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