Why Seawalls Fail and How it Can Impact Selling Your Home

by Scott Myers

Seawalls are one of the single most expensive aspects of a waterfront property. The seawall must withstand some of the most brutal conditions of any structure built today. Cracking, bowing, or erosion of the ground behind the wall can be signs of trouble. Heavy loads due to high levels of ground water, violent storms, and marine borers are just a few of the hazards to consider when evaluating a seawall. Duncan Seawall has been in business since 1979 and has maintained an excellent reputation for always being honest with our customers.

Erosion hole behind wall caused by soil slowly seeping through the seams between the seawall panels. There is no evidence of cracking in the seawall cap or seawall panels. This can typically be repaired by excavating the soil behind the wall, installing filter cloth over the seawall seam and back filing with crushed shell. Typical cost for an erosion hole repair is approximately $500.00.
