Water is one of the most damaging forces to your home’s concrete surfaces. When water seeps underneath your sidewalk or driveway, it can erode and wash away the supporting soil, causing concrete to sink and crack. Fortunately, there are effective methods to prevent water damage and protect your concrete.
1. Fill Voids with Polyurethane Foam
Polyurethane foam is a highly effective solution for supporting concrete and preventing water-related issues. At ’58 Foundations & Waterproofing, we use this expanding foam to raise and level sunken concrete and fill voids created by flowing water. Even if your concrete slabs appear intact, voids beneath the surface can compromise their stability over time. Injecting polyurethane foam into these voids ensures better support than soil, as the foam resists compression and won’t wash away.
2. Seal Cracks with Caulking
For a temporary and cost-effective solution, sealing cracks with caulk can prevent water from infiltrating your concrete. Flexible polymer caulks like Sikaflex 1a are excellent for sealing surface cracks or expansion joints. Caulking is a simple DIY option that helps protect your concrete from further damage. By sealing open cracks, you can block water entry and extend the lifespan of your concrete.
3. Build a Dirt Barrier
Creating a thick layer of dirt between your concrete and potential water sources is another method to prevent water intrusion. This DIY technique requires minimal skill and can be done using excess dirt from your property. While this method is inexpensive, it’s not as durable as polyurethane foam or caulking and may require frequent maintenance to remain effective. However, as a short-term measure, it can help keep water away from your concrete.
Take Action to Protect Your Concrete
Preventing water from seeping under your concrete is crucial to avoiding costly repairs. Whether you choose polyurethane foam, caulking, or a dirt barrier, taking proactive steps can save you time and money in the long run.
