Mini and Micro Piling

Where access is restricted or heavy plant used for conventional deep foundation systems is prohibited, foundations may be constructed and strengthened using mini piles which provide an alternative to traditional methods with minimal vibration and noise pollution. Mini piles generally have a diameter between 100 and 400mm and can be constructed with reinforcing cages, circular hollow sections or grouted with a centralised bar achieving high compressive and tensile working loads. 

Mini Piles can be used in most types of soils and typical applications in confined spaces, noise and vibration restricted areas include; Construction of high capacity small diameter piles, underpinning or strengthening of existing structures, upgrading of existing floor slabs resisting hydrostatic up-lift pressures, slope stabilisation works, construction of shored or un-shored retaining walls and upgrading of existing bridges for road/rail abutments & piers. 

The team at Geovert have installed various types of mini piles with significant amounts constructed in confined spaces in the rail corridor, where safety has been an underlying factor, including retaining walls and the underpinning and strengthening of pylons and bridge abutments.
