Have you experienced a wet basement? This can be costly, cause you stress, and even put your family's health at risk.
Get Your Free Consultation Today!Exterior basement waterproofing is the gold standard of foundation water management. Rather than collecting water that has already entered your walls, exterior waterproofing stops water before it ever reaches your foundation. We excavate around the full perimeter of your home down to the footing level, clean and repair the foundation wall surface, apply a waterproof membrane, install a drainage board and weeping tile system, and backfill with clean drainage stone. For Chambersburg and Franklin County homeowners dealing with persistently wet basements, exterior waterproofing is the most permanent and comprehensive solution available.
Our Process
Perimeter Excavation
We excavate around the exterior of your foundation down to the footing level — typically six to ten feet deep. Excavation is done carefully to avoid damaging underground utilities, landscaping, and adjacent structures.
Foundation Wall Preparation
With the wall exposed, we clean off decades of dirt, old tar coatings, and deteriorated parging. Any cracks are repaired with hydraulic cement or epoxy injection before waterproofing is applied.
Waterproof Membrane Application
We apply a high-performance rubberized asphalt membrane to the entire exposed foundation surface. A drainage board is applied over the membrane to protect it and channel water downward to the weeping tile.
Weeping Tile & Drainage Stone Installation
Perforated drainage pipe is installed in a bed of clean crushed stone, wrapped in filter fabric. This system collects water before it reaches the wall and routes it away from the foundation.
Backfill, Grading & Restoration
We backfill in compacted lifts and restore the grade to slope away from your home. Damaged landscaping and hardscaping are restored as much as possible. We provide a full warranty on the system.
Benefits
- Foundation Cracks — repairs existing wall cracks before applying the membrane
