When water is reaching your foundation from the outside — through poor grading, a failed membrane, or saturated soil — the fix belongs outside too, not just inside masking the symptom.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
Crews are trained in proper excavation depth, membrane application technique, and footing drain installation specific to exterior waterproofing systems.
Local crews understand your region's soil composition and typical frost depth, both of which affect excavation planning.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
Footing drains are set in washed gravel and wrapped in filter fabric to resist silt clogging over the system's service life.
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, clean and prep the existing foundation surface, and apply a rubberized waterproofing membrane rated for permanent below-grade exposure. This is the most thorough exterior fix available and typically carries the longest service life of any waterproofing method.
A footing drain intercepts groundwater at the base of the foundation and carries it away via gravity or a connected sump system 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 exterior fix.
We install window well drains tied into the footing drain system, plus a clear cover to reduce debris accumulation.
Sealing from the exterior addresses hydrostatic pressure at the point of entry rather than relying solely on an interior injection to manage it after the fact.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Photos of the affected exterior area, texted ahead of the visit, help the technician plan equipment needs before arriving.
Most Keego Harbor, MI exterior assessments are scheduled within a few days given the scope of a proper perimeter evaluation.
Utility locates are scheduled ahead of excavation as standard practice, not an afterthought.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
