To use the Gebbie Tech System, you must use the Gebbie Tech Steel Stiﬀener and Gebbie Tech Rubber Gaskets and follow the detailed instructional video and process booklet . The Gebbie Tech system is the approved method of vertical concrete wall crack repair using Roadware 10-Minute Concrete Mender (as listed in Roadware's data-sheet).
Roadware 10-Minute Concrete Mender™ is the approved product to use with this ﬁxing system because of the high-quality composition of the urethane resin. Alternative products might not work as well, due to the diﬀering chemical composition. Roadware 10-Minute Concrete Mender™ is not part of the kit and is sold separately, refer to www.concretemender.com.
A major advantage of the system is the curing time of the Roadware 10-Minute Concrete Mender™. This enables wall crack repairs to be carried out in one day. Over 44 yards have been achieved in one day, by a two-person crew.
Alternative processes can take up to three days to repair a concrete wall, due to the method of application, and their curing time. The eﬃciencies of the Gebbie Tech System include the reduction in both labour and downtime for additional contractors such as painters. Warehouses, bridges and commercial buildings can be re-accessed and operational quickly, due to the fast cure times.
