Over time, seawalls begin to develop small defects due to fluctuating tides, and thermal expansion and contraction. As water levels rise and fall, a vacuum is created which easily pulls the saturated supporting soils through defects into the body of water – this creates voids, settlement, depressions, sinkholes, and overall instability of the structure. Avanti's injection grouts have been specifically designed to seal these defective areas from further infiltration/exfiltration by creating a watertight barrier, and fill voids that have developed by binding existing soils together preventing further erosion.
