On a sloped Burnaby lot, water moves across the surface and through the soil faster than on flat ground and collects against the downhill foundation wall. From Capitol Hill to the properties stepping up toward Burnaby Mountain, the work here is about managing that slope — surface grading, intercept drains uphill of the house, and a perimeter drain that can handle the volume. We repair and replace perimeter drains and solve the yard drainage problems that come with hillside properties.
On a slope, surface water runs toward the downhill side of the house and can pool against the foundation wall if the grading does not direct it away. Subsurface water moves through the soil downhill and hits the foundation the same way. The fix is usually a combination of surface grading or a swale to direct surface water around the house, and a perimeter drain at the footing to relieve the subsurface pressure. On steeper slopes, an intercept drain (a French drain) uphill of the house can capture water before it reaches the foundation.
Burnaby has postwar ranchers and split-levels, 1970s and 1980s construction, and significant newer infill and redevelopment. The older homes have the same perimeter drain aging issues as the rest of Metro Vancouver — clay tile and early corrugated pipe reaching end of life. The newer construction usually has modern perimeter drainage, but the sloped sites can still have surface and yard drainage problems that were not fully addressed during the build.
Water in a basement is rarely just one problem. It can be a failed perimeter drain letting groundwater in at the footing, a crack in the foundation wall, or a waterproofing membrane that has broken down over decades. We start with a drain camera inspection to see what is happening inside the pipe, then determine whether the fix is a wet basement repair, basement waterproofing with an exterior membrane and drainage board, or damp proofing of the foundation wall to stop moisture wicking through the concrete. For older Burnaby homes with original drainage, the answer is often a combination of drain repair and waterproofing — and we show you the camera footage before recommending anything.
Most people never think about their drainage system until it stops working. Here is what a complete system looks like — and where water goes when everything is doing its job.
Rain on roof
Gutters collect it
Downspout
Carries it down

Protects the wall

Discharged safely
A working drainage system moves water off the roof, away from the foundation wall, and out to a safe discharge point — before it can build up against your foundation.

These are the services we are most often called for in Burnaby. Each links to a page with more detail on what is involved.
For each of the services below, we have a dedicated Burnaby page covering what the work involves, what the local conditions mean for that service, and answers to common questions from homeowners in Burnaby.
Water runs down the slope toward my Burnaby house. What can I do?
An intercept drain (a French drain) placed uphill of the house can capture surface and shallow subsurface water before it reaches the foundation, and carry it around the house to a safe outlet. Combined with grading that directs the remaining surface water away, this is the standard fix for sloped properties.
My basement is wet only on the downhill side. Is that the perimeter drain?
Often yes — water builds up against the downhill foundation wall because the perimeter drain cannot keep up or has failed there. A camera inspection confirms whether the drain is the cause and whether a targeted repair or a fuller replacement is needed.
