⚫GeoMarine Double Layer Tubular GeoMattress

Flexible tubular mattress is a fast and effective river bund erosion protection method where the system is durable, permeable, enhancing natural vegetation growth and does not harm the environment.

GeoMarine Sand Filled GeoMattress is the ideal choice when riverbanks, waterway sections and impoundment slopes require erosion protection with a long term vegetation cover in place.

It is economical, easy to install and uses simple equipment without the requirement for skilled labour. sand filled GeoMatress is manufactured with a special substrate integrated to the upper surface for instant green effect, providing a surface texture that enhances the rapid establishment of vegetation and shielding UV attack.The Sand filled Mattress is delivered in rolls which can be easily transported to site. Laid with parallel tubular sections running down the slope, each are hydraulically filled with sand through the top openings. The sand is introduced through a small hopper and washed down with water pumped from the waterway or impoundment. Adjacent rolls of Sand Filled GeoMattress are joined by seaming on site. Finally, the Sand Filled Mattress is anchored in a trench at the top of the slope.

 

What’s Double Layer Tubular GeoMattress?

Double Layer Tubular GeoMattress is a fast and cheep erosion protection method where the system is durable, permeable, allows plants to grew on it, and does not harm the environment. This system is variable and adaptable, enabling tailor made erosion control solutions.

Double Layer Tubular GeoMattress is a flexible erosion control system composed of filter-cloth and granular materials. Made of green coloured composite fabric, this largely pre-fabricated empty mattress can be easily delivered at site. Filling with suitable material that can be found nearby and the equipment or tools are mostly small and easy to mobilize has made this GeoMarine system most popular erosion control product in wet area.

Applications

⚫ Riverbank Protection.

⚫ Mining Areas.

⚫ Flood mitigation chanel and protection works.

⚫ Protection of the sea-bed around jetties.

⚫ Navigational canals and waterways

 

Filling Method

1. Pneumatic Material Filling

⚪ Suitable for large areas of Double Layer Tubular GeoMattress have to be installed.

⚪ Sand is blown through a flexible hose into the tubes using compressor and sand hopper with feeder.

 

2. Dry Material Filling

⚪ Suitable for large areas where can be filled in a dry conditions.
⚪ Steel or PVC pipe is inserted into the GeoMattress tube, sand is dropped through the fill-opening in the pipe and subsequently rammer down with a concrete rammer, Compacted sand ballast inside GeoMattress is the advantage of this method.

 

3. Wet Material Filling

⚪ The wey material filling system is similar to the dry filling method using rammer. The sand is being washed down by a water jet. This will provides a more continuous process with well compacted sand ballast in the GeoMattress.

 

Anchoring

It is advised to anchor the mats on top of the slope in a trench when GeoMattress is being used on steep slopes or in the areas with strong currents process with well compacted sand ballast in the GeoMattress.

 

Material Properties

⚫ GeoMattress is made of a white or green coloured non-woven composit fabric being sewn together with woven geotextile to from tubes at regular interval.

⚫ The upper woven composite fabric made of Polyester or Polypropylene is needle-punched with UV stabilized white of green fibers and tape yarns.

⚫ The lower woven fabric is made of UV stabilized Polypropylene.

⚫ Overlap Flaps width is 150mm, Sewing thread with 1,000N tensile strength and 20% elongation at break will be stitch at 40mm lengt
