Pyramat - High Performance Turf Reinforcement Mat

Are you dealing with a tough erosion challenge on a steep slope or in a high-flow waterway? Pyramat is a game-changing, high-performance turf reinforcement mat (HPTRM) engineered to lock down soil and vegetation. It offers permanent, resilient protection for your most demanding projects, from vulnerable shorelines to intense stormwater channels, ensuring you achieve a sustainable and robust finish.

Product Description

Pyramat is a unique, three-dimensional, woven polypropylene geotextile. Its core strength comes from a patented matrix, which creates a uniform configuration of pyramid-like projections for incredible interlock with both soil and root systems. This innovative structure enhances stability and encourages rapid root mass development, essentially turning your vegetated surface into a high-strength armour. With an expected design life of up to 75 years and superior UV resistance, this product delivers a reliable, long-term erosion control strategy that won’t let you down.

Applications

Steep slopes and hillside stabilisation
Vegetated channels and high-flow waterways
Shoreline and bank protection
Stormwater and drainage channels
Permanent erosion control on landfill caps
High-stress areas requiring energy dissipation

How Pyramat works

The Science Behind Pyramat’s Performance Pyramat is classified as a High-Performance Turf Reinforcement Mat (HPTRM), a distinction earned through its multi-component structural design. The product matrix is fabricated from woven polypropylene monofilament yarns, utilising a proprietary fibre technology to form a three-dimensional, lofty structure. This configuration exhibits a uniform pattern of resilient pyramid-like projections. This geometry is key to achieving exceptional interlock and reinforcement capacity with both the in-situ soil and the developing root system.

The mechanical properties are evidenced by its high tensile strength of 58.4 x 43.8 kN/m. Crucially, its long-term performance is underpinned by a proprietary ultraviolet stabiliser package, ensuring a minimum of 85% UV resistance retained at 10,000 hours. When fully vegetated, the combined root-soil-mat composite is independently proven to withstand severe hydraulic stresses, tolerating a maximum shear stress of 766 Pa and a maximum permissible velocity of 7.6 m/sec. For applications demanding even higher resistance, the Pyramattress system is available, which constructs a geosynthetic/soil/rock composite to resist scour and intense hydraulic forces, providing a cost-effective alternative to traditional hard armoring.

Pyramat is your long-term engineered solution for controlling erosion on challenging sites. Simply put, it’s an ultra-tough woven mat that reinforces the ground, stopping soil from washing away on steep slopes and in fast-flowing water. The mat’s unique 3D structure creates a powerful anchor for seeds and root systems, rapidly establishing a strong, natural vegetative cover. Unlike short-term erosion control blankets, Pyramat is built to last, providing up to 75 years of dependable protection against hydraulic forces, UV light, and even fire.
