THE SITUATION
Why This Service Matters
Have you noticed seepage through the wall face on a Wasaga-area foundation, not just a line at the floor? Many beach and inland homes see this when the original membrane failed, or when tile silted in sand. Interior work may only manage the symptom. Exterior waterproofing is designed to stop water before it reaches the concrete.
We dig to the footing where access allows, clean the wall, repair cracks, apply a membrane and set new weeping tile in stone. On Georgian Bay, a high water table can keep the trench wet. That changes how we plan the day and how we protect the hole.
A wall that wets through the face will keep staining finishes if you only collect water at the floor. Exterior work resets the barrier and the tile that was supposed to relieve pressure, which helps protect comfort and value.
It also makes sense if you intend to stay, or to use a seasonal place more months of the year. You pay more up front than a one-wall interior drain, and you avoid opening the same elevation again because the outside system was left failed.
This is the more complete barrier and the higher-cost option, often $100 to $250 or more per linear foot. It is a worthwhile choice when you plan to keep the property for years, or when the outside system is no longer doing its job.
Exterior work is cleaner once the ground has thawed — late spring through fall. If you are leaking in January, we can often start interior work and schedule the dig when the soil will compact. Get in touch and we can talk through timing for your lot.

You want water stopped before it sits against the foundation
THE WORK
What the Job Involves

New exterior tile, stone, fabric and compacted backfill
HOW WE WORK
How We Complete the Work
We confirm access: decks, plantings, how wet the sand sits and how deep the footing is. That is what drives time and cost more than the membrane brand, so we walk it with you first.
We excavate the wet elevations, repair cracks, and apply the membrane so snowmelt and groundwater cannot sit against the concrete.
New perforated tile goes in washed stone, wrapped where fines would pack the pipe, and sloped to a storm connection or a sump that leaves the lot.
Backfill is compacted in lifts. The job is not finished when the membrane is on. It is finished when the grade sheds water away from the house and you can use the yard again.
COST
What It Typically Costs
Exterior waterproofing in Wasaga Beach is commonly $100 to $250 or more per linear foot, depending on depth, access and how much landscaping we move. Full-house excavation costs more than one or two walls.
If only one elevation has failed, we work that wall. We will not open the whole perimeter unless the rest of the tile is in the same condition. That helps you put the budget where it will do the most good.

Excavation, membrane, new tile and compacted backfill. Sand and access change the number.
Get a written quoteCommon Mistakes to Avoid
01
Coating the inside while the exterior tile is silted in sand. Pressure will find the next crack.
02
Digging in frozen ground and calling the backfill done. Frozen soil does not compact. We prefer thawed soil for lasting results.
03
Dumping sump discharge beside the new membrane. The water has to leave the property.
