Exterior Waterproofing

Exterior waterproofing is the most thorough way to keep water out of a basement, because it stops water before it ever reaches your foundation wall. It's the gold-standard fix — especially for chronic leaks and finished basements you want to protect for good.

Our crew excavates down to the footing, waterproofs the wall from the outside, and installs drainage that carries water away from your home. Then we put your yard back. It's a bigger job than interior work, and worth it when you want the most complete solution.

Our 8-Step Process

How exterior waterproofing is done

Every step done by our own crew — no subcontractors, no shortcuts.

01

Excavation to the footing

We carefully dig along the foundation to expose the full wall, all the way down to the footing.

02

Wall cleaning & preparation

The wall is cleaned of old coatings and debris so the new membrane bonds properly.

03

Crack repair & hydraulic cement patching

Any cracks or gaps in the wall are repaired and patched with hydraulic cement.

04

Liquid waterproof membrane

A thick elastomeric coating (or tar) is applied to seal the entire wall surface.

05

Dimple drainage board

A dimpled membrane creates an air gap and channels any water down and away.

06

Weeping tile installation

A perforated weeping tile pipe is laid at the footing to collect water and carry it off.

07

Washed gravel backfill

Clean washed gravel surrounds the weeping tile for fast, free drainage.

08

Soil backfill & grading

We backfill and grade the soil to slope water away from your foundation.

Lifetime

Backed by a lifetime transferable warranty

We don't just fix it — we stand behind it. If the problem ever returns, we come back and make it right at no cost, and the warranty transfers to the next owner.
