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.
Different options for different needs
Secutex® Soft Rock sand containers come in a variety of sizes, colours and even materials to suit every need.
Secutex® Soft Rock Smart
Geotextile sand container with factory made, patented closure technology. A durable, robust solution that is optimally matched to the tensile force-elongation properties of the geotextile sand container.
Secutex® Soft Rock Grand
Geotextile sand container with a filling volume of 2.5 m³, which can be filled and closed via two filling inlets. A geotextile sand container made of an abrasion-resistant double-layer filter geotextile, an extremely robust double seam and rounded corner areas that are insensitive to damage.
A sand container with exceptional position stability under hydraulic impacts.
Secutex® Green Soft Rock
Geotextile sand container made of biodegradable raw materials for coastal protection, scour protection and erosion control along flowing waters. An alternative to the classic geosynthetics.
Solutions with Secutex® Soft Rock
River bank protection
Secutex® Soft Rock sand containers provide an alternative solution to conventional erosion control systems or revetments made of rocks or concrete. With the use of GSCs and an underlying filter nonwoven Secutex® H an effective erosion protection system can be achieved. Secutex® Soft Rock sand containers made of single or double-layered nonwovens can be applied with or without an additional protection layer for covered or uncovered applications.
Coastal and dune protection
Secutex® Soft Rock is installed in front of or above soil materials in order to retain the soil material behind or underneath while providing sufficient resistance to hydraulic loads. In consideration of their soft and adaptable properties, GSCs are best suited for coastal protection systems, for example inside sand dunes or in front of steep coasts.
GSCs are installed as scour protection system in the water around structures, e.g. offshore wind turbine foundations or bridge foundations.

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.
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.
