Bench Pinning Underpinning with HSS Posts (Hamilton)

On inside of basement, prepare perimeter of repair area and remove all debris to clear access. Begin bench pinning sections around proposed interior foundation walls. Install angle of repose to engineered specifications and install vertical rebar (bent at a 90 degree) into existing footing/foundation walls as well as vertical rebar inserted into unexcavated ground at base of bench pin (leaving the underside of existing footing undisturbed in benching area).

Install multiple levels of horizontal rebar into bench pins and tie into vertical rebar creating a mesh pattern. Once complete, form with timber and install 25 mPa concrete into forms. Vibrate with needle vibrator to ensure complete encapsulation of form. Once cured, remove forms. Repeat process until complete.

Once perimeter is complete begin excavations by hand and install HSS posts into concrete footings.
