Waterproofing & Foundations
Keep Your Home Strong, Dry, Healthy & Protected
Your foundation and waterproofing systems work together to protect everything above them. Cracks, movement, or water ingress can quickly lead to structural damage, mold, and costly repairs.
At Expos Construction, we provide integrated foundation repair and waterproofing solutions to keep your home stable, dry and safe for the long term.
Do You Need Foundation or Waterproofing Work?
You may need professional help if you notice:
- Cracks in interior or exterior walls
- Uneven or sinking floors
- Doors and windows sticking or not closing properly
- Damp or musty smells in the basement
- Pooled water, leaks or visible moisture on walls
- Peeling paint, efflorescence or mold growth
These are all warning signs that your foundation or waterproofing system is under stress.
Our Foundation & Waterproofing Services
We tackle the root cause, not just the surface symptoms—combining structural repair with moisture control.

💧 Interior Waterproofing
Protect finished and unfinished basements from the inside:
✔ Crack sealing (injections)
✔ Interior drainage channels
✔ Vapor barriers & wall liners
✔ Sump pump installation & maintenance
✔ Dehumidifier systems to control humidity
These systems help manage existing water and moisture, keeping interior spaces dry and usable.
🌧 Exterior Waterproofing & Drainage
Stop water before it reaches your basement or foundation:
✔ Foundation membrane installation
✔ Weeping tile & French drain systems
✔ Exterior excavation and wall sealing
✔ Grade correction around the home
✔ Foundation coating and protective barriers
By controlling water on the outside, we reduce hydrostatic pressure and protect the foundation itself.
Why Foundation & Waterproofing Work Matters
Getting both the structure and the moisture issues right offers powerful benefits:
✔ Prevents mold, rot & structural decay
✔ Protects basements, foundations & living areas
✔ Stops leaks and dampness permanently
✔ Improves indoor air quality and comfort
✔ Preserves property value and reduces future repair costs
