Polyurethane Injection Resins

Polyurethane injection resins from Prime Resins are optimally formulated to stop leaks, lift slabs, stabilise soils, fill voids, and protect concrete structures.

  PRODUCT DESCRIPTION TDS BROCHURE
  Prime Flex 900 XLV Prime Flex 900 XLV is a low viscosity, hydrophilic polyurethane resin that reacts with water and expands to form a closed cell, tough watertight flexible foam. It is typically injected under pressure to seal actively leaking joints and cracks in concrete structures, including hairline cracks. It can be used with jute fibre (oakum) to seal wide gaps, cracks and defects.
  Prime Flex 900 MV Prime Flex 900 MV is a medium viscosity, single-component polyurethane resin that reacts with water and expands to form a closed cell, tough, watertight flexible foam. This hydrophilic grout is typically injected under pressure to seal actively leaking joints, cracks, pipe penetrations and expansion joints in concrete structures. Its viscosity makes it a good choice for medium to wide cracks or joints.
  Prime Flex Hydro Gel SX Prime Flex Hydro Gel SX is a versatile, easy-to-use single-component, water-activated, low-viscosity hydrophilic polyurethane injection resin for sealing actively leaking joints and cracks in underground concrete structures. It forms either a closed cell, watertight foam or impermeable gel depending on the water to resin mix ratio. Cured material remains flexible and has excellent adhesion. Ideal for manholes. It can also be used for soil binding for slough control.
  Prime Flex 910 Prime Flex 910 is a single-component polyurethane used for soil stabilisation and void filling. It is a hydrophobic, super low viscosity, water-activated polyurethane with variable set time that forms a rock hard, watertight mass. Requires catalyst.
  Prime Flex 920 Prime Flex 920 is a single-component polyurethane used for void filling, curtain grouting, and sealing high-flow gushing leaks, including wide gaps and cracks in structures not subject to movement. It is a hydrophobic, low viscosity, water-activated polyurethane with variable set time that forms a rigid, rock hard, watertight mass. Requires catalyst.
  Prime Kat (Catalyst for 910 & 920) Prime Kat is our proprietary catalyst used to adjust the reaction time of Prime Resins’ hydrophobic polyurethane injection resins, including Prime Flex 910 & 920.
  Kick Fast (Catalyst for 910 & 920) Kick Fast is the catalyst needed when a very fast set time is required when using Prime Resins’ hydrophobic polyurethane injection resins.
  Precision Lift Precision Lift is a hydro insensitive, two-component, high-density polyurethane foam used for void filling, compaction grouting, slab lifting and stabilisation, and undersealing slabs. Several densities are available.
