Using Turf Reinforcement Mats TRMs as an Alternative to Rock Riprap For Soil Erosion Control. Soil erosion can pose significant challenges in numerous situations and can have a negative environmental impact if left unchecked. Civil engineers and contractors that often deal with soil erosion control are the ones in a position to do the most to prevent this phenomenon from happening in the first place.
The Different Types of TRMs. Rock riprap has traditionally been used for soil erosion in areas that are unable to support long-term, natural vegetation growth. Yet, the benefits of using turf reinforcement mats TRMs far outweigh those of hard armor solutions. This also becomes more apparent in populated areas where reinforced vegetation is more desirable than rock or concrete.
Turf Reinforcement Mats can handle the stress of high velocity running water and has a superior design life. With its all synthetic composition, TRMs can handle high velocities and shear stress inherent to difficult slope and channel applications.
Before the advent of turf reinforcement mats TRMs in the early 1970s, using “hard armor” materials such as rock riprap and concrete were the standard practice for permanently stabilizing high flow drainage channels, outfall areas, river banks, and shorelines against erosion. Today, more and more engineers and designers are looking for erosion control products that are softer, more aesthetically pleasing, and environmentally friendly alternatives
Permanent RECPs- Turf Reinforcement Mats TRMs In areas exposed to erosive forces that will exceed the limits of natural vegetation, Turf reinforcement mats are necessary for long term vegetative soil stabilization. TRMs are made up of non-degradable nets, fibers, wire mesh, filaments, and other elements that will stay in place for many years.
Turf Reinforcement Mats TRM’s Proven performance has resulted in the widespread use and acceptance of Turf Reinforcement Mats TRMs as a permanent, cost effective and environmentally friendly alternative to hard armor erosion protection solutions such as concrete and rip rap. UV and chemical resistant synthetic polyolefins are manufactured to create a flexible three dimensional matrix.
May 31, 2019· TRMs are often employed as a “green” alternative to stone riprap, pavement, and other forms of hard armoring. They are typically used in a manner that optimizes plant root interaction with the mat structure. Typical installations involve rolling out and anchoring the TRM
Jul 25, 2019· Applications of Turf Reinforcement Mats. TRMs are used across industries like transportation, engineering, military, construction and more with several different applications. These include job sites on water channels, canals, inlets and outlets, shorelines and rivers, levees, dams, dikes as well as any area with a steep slope....
May 31, 2019· TRMs are often employed as a “green” alternative to stone riprap, pavement, and other forms of hard armoring. They are typically used in a manner that optimizes plant root interaction with the mat structure. Typical installations involve rolling out
Mar 07, 2020· Chapter 7 Erosion and Sediment Control Section 7E-18 Turf Reinforcement Mats 2 Revised: 2013 Edition A. Description/Uses Turf reinforcement mats TRMs are a three dimensional product, constructed of synthetic, non-degradable though some products are a composite of degradable and non-degradable materials materials.
Use TRMs for a permanent solution for erosion control while allowing for mature plant growth. TRMs are the preferred environmental alternative to hard armor. Applications include protection in drainage ditches, open channels, steep slopes and detention basins. Manipulate the Turf Reinforcement Mat
As an alternative to rip rap, the two most commonly used types of permanent blankets are High-Performance Turf Reinforcement Mats HPTRMs and Turf Reinforcement Mats TRMs. Photodegradable: Photodegradable blankets are usually made of a plastic netting that intentionally stops functioning after a certain amount of time has passed.
After several discussions with the District 2 Engineers, the suggestion of using the P550 permanent Composite Turf Reinforcement Mats was offered as an alternative to using rock riprap. After going through extensive designs using erosion control design software, the IL DOT chose to specify a high-performing composite turf reinforcement mat C-TRM for the Milan beltway extension project.
How Turf Reinforcement Mats TRMS Can Cut Projects Costs in Half During an upgrade of the Hume Highway the consortium tasked for the design and construction of this project encountered a number of environmentally sensitive areas through which clean water open drains had to be constructed.
Turf Reinforcement Mats are products composed primarily of nondegradable products that enhance the ability of living plants to stabilize soils. They bind with roots to reinforce the soil matrix with longevity greater than 5-years. When and Where to Use It Use TRMs where vegetation alone will not hold a slope or streambank. TRMs enable the use of “green”
Jul 25, 2019· For example, there are LANDLOK® turf reinforcement mats, which are stitch-bonded polypropylene geotextiles used for long-term erosion protection. This TRM reinforces roots and stems as well as supports natural vegetation. LANDLOK® is an effective form of erosion control on moderate slopes as well as swales and low flow channels.
Blankets and mats offer a great deal of versatility, from quick and temporary solutions in erosion control projects to more permanent installations. Choices include lightweight blankets and heavier turf reinforcement mats TRMs as well as hydraulically applied
Turf Reinforcement Mats TRMs provide immediate erosion protection and long-term site armoring. TRMs assist in the establishment of vegetation while permanently reinforcing vegetation for applications where the forces exerted by water exceed the shear limits of unreinforced vegetation. Typical applications include high flow channels, streambanks, shorelines and other areas where rock riprap have typically
The Benefits of TRMs: Turf reinforcement mats are an effective marriage of hard armor and natural vegetation erosion control benefits. The benefits of hard armor are longevity, low maintenance requirements and capability to handle high velocities and shear stresses. This method is very costly however and often cost prohibitive.
