How It Works

A complete, whole-basement approach to keeping water out of your living space, designed for Calgary's clay soils, spring melt and summer storms. Our team inspects your home first, then recommends only what your basement actually needs.

  • Full moisture assessment of walls, floor and grading
  • Interior perimeter drainage paired with a sump system
  • Wall vapour barriers and drainage matting where needed
  • Written warranty on installed waterproofing systems

Why Calgary basements need it

Expansive clay soil, fast chinook melts and intense summer storms put pressure on basement walls and floors. A managed drainage path relieves that pressure and keeps water off your floor.

Common Questions

How long does installation take?

Most residential projects take 1–3 days, depending on basement size and access.

Is it messy?

We protect your floors, contain dust and clean up daily.

Is there a warranty?

Yes. Our water management warranty: if water from the walls or floor/wall joint gets past the installed system onto the basement floor, we fix it at no extra charge for labour and materials. It covers the areas where the system is installed, lasts for the lifetime of the structure, and transfers to a new owner if we are notified within 30 days of the sale (a new-owner inspection and orientation is required). Warranties take effect once the work is complete and paid in full. It is not a guarantee of a dry basement and does not cover condensation, window well flooding, plumbing leaks, surface water flooding, wall dampness or efflorescence. See your written contract for full terms.
