Interior Drain Tile in Langley
How Interior Drain Tile Works
Interior drain tile installs along the inside perimeter of your basement, not outside the house. We cut a channel into the concrete floor next to the foundation wall, lay perforated pipe in a bed of gravel below slab level, and connect it to a sump pit where a pump lifts the water out and discharges it away from the foundation. The channel gets capped with new concrete once the pipe and gravel are in.
Because the whole system installs from inside the basement, it doesn't touch your yard, landscaping, or driveway, which makes it a faster, less disruptive alternative to exterior perimeter drain replacement.
Interior Drain Tile vs Perimeter Drain Replacement
Exterior perimeter drains sit outside the foundation at the footing, catching water before it touches the wall. Interior drain tile catches water after it's already reached the inside face of the wall or the floor joint, which means the wall itself stays exposed to moisture on the outside even though your basement stays dry. That difference is why interior systems cost less and install faster: no excavation, no landscaping to restore, no weather delays digging in wet Fraser Valley soil.
Interior drain tile is the right call when exterior excavation isn't practical, a finished landscape, a shared property line, or a slab-on-grade addition blocking access, or when the existing exterior drains are functioning and the issue is isolated seepage rather than a fully failed perimeter system.
Cost and Installation
Interior drain tile typically runs $30–$230 per linear foot depending on basement size, concrete thickness, and access, with a full-perimeter interior system landing in the $3,000–$10,000 range for an average home. If a sump pump isn't already in place, add roughly $500–$1,500 for the pit, basin, and pump. Most jobs take one to two days: cutting the channel, laying pipe and gravel, connecting to the sump, and pouring new concrete over the channel, with no long cure-time wait beyond the concrete setting.

FAQ
Common Questions About Interior Drain Tile
Do I need a permit for foundation repair in Langley?
Crack injection and interior drainage work generally don't require permits. Structural repairs and excavation affecting the building envelope may require permits from the Township of Langley or City of Langley depending on your address and scope. We confirm permit requirements as part of the quote so there are no surprises.
Why do Langley homes get foundation cracks?
Three local factors: Fraser Valley clay-rich soils that expand when saturated and shrink in dry summers, heavy October-to-April rainfall that loads soil against foundation walls, and the age of the housing stock — much of Langley, from Brookswood's 1970s lots to Walnut Grove's 1990s subdivisions, has perimeter drains near or past their service life. Add freeze-thaw cycles and you get the vertical shrinkage cracks and seepage we see in most inspections.
Do you serve areas outside Langley?
Yes — we cover all of Langley including Walnut Grove, Willoughby, Brookswood, Murrayville, Fort Langley, and Aldergrove, plus Surrey, Abbotsford, Maple Ridge, and White Rock. Call to confirm availability for your address.
How much does interior drain tile cost?
Interior drain tile typically runs $30–$230 per linear foot depending on basement size, concrete thickness, and access, with a full-perimeter interior system landing in the $3,000–$10,000 range. If a sump pump isn't already in place, add roughly $500–$1,500 for the pit, basin, and pump.
When does interior drain tile make more sense than exterior perimeter drain replacement?
When exterior excavation isn't practical, a finished landscape, a shared property line, or an addition blocking access, or when the existing exterior drains are functioning and the issue is isolated seepage rather than a fully failed perimeter system. It also costs less and installs faster since there's no excavation or landscaping to restore.
Will interior drain tile installation disrupt my yard?
No. The whole system installs from inside your basement along the interior perimeter, so it doesn't touch your yard, landscaping, or driveway. Most jobs take one to two days.
Can I finish my basement after interior drain tile is installed?
Yes. Interior drain tile runs along the perimeter under the floor, capped with new concrete once installed, and doesn't interfere with finishing the rest of the basement. If anything, installing it before you finish is the better order of operations: it's much cheaper to address seepage before drywall and flooring go in than to tear them out later.
