PUR-X 100

Download PUR X 100 Data Sheet

Designed for

  • 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.

Benefits

  • PUR-X 100 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.*

PUR-X 200

Designed for

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

Benefits

  • PUR-X 200 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.

PUR-X 300

Download PUR X 300 Data Sheet

Designed for

  • Sealing dry, moving, nonstructural 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.

Benefits

  •    PUR-X 300 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.

PUR-X Soil

Designed for

  • Soil strengthening
  • Soil coagulation
  • Soil stabilisation
  • Fixing of ground anchors
  • Probe grouting
  • Curtain grouting

Benefits

  • Single component, easy application.
  • Very low viscosity for easy soil penetration.
  • Very long reaction times that can be varied to suit by adjusting the amount of catalyst.
  • Environmentally friendly product.
  • High mechanical and chemical resistance of the cured polyurethane.

ACRYL-X

ACRYL-X 1000 is a non-toxic aqueous solution of multifunctional acrylic monomers. The resin gels in a few seconds to a few minutes when an activator/initiator is added just before use. The final product is a soft and tacky crosslinked gel. In wet, or dry conditions, the volume of the gel increases, or decreases, in a reversible and waterproofing manner.

Designed for

  • Below grade expansion joints with reinforcement agent instead of water in the B-component.
  • Screen Injections.
  • Injection into very fine leaking cracks or joints.
  • Injection of Re-Injectable injection hoses.

Benefits

  • Multipurpose product.
  • Very good adhesion to many substrates.
  • Non-toxic.
  • Not flammable.
  • No acrylamide.
  • Very low viscosity.
  • Durable in wet and dry conditions.
  • Wet-dry cycle behaviour can be improved by adding special agents.

Designed for

  • 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.

Benefits

  • ACRYL-X 2000 forms a flexible gasket or flexible plug in the joint or crack into which it has been injected to prevent further Water infiltration.
  • ACRYL-X 2000 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 microorganisms.*
