Geotextile sand container: Secutex® Soft Rock

Geotextile sandbags and sand containers Secutex® Soft Rock

Secutex® Soft Rock geotextile sand containers

Also known as sand bags are manufactured from needle-punched Secutex® nonwoven filter geotextiles. Geotextile sand containers (GSC) are made for encapsulating granular material and are used as building element. In addition to single-layer nonwoven GSCs for covered applications, double-layer nonwoven GSCs are available. They have an integrated surface protection made of rough fibres for exposed conditions and are visually well suited for a sandy environment.

  • GSCs provide the function of a filter and a ballast in one element
  • No additional cover layer required
  • No scouring during construction phase as installed prior to monopile installation

Advantages of Secutex® Soft Rock

Secutex® Soft Rock is the first choice when looking for soft and adaptable erosion and scour protection systems. Secutex® Soft Rock GSCs provide the filter and ballast function in one element. Secutex® Soft Rock GSCs, made from filter-stable nonwovens, are robust, flexible construction elements that resemble the natural coastal and marine environment and provides an excellent erosion protection. They are an alternative solution to conventional revetment systems with granular filters, rip-raps and/or armourstones.

In-situ soil as fill material

A convincing advantage of Secutex® Soft Rock constructions lies in the ability to fill them with locally available sand. This can result in significant cost savings compared to conventional revetment solutions due to reduced construction time, lower material costs and shorter transport distances.

Stability under hydraulic load

The dynamic interaction between waves and/or currents and the soils and structures at the water‘s edge makes the selection of a suitable protection system difficult. Coastal sections or banks (e.g. with buildings close to the coast) must be protected from erosion in the long term. The solution must be flexible and durable, and the impact on the marine environment must be minimal. Lightweight, robust nonwovens make it possible to encapsulate the local sand and thus create efficient geotextile containers for erosion control
measures in the long term.

Secutex® Soft Rock as building material

The roughened surface of the needle-punched nonwovens of Secutex® Soft Rock offers a better friction behaviour than comparable systems made of woven fabrics. Thus, Secutex® Soft Rock reduces the sliding between stacked sand-filled containers or bags when subject to currents and waves. In addition, sand and sedimentation are embedded in the nonwoven structure, providing a natural protection layer for the nonwoven.

CO2 reduction

Geosynthetics can replace the use of conventional construction materials such as armourstone, gravel or sand. This means that fewer stones or soil must be removed and transported and thus, less CO2 is produced and emitted.
