Spetec High Foamer: Spetec Resin 5 Gallon


  • Single component.
  • Different reaction times are possible by adjusting the percentage of SPETEC® Gen Acc accelerator. To get an even faster reaction, there is also a SPETEC® Gen Acc Fast accelerator available.
  • Cured polyurethane is rigid and exhibits high strength and good chemical resistance. (contact our technical service department for more information)
  • Cured polyurethane is harmless for the environment and resistant to biological attack.
  • Water cut-off of large flow and high pressure water leaks.
  • Sealing foundations and sludge walls, sheet piles, secant pile walls.
  • Stabilisation and water cut-off of large cracks, voids and gravel layers.
  • Pre and post injections in mines, tunnels, pipe jacking, drill & blast and TBM applications.
  • Injections in combination with cement-based grout.
  • Crack and gravel nests injections in concrete structures.
  • Water cut-off of sewer water leaks and sewer stabilisation.
  • Injection of man holes.

Spetec High Foamer: Spetec Resin 5 Gallon

Spetec High Foamer One component, closed cell, hydrophobic, water reactive, phthalate free, low viscosity polyurethane injection resin for cut-off of large water leaks and void filling. In contact with water the SPETEC® STOP HF300 (Highfoamer) will react fast and expand drastically.Questions? Contact us

For leaking joints, check how the joint runs into the construction. Injection holes have to be drilled into the joint. For leaking cracks, drill the injection holes in a zig-zag pattern around the crack to make sure that the injection hole intersects with the crack.


Drill and drill bits of appropriate diameter and length Packers of appropriate diameter and length
Injection pump; manual, pneumatic or electric.


Drill under an angle of 45° into the crack or joint. Ideally the injection hole should intersect the joint or crack about half way the thickness of the wall or slab.
Blow the dust out of the injection hole.

Fix a packer of the right diameter into the injection hole.


Read the technical and safety data sheets prior to commencement of the injection works.
Vigorously shake the SPETEC® Gen Acc, SPETEC® Gen Acc Fast before use. Pour the required amount (5-10%) into the SPETEC® STOP HF300 (Highfoamer) resin.

Mix the accelerator homogeneously into the resin and protect against moisture and rain to prevent premature reaction.
Only prepare that amount of product that can be processed in one day.


Depending on the application, injection can be carried out using a hand pump, pneumatic pump or electric pump.
Preferably use a separate pump for injection of water and poly- urethane resin.

Check if the pump is working properly.
Prior to injection, the pump must be flushed with SPETEC® PUMP CLEANER and be completely free of water to prevent pump blockage.


Start the injection of Spetec High Foamer at the first packer; for vertical joints or cracks this is usually the lowest packer.
Do not over pressurise while injecting; the correct injection pressure is the pressure that allows to resin to flow into the crack or joint. Avoid injecting at pressures of more than 100 bars.

If unreacted resin comes out of the joint or crack, stop the injection and move on to the next packer.
After the last injection of resin into the packer, shoot a little bit of water into the packer in order to make sure that the last injected resin will react as well.


After injection, remove the packers from the concrete and fill the holes with a fast setting cement or any other appropriate filler material.
