What Is Foundation Underpinning?

When it comes to building, it becomes a one-time investment, everyone wants the best. However, there are certain issues with buildings that are cropping up these days and one of the most problematic one being the stability of the foundation.

There are multiple issues which are a result of faulty and shaky foundations of buildings. This problem can be solved if detected as well. Professional help might be required if the problem persists or to prevent it from aggravating in the future. There are many different methods of stabilizing moving foundations and the best among them include the foundation Underpinning.

What is Underpinning?

Now, if you are not a professional you might not be aware of the term Foundation Underpinning. One might think that if a building is built with a faulty foundation that is the end to it and there can be no solutions to the problem. However, this problem can be solved very effectively which we might not be aware of. For centuries now, foundation underpinning has been used and it has given successful results.

So what is foundation underpinning? Foundation underpinning refers to a method of making the foundation strong even after the building has been built. It can be done by a number of methods which includes the concrete underpinning, resin injection underpinning and the like.

Each one of these underpinning methods has their own benefits and can be used in certain specific cases. Foundation underpinning basically refers to the method of making the soil under the base of your building strong and solid to make the building last longer.

Underpinning can be done using a number of materials, the most common among them is concrete. The concrete underpinning is done by digging deep holes in the foundation and filling them with concrete. When the concrete dries up, it expands and compresses the soil around it, in turn making the foundation solid.

Another method of underpinning is the resin injection underpinning which is a more modern method of underpinning and can be used effectively irrespective of the soil type and quality. In this a resin is injected in measured quantity into the soil to fill in the soil pores and when the resin expands it fills up those pores and the voids in the soil making the foundation strong again.

When Can Foundation Underpinning Help?

Now you might be wondering as to what all stuff can be taken care of by this kind of foundation underpinning? There are quite a number of things which occur as a result of foundation movement and all those can be taken care of possibly by foundation underpinning. Conditions in which a foundation underpinning helps include:

  • When there have been some constructions nearby and the soil beneath your foundation has moved
  • If you are planning to build some added walls or slabs in your room.
  • The soil condition has changed
  • The house has become too old and hence requires some base repair and obviously, you cannot pull the whole house down in order to make it stronger

Different Types of Underpinning

There are many different types of underpinning available these days some of which have been there since the last century and some are recently introduced. As already mentioned, two of the most commonly used Underpinning method includs the concrete underpinning – it is effective but cannot be used for large constructions and the resin injection underpinning – this is a more modernized version of underpinning these days.

The other methods of Underpinning might include the beam and base underpinning and the mini-piled underpinning. All these underpinning methods are designed and scientifically proved to hold on to buildings for longer than it was supposed to stand.

Underpinning is a concept which has been there for ages but it has become so popular these days because of the requirement. These scientifically proven foundation underpinning should be done under the supervision of professionals and practicing technicians along with the workmanship of skilled labour to get the maximum out of it.

The underpinning method can be chosen on the basis of the soil condition, the type of construction, the type of requirement for the construction as well as the budget. Do not let your house stand on moving grounds; make it stronger with foundation underpinning.
