Cost Of Underpinning Foundations

The cost of underpinning foundations can vary greatly depending on the location and severity of damage. This is because every situation is different and requires an individual assessment by an expert.

The costs of underpinning are based on the method that is chosen, as well as other factors such as materials and equipment used. It is best to consult with a Structural Consultant who will help you decide what the best method of underpinning is for your particular property.

Conventional Mass Concrete Underpinning

This is the most traditional method of underpinning, where soil is replaced by concrete. This method is a great way of underpinning shallow foundations, as it does not require large equipment or excavation.

Resin Injection

A resin injection is a more modern underpinning method that involves injecting a special compound into the soil to improve its properties. This can prevent the onset of subsidence problems by absorbing excess water and binding the soil to the existing foundations.

Screw Piers and Brackets

This is another underpinning technique that uses screw piles to reinforce your foundations. It is usually used in cases where the conventional underpinning process is not feasible. This can be due to the building requiring excavating to a very deep depth, or there is no way of using piling rigs.

There are three primary underpinning methods – conventional mass concrete, screw piers or push pier and chemical underpinning. These methods all bear different costs.

The cost of underpinning is typically between $15,000 and $50,000. This is based on the size of your home and how many piers need to be installed.

As with all construction projects, the type of material and equipment used will affect the cost of underpinning. This is especially true for resin injections and screw piers, which are more expensive than the other two methods.

In some cases, it can be more economical to build a new foundation than repair an existing one. This is especially the case when the structure has changed in some way, or you need to add a load to it.

Other times, it is more economical to carry out the work to make your existing foundation stronger, if you have the budget for it. This is often the case if the original foundation has become weak over time, or if the house was built on a foundation that was not adequate for the soil conditions.

Subsidence is another reason to have your foundation inspected and repaired by a professional. This can be a costly and lengthy project, but if the problem is causing structural damage to your home, it is worth spending the extra money to have it corrected before more extensive and expensive work is needed in the future.

The most effective underpinning solution is to have a structural engineer visit your home and take a close look at the situation. This will enable them to recommend an appropriate underpinning technique and give you the peace of mind that the solution is correct for your property.
