When water reaches your foundation from the outside, through poor grading, a failed membrane, or saturated soil, the fix belongs outside too, not just masked from the inside.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
Certification covers grading assessment and rubberized membrane application to manufacturer spec, verified on every job.
Active pooling against the foundation moves to priority scheduling ahead of routine appointments.
No surprise charges for unexpected utility lines or rock encountered during excavation — those are flagged and discussed first.
Drainage board over the membrane channels water to the footing drain rather than letting 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.
We excavate along the affected wall section down to the footing, prep the surface, and apply a rubberized membrane rated for permanent below-grade exposure. This is the most thorough exterior fix available and typically carries the longest service life.
A footing drain intercepts groundwater at the base of the foundation and carries it away before it can build pressure against the wall.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete fix.
Window wells without proper drainage collect and hold water against a vulnerable point in the wall — often the source of a leak that seemed to come from nowhere.
Cracks and cold joints exposed during excavation get treated directly 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 staining on the wall, saturated soil — and dispatch routes a crew equipped for exterior assessment.
Technicians walk the full property perimeter before recommending excavation, checking grading and downspout placement.
A full grading and drainage evaluation identifies whether the fix needs excavation, drain repair, or grading correction alone.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included.
