When water is reaching your foundation from the outside — through poor grading, a failed membrane, or saturated soil — the fix belongs outside too, not just inside masking the symptom.

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
Certification covers grading assessment, drainage board installation, and rubberized membrane application to manufacturer spec.
Active water intrusion visible from outside — pooling against the foundation, saturated soil — moves to priority scheduling.
Quotes break out excavation linear footage, membrane material, footing drain installation, and backfill/regrading separately, in writing.
Drainage board installed over the membrane channels water down to the footing drain rather than letting hydrostatic pressure build against the wall.
We don't run a one-size-fits-all playbook — every exterior waterproofing job starts from these core service components, adapted to what your property actually needs.
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.
A footing drain intercepts groundwater at the base of the foundation and carries it away via gravity or a connected sump system before it can build pressure against the wall.
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.
Photos of the affected exterior area, texted ahead of the visit, help the technician plan equipment needs before arriving.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
Utility locates are scheduled ahead of excavation as standard practice, not an afterthought.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included where disturbed.
Real feedback from Lebanon-area customers who called us for exterior waterproofing.
"They found our footing drain had completely collapsed after thirty years — explains why the interior fixes never fully worked before."

"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."
