Sanipor Joint Sealing Technique Gets WRc Approved Certification
The Sanipor process has been used within the UK for over 17 years for renovating sewers, laterals and manholes. It is quite a simple process and comprises the application of two specifically designed silicate-based chemical compounds. These are pumped in turn into the sewer to be renovated and interact to form a sealing gel/compound within any pipe defect and in the soils surrounding the pipe defect.
In September 2006 the Sanipor flood grouting system gained WRc Approved™ status. Commenting on the approval achievement of the Sanipor process Dave Buxcey, Sanipor Projects Manager for Laing O’Rourke said: “The granting of ‘WRc Approved™’, by such an internationally well-respected independent body, not only confirms the Sanipor process to be fit for purpose but also, following a stringent Environmental Impact Assessment, that it is truly environmentally friendly.”
For WRc, Andy Russell, Consultant Engineer WRc Utilities said of the Sanipor testing programme: “The award of a WRc Approved™ certificate is the culmination of a rigorous programme which included auditing the Sanipor installation manual, including two site visits to witness its application; an environmental impact assessment of the constituent Sanipor chemicals and long-term hydrostatic testing. This achievement is testament to the Sanipor system and the effort that Laing O’Rourke has made.”
