3 Things to Know about Resin Injection House Underpinning

Posted on: 8 January 2018

There are several things that may be affecting the underpinning of your house. Your foundation may be suffering due to the soil, erosion from storms or issues with the house itself. If you are considering house underpinning, then resin injection may have been discussed as an option. Before you go with a resin injection method, there are a few things you should know and consider about the process.

Soil May Prevent Resin Injection

There are some cases where the soil may prevent the resin injection from working properly. This is especially true in areas that are near the beach or ocean where sand is looser. In some cases, the soil is weak due to construction nearby that has depleted soil integrity. If the soil is too weak, it will not hold up to the weight of the resin and will cause issues while the resin is settling. In severe cases, if the integrity of the soil is extremely poor, then the resin will fail and the foundation damage will increase.

Excavation Is Avoided

One of the steps in the underpinning process that people dread is the excavation portion. This is common with concrete underpinning. The cement of the foundation is generally broken up and broken down, which causes dust and other contaminants to enter your environment. In addition to the contaminants, you will also be facing the noise of the construction and underpinning. This is all avoided with resin injection methods. Also, the time taken for excavation and construction is cut down considerably since injection methods only take a day or two to complete.

Filling Unseen Gaps

One key point to keep in mind about resin injecting is how it works on the gaps and cracks you may not see. The injection method sends the resin into specified, small holes that are drilled into the foundation. The resin then expands, filling those holes and strengthening the underpinning. During the expansion, it also fills in holes and gaps or cracks that you may not see. This helps to reduce the chances of your foundation cracking and allowing water to enter into the gaps, which will further break down the foundation.

By keeping these key points in mind regarding resin injection, you can be better prepared for the process and what stumbling blocks you may encounter. Keep in mind that the first step to any house underpinning is to have an evaluation of the house and the land surrounding the house performed. Once this is completed, you can better decide how to proceed with your house underpinning needs.


How to Construct a House

Hello, my name is Lisa and this is my blog. I live in Perth, Australia and for the past two years, I have been working on my home to improve it. My husband works away a lot, so the upkeep of the family home is completely in my hands. At first, I didn't have a clue what I was doing. Thankfully, my brother works as a contractor and knows about electrical wiring, plumbing and general construction. He gave me some great advice so I decided to start this blog so I could pass on his wisdom to others. I hope you enjoy my blog.
