Are interlocks waterproof?
The interlocks of hot-rolled sheet piling are fairly water tight, but not waterproof. Sheet piling is used as cut-off walls under hydraulic structures such as locks & dams. It is also utilized for cut-off walls at hazardous waste sites. There are products available to seal the interlock and reduce or eliminate seepage through the interlocks. Contact the member companies for additional information on interlocks and sealant products.
