Secutex® Soft Rock – Geotextile Sand Containers for Sustainable Coastal Protection
Resilient shorelines for a changing climate.
Smart, flexible and sustainable solutions for coastal and inland waterway erosion control across Australia and the Asia-Pacific region.
Smarter Coastal & Waterway Protection
Rising sea levels and more frequent extreme weather events are increasing pressure on coastlines, waterways and infrastructure.
Traditional hard structures such as rock armour are often expensive, rigid and disruptive to the natural environment.
Secutex® Soft Rock geotextile sand containers provide a proven, sustainable alternative — combining high strength, flexibility and environmental compatibility.
Designed for both temporary and long-term coastal protection, they deliver reliable performance while preserving natural landscapes.
Available types:
- Secutex® Soft Rock: durable, high-performance protection for permanent applications.
- Secutex® Green Soft Rock: biodegradable option for temporary or nature-integrated works.
Whether your goal is enduring stability or reduced environmental impact, Secutex® Soft Rock adapts to your project’s specific requirements — without compromise.

Key advantages and customer benefits of
Secutex® Soft Rock sand containers
High-strength, long-lasting performance
Manufactured from BAW-tested, high-quality needle-punched nonwoven geotextiles,
Secutex® Soft Rock provides:
- Excellent tensile strength and seam reliability
- Service life potential exceeding 50 years, depending on application
Natural UV protection
The open-pore nonwoven allows sand embedding into the surface, creating a natural protective layer that:
- Minimises UV degradation
- Extends the service life for exposed applications
Efficient installation and cost savings
- Quick, simple placement
- Minimal reliance on heavy machinery
- No on-site sewing machines or compressors required
- Reduced downtime and site disturbance
Sustainable local sand fill
- Containers can be filled with on-site or locally sourced sand
- Reduces handling, transport and overall CO₂ emissions
Superior stability under wave action
The textured nonwoven provides excellent soil and inter-container friction,
reducing slippage and enhancing performance in dynamic marine conditions.
Natural UV protection
The open-pore nonwoven allows sand embedding into the surface, creating a natural protective layer that:
- Minimises UV degradation
- Extends the service life for exposed applications
Secutex® Soft Rock – the sustainable alternative that delivers safety, strength and savings.
Safe, Natural and Aesthetic
Unlike rigid rock structures, Secutex® Soft Rock geotextile sand containers are soft, rounded and safe to walk on – even barefoot.
They blend naturally into sandy environments, providing high public amenity and visually appealing coastal protection ideal for tourism and recreation zones.
