Koster G4 Gel – Low viscosity Acrylic Gel for Curtain Injection and Injection into Masonry and Concrete

Koster G4 Gel is a water based, elastic acrylic gel with a very low starting viscosity after initial mixing. It is capable to bind water during the gelation. The swelling ability after full curing allows a 40% intake of additional water into the gel structure. Due to the low starting viscosity it can be injected into fine substrate pores.

Fields of Application

For waterproofing below ground construction elements on the outside by curtain injection. For injection into full brick masonry in order to seal the mortar joints against water ingress. Can be applied in special waterproofing applications such as tunnels, shafts, voids, cracks, and concrete injection according to the EN 1504 as well as for soil stabilization.

Consumption

Depends on the field of application.

The consumption stated always refers to the ready mixed and already diluted product. Minimum Consumption (reference values):

• Curtain Injection: min. 40 kg / m² (standard 50 kg / m²)
• Injection into masonry: 4 kg / m² for every 10 cm of the brick wall thickness
• Horizontal Barrier (DPC) Approx. 2.4 kg / m for every 10 cm of the brick wall thickness
