PRODUCT INFORMATION

WEBAC 151

VERSATILE POLYURETHANE INJECTION GROUT  FOR WATER-CUT-OFF  & SOIL STABILIZATION  TYPE OF MATERIAL WEBAC 151 is a hydrophobic water cut-off polyurethane injection grout based on a MDI polyurethane. The resin is 100% solvent free and 100% solids. The gel-time of the product is adjustable by adding a certain percentage of WEBAC 15x accelerator. Upon contact with water WEBAC 151 reacts to a foam while expanding its volume up to 30 times. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell. Depending on the amount of accelerator added and the pressure of injection, WEBAC 151 reacts to a very dense, closed cell, semi rigid material or an open cell, more flexible product. WEBAC 151 is approved for drinking water contact.  RANGE OF APPLICATION  Waterstop for infiltrating water through: - Defective Concrete (Cracked or Honeycombed) - Concrete Joints - Limestone - Brick Construction - Pipe Intrusions - Waste Water Tanks - Drinking Water Reservoirs - Sewers, Manholes, Utility Boxes, etc. - Tunnels, Dams - Soil Stabilization WEBAC 151 is extremely well suited for the filling of large cavernous spaces and cracks in stone or concrete structures as well as for cutting off gushing water of high pressure and speed. Due to the low viscosity of the material, WEBAC 151 offers superior penetration in hairline crack injection.  WEBAC 151 is a product of the WEBAC polyurethane injection resin line and to achieve best results a combination of several products may be recommended in some applications.  WEBAC 151 is a non-shrink soil stabilization grout. The moisture content of the soil must be sufficient to ensure reaction. PROCESSING WEBAC 151 and the Accelerator WEBAC 15x (151/157 B) are supplied separately to allow adjustment of gel-time and to provide a long shelf life.  A mixing ratio between 50:1 and 10:1 (A:B, 2% -10% accelerator) is recommended.  In critical high pressure water-intrusions, the system will react aggressively on contact with water when catalyzed at 10%. A slightly catalyzed product at 2% on the other hand assures good penetration results in very fine capillary crack injection. For extremely short gel times WEBAC 151Bs is available. The accelerator system has been proven far superior to the solvent-loaded single component materials. The WEBAC system gives the applicator the choice to control gel-time and reactive properties. Observe temperature and humidity of the environment, since both determine the pot-life of the premixed batch. Do not mix more material than the amount that will be pumped within reasonable time. Rule: High temperatures and high humidity - less accelerator. Since WEBAC 151 reacts with the moisture in the structure, single component injection equipment is recommended. Hydrophobic grouts do not need large amounts of water for the reaction unlike hydrophilic materials. Simultaneous injection of water is not necessary. If the area of application seems to be dry, pre-injection of water is recommended. It is essential for all equipment to be dry. Avoid any moisture contact with the mixture to prevent premature reaction of the product. If reaction of the batch occurs while pumping, immediately shut down the machine and flush with a cleaner to avoid built up and clogging of the equipment. WEBAC 151 and WEBAC 157 may be mixed.  MAINTENANCE OF EQUIPMENT Remove all excess sealant and any smears. Tools and mixing equipment are best cleaned immediately after use. WEBAC provides R70 Pump Flush, a solvent free, non-flammable, non-hazardous cleaner.  Xylol, Toluol, Acetone and M.E.K. can be used if not in conflict with regulations on jobsite. WEBAC does not recommend the use of hazardous cleaners. Circulate cleaner through pump for several minutes. Caution! Some cleaners are combustible. PRECAUTION Protect your health! WEBAC 151 is 100% solids (does not conatin any solvents) and is TDI free. Nevertheless, while working with WEBAC materials safety goggles, gloves and safety clothing must be worn at all times. While injecting, a full face shield is strongly recommended. Spills and packer blow-outs do happen! Also observe container labels, MSDS, and instructions in the WEBAC Product Catalog. In case one of the components comes in contact with the skin, wash thoroughly with soap and water. Provide adequate ventilation in volume and pattern in working area. Further protection: emergency showers and eyewash stations. TECHNICAL DATA Please refer to pdf file WEBAC 151
