A swallow hole appeared beneath the patio area of a domestic bungalow, which undermined the existing foundations. The hole was grouted and then the foundations of the bungalow underpinned to prevent any future settlements.
Piles and reinforced concrete needle beams were installed and constructed beneath the original shallow foundations of a porch extension, which had been constructed on ‘soft’ made ground. The new piled underpinning foundation takes the load of the structure down to suitable bearing strata.
A bungalow suffered subsidence due to localised softening of the bearing strata due to damaged and leaking drainage. Piles and reinforce concrete needle beams were installed externally to the property to prevent further settlement of the structure.
