Pressure Grouting
Need Ground Improvement Technique You Can Count On? We’re Here to Help.
When weak soils or voids threaten the stability of your structure or site, you need a ground improvement method that’s precise, proven, and adaptable. That’s where we come in.
As experienced ground engineering contractors, we specialize in pressure grouting — a versatile technique that strengthens soil and fills voids restoring confidence and stability beneath your structure.
So, What Is Pressure Grouting?
Pressure grouting involves injecting grout (a cementitious or chemical mix) into the ground under controlled pressure to fill voids, bind loose soil. The grout hardens in place, improving the strength, density, or impermeability of the ground.
This technique is ideal for stabilizing existing foundations, underpinning structures or preparing poor ground for new construction.
How We Solve Your Problems
✅ Dealing with Weak or Loose Soil?
Pressure grouting improves soil strength and reduces settlement risk — giving you a solid, engineered base for construction or remediation.
✅ Worried About Voids or Sinkholes?
We can precisely target and fill underground voids or cavities — preventing collapse and extending the life of existing structures.
✅ Not Sure What’s Happening Underground?
We’ll conduct thorough ground assessments and recommend the right grouting technique for your site — whether it’s compaction, permeation, or structural injection.
Frequently asked
questions
What types of structures can benefit from pressure grouting services?
Structures like foundations, walls, bridges, tunnels, and dams can benefit from pressure grouting, as it strengthens weak soil, fills voids, and stabilises structural components.
What are the signs that a structure may need pressure grouting?
Signs include visible settlement or cracks in foundations, misaligned doors or windows, and signs of water seepage or voids under floors, which indicate instability.
What are the long-term benefits of using pressure grouting for structural support?
Pressure grouting enhances load-bearing capacity, improves soil stability, reduces future settlement issues, and extends the structure’s lifespan by reinforcing its foundation.
How do you assess the need for pressure grouting in a building?
Assessment includes site inspections, structural evaluations, and geotechnical testing to identify voids, soil weakness, and any signs of structural movement or instability.
What is the typical timeline for completing a pressure grouting project?
Timelines vary by project size but typically range from a few days to a week for standard grouting projects, allowing for rapid stabilisation.
Are there any potential risks or challenges associated with pressure grouting?
Risks include potential over-pressurisation that could cause cracking or displacement, which is mitigated by careful monitoring and experienced application techniques
How can your engineers assist in determining the suitability of pressure grouting for my project?
Our engineers conduct a thorough site assessment, analyse soil and structural data, and recommend grouting options suited to your project’s specific conditions and needs.
