Grouting Services has been involved in numerous strengthening projects utilising its' expertise in micro-piling, external post-tensioning and structural strengthening and repair. Consistent with our strategy of continual improvement, we have teamed up with leading organisations to ensure we offer the latest and most appropriate technology for strengthening existing structures.
Mini-Piles
Mini-piles are 300mm or less in diameter and can be designed as soil frictional piles and rock socketed piles either in tension or compression. They typically employ a central tendon or pipe and are grouted in place with high strength cement grout. It is common practice to carry out test piles to verify the capacity and installation technique prior to commencing the production mini-piles. The production mini-piles are generally not tested, but if required, can be economically tested in tension with a simple reaction frame. Compression testing is more complicated and expensive as it requires additional mini-piles (or restraining anchors) to provide the necessary reaction.
Grouting Services has developed, engineered and tested a new mini-piling system suitable for use in seismic strengthening and uplift applications. The "G-Pile" is generally a tension / uplift pile although some compression capacity is possible with the use of external confinement. Numerous projects have been completed involving both tension and compression mini-piles all designed and constructed by Grouting Services.
External Post-Tensioning
Grouting Services has completed numerous projects including bridge strengthening and building retrofit works.
Structural Strengthening and Repair
It is imperative that the substrate is suitably and adequately prepared prior to the introduction of any strengthening or repair products.
