Waterproofing supplies

Have a leak in your concrete or block foundation wall of your house? This is a common problem for homes and it is one that needs to be fixed right away to avoid a wet basement. Water coming into your basement can lead to future problems, such as rot and mold. Many insurance companies do not cover a leaking foundation so it is important to fix the leaky basement right the first time. Completing a foundation crack repair can be a lot of work, but when done right, it could last a lifetime. Whether you hire a professional or do-it-yourself, Chapman's has all the products you need.
