Carbon Fiber Foundation Reinforcement with Underpinning (Hamilton)

Break open concrete floor and expose footing in proposed carbon fiber reinforcement installation areas. Remove all debris from concrete foundation wall and clean thoroughly. Expose sill plate/joist work and prepare for hardware mounting. Drill 1″ hole in concrete footing and clean debris from hole.

Generously cover concrete wall with resin and install carbon fiber strips directly to foundation wall. Run carbon fiber overtop of exposed footing and curl base of strip into proposed underpinning. Fasten top of carbon fiber into sillplate/joistwork and tighten hardware.

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 and fill exterior blockwork with slurry grout.

Once cured, remove timber forms and fasten drainage board to foundation wall using concrete anchors. Install a fresh 4″ perforated weeping tile system with filter cloth.

Connect fresh weeping tile system into existing drain works. Cover weeping tile with 3/4″ gravel and reinstall concrete floor.

Remove and dump all debris. All labour and materials included.
