Exterior waterproofing addresses the source directly: excavation, membrane application, and footing drainage designed to keep water away from the wall in the first place.

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
Crews are trained in proper excavation depth, membrane application technique, and footing drain installation specific to exterior waterproofing systems.
Local crews understand your region's soil composition and typical frost depth, both of which affect excavation planning.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
Drainage board installed over the membrane channels water down to the footing drain rather than letting hydrostatic pressure build against the wall.
Each service below is scoped specifically to exterior waterproofing, not a generic waterproofing menu with the name swapped in.
Drainage board goes over the membrane to create a channel for water to travel down to the footing drain instead of pressing against the wall. This is the most thorough exterior fix available and typically carries the longest service life of any waterproofing method.
Older homes often have footing drains that have silted in or collapsed over decades — we assess existing drain condition and replace where compromised.
Soil that slopes toward the foundation instead of away from it sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
We install window well drains tied into the footing drain system, plus a clear cover to reduce debris accumulation.
Cracks and cold joints exposed during excavation get treated directly at the source, from the outside, before the membrane goes over them.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Describe what you're seeing from outside — pooling water, visible efflorescence on the wall, soil that stays saturated — and dispatch routes a crew equipped for an exterior assessment.
Technicians walk the full property perimeter before recommending excavation, checking grading, downspout placement, and existing drainage.
A full grading and drainage evaluation identifies whether the fix needs full excavation, footing drain repair, or grading correction alone.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included where disturbed.
What Saint Bonifacius, MN customers are saying after their exterior waterproofing service.
"They found our footing drain had completely collapsed after thirty years — explains why the interior fixes never fully worked before."
"Regraded the whole side yard and extended our downspouts as part of the job. Haven't seen water against that wall since."
"Excavation crew was careful with our landscaping and put everything back better than it was before."
"Appreciated that they explained why interior injection alone wasn't going to solve our specific problem before recommending exterior work."
