When it comes to modern perimeter drains, Victoria, BC houses typically have lengths of PVC piping that are perforated on the top to allow water to enter from above. They are fitted with a mesh sleeve to help keep out dirt, and then gravel is poured on top and across a slope that will encourage water to move toward the perimeter drain pipe. Then, the soil is typically placed on top to conceal the installation. If the inspection process reveals that one part of the drainage system is damaged but the rest is in fairly good shape, our plumbers can carry out a localized repair or clear the blockage with hydro jetting rather than replacing the entire system.
If we're talking about older perimeter drains, Victoria, BC homeowners may find that instead of PVC, they have clay or concrete piping installed. There's nothing inherently wrong with that, but those materials are no longer used because they're just not as durable, long-lasting, and easy to work with as plastic. If you're experiencing problems with older materials, it's likely the whole system will need replacement.
