Underpinning Jacks are fully adjustable and are used to support the weight of existing structures in underpinning applications. The height of the jack is adjusted by way of the nut to suit the correct height required to support the structure above, whilst works are carried out to the foundations.

They are manufactured from heavy duty components consisting of steel studding, a large nut, tubing and top and bottom support plates.
