Various factors influencing the major properties of water soluble polyurethane grouting materials arestudied by properties tests.

The properties of grouting materials used in the curtain grouting with hole-top enclosure of the Jiangya Project are studied under normal and high pressures through the laboratory grouting testing.

However, many methods and groutingmaterials to deal with the cut slope are maintain in low level yet, lack of highlyfunctional and environmental protecting grouting materials, it would be a barrier ofthe highway develop.
