Excessive post construction and differential settlements constitute engineering challenges for structure founded on soft cohesive soil which caused instability and crack to the existing structure. Inadequacy of design for foundation supporting structure during the early stage of construction and less information on site investigation might be the main reason for this problem. Polyurethane (PU) injection pile is proposed to replace the conventional underpinning pile. No excavation is required and only a small diameter of hole is drilled on the existing slab foundation before injection of PU. An...
