Underpinning Meaning

Understanding Underpinning: A Fundamental Aspect of Construction

Underpinning is a term frequently used in the construction industry, but it may be unfamiliar to many outside this realm. Simply put, underpinning refers to the process of strengthening the foundation of an existing building or structure. This is often necessary when the original foundation is not strong or stable enough to support the structure, perhaps due to changes in the soil supporting the foundation, or because additional floors have been added to the building.


Underpinning can be carried out using different methods, depending on the condition of the building and the nature of the ground beneath it. Some of these methods include mass concrete underpinning, beam and base underpinning, mini-piled underpinning, and jet grouting, among others. Each technique has its own merits and is chosen based on factors like soil type, depth of excavation, and load capacity of the structure.

Safety And Durability

In essence, underpinning is crucial for the safety and durability of buildings. Not only does it improve the structural integrity of the building, but it also enhances the building’s load-bearing capacity. It’s an indispensable process for buildings showing signs of subsidence, a common issue in construction where the ground beneath a building compresses or sinks, leading to misalignment or even structural damage.

Underpinning A House

Underpinning is a crucial technique used in construction to strengthen and stabilise the foundations of a building. Often required when the original foundation is no longer strong enough to support the structure, or when changes to the building or surrounding environment have caused instability, underpinning ensures the continued safety and longevity of your home. We will guide you through the process of underpinning a house.

Underpinning Foundations

Step 1: Assessing the Situation

The first step in the underpinning process is to hire a structural engineer to determine whether underpinning is necessary and, if so, what type of underpinning method should be used. The engineer will conduct an assessment of the house and its surrounding environment, checking for signs of structural damage and considering factors such as soil type and the weight of the building.

Step 2: Choosing the Right Method

There are several different methods of underpinning, and the choice depends on the specific circumstances of the building. Traditional underpinning, also known as pit underpinning, involves excavating sections of the earth beneath the foundation and filling them with concrete. Alternatively, beam and base underpinning involves constructing a concrete beam below or above the existing foundation, which transfers the load of the building to mass concrete bases at strategic locations.

Step 3: Undertaking the Work

Once the best method has been determined, the underpinning work can begin. This will be performed by a qualified contractor, who will ensure the work is carried out safely and to the required standard. During the underpinning process, it’s essential that the structural integrity of the building is maintained at all times.

Step 4: Final Inspection and Approval

After the underpinning work has been completed, a final inspection will be carried out by the structural engineer. If the work meets the necessary standards, the underpinning will be approved and your home’s foundation will be declared more robust and stable than ever.

Remember, underpinning is a complex process that should only be undertaken by professionals. However, understanding the process can help homeowners make informed decisions about the care and maintenance of their properties. With the right knowledge and expertise, underpinning can be a safe and effective way of improving the foundations of any house.

Underpinning Cost

Underpinning cost is a crucial consideration for any homeowner planning to reinforce the foundation of their property, and understanding the various factors that affect this cost can provide helpful insight into the overall pricing of an underpinning contract.


The first factor to bear in mind is the method of underpinning chosen. Traditional methods such as mass concrete underpinning are often less costly, but newer techniques such as resin injection or mini-piled underpinning may represent better value for some types of soil or building structures.

Size and Complexity

Secondly, the size and complexity of the job will significantly impact the cost. Larger, more complex projects typically demand more labour and materials, resulting in a higher overall price.


The location of the property is a non-negligible factor as well. If the site is hard to access or located in an area with high living costs, this can further inflate the price.

Risk Factor

In addition, one must account for potential risks and complexities related to the condition of the structure or the soil. Unforeseeable elements such as tree roots, water tables, or the need for temporary support structures can all contribute to an increase in the overall cost.

Insurance and Relocation

Lastly, indirect costs such as insurance, temporary relocation during the work, and potential increases in property values must also be factored in when pricing an underpinning contract.

Understanding the cost of underpinning is crucial for making an informed decision. By keeping these factors in mind, property owners can ensure that they receive a comprehensive and accurate estimate and that their investment in the stability and safety of their structure is a sound one.

The proper and timely execution of an underpinning project is essential for any structure, and understanding the complex price behind such projects helps to ensure that homeowners are getting the best value for their investment. With a deeper knowledge about underpinning cost, property owners can expect stability and peace of mind for years to come.

Underpinning Methods

When it comes to stabilising the foundation of a structure or property, underpinning is the go-to solution. There are several methods of underpinning, each suited to specific circumstances and soil conditions.

The Traditional or Mass Concrete Underpinning method, one of the oldest techniques, involves excavating sections of soil beneath the existing foundation and filling these with concrete. This process is repeated until a solid bed of concrete supports the property.

In contrast, the Mini-Piled Underpinning method is more suitable for sites with restricted access, variable soil conditions or where structural movements must be minimal. Mini-piles are drilled deep into the ground, transferring the load of the building to more stable subsoil.

Resin Injection Underpinning, a relatively modern method, introduces expanding polyurethane resin into the soil, effectively binding loose soil and increasing its load-bearing capacity. This method is often faster and less disruptive than others, but it requires careful control to ensure successful soil stabilisation.

Beam and Base Underpinning is another modern method, wherein a reinforced concrete beam is constructed above, below, or in replacement of the existing footing. The load of the structure is then transferred onto the beam, which rests on a mass concrete base constructed at a suitable depth.

Finally, the Pile and Beam Underpinning method involves driving piles on either side of the existing wall, then connecting these piles with a beam to support the wall, effectively redistributing the load.

Choosing the right underpinning method depends on various factors such as soil condition, property type, and budget. It’s crucial to consult with a structural engineer or a qualified underpinning contractor to determine the most suitable method for your specific needs. Remember, the goal of underpinning is to ensure the long-term stability and safety of your property.

Frequently Asked Questions About Underpinning

Does Underpinning Devalue A House?

Underpinning a house is a common renovation and repair option to fix structural issues. It can help increase the stability of foundations, support heavy loads such as patios, and in some cases raise a structure higher than its original grade. However, does underpinning devalue a house?

Underpinning alone does not devalue a house, but it may be seen as an added cost to the overall value of the property. Whether or not underpinning reduces the value of your home depends on how much money is spent on it and how long you plan to keep it. It’s important to consider all aspects when deciding whether or not underpinning will add more value than it subtracts.

For example, if you plan to keep the house for a couple of years and are only underpinning it to fix some structural issues then it could actually add value in the long run. However, if you’re planning on selling the house soon, it’s important to consider how much money will have to be spent on underpinning compared with other repairs that may have a more immediate effect on the market value of your home.

It’s also important to consider how much money you will need to spend in order for underpinning to add value, as costs can quickly add up if it has to be done right. According to the Building Research Establishment (BRE), underpinning is usually expensive and should only be considered when other repair options have been exhausted.

When considering underpinning your house, think about the long-term costs and benefits of doing so. Underpinning can add value to a property in the long run, but it should only be done after careful consideration and if it is necessary for stability or increased load bearing capacity. Ultimately, whether or not you decide to underpin your house will depend on the size of your budget and how much value it adds to your property.

In general, underpinning should be done with an expert’s advice; they can assess the scale of the job and give you a better understanding of potential costs and benefits. The experts can also suggest other repair options that may be more suitable for your circumstances. Ultimately, whether or not underpinning is right for you will depend on your needs, budget and the condition of your property. However, by doing some research into the pros and cons of underpinning prior to making a decision, you can ensure that it’s the best option for you in the long-term. 

How Long Does Underpinning A House Last?

Underpinning, a process aimed at strengthening the foundation of an existing building or structure, is a vital but often overlooked aspect of home maintenance. If carried out correctly by professionals, the effects of underpinning can last for several decades. Factors such as the material used, the condition of the soil, and the quality of the workmanship can influence the lifespan of the underpinning. It’s important to conduct regular checks and maintenance to keep the foundation in optimal condition.

Underpinning is especially crucial in areas prone to high levels of soil erosion or seismic activity. By reinforcing the foundation, you can protect your home from severe weather conditions and natural disasters. Additionally, underpinning your home can provide more stability for any additions or renovations you may want to make in the future.

It’s important to bear in mind that underpinning is not a one-size-fits-all solution. Depending on the structure of your home, you may need to consider different materials and techniques. Professional services such as structural engineers can provide advice on the best options for you based on your budget and needs.

When it comes to maintenance, regular inspections are essential for keeping your underpinning in top condition. This includes checking for signs of wear and tear such as cracks or crevices in the foundation, or any warping in the surface. Address any issues immediately to ensure your underpinning stays strong and secure for many years.

Although it’s a relatively costly process, underpinning is an investment that can save you time and money over the long run. With proper maintenance and care, it can protect your home and family from the elements for many decades to come.

As with any major renovation or repair works, it’s important to seek expert advice before you begin. Professional services such as structural engineers can help ensure that the process is carried out correctly and safely. With their help, you can rest assured that your foundation is in good hands. 


Does Buildings Insurance Cover Underpinning?

Buildings insurance typically covers structural damage and any necessary repair work, but it’s crucial to note that not all policies include underpinning. Underpinning is a specific, often costly, method of strengthening a building’s foundation and is usually required when substantial ground movement has caused structural damage. It is regarded as a last resort, applied only when simpler, less expensive methods are not suitable. Always check your specific policy details or consult with your insurance provider to determine if underpinning is covered.

In some cases, when the need for underpinning is identified during a survey to assess building damage, an insurance company may require that it be completed before they accept liability and provide payment. Whether or not this requirement applies depends on the terms of the policy and the specific circumstances of each case. Additionally, it may be possible to add underpinning cover as an additional clause to the policy.

The cost of underpinning is typically high due to the complex nature of the process, and it’s wise to understand what your insurance covers before taking on such an expense. Researching prices in advance can also help you plan for any potential out-of-pocket costs if your policy doesn’t cover underpinning. If you’re unsure about what is covered by your policy, contact your insurance provider for clarification.

Reinforcing the foundations of a building is an important step in preventing further damage or collapse, and understanding the coverage offered by your buildings insurance can help you make informed decisions about necessary repairs. With clear knowledge of your policy’s coverage, you’ll be better prepared to manage unexpected costs and keep your building safe in the long run. 

Is It OK To Buy A house That Has Been Underpinned?

Purchasing a house that has been underpinned may initially seem risky but it’s not necessarily a deal-breaker. Underpinning, if done correctly, can fortify the foundation of a house, improving its structural integrity. Prospective buyers should, however, ensure that underpinning was carried out by professionals and that the process solved the original problem. Requiring proof of all works, necessary permits, and final inspection sign-offs is essential. Additionally, consulting a structural engineer or a surveyor before purchasing can provide peace of mind.

Another important factor to consider is the cost of the property. If a house has been underpinned, this should be reflected in its price tag. Buyers can also ask for a discount if they discover that there are certain areas of the underpinning which haven’t been completed or need further attention. Ultimately, it pays to do your homework and ensure that you understand the risks and rewards of buying a house that has been underpinned.

If you do decide to buy, make sure that both your mortgage lender and the insurance company are aware of the underpinning. This is important in order to get an accurate valuation of the property. It’s also important to have a surveyor inspect any prospective properties before purchase, as this can help uncover any issues that may otherwise go unnoticed.

In short, buying a house that has been underpinned does not have to be a daunting prospect. With the right research and precautions in place, it can be a lucrative investment for those willing to take the plunge.

Finally, buyers should consider how long ago underpinning took place when making their decision – as with most things, the older the underpinning, the more likely it is to have been affected by wear and tear. Keeping an eye out for cracks or other signs of structural damage can help buyers be aware of any potential issues before committing to a purchase. With these tips in mind, prospective homeowners can move forward with confidence when considering the possibility of buying a house that has been underpinned.
