Seawall life spans on the Pacific Coast of the can vary considerably depending on the original seawall design and the materials utilized during the initial construction. In addition to those two variables, the seawall's exposure to tidal forces and coastal erosion, as well as, damage from lack of maintenance can further contribute to premature seawall failure.
Design lifespans for seawalls are typically in the range of 35-40 years yet many seawall found in the City of Malibu and surrounding coastal communities have already exceeded that. Frequently homeowners don’t realize their seawall needs periodic inspections and ongoing maintenance to achieve it's expected life span. Consequently lacking seawall maintenance is the most common cause of seawall defects and seawall failure encountered during our seawall inspections. Seawall replacement costs can be upwards of $1,000 - $3,000 per linear foot depending on site access, seawall design, and site geology.
OUR SEAWALL INSPECTION PROCESS
Seawall components including but not limited to the seawall cap, bulkhead, seawall panels, footings, and any other seawall components that are visible from the land side of the structure. Ocean side inspection of seawall and bulkhead by walking exterior during low tide is performed when possible, diving is optional and is not considered a mandatory part of a seawall inspection.
Seawall Inspectors Look For:
- Land side components of the seawall system for signs of settlement or soil loss
- Soil / sand behind the seawall
- Foundation supports, caissons, pilings, collars, stringers, joists, and decking
- Construction methods of existing seawall and materials used
- Any visible damage
- All recommended seawall repairs
Seawall Field Report Includes:
- Any evidence of structural deterioration, failure, or inadequacy in the existing seawall and bulkhead
- Photographs corresponding to any deficiensies listed on final seawall report
- Complete list of repairs that are recommended with photos
Seawall Inspector Is Not Required To:
