What is a VIP-Weco NO DIG Repair System?
VIP-Weco use WRAS approved material, comply fully with BS6920 and have a typical life expectancy of 100+ years.
During the installation process, rubber sleeves and a rubber lining made of EPDM or NBR coupounds are applied over the damaged are of the inner wall of the pipe. Stainless steel sheeting is then placed over the sleeve and lining. This is then held in place by stainless steel retaining bands allowing up to 20 bar of internal or up to 2.0 bar of external pressure.
Once the VIP-Weco is installed, a safe, durable and low-cost mechanical sealing solutions is achieved. Typical installation time of circa 40 minutes per seal.
For special applications such as longitudinal cracking or where aggressive chemicals are used, we develop bespoke sealing solutions
