Demak prepares semipermeable wave breakers for coastal protection
Workers are preparing Hex-Brick wave breakers on the coast of Timbulsloko village in Demak, Central Java.
The blocks will form a semipermeable structure designed to reduce the impact of waves.
The work is part of efforts to protect Java’s north coast from coastal erosion.
Timbulsloko is also the site of a nature-based protection pilot that includes planting mangroves.
The pilot is linked to preparations for a giant sea wall system planned for Java’s north coast.
Mangrove planting was scheduled to begin on October 19, 2026.
Workers are preparing semipermeable wave-breaker structures on the coast of Timbulsloko village in Demak, Central Java.
The structures use hexagonal blocks called Hex-Brick.
The work is part of preparations to protect the north coast of Java.
The technology is expected to help reduce coastal erosion.
A nature-based coastal protection pilot, including mangrove planting, is scheduled for October 19, 2026.
