Frequently Asked Questions
Common questions about our basement waterproofing services.
What's the difference between positive and negative side waterproofing?
Positive-side waterproofing is applied to the exterior (water source side) of the structure, blocking water before it enters. Negative-side is applied internally and manages water that has penetrated the structure. Each has advantages depending on the situation.
Can you waterproof an existing basement without excavation?
Yes, negative-side waterproofing systems can be applied from inside the basement without external excavation. This is often the most practical solution for existing buildings.
Why is my basement wet even without visible cracks?
Concrete is naturally porous and can allow moisture to pass through even without visible defects. Hydrostatic pressure from groundwater can drive moisture through the concrete matrix.
Do I need drainage as well as waterproofing?
Often drainage systems complement waterproofing by relieving hydrostatic pressure. We assess each situation and recommend drainage where it will improve the overall solution.
