PUR-O-Stop FS-L

PUR-O-STOP FS-L is a slow-hardening, rigid, two-component injection resin based on polyurethane for water proofing and stabilization of water bearing structures. PUR-O-STOP FS-L is an injection resin with variable reaction time which can be adjusted by adding the catalyst (see pot-life table). PUR-O-STOP FS-L penetrates well into structures to be sealed. Upcoming water gets mostly forced out due to the viscous and hydrophobic mixture. At borders of resin/water the mixture develops stable and solid foam. PUR-O-STOP FS-L has a German General Building Inspectorate Approval as an injection product for curtain grouting. PUR-O-STOP FS-L is used for stabilisation and solidification of water bearing rocks, ground, sand as well as for stopping in rushing water in tunnels, shafts, dams and other building structures made from concrete or brickwork and as a concrete injection product for force transmitting filling of cracks.
