Etobicoke & Greater Toronto Area
We provide exterior foundation waterproofing for homes in Etobicoke, Toronto, and Mississauga. The work involves excavating around the foundation, applying a waterproof membrane to the wall, installing drainage board and weeping tile, and backfilling properly so water moves away from the structure.
Exterior foundation waterproofing is one of the most thorough approaches to addressing water intrusion in a basement. Instead of managing water after it gets inside, the work happens on the outside of the foundation wall — blocking the path water takes before it reaches the interior.
The process starts with excavating around the perimeter of the foundation down to the footing. Once the wall is exposed, it's cleaned and inspected, a waterproof membrane is applied, drainage board is installed against the membrane, and weeping tile is placed at the footing to carry water away from the base of the wall.
This type of work is commonly done on older homes in Etobicoke and Toronto where original waterproofing materials have deteriorated over decades, or where weeping tile systems were never properly installed in the first place.
These are common indicators that water is getting into or near your foundation. They don't all require the same fix, but they're worth looking into before the problem gets worse.
Streaks, wet patches, or staining on concrete or block walls — especially after heavy rain — usually indicate water is moving through the wall from outside.
Efflorescence — the white, powdery residue you sometimes see on concrete — is left behind when water passes through the wall and evaporates. It's a sign moisture has been moving through the foundation.
Vertical cracks can let water in. Horizontal cracks are more serious and may point to soil pressure. Either way, an in-person look is the right next step before deciding on a course of action.
A persistent musty odour is often caused by elevated humidity from moisture seeping in through walls or the floor. Mould growth in corners or along walls is another indicator.
If the ground around your home slopes toward the foundation, or downspouts discharge close to the wall, water can accumulate against the foundation and increase the pressure on it over time.
Paint peeling or bubbling on concrete is often caused by moisture pushing outward through the wall. It doesn't fix itself — the source of the moisture needs to be addressed from the outside.
Each job is different. Here's a breakdown of the specific work we carry out as part of an exterior waterproofing project.
The complete exterior waterproofing scope — excavation, wall preparation, membrane application, drainage board, weeping tile, and backfill. This addresses the outside of the foundation wall rather than managing water after it enters the basement.
We excavate the soil around the foundation perimeter down to the footing level to expose the full height of the wall. This is the necessary first step before any waterproofing work can be done on the exterior surface.
Once the foundation wall is cleaned and prepared, a waterproof membrane — typically a rubber-based or bituminous product — is applied to the exterior surface. This creates a barrier against water passing through the wall material.
A dimple mat or drainage board is placed against the membrane to create a gap between the foundation wall and the surrounding soil. This allows any water that reaches the wall to run down to the weeping tile at the footing rather than sitting against the membrane.
Weeping tile — a perforated drainage pipe — is installed at the base of the foundation to collect and redirect water away from the footing. On many older Etobicoke homes, the original clay weeping tile has collapsed or clogged and needs to be replaced entirely.
Beyond the membrane and drainage system, we look at site conditions that contribute to water entry — grading that directs water toward the house, downspouts discharging near the foundation, and areas where soil has settled against the wall. Improving these conditions is part of a complete approach.
A clear sequence from first call to finished job.
We visit the property, look at the basement from the inside, inspect grading and drainage conditions outside, and give you a clear written quote. There's no fee and no commitment required.
We excavate the soil around the affected section of foundation down to the footing. The excavated area is supported safely and the foundation wall is cleaned and inspected before work begins on it.
The waterproof membrane is applied to the cleaned wall surface. Drainage board is installed over it, and weeping tile is placed at the footing and connected to a proper outlet or sump system.
The excavated area is backfilled in layers, compacted, and graded to slope away from the foundation. The surface is restored as close to its original condition as practical and the site is cleared of materials.
Foundation waterproofing is site-specific. We come to you, look at the wall and drainage conditions in person, and quote based on what we actually see.
You receive a clear written quote outlining the agreed scope, materials and price before work begins. If unforeseen site conditions or requested changes affect the scope, we discuss them with you and receive approval before completing any additional work.
We carry general liability insurance. Proof is available on request before any work begins on your property.
We don't just apply membrane and cover it up. We look at the full drainage picture — weeping tile, grading, and discharge — and include what the job actually requires.
Call or text us and we'll respond as soon as possible with availability and the next steps for arranging an on-site quote. For something like water in the basement, a prompt response matters.
We work primarily in Etobicoke and the surrounding area. We know the soil conditions, the housing stock, and the drainage patterns in this part of the city.
We carry out foundation waterproofing work in Etobicoke and across the Greater Toronto Area. Here are the neighbourhoods and cities we regularly work in.
