Dyke construction

In civil engineering and water engineering, dyke structures are special hydraulic installations designed to protect developed areas and infrastructure against flooding and against tidal events and tidal water in general along coasts and rivers. In many cases, dams and dykes are designed with a different inclination on the water side to that on the air side. So-called dyke defence paths are constructed on and next to the dyke for maintenance purposes and for defence in case of a disaster. The main objective of the dam structures is to protect the hinterland from flooding. Along coasts, dyke structures are also of crucial importance for permanent coastal protection.

Dams and dykes play a central role in flood protection. For this reason, their size, type and construction need to be carefully designed and dimensioned. Geosynthetics such as bentonite mats, geogrids, non-woven fabrics and erosion control mats are used here for sealing, separating, filtering, drainage and erosion control.

Dyke construction

BEMAT Erosion Control Mats

BEMAT erosion control mats are three-dimensional non-woven mats made of randomly arranged polypropylene (PP) monofilaments. As the vegetation starts to grow, the mats prevent erosion channels from forming, fix the soil in place and secure it against washing out.

Dyke construction

BENTOMAT Geosynthetic Clay Liners

Geosynthetic clay liners, also known as bentonite mats, are composite geosynthetic materials that have been in use for many years as a successful natural method for sealing against liquids and gases in a wide variety of applications.

Dyke construction

COCONUT-FIBRE MATS and JUTE-FIBRE MATS

COCONUT-FIBRE and JUTE-FIBRE are natural erosion control mats. The grid structure made of 100% natural fibers ensures safe and durable vegetation on embankments and in shore zones. Unwanted soil erosion by wind and water is effectively prevented.

Dyke construction

TERRABENT slope stabilisation and sealing system

TERRABENT is a sealed earthwork structure with a greenable slope inclination of 70°. It is a combination of the statically effective slope stabilization system GREEN TERRAMESH with the geosynthetic clay liner BENTOMAT.

Dyke construction

CONCRETE CANVAS Concrete Mats

CONCRETE CANVAS brings together many advantages in one product: the robustness, fire resistance and durability of concrete combined with the excellent abrasion resistance and sealing properties of the geosynthetics.

TERRAMESH steep slope systems

The reinforcing material in TERRAMESH systems comprises a mesh made of double twisted steel wire. The wire has duplex protection, consisting of a thick galvanised GalMac alloy coating and an additional Polimac coating.

RENO PLUS Mattresses

RENO PLUS Mattresses arose as a sustainable and resourceconserving solution to the multifaceted requirements within the realm of riverbank and riverbed protection. They effectively reduce the ecological impact of riverbank protection measures while simultaneously fostering a near-natural habitat through their full plantability.
