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

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
Crews are trained in proper excavation depth, membrane application technique, and footing drain installation specific to exterior waterproofing systems.
Initial exterior assessments, which require walking the full property perimeter, are typically scheduled within a few days.
Quotes break out excavation linear footage, membrane material, footing drain installation, and backfill/regrading separately, in writing.
Drainage board installed over the membrane channels water down to the footing drain rather than letting hydrostatic 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 goes over the membrane to create a channel for water to travel 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 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.
Here's what happens between your call and a completed exterior fix.
Photos of the affected exterior area, texted ahead of the visit, help the technician plan equipment needs before arriving.
Most Princeton, IL exterior assessments are scheduled within a few days given the scope of a proper perimeter evaluation.
A full grading and drainage evaluation identifies whether the fix needs full excavation, footing drain repair, or grading correction alone.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
Real feedback from Princeton-area customers who called us for exterior waterproofing.
