Interior Underpinning and Foundation Reinforcement (Hamilton)

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. Repeat process for second underpin.

Establish location of footing and mark out on floor. Excavate to required depth. Establish soil strength, install rebar grid. Cast in place using 25 MPa concrete at minimum strength. Vibrate concrete to top of form and float to glass finish. After 48 hours, return to remove forms. Dispose of all debris.

All work(s) to be completed to engineering specifications.
