Boost Shoreline Protection with the Construction of a Revetment

25 May 2022

People living or working near the coastline can conveniently enjoy the magnificent view of the surroundings. And with these views, they can easily gain health benefits and life improvements. Property owners, however, must ensure that their buildings or structures are protected from coastal erosion.

Coastal erosion is the displacement of some land areas due to waves, currents, and tides. It can likewise happen due to waterborne ice, heavy storm impacts, and others.

The impact of coastal erosion can be significant, especially for those living or working near the coastline. As some parts of the land are displaced, a wide array of homes, roads, and structures can be destroyed. Fortunately, revetments can be maximised to prevent the drastic effects of coastal erosion.

An Overview of Revetments

Revetments are solid structures that are constructed along seawalls and bulkheads, protecting them from constant exposure to aggressive waves and water. Once these structures have been constructed, they can prevent water elements from damaging coastal properties. They can likewise prevent the movement of large amounts of soil. Revetments are different from a seawall since they only protect against erosion, while the latter can also prevent flooding.

To date, there are two types of revetments that property owners can maximise. These are exposed revetments and buried revetments.

Exposed revetments are sloping structures that can be made from natural stones or concrete blocks. These materials help these structures enhance wave energy absorption and reduce reflection and wave run-up. Exposed revetments can also be made from sand-filled geotextile fabric bags, mattresses, and tubes, protecting the whole structure from ultraviolet light. Buried revetments, alternatively, are structures built as part of a strengthened dune. 

Revetments’ Major Benefits

With the construction of revetments across shorelines and coastal areas, they can effectively provide tons of benefits to nearby property owners. 

One of the benefits of revetments is they can absorb almost all energy from waves, currents, and tides. They can also absorb the energy from heavy storms and other similar occurrences. As revetments absorb the energy from these elements, property owners can ensure that the nearby soil will not be displaced quickly. Since soil displacement has been mitigated by revetments, they expect their properties to remain stable. They likewise do not have to worry about instances of coastal erosion.

Another benefit of revetments is they do not hamper the living conditions of nearby water creatures. Revetments feature some gaps between their parts, allowing living creatures and aquatic animals to move in and out of the water without any difficulties. As more animals live nearby, property owners can expect their shoreline to be preserved and remain intact.

One more benefit of revetments is they are affordable. Compared to seawalls and bulkheads, revetments can already be built without costing too much money. They can likewise perform for a long time, especially when they are made from reliable materials.
