Pressure grouting is a generic term used to describe a grouting operation, and can refer to several specific applications. Slabjacking utilizes a pressurized grout to lift concrete and is sometimes referred to as pressure grouting.
Hydraulically pumped grouts can provide crucial support for remote places. Large subsurface voids can be a major liability for those above. Even minor voids can cause distress to existing structures, especially those with erosion or flooding problems. Sliplining of buried utilities involves inserting a smaller pipe into the existing one. The annulus between the two pipes can be pressure grouted to secure the system.
