The average lifespan of a seawall ranges from 50 to 60 years, depending on factors such as build quality and location.

Seawalls generally require minimal maintenance as long as any cracking, shifting, or erosion is promptly repaired.

3. What are the openings in seawall panels called?

The openings in seawall panels are referred to as "weep holes." These holes allow water to pass through, relieving pressure from behind the seawall.

Missing soil behind a seawall is often a result of erosion holes, which occur when dirt washes through cracks in an aged or damaged seawall. BlueLadder Builders can typically repair erosion holes if the damage is minimal.

Signs that indicate the need for seawall repair or replacement include significant cracks in the panels or cap, severe erosion, separation of panels, and noticeable leaning of the wall or cap.

9. Will my pool be at risk if it is near the seawall?

In the event of seawall failure, there is a possibility that your pool may be affected if it is within the 2:1 "slide zone." To prevent further damage, it is crucial to address any seawall issues that arise promptly.
