All You Need To Know About Revetment Wall

Rock revetments may be used to control erosion by armoring the dune face. They dissipate the energy of storm waves and prevent further recession of the backshore if well designed and maintained. 

A rock revetment wall is a way of absorbing the energy coming from incoming waves and water. Revetment prevents and lessens the damages of coastal erosion. Revetments are sloping structures comprised of various layers of large stone and geotextiles placed on banks and shorelines used to prevent shoreline loss.

Revetment walls are permanent structures designed to prevent shoreline erosion. By definition, a revetment is a protective covering on an embankment of earth designed to maintain the slope or to protect it from erosion.

Rock revetment construction should not be done without expertise from a coastal consultant and marine construction contractors. Rock structures on the shoreline should be designed with careful consideration for the rock size, face slopes, crest elevation, and crest width.

The size of rock used depends on factors of waves such as height, direction, slope, cross-sectional design, and availability of the armour rock.

Revetment costs are mainly dependent on the dimensions and material used. Some constructions can provide an unlimited life expectancy while other, smaller-scale rip-rap slopes will need regular maintenance. Like anything in construction, you’ll get what you pay for.
