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

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
We don't treat exterior work as a bigger version of interior injection — it's a distinct discipline requiring different technique and specialized equipment.
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.
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.
Older homes often have drains that have silted in or collapsed over decades — we assess and replace where compromised.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete fix.
We install well drains tied into the footing drain system with a clear cover to reduce debris.
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.
Photos of the affected area, texted ahead, help the technician plan equipment before arriving.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
Pricing is itemized by excavation footage and membrane material, in writing before any digging begins.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
