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.

🧱 Foundation Repair & Structural Services

  • Foundation Crack Repair
    Epoxy or polyurethane injections to seal cracks, prevent further movement and block water entry.
  • Underpinning & Stabilisation
    Solutions to support moving or sinking foundations and restore structural integrity.
  • Wall Reinforcement
    Strengthening bowed or leaning basement walls using engineered methods (e.g. steel or carbon systems).
  • Concrete Slab & Floor Levelling
    Addressing uneven slabs and supporting concrete where settlement has occurred.
  • Crawl Space & Basement Structural Corrections
    Repairing, reinforcing and protecting lower-level structures that support your home.

💧 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
