Flood Restoration in Coquitlam
Burke Mountain fills from a window well. Maillardville fills from a floor drain. Both are Coquitlam floods.
Westwood Plateau and Ranch Park wells dump volume at the uphill wall of a deep basement. Maillardville and a lot of Central Coquitlam bring dirty water up through the laundry drain in a multi-day rain. Austin Heights sits with the older houses: copper leaks and footings, not a brand-new well on a cut slope. The mountain also sends water down to the flat grid, so a street-side inlet on a lower lot can be the hill's runoff arriving late.
We pump either flood the day it happens. The rebuild splits after that. Dirty drain water removes more material. Hill concrete stays cold and takes longer to give up its moisture. If both a well and a drain ran in the same storm, they get two notes. One crew can still do the visit.
Burke Mountain well waterline at the uphill basement wall
The well is the inlet. We photograph it, bail it if it is still holding water, and chalk how high the basement went. Batts on that wall come out. Laminate that swelled from the outside wall inward comes up.
The middle of the room can look almost okay while the wall cavity is soaked. Drying is aimed at that wall, not at a fan in the centre of the carpet. Westwood houses cut into the same slope get that same aim. We do not close the wall because the pump-out looked finished.
Maillardville drain waterline at the laundry floor drain
Older laterals surcharge, and the floor drain is where you see it. By the time it reaches the laundry it is often dirty. Pad, the bottom of the board, and anything porous that soaked come out on a contained path.
Central Coquitlam basements with the same drain get the same category. We photograph the drain and the waterline on the tub or the standpipe. A plumber owns a failed backwater valve. We own the water that already left it and the finishes it ruined.
Austin Heights flood waterline on an older basement slab
These basements were not waterproofed to a new hillside standard. A footing leak and a supply leak can both put water on the floor, and they are not the same restore. We meter the wall and open the wet edge so the bay can dry.
Fir upstairs is a separate material. If the flood stayed in the basement, the main floor can often remain in use. If a bathroom above let go and the ceiling failed into the basement, both assemblies are on the sheet. Ranch Park's older stock follows that split more than its new wells do.
Central Coquitlam street-side waterline after the hill sheds
The lower grid receives what the mountain sends. The inlet might be a stairwell, a window at grade, or a drain that could not keep up. We photograph the street side and the waterline inside so the file shows the path.
Pump-out still comes first. Then the category. Surface water that crossed soil is not treated like a clean supply line. Insulation and floor coverings that sat in it come out. The dry starts once the debris is gone, not while we are still carrying wet pad through the kitchen.
