AW-TG Method

The AW-TG Method (Anti-Washout Thixotropic Grout Method) is a grouting technique developed to overcome the limitations of conventional grout methods, particularly the dilution or dispersion that occurs when grout encounters strong flowing groundwater. It provides excellent anti-washout performance and water resistance. The grout can be selectively injected even under underwater conditions without dilution or material loss. It features a short gel time and maintains a plastic state—a condition without self-flow but capable of flowing under small pressure—for several minutes, allowing the grout to fill voids densely and completely as a backfilling material.

LW Method

Gel breaks without a plastic state during injection and immediately disperses and dilutes in water.

When the upper part of the liquid is stirred and flow occurs, the gel easily breaks down and the water becomes cloudy.
AW-TG Method

The gel is injected in a plastic state. It does not disperse or dilute in water.

Even when flow occurs, the gel does not break down at all and the liquid remains clear.
