Classification

It is a dry-mixed material with cement as the basic material, a proper amount of fine aggregate, and a small amount of concrete admixture and other materials. After mixing with water, it has high fluidity, early strength, high strength, and micro-expansion properties.

WJG-433 inorganic salt grouting material

It is a two-component or multi-component homogeneous liquid grouting material made mainly from an aqueous solution of acrylate monomers with an appropriate amount of crosslinking agent, accelerator, initiator, water and/or modifier added.

WJG-434 epoxy resin grouting material

It is a material mainly composed of epoxy resin, with a certain proportion of curing agent, diluent, toughening agent, etc., mixed together.

WJG-435 polyurethane grouting material

WJG-436 silane-modified polyether grouting material

A homogeneous liquid composed primarily of a resin synthesized from the polymerization of silane and polyether polyol, along with mineral fillers and additives. This material is a grouting material that forms an elastomer through reaction with water.

Polyurethane grouting material for emergency rescue in tunnels, subways, and galleries

It is a functional material that can quickly stop water leakage. It utilizes the characteristic of isocyanate groups in polyurethane prepolymers reacting with water to release carbon dioxide. When the sealant is injected into the leaking area, the material reacts rapidly with water to form a solidified body, thereby reducing or stopping water leakage.

Polyurethane grouting fluid for lifting ballastless high-speed rail tracks (WJG-451)

It is a two-component polyurethane grouting material developed by Jianguo Weiye, composed of Component A: polyol-modified diphenylmethane diisocyanate and polymethylene polyphenyl isocyanate, and Component B: polyol.
