Is this your problem?

Many GTA homes have a cold room under the front porch. The porch slab is its ceiling, so when the slab cracks or its waterproofing fails, water drips straight into the cold room.

  • Leaks or drips in the cold room ceiling or walls
  • Cracks in the porch slab or steps
  • Rust stains or exposed rebar in the cold room
  • A musty smell or mould in the cold room
How the job is done4 steps

  1. Open up the porch

    The surface is cleared and the sides of the porch are dug out.

  2. Repair the concrete

    Cracks and damaged areas in the slab are fixed.

  3. Membrane it

    Self-adhered waterproof membrane goes over the slab and down the sides.

  4. Restore the finish

    The porch surface, stone or pavers are put back.

QuestionsPorch & cold room waterproofing
What is a cold room?

An unheated storage room under the front porch, common in GTA homes. Its ceiling is the porch slab.

Can it be fixed from inside the cold room?

Inside sealers rarely last, because the water is coming through the slab from above. The lasting fix is waterproofing the porch itself.

Will my porch look different afterwards?

The membrane goes under the finish, so the porch can be finished to look the way it did. Discuss materials when you get your quote.
