The DRS Drain Pipe Rehab System has been rigorously tested to ensure that it exceeds industry standards. Our product surpasses the tensile, flexural, and compression requirements of the ASTM F1743 and F1216 international standards as well as the same for the BNQ (Bureau de Normalisation du Québec) 1809-400/2013 standard. These results are based on third party laboratory tests using our DRS-W90 Resin and our DRS E-fiberglass.
We take quality control very seriously. We encourage all our installers to read the following article at the link below:
