About this detail

This assembly details a waterproofed concrete foundation wall cast against a soil retention system of steel piles and wood lagging. The waterproofing layers include an SCS composite sheet membrane, a 1/4-inch protection board, and an adhesive-faced CJ tape with a 12-inch wide Preprufe SCS geotextile strip centered over butt joints. An injection port assembly and hydrophilic grout are integrated for compartmentalized water mitigation, positioned to avoid end laps. Additional layers consist of geotextile fabric, mesh, a 10-mil plastic film, and backfilled soil.
