Скачать или смотреть The Urethane Grouting Process

Urethane grouting allows us to fill voids and raise slabs. The key is in the prep work. Based on the percentage of accelerator used, the ambient air temperature and temperature of the grout mix, and the level of moisture within the soils or concrete being grouted, the set time which the grout begins expansion can be adjusted (from 30 seconds to 5 minutes). That “time to expand” provides the ability of the grout to flow a large distance in all directions before expansion begins. By delaying expansion we filled voids at different levels and of various sizes. This particular job is in an office building and the urethane grout was used to fill multiple voids that were present several feet below the bottom of the slab, as well as raising the slab several inches.
