Application, parameters and documents →

Polyurethane

EasyInject

Water-reactive 1K PU resin; stand-alone sealing effectiveness depends on filling and confined expansion.

Stainless steel 2K pump (standard); 1K option with extended reaction time and separate selection
Selection conditions

Water: Water or Polymer option; account for hydration, drying and washout after curing.

Material behaviour: Flexible gel; movement capacity must be selected for the joint and does not follow from specimen elongation.

Application, parameters and documents →

Epoxy

EpoxPower

Rigid crack filling and strengthening repairs after assessing the crack cause and activity.

rigid filling · strengthening repair · rigid sealing

System
Two components A + B
Delivery
1K pump after thoroughly mixing A and B
Selection conditions

Water: Dry cracks; moisture tolerance does not mean application in active flow.

Material behaviour: Rigid filling; do not extend selection to a moving expansion joint.

Application, parameters and documents →

Polyurethane

GeoTrack

Ballast bonding and consolidation of non-cohesive soils; reaction behaviour depends on the presence of water.

ground stabilisation · void filling · controlled lifting · rock mass strengthening · fractured rock sealing

System
Two components A + B
Delivery
2K pump, A : B ratio = 1 : 1 by volume
Selection conditions

Water: The TDS covers dry and wet zones; the influence of water requires a trial.

Material behaviour: Lifting movement is monitored by measurement; there is no universal lift height.

Application, parameters and documents →

Polyurethane

GeoPolymer.55

PU foam for void filling, stabilisation and controlled structural lifting.

ground stabilisation · void filling · controlled lifting · sewer joint sealing · water barrier in soil
