About
Drainage work that starts with where water is moving
Delta sits on Fraser River floodplain soil with a naturally high water table and limited gravity fall. We plan around that behaviour, then recommend a path that matches the house you actually have.
How we work
Delta Perimeter Drainage is a local contractor focused on keeping basements dry on Fraser River floodplain lots. We work across Ladner, Tsawwassen, North Delta, Sunshine Hills, and Boundary Bay, from older clay tile systems to newer builds that still fight a high water table. Our approach is plain: map where water is moving, explain what we find, price the real scope, and restore the yard. We do not sell a full dig when a grade fix or sump upgrade is the honest first step. If you are seeing water, damp walls, constant sump cycling, or an inspection flag on weeping tile, we can help you decide what to do next.
Most drainage conversations go wrong when someone quotes a full perimeter dig before anyone has mapped floor wet versus wall damp versus yard ponding versus sump behaviour. We reverse that. You tell us the neighbourhood and symptoms. We respond with a practical next step: surface grade, camera, sump upgrade, or full weeping tile replacement.
Surface fixes and sump upgrades are first-class options here, not consolation prizes. If a narrower scope solves the problem, that is the recommendation.
What the process feels like
- 01
Describe the water path
Tell us where water shows up: floor, walls, yard, sump behaviour, or an inspection note. Photos help.
- 02
Site read in Delta
We walk grade, downspouts, and access, and may recommend camera inspection if the line can be entered.
- 03
Written scope and price
You get what is included, what is assumed, timeline, and total cost before crews mobilize.
- 04
Install and close the yard
We dig, install, test discharge, backfill, and leave grade that sheds water away from the footing.
What you should expect
- Clear scopes before major digs. Assumptions, unknowns, and what could change after opening the trench are named up front.
- Honest dig-versus-surface talk. We do not treat every wet basement as a full perimeter sale.
- Floodplain literacy. Recommendations respect high water table, silt, and limited fall on flat lots.
- Business-hours follow-up. Estimate requests get a practical response during regular weekday hours. Ask if you need current licensing and insurance documents for your file.
