ELCOROCK®

Sand filled geocontainers for coastal erosion protection

ELCOROCK® is a specialist geotextile sand container that has seen an increasing use in hydraulic applications over the past decade, especially as a replacement to hard rock armour systems.The flexibility, versatility and proven performance makes ELCOROCK®  a cost effective alternative to "hard rock" solutions for sea walls and revetments as well as for the construction of groynes and breakwater structures.

ELCOROCK® is also extremely user friendly, adds to local amenity and reduces the potential for injury and public liability. The flexibility of an ELCOROCK® structure allows enhanced environmental amenity, through focussed planting or integration with the surrounding environment.

Properties

ELCOROCK® containers are manufactured from specifically manufactured non-woven, needle-punched, UV-stabilised staple fibre geotextile. The sewn seams of ELCOROCK® containers are uniquely configured to maximise the mechanical characteristics required to meet the long term durability requirement for exposed coastal sites.

Application

ELCOROCK® containers are supplied to site flat packed for ease of transport. Specialist filling equipment is used to ensure that the maximum mass and volume can be achieved for each container. Geofabrics can also supply J-bins for placement of the containers into position. This system of using local sand fill offers flexibility of design and a robust solution in coastal, river or other dynamic applications where environmental impact must be minimised. The high level of research conducted and the long-term performance of existing ELCOROCK® structures ensures detailed design can be performed, including structural stability in aggressive wave conditions.
