In order to stop groundwater from seeping onto the basement floor, we jackhammered out the concrete along perimeter area. We hauled away the old concrete and related debris, and dug a trench, where we laid out filter cloth to minimize sediment getting into system. We laid the WaterGuard system (including clean-out ports) on the foundation footing, and backfilled the trench with river rock stone. We then mortared back the floor. Their system will drain into an existing sump pit.
