![]() For permanent structures, special protection may be required.ģ Revetments Rock revetment, Port Klang, Malaysia Port Klang is the largest and busiest port of Malaysia. Here, the locally sand-filled containers replace imported rock-fill to create massgravity structures that are stable and erosion resistant. Dykes and groynes: Geotube, Geocontainer and Geobag units may be used for dykes and groynes. For permanent structures, an outer layer of rock armour and a rock underlayer may be required. Here, the locally sand-filled containers replace imported rock-fill to create mass-gravity structures that are stable and erosion resistant. ![]() ![]() Breakwaters: Geotube and Geocontainer units may be used for the cores of breakwaters. For permanent structures, special protection techniques may be required. Here, the locally sand-filled containers replace imported stone and rock to create a stable slope protection layer. Revetments: Geotube and Geobag units are used to protect exposed soil slopes from erosion. TenCate s geocontainment solutions can be applied to the following coastal and marine structures. TenCate s geocontainment solutions have lower carbon footprints than conventional, wholly rock-fill solutions. TenCate s geocontainment solutions utilize the contained local sand-fill to substitute for imported rock-fill and thus create greater value and better environmental practice. These solutions, utilizing TenCate s Geotube, Geocontainer and Geobag units, can be employed above, at and below water level. These geocontainment solutions allow the movement of water while at the same time prevent loss of the sand-fill from the containers. Here, the geocontainment solutions contain local sand-fill to provide permeable, mass-gravity structures that are resistant to erosion.

Mirafi and Polyfelt geotextiles are used as filters to prevent loss of the retained soil through the stone and rock in dykes and groynes. Dykes and groynes: Dykes are embankments that retain water and soils, while groynes are small embankment-like structures that control the littoral movement of beach sand. Mirafi woven geotextiles are used as horizontal filters beneath breakwaters and bed protection to prevent erosion of the foundation soil which can cause instability of the structure. Breakwaters and bed protection: Breakwaters are offshore structures that dissipate wave forces, while bed protection is horizontal revetments that protect the beds of rivers, harbours and ocean outlets from scour. Polyfelt and Mirafi geotextiles are used as filters beneath rock revetments to prevent the protected soil from eroding out of the revetment. The outer revetment layer(s) are designed to resist the external water forces while the inner layer(s) are designed to prevent soil erosion. ![]() Revetments: Revetments provide surface erosion protection for soils. TenCate s geotextiles solutions can be applied to the following coastal and marine structures. These solutions, utilizing TenCate s Mirafi and Polyfelt geotextiles, can be employed above, at and below water level. Geotextile solutions are very cost effective as they substitute for single or multiple gravel layers. TenCate s geotextile filters are used where it is necessary to prevent the erosion of soil through stone and rock layers while at the same time allowing the relatively free movement of water. For these applications, the geotextile acts as a permeable protection layer - a filter - enabling relatively free water movement while protecting the adjacent soil from erosion. 1 Geosynthetics for Coastal and Marine Engineering Protective & Outdoor Fabrics Aerospace Composites Armour Composites Geosynthetics Industrial Fabrics GrassĢ TenCate s geotextile solutions TenCate s geocontainment solutions TenCate has geotextile solutions for many coastal and marine engineering applications.
