Waterloo Barrier - Hydraulic Testing Services

The concept of driving steel sheet piling and sealing joints between adjacent piles was thus introduced. After a series of successful experimental cells, the potential utilization of Waterloo Barrier® in real site conditions was confirmed with approximately one year of prototype field testing. UW and Samuel Roll Form Group then collaborated to develop sheet piling in which a sealable cavity was incorporated into the pile interlock in the manufacturing process. A roll-formed shape was produced and made available for field trials in 1991. Extensive field scale tests were conducted by UW, and bulk hydraulic conductivity values of less than 10^-8 cm/sec were achieved. Installations of a commercial nature are currently in service.
