Anti-Washout Thixotropic Grout Method
AW-TG Method
The AW-TG Method (Anti-Washout Thixotropic Grout Method) is a grouting technique developed to overcome the limitations of conventional methods, particularly dilution and dispersion under flowing groundwater conditions. It provides excellent anti-washout performance and water resistance, enabling controlled injection even under underwater conditions without material loss. The grout features a rapid gel time and maintains a plastic state—having no self-flow but capable of flowing under low pressure—for several minutes. This behavior allows dense and complete void filling, ensuring reliable backfilling performance.
-
LW Method
Gel breaks without forming a plastic state and rapidly disperses and dilutes.
When flow is induced, the gel easily disintegrates, causing turbidity in the water.
-
AW-TG Method
The grout is injected in a stable plastic state and does not disperse or dilute in water.
Even under flowing conditions, the grout maintains its integrity and the surrounding water remains clear.
