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.
Crews are trained in excavation depth, membrane application, and footing drain installation specific to exterior systems.
Initial exterior assessments, requiring a full perimeter walk, are typically scheduled within a few days across our service area.
Quotes break out excavation footage, membrane material, footing drain installation, and backfill separately in writing.
We apply rubberized asphalt or sheet membrane rated for permanent below-grade exposure, not a consumer coating that degrades in a season or two.
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 over the membrane channels water 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.
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.
Sealing from the exterior addresses hydrostatic pressure at the point of entry rather than relying solely on interior injection.
Here's what happens between your call and a completed exterior fix.
Active pooling against the foundation is flagged for priority scheduling.
Technicians walk the full property perimeter before recommending excavation, checking grading and downspout placement.
Pricing is itemized by excavation footage and membrane material, in writing before any digging begins.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included.
What Highland, IL customers are saying after their exterior waterproofing service.
"They found our footing drain had completely collapsed after thirty years — explains why 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."
"They explained why interior injection alone wasn't going to solve our specific problem before recommending exterior work."
