Our focus is on effective solutions, professional workmanship, and long-term protection for your home's foundation.
Internal drainage system
- Concrete Demolition: Precision jackhammering of the concrete floor slab along perimeter foundation walls to create an open trench
- Excavation & Trench Prep: Removal of existing sub-base soil to precise grade depth to accommodate system piping and clear aggregate.
- Drainage Pipe Installation: Placement of perforated weeping tile pipe wrapped in filter fabric along the footing, pitched toward the collection basin
- Dimple Board Application: Installation of heavy-dutypolyethylene drainage membrane (dimple board) secured flush against the interior foundation wall, tucked into the trench below slab level to channel wall seepage directly into the tile
- Gravel Backfill: Surrounding the perforated drain pipe with clean ¾" washed clear stone for maximum water flow and filtration
- Concrete Restoration: Re-pouring high-strength concrete over the trench area, troweled smooth to match the existing floor finish flush with the wall
Internal Artery Pipe Extension
- Trench Excavation: Jackhammering concrete slab along designated floor paths to carve an internal drainage trench linking targeted trouble areas to the main pit.
- Perforated Pipe Installation: Laying 4" perforated weeping tile pipe wrapped in a geotextile filter sock within the concrete trench.
- Sump Pump Connection: Pitching and running the 4" pipe run directly into the sump pit to ensure continuous gravity-fed drainage from all sections
- Gravel Backfill & Slab Repair: Bedding the pipe run in 3/4" clear crushed stone and re-pouring high-strength concrete flush with the existing floor level.
Additional footage-External Foundation Waterproofing & Excavation
- Excavation : Mechanical and manual trenching down to the footing along designated exterior walls to fully expose the foundation, utilizing proper safety and protection
- Surface Preparation & Crack Repair: Wire-brushing and pressure cleaning the exposed masonry wall. V-cutting all structural cracks, tie-rod holes, and voids, packing them with non-shrink hydraulic cement.
- Elastomeric Waterproofing Membrane: Trowel/spray application of heavy-duty Aqua-Block liquid asphalt rubber coating across the bare foundation face to establish a seamless waterproofing seal.
- Protective Barrier: Full application of 6 mil polyethylene sheet over the cured Aqua-Block membrane as a protective slip-sheet against soil movement.
- Dimple Board Installation: Heavy-duty, high-density dimple board mounted over the plastic layer, secured with top termination strips and concrete anchors to create an air-gap drainage plane.
- Weeping Tile Replacement: Removal of old/clogged drainage pipe and installation of new 4" perforated weeping tile wrapped in a filter fabric sock along the footing.
- Crushed Stone Backfill: Placing a deep layer of 3/4" washed clear crushed gravel over and around the new weeping tile for maximum groundwater flow and silt filtration.
- Backfill & Compaction: Backfilling the remaining trench with soil, tamping in layers, and grading the top surface at a positive slope away from the foundation.
