A unique composite sheet Preprufe SCS membrane applied vertically to the soil retention system serving as a channel to contain the flow of the post-injected grout.
Preprufe® SCS is a unique blindside waterproofing system specifically developed to provide a high performance waterproofing solution for shotcrete foundation walls.
It is applied vertically to timber lagging or other soil retention systems. Shotcrete is then placed directly against the geotextile side of the membrane. Unlike conventional waterproofing systems, Preprufe SCS waterproofing system has injection ports to facilitate grout injection into a pre-created cavity space, forming an in-situ monolithic grout membrane with uniform thickness. After shotcrete placement, injection of the specially formulated Preprufe SCS Hydrophilic Grout fills and seals the system, thus providing ultimate waterproofing protection. All components of the specially developed Preprufe SCS System work together to form a continuous and integral bond to the structure, eliminating lateral water migration between the membrane and the shotcrete. When properly installed and grouted, the Preprufe SCS System will protect against water ingression.
