Beach RenourishmentUnlike other erosion control approaches,
HEI's erosion control mat works with nature as a constantly replenishing mechanism. Should the mat become unfilled in any way (due to unexpected severe currents), it will refill when normal current velocities are restored.
In over three-dozen field installations, the mats have proven to be an effective and efficient erosion control technique.
Erosion control mats are designed to work with nature in the building of fiber-reinforced underwater berms. Such berms reduce the impact of wave energy, thereby allowing a natural renourishment of beach sand from transported material. The mats provide unintrusive, environmentally friendly erosion control while contributing to natural beach renourishment.
In coastal protection applications, the mats provide two actions; 1)The berm builds up and slows down wave action, diminishing erosion, and 2)The slower wave action slows the sand in the waves and causes it to be deposited on the beach side of the berm--slowly rebuilding the beach.
