Signs You May Need Waterproofing
Water always finds the path of least resistance. Identifying how moisture is entering your basement is the first step to a permanent solution.

Interior Waterproofing
A damp basement can be expensive, damaging and unhealthy! While exterior waterproofing is the best way to get to the source of the problem, interior waterproofing methods can seal out moisture when exterior access is not an option. If you are planning a new basement renovation, waterproofing is a must in order to protect your investment by preventing future water damage.
Weeping Tile | Sump Pumps | Backflow Valves
Weeping tile systems and sump pumps are parts of a drainage system designed to move excess groundwater away from your home. Older weeping tile systems should be examined for breakage or blockage and even replaced for maximum effectiveness. A mainline back-flow valve is highly recommended for new basement renovations as a preventative measure to keep your basement free of flooding and sewer back-ups.
Window Wells
Exterior Waterproofing
By far the most effective way to stop water from entering your basement is to install an exterior waterproofing system. A job best left to professionals, exterior waterproofing involves excavating around your house down to the footing, repairing and sealing the exposed foundation walls, and then installing a new weeping tile system to move excess water away from your foundation.
When to choose exterior waterproofing:
Exterior waterproofing gets to the source of the problem and is the best long-term solution for leaky basements. It's ideal when you want complete, permanent protection for your home.
