At PSM, we offer substantial expertise in grouting applications, delivering reliable, cost-effective solutions tailored to your project’s specific needs. Whether you're managing complex ground conditions or looking to enhance foundation performance, our team is here to support your success.
Reliable Grouting Solutions
PSM delivers tailored grouting solutions for complex ground conditions, combining extensive experience, laboratory testing, on-site validation to ensure performance and reliability, as well as the ability to develop bespoke solutions for unique problems. Our expertise spans soil improvement and rock grouting techniques, with proven success across infrastructure, tunnelling, and water management projects. Our services include:
- Jet grouting and deep soil mixing: Ground improvement design solutions with validation via targeted sample retrieval and borehole imaging.
- Soil permeation grouting: Design and application of permeation grouting using tube à manchette (TAM) methods to improve soil uniformity and strength.
- Rock grouting: Pre- and during-excavation grouting in jointed rock involves injecting cementitious or chemical grouts into rock fractures to reduce permeability and control groundwater flow. It is commonly used for seepage control, ground improvement, and structural stabilisation.
- Construction supervision and validation: On-site oversight and timely technical support to ensure effective grouting outcomes under changing conditions.
- Specialised grouting applications: Bespoke solutions for tunnel lining support, dam penetrations, canopy tube annulus grouting, and diversion pipe sealing.
PSM brings a rigorous approach to evaluating grouting effectiveness, informed by both laboratory testing and appropriate validation approaches. Our team has conducted detailed laboratory assessments of colloidal silica and ultra fine cement permeation grouts, analysing properties such as viscosity, gel time, and strength, along with the performance of treated soils.
In addition, PSM has provided forensic investigation and engineering advice on projects where ground improvement works did not meet expectations. These investigations have helped define the nature and extent of issues, supported dispute resolution, and guided appropriate remediation strategies—ensuring our clients have the insights needed to move forward with confidence.
