Concrete coatings and parkade waterproofing in Maple Ridge.

Maple Ridge

Flat land near the river behaves like Richmond

The industrial land in Maple Ridge and Pitt Meadows sits on Fraser floodplain, and slabs on grade there behave much the way Richmond's do: groundwater is close, vapour moves up through the concrete continuously, and a coating that cannot handle that lifts off in blisters within a year or two.

So the first thing we do on flat-land jobs here is measure, not assume. Relative humidity probes in the slab tell us whether a standard primer is viable or whether the job needs a vapour-tolerant build. Pricing that in at the start is far cheaper than discovering it after the floor has been installed once.

Higher up the slope the picture changes completely — newer multi-family construction with suspended parkade slabs, where the issue is not groundwater but ordinary membrane life and the quality of the original detailing at curbs, drains and joints.
