EROSION CONTROL
Coir ECB, Landlok TRM, Pyramat HP-TRM, geocell, silt fence
Short to medium term biodegradable and permanent solutions to erosion and sediments
Does the area need to withstand high velocity from winter snow melt or flood? Is there high runoff caused by other factors such as developments and paving? What is the condition of the soil?
The answers to these questions can assist in selecting the right product type for your project. Permathene supplies all of the following:
- Erosion Control Blanket (coir mat)
- Turf Reinforcement Mat
- High Performance Turf Reinforcement Mat
- Geocell soil containment to stabilise earth banks
- Silt Fence and trenching machinery to prevent sediment

Coir is a natural erosion control product made from coconut fibres designed for temporary (6 to 24 months) applications. The product is supported on both sides by a synthetic (photo-degradable) mesh.
Coir erosion control blanket protects exposed slopes from loss of topsoil. It also greatly enhances seed and water retention allowing for faster growth.
Landlok TRM (Turf Reinforcement Mat) is a range of permanent erosion control products.
- Landlok 1051: X3 fibre polypropylene, net (topside) and geotextile (underside)
- Landlok 450: X3 fibre polypropylene, 2 nets (topside, underside)
- Landlok 300: Woven X3 fibre polypropylene
Pyramat HP-TRM is the most sophisticated vegetation enhancing mat on earth! Exceptional UV resistance.
Pyramat is a high performance 3-dimensional permanent TRM (Turf Reinforcement Mat).
- 10 times stronger than traditional TRM's
- Ideal for extremely steep slopes
- Has 3 times the UV resistance of a conventional TRM
Geocell is an effective cellular confinement system providing a cost-effective solution for ground stabilisation, erosion control and earth retention on slopes.
An innovative geosynthetic product Geocell is a lightweight and flexible cellular structure made from connected polyethylene strips. By ultrasonically bonding the strips together an extremely strong and flexible configuration is produced.
A variety infill materials can be filled into the geocell system; aggregate, concrete, sand, soil, etc.
In order to ensure sedimentation control during construction and to comply with the Resource Management Act and the District Plan it is mandatory to prevent runoff and sediment discharging off site or into the stormwater system.
This is achieved in part by installing silt fence barriers around the perimeter of the earthworks. A silt fence needs to have an adequately high UV resistance for the term required, plus it must meet specific filtration properties.
Syntex silt fence is available in two styles depending upon the performance requirements of the project.
