Concrete Waterproofing Service in Wilmington, NC
Concrete waterproofing means applying a barrier system — either a penetrating treatment, a membrane, or a coating — that prevents water from passing through a concrete surface or joint. It's different from sealing; waterproofing addresses hydrostatic pressure and ongoing water intrusion, not just surface absorption. Concrete is porous and will absorb and transmit water given enough pressure or enough time. The right waterproofing system depends on where the water is coming from, not just where it shows up.

When to Call
When You Need Concrete Waterproofing Service
- Your below-grade garage wall is wet every time it rains more than an inch
- A planter box built against your Wrightsville Beach home is leaking through the concrete wall
- Water is coming up through the floor slab in your enclosed crawl space after storms
- You're enclosing a below-grade space and need to waterproof the walls before framing them
How It Works
Our Process for Concrete Waterproofing Service
- 1
Water Source Identification
We determine if water is coming through the wall face, up through the floor, or through a failed joint — each needs a different fix.
- 2
Surface Preparation
Waterproofing systems fail when applied over contaminated or unsound concrete, so prep is cleaned aggressively before any product goes down.
- 3
System Selection and Application
We match the product to the pressure level and substrate condition, applying in the required number of coats and covering all penetrations.
- 4
Joint and Penetration Detailing
Joints, cracks, and pipe penetrations get addressed separately because they're where most waterproofing failures start, not the flat wall face.
Wilmington Context
Why this matters in Wilmington
Wilmington sits close to sea level, and the water table in many neighborhoods is high enough to push up through slabs and through below-grade walls. After a named storm, that pressure increases fast and makes any gap in waterproofing obvious.
Straight Talk
About pricing & scope
The biggest variable is whether water is under positive or negative pressure against the surface. Negative-side treatments applied to an already-wet wall are limited in what they can achieve compared to addressing drainage outside the wall.
