Exterior Foundation Waterproofing: The Most Effective Long-Term Solution
Below-grade waterproofing applied to the outside of foundation walls. Excavation, membrane application, drainage board. Tampa, Orlando & Central Florida.
Why Exterior Waterproofing
Stops water before it reaches your foundation walls.
Exterior waterproofing is applied to the outside of foundation walls, below grade. Water hits the membrane first and is channeled away before it ever touches the wall. Interior solutions manage water that has already entered. For significant water intrusion or new construction, exterior is the most effective long-term solution.

Frequently Asked Questions
Why is exterior waterproofing the most effective?
Exterior waterproofing stops water before it reaches the foundation wall. The membrane is applied to the outside, so water never touches the wall. Interior solutions manage water that has already entered. Exterior is the gold standard for long-term protection.
What is the excavation process?
We excavate around the foundation to expose the walls. This allows us to clean, repair, and apply the waterproof membrane and drainage board. After installation, we backfill with proper drainage to direct water away.
What is drainage board?
Drainage board is a dimpled or textured material installed over the membrane. It creates a gap that channels water down to the footer drain. It protects the membrane and improves drainage.
