Exterior waterproofing
Excavation down to the footing, foundation cleaning and repair, liquid-rubber membrane and a dimpled air-gap drainage board to keep water away from the wall.
Water in the basement
Basement Waterproofing
Interior and exterior waterproofing systems that stop leaks, seepage and dampness at the source and keep your basement dry year-round.
Know the problem
Do any of these sound familiar?
- Damp spots, staining or a musty smell in the basement
- Water pooling on the floor after heavy rain or snowmelt
- Efflorescence (white chalky residue) on the walls
- Peeling paint, bubbling or rot along the base of walls
What we do
Six ways we keep water out.
Interior de-watering systems
A drainage channel under the edge of the floor slab that carries water to a sump pit. The usual answer where digging outside isn't practical.
Sump pump installation
Reliable, correctly-sized sump pumps (with battery backup options) that move collected water safely away from your home.
Window well repair & drainage
New window wells, liners and drainage that stop water from pooling and spilling into below-grade windows.
Ecofloor subfloors
A dimpled subfloor membrane that creates an air gap and warm, dry, finished-ready basement floors.
Exterior & concrete crack repair
Targeted sealing of foundation cracks from the outside or by injection to stop active leaks.
What it costs
We quote it before we start.
It depends on the cause and the fix. One leaking crack is a very different job from full exterior waterproofing, so we start with a free assessment at your home and give you a fixed written quote before any work begins.
