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.
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.
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.
Older homes often have drains that have silted in or collapsed over decades — we assess and replace where compromised.
Soil sloping toward the foundation sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
We install well drains tied into the footing drain system with a clear cover to reduce debris.
Sealing from the exterior addresses hydrostatic pressure at the point of entry rather than relying solely on interior injection.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Photos of the affected area, texted ahead, help the technician plan equipment before arriving.
