Pipe Penetration Sealing for a Construction contractor

A construction contractor had cored through waterproof concrete walls and soffits to install service penetrations for the electrical, gas, drainage, sprinkler systems, air conditioning and water services which meant that these penetration were not fireproof or watertight.

Total specialist provided a solution to the problem, which involved plugging the annulus between the host concrete and pipe using a F120 fire rated concrete repair mortar and allowed to cure. The pipe penetrations were then made watertight by drilling through the plugging mortar and then injecting a structural waterproof polyurethane injection resin. The holes were then made good with a F120 fire rated concrete repair mortar.
