As tidal flows rise and fall, water pushes its way in through cracks, joints, and defects in seawalls and bulkheads. The water pushes in on incoming tides and flows out on outgoing tides. As the water flows out, it carries sand and soil with it which causes undermining of the structure, voids to form, and deteriorates the structural integrity of the seawall. This cycle is exacerbated during periods of heavy rain which continue the outflow of soil. Fortunately, defects in the soil surrounding seawalls and bulkheads can be repaired with high-strength polyurethane grouts, cracked wall caps can be repaired with high-strength epoxy, hydrostatic pressure control filters can be installed/replaced to ease the strain, and if necessary an advanced permanent anchoring system can be installed to prevent future damage to high-risk sections of the wall.
