HOV Environment is a global specialist in the area of unique erosion solutions either on the coast or rivers.
HOV Environment's goal is to construct innovative solutions that have minimal impact on the environment whilst solving the problem at hand.
Geotextile Solutions

Geotextile Submerged Structures stop wave energy offshore and redirect ocean currents. This effect serves to protect the coast from the erosional effects of the ocean environment- resulting in the protection of homes, businesses, beaches and other coastal assets.

Geotextile Solutions stabilize beaches by forming a salient- a wider, more stable section of the beach. Geotextile Solutions take into account the value the beach provides for local communities, business and tourists. Seawalls and other coastal armouring do not protect the beach, they only protect the land behind it. Beaches across the globe draw in large numbers of tourists and due to this many business thrive, with no beach there are no tourists.

Geotextile Solutions - Better than the Alternatives

Unlike other traditional anti-sea erosion efforts, Geotextile Solutions actually take into account the value of the beach to the local community, businesses and tourists. Seawalls and other forms of structures on the beach do not protect the beach- only the land behind it.

Jetties and groynes create blight and in certain situations, beach erosion Seawalls have severely damaged or destroyed many of the world's beaches

Geotextile Solutions vs Rock Options

Whilst Geotextile Solutions are seen as the future to solving sea erosion, geotextiles can still be used in traditional coastal protection structures like sea walls and anti-sea erosion bunds. Historically these structures have been created using rock. In the past decade advancements in geotextile technology certain solutions have emerged:

Availability of Rock Supplies/Dual Benefits with Geotextile Bags

The availability of specific classified armour stone is becoming a more cost intensive task, especially if project sites do not have access to the correct types of rock and quarries locally. This lack of availability and transport costs can result in a larger cost impact on the project. Certain solutions to this is to implement the project using smaller rock units, this can cause instability to the structure and create additional impacts to the project.

With the use of sand filled geotextiles it allows the planning authorities to provide dual benefits. There are constant dredging projects taking place in river mouths, ports and beaches to remove excess sand in navigation channels. This sand is usually stockpiled and neglected. With the use of sand filled units it is possible to take this unwanted sand supply and provide erosion solutions.

Soft Solution

In many cases sediment movement within a beach is a constant changing process. There are a number of examples where over periods of time a long term hard structure like rock could start to cause adverse effects. If this occurs it is usually very difficult and cost intensive to either remove the structure or re-design the structure to fit with the change in sand movement. With a geotextile solution if changes occur existing bags can be cost effectively removed, by releasing the sand in the units. If required new bags can be put in place to accommodate any future design changes.

Sustainability/Eco Friendly

In terms of sustainability and 'green friendly' the carbon footprint is significantly lower with Geotextiles in comparison to rock armour. A research paper explaining this in more detail is attached.

Marine and Vegetation Benefits

The non-woven geotextile used in previous projects has proven to act as a very effective platform for providing a habitat for marine growth. A number of independent studies have showed the geotextile material out-performs rock and wood/bamboo for marine biology cultivation.

Aesthetic/Visual Impact

The geotextile material used is either submerged in water and cannot be seen by users of the beach, which allows the natural beauty of the beach to remain in place whilst providing erosion protection. In some cases geotextile units are placed on the beach to form a sea wall, the geotextile used is sand coloured and is not deemed as much as an eye sore as a rock or concrete structure.

Taking into account the marine and vegetation growth, over time the geotextile bags will further blend in with the local features of the beach. Additional options to reduce the visual impact is to incorporate dune growth into the geotextile material, making the structure look more natural and provide another line of defence.
