Extending land into water often presents geotechnical challenges due to soft and muddy soil conditions. Leca LWA effectively addresses these issues by compensating and reducing the load on confining structures.

Leca LWA is well-suited for use in quay and land extension designs, including sheet piles, sheet pile cells, and caisson structures. It is also ideal as a fill replacement in solid berth structures, particularly when quayside waters are dredged to greater depths.

With its extremely low unit weight and minimal buoyancy, Leca LWA is especially suitable for direct filling into water, ensuring stability and efficiency in such projects.
