Product Designed for Benefits
HA Cut
- Tech Data Sheet #1
- Tech Data Sheet #2
- Tech Data Sheet #3

Gushing water - high flow rate and/or high pressure.
Diaphragm walls.
Filling large voids.
Tunnel construction.
Pre-injections in front of TBMs, and NATMs under wet conditions.
Combi-grouting.
Chemical containment via curtain injection under wet or dry conditions.
Soil stabilisation.

  • HA Cut forms a rigid gasket with high strength in the joint or crack.
  • Non-flammable, solvent free.
  • User friendly: 1 component material.
  • Controllable reaction times: by using catalyst curing times can be reduced.
  • Cured compound is resistant to most organic solvents, mild acids, alkalis and micro organisms.*
HA Safefoam
- Tech Data Sheet #1

Grouting joints or leaks in concrete structures.
Sewer joint repair.
Tunnel segment curtain injections.
Moving and non-moving joints.

  • HA Safefoam is a hydrophilic, MDI based resin which is both environmentally safe and user friendly.
  • High expansion rates.
  • Can be used as a 1 or 2-component system.
  • Controllable reaction times: by using    catalyst, curing times can be reduced.
HA Sealfoam
- Tech Data Sheet #1

Sealing dry, moving, non-structural cracks/leaks as a 2-component system with a 1/1 ratio with water.
Sealing moist, moving non-structural cracks/leaks as a 1-compo­nent system.
Sealing leaking joints of concrete tunnel segments
Tunnel segment curtain injections
Honeycombs below ground water level.
Waterproofing accessible sewer pipes.
Expansion joints in combination with oakum or open cell foams.

  • HA Sealfoam is a single component, low viscosity, hydrophilic, polyurethane resin.
  • After curing the resin, forms an inert, flexible, closed cell foam with very good tensile and adhesion properties.
HA Flex SLV
- Tech Data Sheet #1

Grouting joints or stopping water leaks in concrete structures which are subject to movement or settlement.
Specifically developed for injection of fine and ultra fine cracks and construction joints (smaller than 0,5mm).
Stopping water leaks thought the joints between tunnel segments.
Tunnel segment curtain injections
Injection of the LPDE or HDPE membrane in tunnel constructions.

  • HA Flex SLV forms a flexible gasket or flexible plug in the joint or crack into which it has been injected to prevent further water infiltration.
  • HA Flex SLV penetrates fast, expelling the water and can be applied without the need to stop the seepage of leaks prior to injection.
  • Non-flammable, solvent free.
  • Choice of different expansion rates.
  • User friendly: 1-component product.
  • Controllable reaction times: by using catalyst curing times can be reduced.
  • Cured compound is resistant to most organic solvents, mild acids, alkalis and micro-organisms.*
