Saw cut asphalt and excavate to footing. Excavate underpin by hand and clean underside of footing with wire brush. Apply masonry adhesive to underside of footing. Once underpin is carved and prepared, build and install timber forms to accommodate a positive concrete adhesion to the underside of existing footings (non-grout, overflow method) allowing for a void-less encapsulation of existing structure to fresh underpin. Fill forms with 25 MPa concrete until full and install needle vibrator. Once cured, remove timber forms.
Repair all cracks and masonry voids in foundation wall below grade. Once cured, apply AB-720-38 rubberized membrane to repair area. Add a layer of mastic mesh, another layer of AB-720-38 rubberized membrane, a layer of 12m plastic and fasten drainage board to grade with termination straps and concrete anchors.
Replace weeping tile system within repair areas and cover with 6″ of 3/4″ clear gravel. Backfill and power tamp dirt.
