including loose or soft ones, where conventional techniques are ineffective. It is perfect for crowded or built-up areas since it requires less excavation and causes less disturbance to the surrounding area. 

Jet Grouting

In order to build columns and other structures in the ground, the jet grouting technique entails cutting the soil with a high-velocity jet of fluid or fluids and combining the eroded soil with a self-hardening grout.

When is Underpinning Necessary?

When an issue arises in the foundation of the existing structure, there exists an underpinning procedure. The following are the common situations where underpinning is essential to perform.

Foundation Failure

When the foundation of the building or structure is not stable, reinforcements should be added to safeguard the existing structure without it falling or collapsing. It can also be possible when there is a poor foundation. The base soil should be strengthened to avoid uneven settlements.

Change in Building Usage

If there is any potential change in the use of the existing structures, you may choose this underpinning method. If you improve the strength of the foundation, then the load-bearing capacity of the building may increase tremendously and be apt for the intended use.

Soil Condition Changes

Different soils have different properties over time, such as deformable soils, decomposing soils, and so forth. The foundations may move as a direct result of this. In these situations, efforts are made to improve the soil conditions.

Adjacent Construction

The existing structure is significantly impacted by the excavation of adjacent structures. Therefore, if proper shoring is not implemented, it is essential to prevent or avoid the negative effects to ensure stability and prevent structural damage.

What are the Benefits of Underpinning?

The purpose of underpinning is to prevent the existing structure from falling or collapsing. Several benefits of underpinning are as follows:

Enhanced Structural Stability

Commonly, your existing building or structure is affected by a poor foundation due to various reasons like worsened weather conditions or just being worn out. To resolve this issue, underpinning is employed to strengthen your foundation and ensure that it is shielded from various disasters in the upcoming years. This results in providing safer shelter for the occupants.

Increased Property Value

The fact that underpinning raises the value of your property is among its biggest benefits. A well-built structure with completed underpinnings will be worth more when you decide to sell your property in the future, and you can expect a healthy return on your investment.

Accommodation of Additional Loads

If you want to change the potential load-bearing capacity of your property, you can use the underpinning method. It can increase the structural integrity of the building as well as its potential to bear greater traffic.

What Should You Consider Before Underpinning?

Only skilled professionals should manage the intricate process of underpinning. Hiring a qualified contractor with an emphasis on underpinning is advisable. Here are some important things to think about:

Cost: 

As underpinning can be costly, it’s frequently used as a last resort to repair damaged or weakened foundations. Costs can be significant because of the dangers. To make sure it works within your budget, always get an estimate before beginning.

Insurance: 

Before beginning any underpinning work, notify your insurance provider. Your policy will be modified to include coverage for the renovations. If you neglect this step, your insurance may be nullified, leaving you vulnerable in the event of an emergency.

Permit:

Make sure your contractor has the required permits for construction. Ignoring them at first could result in financial and legal problems, reduce the value of your home, and make insurance more difficult. Verify the competence of the contractor before starting the process. It is even better to check when you are searching for an underpinning expert.

Conclusion

A clever, economical, and less intrusive method of resolving issues of your existing building or structure and adding more space to your current structure is underpinning. Underpinning can help you save money and offers long-term advantages by strengthening your foundation. You can have peace of mind and a stronger, more resilient home or property by fortifying your building now to prevent future expensive repairs.

FAQs

For more than a century, wood has been used as a basic building material. Wood is still utilised extensively worldwide, despite new developments in construction brought about by materials like steel and concrete. As the wood industry has improved due to new technologies, this opinion is shifting, and wood is now appropriate for larger, more intricate buildings. More robust and taller buildings than ever before are being constructed with wood. 

It’s crucial for builders to understand the many kinds of wood, their uses, and their capabilities. Knowing how the major wood types are graded will help you choose the ideal one for your project once you have a solid understanding of them.

Types of Wood for Construction

Hardwood, softwood, and engineered wood are the three varieties of wood that are frequently discussed by builders. Only hardwood and softwood are solid, natural woods that are derived straight from trees. Conversely, engineered wood is a product of human creation. It creates a more robust and adaptable material by mixing wood products with other substances like resin or glue. Let’s examine these three categories of wood:

Hardwood

Angiosperm trees, which produce seeds with a protective covering, give rise to hardwoods. Pollen is transported from one tree to another by birds and insects that pollinate these trees. The plants provide seeds, nuts, or fruits after fertilisation.

Most hardwood trees shed their leaves every year because they are deciduous. The wood of these trees is denser and stronger than that of softwoods because they typically develop more slowly. Hardwoods are therefore ideal for building projects that must withstand weather or the elements. Hardwood is frequently utilised in strong decks, exquisite flooring, robust beams, sophisticated panelling, and long-lasting, fine furniture. These trees’ slow growth lends their wood a special durability and strength, making it a sturdy choice that lasts for many years.

Types of Hardwood 

5 common hardwood species used in construction are listed below:

Teakwood

With a light brown colour, teak is a popular hardwood that is excellent for indoor furniture and buildings, along with its robust, weather-resistant, and non-flammable properties.

Rosewood

Rosewood smells of flowers and has a lovely reddish-brown colour. It can be costly and is frequently utilised for high-end furniture and musical equipment.

Oakwood  

It resists moisture and fungi effectively and is utilised to make sturdy furniture like bookcases and cabinets.

Maplewood

Maplewood is ideal for high-traffic areas like floors because it is shock-resistant and light beige in colour. 

Ashwood

Ashwood has a lovely light brown colour and is durable and lightweight. It is more reasonably priced than oak and is frequently used for flooring, cabinets, and furniture. The timber industry frequently uses it.

Softwood

The gymnosperm family of trees, which produce cones rather than flowers or fruits, are the source of softwoods. These trees typically have straight, basic grain patterns, light-coloured wood, and rapid growth. Softwoods are incredibly adaptable and can be used for a wide range of products, including paper, furniture, building materials, and even energy.

Types of Softwood

Here are five popular types of softwood used in construction:

Pinewood 

Pinewood is light yellow and easy to stain. It is perfect for doors, windows, and floors but not suitable for outdoor use as it decays quickly.

Cedarwood 

With a stylish light brown, striped look, cedar wood is great for decorative furniture like chests and closets and naturally resists decay.

Firwood

A reddish-brown wood that’s harder to stain, ideal for furniture and interior structures.

Spruce Wood 

A strong and light beige spruce wood is used for high-end projects like ship masts and aircraft but needs upkeep to prevent decay.

Hemlock Wood 

A very affordable, lightweight, and versatile hemlock wood that is used for planks, doors, and joinery, though prone to decay.

Engineered Wood

Discarded wood pieces create more problems in constructing a structure. To balance this, engineered woods are created by using discarded pieces of wood. By adding some adhesives, these engineered woods are well known for their long-lasting property. For building a structure, engineered wood is a fantastic option due to its strength and budget. In large-scale construction, it can be used to create floors, walls, and beams. This lowers the wood waste and makes it more environmentally friendly.

Types of Engineered Wood

AC Plywood 

One side of AC plywood may be rough (C grade) and the other smooth and finished (A grade). When only one side is exposed, it works well for floors, fences, roofing, and furniture.

CDX Plywood

CDX plywood has an exterior glue that bonds the sheetboard together. One side of the plywood is C grade, and the other side of the board is D grade. It can withstand moisture and is apt for spaces like sheathing and subfloors.

High-Density Fiberboard (HDF) 

HDF plywood is made by compressing recycled wood fibers along with resins to become tough and versatile. It is ideal for making furniture, cabinets, and floors. To enhance its style and appearance, it can be painted or laminated.

Constructing a house or a commercial building with a unique design within a strict deadline is a challenge, and homeowners often have to sacrifice either time or design. However, spray-on concrete or shotcrete has been a revolutionary method, providing a balance between the two. 

They offer numerous benefits in the construction industry and have been used for a wide range of applications in residential and commercial buildings. This blog will explore spray-on concrete in detail and will help you gain a deeper understanding of how it is done.

What is Spray-on Concrete?

Spray-on concrete or shotcrete is a method of applying concrete to surfaces by spraying it through the nozzle under high pressure. This application can be used for a wide range of applications, including vertical, horizontal, and overhead structures directly without the need for formwork. The shotcrete used is of two types— dry-mix shotcrete and wet-mix shotcrete, and the application process and equipment differ based on the type.

Planning and Design

Accessing Project Requirements

It is necessary to identify the specific needs of the project, whether to construct structural reinforcement, decorative elements, or pool construction for other parts of the structure. After understanding the need, the type of concrete mix must be determined along with the necessary additives. 

Ensure that the design possesses the required load-bearing capacity, resistance to external conditions, and durability to withstand the elements for a long time. Set up an appropriate estimate and timeline based on the complexity and scope of the work.

Design Specifications

After understanding the requirements, create a design for the structure’s shape, determine the reinforcements, and specify the types of finishes to get a clear view of the structure that needs to be built with sprayed concrete.

Site Preparation

Surface Cleaning

Prepare the surface over which the structure needs to be installed. Ensure that the surface is free from dust, oil, grease, or contaminants on the existing concrete. Any cracks or voids formed on the surface need to be addressed, as they could affect the bonding.

Moistening the Surface

After cleaning, use light moisture on the surface to improve adhesion and prevent rapid evaporation caused by shotcrete, to ensure proper curing and water seepage.

Equipment Setup

Selection of Equipment

• The use of shotcrete machines varies based on the type of shotcrete materials used. Choose either a dry-mix or wet-mix shotcrete machine.
• Air compressors are essential for dry-mix shotcrete to propel the concrete into the nozzle.
• Pumps are used for wet-mix shotcrete to push the mixed concrete into the hose.
• Nozzles and hoses allow the control and flow of shotcrete in the spray pattern.

Safety Checks

Ensure that all the machines and equipment are in working condition to maintain an efficient flow, without causing any blockages or leakages.

Application Process

Nozzle Technique

Keep the nozzle at an appropriate angle between 30° and 90°, and spray at a distance of 45 cm to 90 cm for even distribution of shotcrete. The spraying process needs to be carried out back and forth, ensuring a uniform and consistent layer thickness.

Layering

If the surface is rough or porous, spray the first layer of shotcrete in a thin layer to create a tight bond with the substrate. After the initial layering, fill the subsequent layer with  a thickness of 1 to 2 inches, with frequent intervals, allowing time to set until it achieves the desired thickness.

Finishing

Surface Finishing

After the shotcrete is completely applied, finishing tools such as trowels, floats, or brushes can be used to achieve the required texture.

Curing

After application, keep the shotcrete structure moist for at least a week to allow the structure to attain the necessary strength and hydration. Periodic sprinkling of water can be done to keep the surface wet. 

In the case of rapid direct drying, avoid the exposure of structure to direct sunlight or hot external temperatures, as they could cause cracks in the surface.

Quality Control

Testing

The wet-mix shotcrete can be tested in the laboratory using a slump test to measure the workability. Compressive tests can be done to ensure the load-bearing capacity of the shotcrete after 7 and 28 days of curing. In the construction of tunnels and pools, the bond strength of the shotcrete to its substrate is tested.

Inspection

Visual inspection of the shotcrete surface can be done to ensure consistency in application, evenness in layering, and to check for cracks, defects, and honeycombing caused by poor compaction.

Safety Considerations

• It is mandatory to ensure that all the workers wear safety gear and are equipped with safety glasses, gloves, face shields, and hearing protection among other safety measures.
• In dry-mix shotcrete, there is a risk of dust pollution through the air; thus water sprays and proper ventilation methods can be used to suppress it.
• Site safety must be ensured by establishing emergency protocols in case of accidents and keeping the non-workers at a safe distance to prevent injuries.

Conclusion

In summary, spray-on concrete or shotcrete is an advanced and efficient method that is used in various construction applications. It offers a wide range of benefits in design flexibility and speed of construction. However, there are certain challenges when it comes to labour costs, equipment costs, and environmental concerns. But when carefully carried out, it can deliver superior results.

When you start your construction process, you may undergo several procedures and steps to ensure the structural stability of a building. Because the foundation is crucial when it comes to building construction, the foundation is referred to as the base, whereas the footing is its main component. Footing has its unique significance and characteristics when it comes to building a structure, ensuring its durability and longevity. 

In this Brick and Bolt blog, let us explore more details about the types of footings, applications, building processes, advantages, and disadvantages of footings.

What is a Footing?

Footing is an essential component of building construction, as it gives a building’s base structural stability and transfers the load from the structure to the ground. Each structure deserves a unique footing based on the location, soil conditions, and other environmental factors. Therefore, the stability of a structure can be greatly impacted by the types of footings utilised in building construction. To satisfy the requirements of various building projects, footings are often composed of concrete or masonry and come in a wide range of sizes and shapes.

Types of Footings

For effective transfer of loads from the structure to the ground, different footings are built for different construction projects. They are usually constructed depending on the building’s size, soil conditions, and load capacity. Here is a brief overview of the most typical footing types:

Strip Footing

This footing is long and narrow, and it extends the entire length of a wall. Usually shallow, it is effective for smaller load-bearing walls.

Spread Footing

Spread footing offers a reliable foundation for individual posts or columns. As they are stronger and wider than strip footings, they are perfect for supporting larger walls or columns to prevent settlement. They are built in various shapes such as round, square, and rectangular. 

Combined Footing

A combined footing is used when two or more columns are too near to one another for separate footings. A common broader foundation can be built to support multiple columns.

Isolated Footing

This foundation, which is often round or rectangular, supports a single column. Isolated footings are usually larger and deeper, made to support the weight of a single column.

Mat or Raft Footing

A mat footing is a sizable slab of concrete that covers the entire foundation area of the building. It is frequently utilised for large structures and disperses the load equally across the ground.

Pile Footing

Pile footings are used when the earth isn’t sturdy enough to hold up a structure. These are lengthy, deeply buried steel or concrete columns that offer additional support.

To ensure the foundation is secure and dependable, each type of footing is selected according to the building’s design, the state of the soil, and the structural requirements.

Application of Footing

Residential Buildings: 

Through supporting slabs, walls, and columns, footings give dwellings stability.

Commercial Structures: 

Used to distribute large loads and provide durability in offices, warehouses, and shopping centres.

Industrial plants: 

Footings are made to endure vibrations and support large machinery.

Bridges and flyovers: 

Footings are crucial for maintaining the stability of bridge piers and abutments during extreme weather conditions and loads.

High-Rise Structures: 

To withstand seismic and wind activity, deep foundations secure skyscrapers to stable soil layers.

Retaining walls: 

Footings keep walls stable so that soil pressure doesn’t cause them to collapse.

Water Tanks and Silos: 

Footings can distribute weight uniformly to ensure a safe installation.

Boundary Walls: 

They offer a sturdy foundation for durable walls and fences.

Sloped Terrains: 

In hilly regions, stepped footings provide level platforms.

Infrastructure Projects: 

Footing ensures the safe operation of roads, tunnels, and dams.

The Building Process of Footing

One of the first things that is done immediately after excavation is the construction of footings. The first step in the process is digging a hole for the footing. The size of the building and the type of soil determine how deep this hole should be. It must be deep enough to remain beneath the freeze line (where the ground freezes) and above any soft or loose soil.

When the hole is prepared, the footing is built by either pouring concrete into it or by utilising brick blocks, stone, or pre-made concrete. In order to adequately sustain the weight of the building, the footing needs to be level and extend past the hole’s sides. The foundation walls are built on top of the completed footing.  

Advantages of Footing

• Footings ensure stability by distributing a building’s weight uniformly across the ground, avoiding excessive stress on any one area.
• They can spread the weight on softer soils or reach deeper levels for strength, depending on the type of soil.
• Footings keep constructions from tilting, sinking, or breaking by preventing uneven settlement.
• Additionally, they stabilise buildings in the face of extreme weather by anchoring them against natural forces like wind, earthquakes, and floods.
• By raising the foundation above ground dampness, footings protect the building from mould and water damage.
• To guarantee correct alignment, they offer a sturdy, level foundation for walls, columns, and other components.
• Footings are modified to provide sturdy platforms on sloping terrains, enabling safe building even on uneven terrain.

Disadvantages of Footing

• Building a footing can be costly due to the substantial labour and material requirements.
• The entire construction schedule may be extended by the footing design and construction process.
• Unsatisfactory soil conditions may necessitate reinforced or deeper footings, which would raise the cost and complexity.
• Unfavourable weather conditions, including persistent rain or extremely cold temperatures, might make installing footings take longer than expected.
• Footings may need constant upkeep, particularly in locations with shaky soil or subpar design. 

What is the Difference Between a Footing & a Foundation?

S.No	Aspect	Footing	Foundation
1	Definition	The part of a building’s foundation that directly supports and distributes the weight.	The complete structural system that supports the building, including footings and foundation walls.
2	Purpose	Provides stability by distributing the load of the building.	Supports the entire structure, ensuring its stability.
3	Location	Located beneath the foundation, in direct contact with the soil.	Extends from the footings to the surface, including walls, slabs, etc.
4	Role in Settlement	Helps prevent differential settlement by spreading the load evenly across the soil.	Ensures the building is securely anchored to the ground.
5	Construction Requirement	Typically required by building codes to ensure stability.	Essential for supporting the entire structure, may or may not include footings.
6	Material	Usually made of concrete, stone, or brick.	Can be made of concrete, stone, brick, wood, or other materials depending on the type.
7	Risk of Failure	Improper footings can lead to foundation instability and cracks.	Weak foundations may lead to structural collapse or significant damage.
8	Maintenance	Regular inspection is needed to check for cracks or water accumulation.	Requires periodic checks for settlement, water damage, and structural integrity.

Factors to Consider in Footing Construction

The factors that need to be considered are as follows:

Soil Type: The size and depth of the footings depend on the kind of soil. While weaker soils could require larger or deeper footings to maintain stability, stronger soils can support greater weight.

Climate: To avoid settling or damage, footings may need to be deeper in places with a lot of rain or extremely cold weather.

Building Weight and Size: While smaller buildings could require less sturdy footings, larger and heavier structures require more.

Type of Building: Lighter constructions, such as residences, can employ shallow footings, but taller buildings need deeper, stronger ones.

Lateral Forces: To maintain the stability of the building, footings must be made to withstand forces such as wind and earthquakes.

Building Codes: To ensure safety and compliance, local building codes establish minimum requirements for footing design, including size, depth, and materials.

Conclusion

Footings are often overlooked, but they are vital for a building’s stability. They help transfer the weight of the building to the soil that can support it, ensuring the structure lasts.

Whether to employ piles, individual, combined, raft, or strip footings will depend on the style of structure and the condition of the land. The water table in the area, soil strength, frost line depth, and local building codes must all be taken into account while designing footings.
