Chemical Injection Resins

Our company offers a complete line of chemical injection grouts to ensure your projects needs are covered.Safety and environmentally friendly products are always a top priority.

Polyurethane

Low viscosity, high elongation, hydrophobic injection resin with superior sealing

characteristics

Not subject to shrinkage due to wet,dry cycles

Pumped as a single component

Can expand more than 20 times initial volume

Low viscosity allows injection into hairlinecracks

Langwei-Seal

Low viscosity, hydrophilic injection resin for filling leaking joints and cracks in concrete, as well as large voids in gravel layers and rock fissures

Hydrophillic - “seeks” water deep into wet cracks

Can be pumped as a single component, or as a two component system with water

Excellent tensile and adhesion properties

Can expand more than 25 times initial volume

Langwei-Cut

Rigid, durable, hydrophobic injection resin for filling leaking joints and cracks in concrete, as well as large voids in gravel layers and rock fissures

Not subject to shrinkage due to wet,dry cycles

Pumped as a single component

Can expand more than 25 times initial volume

Acrylate

Low viscosity, high elongation, hydrophilic acrylate injection resin with superior sealing

Characteristics

Excellent penetration into various substrates & soil

Adjustable curing times

Environmentally friendly

Waterproof, stabilize soil & fill voids

Can be injected against water pressure

Expansion up to 50%

Can be injected in low temperatures

Creation of grout curtains

Soil stabilization behind brick and concrete structures above and below grade

Acrylate grout penetrates deep into soil and solidifies

the substrate.Adjustable curing times mean you have much better control over depth of penetration.
