— What Is Basement Leak Repair?
It's More than a Patch — It's a Permanent Fix
We locate the true source of the leak and apply long-lasting repairs that actually work.
Basement leaks can come from cracks, gaps, poor drainage, or foundation failure. At DrySeal, we diagnose the issue using advanced tools and repair it with proven techniques — like crack injection, wall sealing, sump pump installs, or full drainage correction. We stop the leak at the root — not just the surface.

We Don’t Just Fix the Leak - We Stop It From Coming Back
Every repair starts with an expert diagnosis and ends with peace of mind.
Here’s how we permanently repair basement leaks
01
Inspection & Leak Source Detection
We find the origin of the leak using moisture mapping, thermal imaging, or camera scopes.
02
Crack Sealing & Injection
We inject polyurethane or epoxy into foundation cracks to form a watertight seal.
03
Interior Wall Sealing (if needed)
We apply waterproof coatings and vapor barriers to stop interior seepage.
04
Sump Pump Installation (if required)
If groundwater pressure is the cause, we install a sump system to relieve it.
05
Exterior Waterproofing (if applicable)
If the issue is external, we excavate, seal, and drain outside the foundation wall.
