BULKHEAD SEAWALLRETAINING WALL / BULKHEAD OR SEAWALL TILTED / CRACKED / DETERIORATED / AMISS: A retaining wall is constructed to contain a lateral force, such as a bank of dirt. Bulkheads (seawalls) are designed to hold back the damaging action caused by water, whether ocean, lake or river water When the lateral force exceeds the structural ability of a retaining wall to contain it, the wall will crack, bulge, tilt or fall. These problems are often caused by excessive moisture not being relieved through weep holes in the retaining wall. Often tree roots or insufficient structural strength for the particular load lead to eventual failure When a retaining wall is tilted more than three percent out of plumb it may be in danger of falling. Three percent means about 2 1/4 inches for a six foot tall wall for additional information Generally retaining walls cannot be repaired once they have shifted However proper drainage may slow or stop further damage Be sure weep holes are clear. Don't oversaturate the soil behind the wall Provide a swale (a dirt trough/ditch) to run water away from the area immediately above and behind the wall Bulkheads can be damaged by water action, especially during severe weather. It is important to keep the bulkhead in good condition since even the smallest breach can lead to rapid failure. It is recommended that a qualified seawall specialist review the wall at regular intervals to assure its condition If replacement of the wall is called for it should be built by a qualified licensed Contractor who specializes in retaining walls and/or bulkheads.
