Interior drainage
The slab edge is cut back, a perforated pipe goes in clear stone beside the footing, and a membrane carries wall seepage into it. Runs in any season and leaves your yard alone.

What each repair actually involves
Exterior waterproofing
The wall is dug out to the footing, cleaned, sealed with a rubberised membrane and covered with dimple board, with a new drain in clear stone. The only method that keeps the wall itself dry.
Exterior waterproofing
Foundation crack repair
Ports along the crack, the face sealed between them, resin injected at low pressure so the crack fills front to back instead of being patched on the inside.

Weeping tile replacement
Clay tile around older Collingwood houses silts up or collapses. Replacement is perforated pipe bedded in clear stone and wrapped in filter fabric so it does not fill with fines again.

Sump pumps and pits
A pit sized for the water your house actually produces, a pump on a solid base clear of silt, a free-swinging float, a check valve, and a discharge line that ends far enough away to matter.
Sump pumps and pitsNot sure which one?
That is the normal starting point. Book the assessment and we will tell you what the wall is doing — including when the answer is that you do not need us yet.

What you are seeing, and where to read next
| What you see | Most likely cause | Start here |
|---|---|---|
| Water along the joint where the floor meets the wall | The drain at the footing is not carrying water away, or the water table has come up | Interior drainage |
| A wet line down one spot on a poured wall | A shrinkage or settlement crack through the wall | Crack repair |
| A whole wall damp, with efflorescence across it | The wall is saturated from outside; the membrane and drain have failed | Exterior waterproofing |
| Water rising through the slab in the middle of the floor | High water table, no functioning sump | Sump pump and pit |
| The pump runs constantly, or the pit fills faster than it empties | Undersized pit or pump, or a discharge line that returns water to the same ground | Sump pump and pit |
| Nothing inside, but the yard is soft and the downspouts flood | Surface water, and possibly a collapsed drain | Weeping tile |
