Interior vs exterior waterproofing in Muskoka
Interior manages water at the wall. Exterior keeps water off the wall. Muskoka homes usually need one or the other, and granite often decides which.
Interior: collect and pump
We open the slab at the perimeter, set a drain, line the wall and pump the water out. It is faster, usually less costly, and kinder to decks and pines. It is the right call for cove-joint leaks and cottages you cannot empty for a week of excavation.
Exterior: stop it outside
We dig to the footing and rebuild the barrier when bedrock and access allow. Best when the wall face is wet or the original membrane never existed. It takes longer and costs more because excavation on the Shield is the job.
How we choose
Entry point, granite, how long you plan to own the place, and whether the yard can take a trench. We will tell you if a cheaper interior system would only hide a wall that is still taking a beating.
