Injection into masonry

In the case of injection into masonry the injection material is injected continuously via low pressure packers, which are in offset arrangement in the form of a grid, at low pressure (low pressure process). In this manner the faulty joints as well as the capillaries, pores and hollow cavities in the bricks are filled in with the injection material.

The continuous injection into the masonry is applied in cases when the previous surface sealant, e.g. an older bituminous sealant, has become defective.

Recommended systems

Acrylate gel

  • Viscosity is comparable with the one of water. Thus hair cracks can be grouted successfully
  • Adjustable swelling ability
  • High mechanical strength
  • No risk of corrosion on the reinforcement


Rubber-elastic, 3 C acrylate gel, multi purpose applicable

  • Very low viscous acrylate gel
  • Very good penetration
  • Proven stability of at least 16 years


Adjustable, low viscous rigid acrylate resin with high final strength.

  • Low viscous
  • Very good penetration
  • High final strength


Adjustable, low viscous, quickly reacting 3 C acrylate gel

  • quickly reacting

Polyurethane resin

  • Penetrates even into haircracks
  • Flexible hence good movement assimilation


2-component injection resin based on polyurethane

  • Officially approved system
  • Proven against water pressure of 7 bars
  • Approved for use in CHF and LMSS plants


2-component high flexible injection resin based on polyurethane

  • Universal and economical
  • highly flexible < -35°C


Slowly curing, from ridged to tough elastic, 2K polyurethane resin, which foams up in contact with waterPUR-O-STOP FS-L

  • Stabilizing and sealing of masonry
  • Adjustable pot life (90 min – 58 sec.)
  • Groundwater friendly approved

Injection cement / Injection mortar

  • For subsequent injection in non-full face mortared bed joints
  • Injection into masonry
  • No addition of thickeners required


Single-component injection material based on extra-fine cement

  • Very high compressive-strength
  • For injection in cracks above 0.2 mm

Pressureless injection

  • Usable at 95% of penetration of dampness
  • Solvent-free
  • Ready to use


creamy like injection material against uprising humidity (horizontal barrier)
