Concrete Block Revetment — Seawall Face Protection

What is Concrete Block Revetment?

KCC installs and reinstates concrete block revetment systems on seawall faces and coastal embankments, providing durable protection against wave action and erosion. Works include removal of displaced or damaged blocks, preparation of the underlying layer, and placement of new blocks to the design profile.

What's Included

Survey of existing revetment condition and identification of displaced or damaged blocks
Removal of displaced blocks and preparation of underlying filter layer
Placement of new concrete blocks to design profile by crane from barge
Diver inspection and adjustment to confirm correct placement and interlocking
Post-works survey to confirm profile and coverage

Why This Matters

Displaced or damaged revetment blocks leave the underlying structure exposed to wave attack and erosion. Timely reinstatement of revetment systems prevents progressive deterioration and protects the structural integrity of seawalls and coastal embankments.
