Waterproofing Your Basement Walls

Basement walls suffer from leaks too often.  If you are a homeowner and haven’t had to deal with a leaking basement, consider yourself lucky.  Even in the best-built homes, cracks in foundation and basement walls will eventually form.

Cracks are formed from moisture in the soil outside basement walls.  Some homes are built over very damp soil or on flood plains, and they are almost guaranteed to suffer from leaks.  A sump pump may even be needed to constantly remove water from the basement.

Homes built on dry soil can also be vulnerable.  There will be times during heavy rains or spring thaw when there will be increased water deep in the ground.  That, in turn, will increase the chance of leaks through your basement walls.

As soon as water leaks into your basement, you have a problem.  Water can seriously damage your basement walls, foundation, and your belongings.  Water also attracts mold and mildew, which can cause breathing problems and create an unhealthy atmosphere for your family.
