Free shipping, all orders
UV life up to 75 years
EPA-recognized BMP · Made in the USA
Pyramat is a turf reinforcement mat that is used for permanent erosion control on steep slopes, banks and vegetated waterways. Pyramats are made from woven polypropylene geotextile that is configured into pyramid-like projections. These TRMS have a high interlock and reinforcement capacity that helps stabilize soil and promote vegetation.
High-Performance Turf Reinforcement Mats
Engineered With Patented X3 Fiber Technology
This is a three-dimensional woven polypropylene geotextile. It’s designed with patented X3® Fiber Technology. It’s specifically engineered for superior erosion control on steep slopes and vegetated waterways. This mat offers the highest specification requirements for protection from erosion on slopes, banks, and channels.
It is also the only High-Performance Turf Reinforcement Mat to have a verified carbon footprint by an independent third-party. From beginning to end, the carbon footprint of 1m2 of the 75 HPTRM is 2.7 kgCO2e — equivalent to driving 7 miles.

Pyramat in Action
A Greener Choice Than Hard Armor
It increases vegetation and controls erosion. It’s engineered to lock seeds and soil in place for fast root development for long-term vegetation. The result is a natural-looking appearance versus a colorless rock rip rap or concrete — an excellent choice for living shorelines. Using a High-Performance Turf Reinforcement Mat will maintain cooler temperatures of water than a standard hard-armoring alternative.
The manufacturing facility is ISO 14001 certified, which recognizes Propex as actively measuring its environmental impact and continuously looking for ways to improve its green commitment.
Case Study
Rehabilitation of Woodley Channel, California
Los Angeles County, CA
Replacing rock riprap with Pyramat 75 HPTRM

Pyramat 75 HPTRM
Installed
15,000 sq yds
Design life
Up to 75 years
Result
10+ years stable
Los Angeles County in California needed to repair Woodley Channel after it was seriously damaged by large storms and flooding. LADPW along with the county wanted to re-establish vegetation in the channel which originally used riprap for protecting against erosion.
The previous rock riprap was replaced with 15,000 square yards of PYRAMAT® 75 High-Performance Turf Reinforcement Mat (HPTRM). PYRAMAT® 75 costs a lot less than rock and offers up to 75 years of design life, even when exposed directly to sunlight. Its woven construction was designed to lock in seeds and establish reinforcement to the roots of native vegetation.
On top of being more cost-effective than rock, PYRAMAT® is environmentally friendly. It removes pollutants from the waterways with vegetation, reduces thermal pollution, and decreases greenhouse gases associated with mining, hauling, and placing of rock riprap. High-Performance Turf Reinforcement Mat, like PYRAMAT® 75, has been recognized by the EPA as a Best Management Practice (BMP) for improving the quality of groundwater. PYRAMAT® is the only HPTRM to have its carbon footprint verified by a third-party organization. Its carbon impact is 30 times less than rock riprap and other hard protection solutions.
For more than 10 years, Woodley Channel is stable with no signs of erosion. Vegetation is thriving, offering a natural, aesthetically pleasing outcome.
Project Note: Bell Road, Scottsdale, AZ
The city needed permanent protection for an eroding roadway drainage channel fronting the commercial developments along Bell Road in Scottsdale, AZ. Rip rap and concrete were the most unpopular choices and went beyond the city’s budget. Propex worked with Gannett Fleming using the 75 TRM instead, to reinforce the native vegetation and provide a UV-stabilized, permanent lining able to withstand heavy flows from desert monsoons.
Questions
Frequently Asked Questions
Where is this product made?
The Pyramat product line is made in the USA. The Propex facility in Ringgold, GA is ISO 14001 certified.
How do I install them?
See the installation guides located on each of the product pages.
How do I know which TRM mat is best for my application?
Compare the Pyramat 25, 50, and 75 models above, or use the Erosion Control Product Finder to match a mat to your slope, channel, and flow conditions.
How long will shipping take?
All orders ship for free. Orders typically ship out within 1-2 business days if placed before 12:00 noon EST.
What is the difference between engineered plastic and single-use plastic?
Engineered plastic, like these mats, is stabilized to prevent deterioration and to withstand UV and other environmental exposures. Single-use plastics are not stabilized and will start to break down immediately.
How long will Propex mats last?
HPTRMs (High-Performance Turf Reinforcement Mats) are engineered plastics developed to last a long time or even permanently. The 75 has a lifespan of 75 years when exposed to UV rays; if it is covered with vegetation, its functional longevity can last much longer.
Do engineered plastics leach when exposed to water?
Propex erosion control products are made from polypropylene which contains no leachable components, unlike single-use plastic made from non-stabilized polymers that break down into microplastics and drain harmful chemicals. The EPA has identified HPTRMs as the Best Management Practice for improving water quality because they promote infiltration of water back into the ground table and filter out sediments and pollutants.
