The Pros And Cons Of Using Polyurethane Foam Injections For Cracks In A Foundation

If you have cracks or chips in your foundation wall, you have to have foundation repair completed. If you fail to do so, a minor crack may continue growing until it becomes a major foundation problem. When it comes to foundation cracks, there are three main products that can be used to fill in the crack. This includes epoxy, polyurethane foam, and masonry compound. Each material has its own unique pros and cons associated with it. Here are a few of the pros and cons of using polyurethane foam injections to fill in foundation cracks. 

The Cons Of Using Polyurethane Foam Injections For Cracks In A Foundation

One of the downsides of polyurethane foam injections is that they simply fill in a crack to prevent moisture problems. They do not restore structural integrity to the foundation wall. If the cracks are minor, this is not a huge deal. However, if you have deep cracks that have weakened your concrete or masonry foundation wall, you may need to use a product, like epoxy, that fills in the crack while also strengthening the structural integrity of the foundation. 

The other disadvantage associated with using polyurethane foam injections for foundation cracks is that polyurethane is a pricy option. While there are many benefits associated with utilizing polyurethane foam, it is important to understand that the material is not cheap. If you are on a budget, this may not be the right repair material for you. 

The Pros of Using Polyurethane Foam Injections For Foundation Cracks

One of the biggest advantages associated with polyurethane foam injections for foundation repair is that this type of foam can be used on wet or damp foundation walls. Other repair materials cannot be used on damp walls. This means that your foundation may have to dry completely before a repair can be made. It can take days or even weeks for damp concrete or masonry to dry all the way out. With polyurethane foam injections, the repairs can be made immediately. 

The other benefit to polyurethane foam is that this foam expands as it is placed. This helps to ensure that the foam reaches into any cracks or gaps, filling them completely. With other materials, you have to spread the material into the crack. If the crack is not fully filled in, water can continue to penetrate through your foundation wall. 

If your foundation is starting to develop cracks, those cracks need to be filled. A foundation repair specialist can work with you to determine what material is best to fill in those cracks and gaps. In many cases, polyurethane foam injections can be a great way to fill in the gaps and protect your foundation wall.
