The Ultimate Outer Defense for Pennsylvania Foundations
When an interior basement space is fully finished with expensive hardwood, drywall, and custom entertainment areas, addressing water intrusion from the outside is the ultimate solution. Over time, original builder asphalt dampproofing coatings degrade, leaving porous masonry vulnerable to saturated Pennsylvania soils.
Stop Ground Moisture at the Source Across PA
Protect your high-value finished basement with commercial elastomeric foundation coatings and exterior weeping tiles.
Call 717-402-9081Full exterior waterproofing involves excavating the foundation perimeter down to the original footings, well below Pennsylvania's 36-inch frost line. Masonry is pressure-washed, tuckpointed, and coated with a thick elastomeric rubber membrane that stays flexible through seasonal freezing. A dimpled drainage board is then applied to relieve hydrostatic pressure and direct water into an exterior weeping tile.

Exterior waterproofing stops water before it ever contacts the masonry. It is the premier choice when preserving finished basements and preventing moisture penetration entirely.
Excavation proceeds entirely down to the footing level, typically 6 to 9 feet below grade, ensuring complete treatment below Pennsylvania's deep winter frost line.
We apply commercial elastomeric rubberized polymer membranes up to 60 mils thick that expand and contract with temperature swings without cracking.
Dimpled drainage boards create a permanent air gap against the foundation. Water hitting the board instantly drops to the footing drain, eliminating lateral hydrostatic pressure.
Full exterior perimeter excavation, wall sealing, and backfilling typically take one to two weeks, depending on property access and foundation size.
We backfill the bottom trench with washed drainage stone and clean gravel, ensuring fast drainage away from the wall rather than compacted muddy soil.
Yes. Efflorescence is caused by mineral salts carried through the block by evaporating water. Halting exterior moisture permanently prevents efflorescence from reforming.
Deep excavation is best performed during thawed ground conditions from early spring through late autumn to ensure proper membrane adhesion and curing.
