Waterproofing - F.A.Q
Is waterproofing included with perimeter drain replacement?
Yes. We install waterproofing membrane and dimple board as part of a complete exterior drainage system.
What is the difference between damp-proofing and waterproofing?
Damp-proofing resists soil moisture, while waterproofing provides stronger protection against water intrusion and hydrostatic pressure.
Do you excavate the full foundation wall?
In most cases, excavation is required to properly apply exterior waterproofing.
Will landscaping be restored after excavation?
Yes. We complete professional backfill and site restoration after installation.
