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.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
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.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
Drainage board over the membrane channels water to the footing drain rather than letting pressure build against the wall.
Each service below is scoped specifically to exterior waterproofing, not a generic waterproofing menu with the name swapped in.
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.
Soil sloping toward the foundation sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
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.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Active pooling against the foundation is flagged for priority scheduling.
Most Le Roy, IL exterior assessments are scheduled within a few days given the scope of a proper walk.
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.
