Acrylic-based gel injection system
An acrylic-based gel injection system designed for ground improvement, water-stopping curtain grouting and structural crack filling. Thanks to its low viscosity, it easily penetrates fine cracks and pores. After gelling, it retains its flexible structure and accommodates building movement.

It is used in applications such as ground injection, water-stopping curtain grouting, waterproofing of tunnel and metro structures, basement crack injection and rock consolidation.
The time is set by the G202 initiator dose: 0.15% ≈ 11 minutes (deep spread in hairline cracks), 0.50% ≈ 3.5 minutes (standard crack injection), 1.0% ≈ 1.7 minutes (medium-flow leak), 2.0% ≈ 1 minute (high-flow leak), 4.0% ≈ 35 seconds (pressurised active leak). The G201 accelerator is used at 5% – 10% on the resin side. The reaction speeds up as the temperature rises; always run a trial mix in a plastic cup on site first.
Acrylic gel injection has a lower viscosity than polyurethane injection and can penetrate finer cracks. The gel swells as it absorbs water; when the water level drops it releases some of it, but its high water-retention capacity means it does not crack easily. Its capacity to form water-stopping curtains is higher.
