Sub-Slab French Drain Channels
Perimeter slab removal, trench excavation beside the footer, washed drainage stone bedding, and rigid perforated pipe pitched to a sealed sump liner.

Specialized Waterproofing & Foundation Scopes of Work
Interior Perimeter Drainage & Hydrostatic Relief
When water rises beneath the basement slab or enters at the wall-to-floor cove joint, interior coatings alone fail under hydrostatic pressure. Our sub-slab systems relieve pressure directly at the footer zone.
Wall-to-Floor Cove Seepage Flanges
Dimpled drainage matting installed at the base of block or poured concrete walls to direct weep-hole moisture safely beneath the restored slab.
Window Well Drains
Vertical tap-ins connecting below-grade egress or basement window wells directly into the interior perimeter drainage loop.
Sump Pump Systems & Freeze-Resistant Discharge
A perimeter drain is only as dependable as the mechanical system pumping collected water away from your foundation.
Sealed Perforated Sump Basins
Airtight, radon-compatible lids with gasketed cord grommets to prevent basin evaporation, odors, and debris intrusion.
Dual Cast-Iron & Battery Backup Configurations
Primary AC submersible pumps paired with secondary float switches and deep-cycle battery backups for storm outage resilience.
Dedicated Exterior Discharge & Ice Guards
Rigid PVC discharge lines fitted with quiet check valves, air-gap freeze relief fittings, and buried yard extensions away from the foundation perimeter.
Crack Injection & Structural Wall Stabilization
Poured concrete shrinkage cracks and bowing masonry block walls require material-specific repair methods.
Low-Pressure Polyurethane & Epoxy Injection
Expanding hydrophobic foams for active non-structural water leaks in poured walls, or structural epoxy resin where monolithic bonding is specified.
Carbon Fiber Reinforcing Straps
Epoxy-bonded carbon-kevlar grid straps anchored to the sill plate and slab to counter inward soil pressure on mildly bowed walls.
Crawl Space Encapsulation
Reinforced polyethylene liner installation over dirt crawl spaces, sealed piers, insulated rim joists, and mechanical moisture control.
