You may have read our post on stabilizing seawalls a few months ago. But what about raising them?
As ocean levels begin to rise due to global warming, it will become more common to raise seawalls to help combat flooding during high tides.
Seawalls help prevent erosion of land area or damage to structures by placing a barrier between the sea and land. This helps prevent damage to structures from wind, wave and tidal forces. Typically, seawalls are curved or flat-facing, and can be built using gravity retaining walls, cantilever retaining walls, and pile-supported retaining walls. Seawalls are usually constructed of concrete, but in the past stone was used due to its durability. Stone is also used as rip-rap in front of seawalls to prevent or minimize scour as well as reducing wave energy. Continue reading
