Secutex® Soft Rock geotextile sandbags and sand containers

Secutex® Soft Rock are geotextile sand-filled bags and sand containers that are manufactured from needle-punched Secutex® filter nonwoven geotextiles. These sandbags and sand containers provide an alternative to conventional rock materials and replace the ballast and the filter layer in one element.

Secutex® Soft Rock geotextile sand container (GSC) and sand bags can be used to protect coastal structures, dunes and beaches by providing erosion or scour protection measures.

Secutex® Soft Rock sand container applications

  • Erosion control in flowing watersSand container
  • Dune protection
  • Groynes
  • Sea walls
  • Scour protection for waterfront structures, walls, bridge piles, offshore wind turbines and quay-walls in harbours

Secutex® Soft Rock offers multitude of advantages

  • Versatile, sand-filled, soft and flexible construction elements for marine, coastal, river, waterway and harbour structures
  • Excellent tensile strength and elongation characteristics during hydraulic-geotechnical interactions
  • Proven 20-year, long-term performance for scour protection
  • Compared to woven geotextile containers: higher interface friction and higher, proven structural stability
  • Long-term abrasion and robustness performance

Selected advantages of Secutex® Soft Rock sand container and sand bags

Advantage 1: Filling and installation of Secutex® Soft Rock

Secutex® Soft Rock sand container and sand bags can be installed simply with lighter construction equipment while the transport and use of heavy rock can be avoided. The ingenuity of Secutex® Soft Rock construction rests on the ability to fill them with locally available sand. The filter-stable nonwovens provide robust, flexible construction elements that are similar to the natural coastal and marine environment but with greater erosion control.

Advantage 2: Rough surface for better frictional and a stable construction

The roughened surface of the needle-punched nonwoven geotextiles of Secutex® Soft Rock offer better frictional behaviour than comparable systems made of woven fabrics; thus, Secutex® Soft Rock reduces the sliding between stacked sand-filled containers or bags when subjected to currents and waves. Additionally, sand and sedimentation embed itself within the Secutex® nonwoven structure, which gives it a natural protection layer.

Advantage 3: Secutex® Soft Rock sand containers a modern and effective scour and erosion protection system

Secutex® Soft Rock replaces granular filters and rock armour for revetment systems and scour protection of e.g. offshore wind turbine foundations. The sand-filled Secutex® Soft Rock containers provide highly efficient, long-term protection due to the geotextile’s robustness, filtration qualities and weight. There is no need for further granular layers. Installed in advance of monopiles, the system eliminates the risk of erosion during construction. And, the ability to drive piles through the geotextile containers enables quicker, more dependable construction that provides valuable savings to a project.

Conventional scour protection solutions can only be installed with big and expensive efforts, and they typically do not stay in position or when installing in larger water depth the filter material is segregated.

In the past scour protection was constructed with mineral aggregate or a geotextile filter under heavy armor rock. A durable and ­effective alternative is Secutex® Soft Rock scour protection.

The placement of the mineral filter and armor rock layer creates numerous difficulties in large water depths and at high flow velocities and does not provide permanent scour protection. For this reason, more often sand-filled geotextile nonwoven containers have been installed as a more effective solution.

Beach repair and storm protection with visually adapt to the environment.

Beachfronts require long-term protection, and the solutions sought must be flexible, durable, and minimise impact on marine environments. The dynamic interaction between waves and waterfront soils and structures complicates hydraulic engineering.

Secutex® Soft Rock  robust nonwoven geotextiles enable these engineered installations to encapsulate sand (including local fill) for the creation of long-term performing bags and containers.

An additional advantage is that Secutex® Soft Rock adapts visually (color) to the environment.
