Tips for effective erosion control with blankets, mats and TRMs

Erosion control mats are used to protect soil from rain and wind erosion and to support establishment of a sustainable vegetation.

Cost effective erosion control includes proper understanding of the problem and using the best-value products for a cleaner and healthier environment.

Properly installed blankets perform better than sprayed hydro-mulch in any weather condition.

	Diverse, sustainable, mature vegetation is the solution for successful permanent erosion control.
	It takes time to establish mature, sustainable vegetation. Proper protection for the soil and young plants are required until establishment of mature vegetation.
	Most failures are due to improper product selection and poor installation.

Select the most suitable blanket for each application, the best value product. Strength and durability must be considered when selecting a suitable blanket.

Always use a fresh batch of seeds with high germination rate. Check seed certification in seeded blankets. Be aware!

Select a suitable mixture of seeds depending on the location and time of the year. The mixture should include a seed type with strong root system, a seed type with strong aerial parts a creeping type closer to ground.

Grade the slope or channel or the area properly allowing sufficient space for runoff water. If not, water will find its own way by creating gullies and ruining the restoration efforts.

Make sure to smooth the surface thoroughly before installing the blankets.

Always spread seeds before placing blankets. Blankets will keep the seeds in place, protecting them from birds, wind and rain.

Fasten the blankets properly to the ground with metal staples or wooden pegs. Even the most expensive blanket cannot perform well without properly anchoring it to the ground. Make sure there is good contact between the blanket and the ground.

Generally, use 6" long staples for temporary mats such as jute, straw or excelsior mats. Must use at least 1 staple or peg for each square yard. Longer anchors may required depending on the soil type..

Generally use 8" long staples for heavier and durable coir mats and permanent TRMs. Must use at least 1.5 - 2 staples or pegs for each square yard. Longer anchors may require depending on the soil type.

Do not spread soil over an erosion control mat. This fill soil will wash away easily, wasting your time, money and efforts to control erosion. Be aware !

All erosion control blankets support vegetation establishment. They do not control weeds.

Temporary mats such as jute, straw and excelsior mats should not be used in water diversion channels. They are not strong enough to resist strong flow conditions.

Blankets with photodegradable plastic nets can be a problem in future maintenance of the vegetation as the photodegradable nets can tangle in mowing equipment and destroy the nicely established vegetation.

Blankets with photodegradable plastic nets also interfere with wildlife movement and should not be used in wetlands or on streambanks.

Cutting blankets for planting will reduce their strength. When planting through the mat is necessary, use open-wave blankets to avoid cutting the mat. If the blanket is cut for planting, anchor the open ends to the ground properly.

Green color dyed fiber blankets will not perform any better than non dyed blankets. Color is only for appearance.

	Open-weave semi-permanent erosion control mats
	The best choice for effective erosion control
	Open weave bristle coir semi-permanent mats support vegetation establishment better than synthetic and composite TRMs.

Open-weave blankets - the best choice for effective erosion control

Open weave blankets allows planting through the mat without cutting it.		Open weave blankets allow reseeding if necessary.		Open weave blankets are wildlife safe as the twine move independently (no fixed joints).

Always remember

Failures not only cost reconstruction, but also create extremely expensive and irreversible damage to aquatic life in lakes and streams.

Do it right the first time. Save money, time, our environment and have a piece of mind !
