Nara Native Turf Best For Erosion Control

Introduction

Turf in recent research has proven to be one of the best erosion control products, testing far better than silt fences, coir logs and erosion socks for both erosion and silt containment. Established turf by itself can easily handle 1.5 metres per second flows. Well established turf has been shown to handle flows of 2.5 to 3 metres per second.

The biggest problem with using turf in flow areas is that until establishment, it can shear away. Traditionally this was solved by using turf combined with netting and pegs, or turf secured with wire pegs. Both netting and wire pegs can be dangerous hazards to foot traffic, and they are both expensive methods. New E-Staple biodegradable pegs, which have been designed to grip into the ground are proving to be far superior, lower cost and safer.

Tests in the USA showed that the 150mm E-Staple took 12 times the force to remove compared to a round top 150mm steel staple, and more than 4 times that of regular 150mm steel staples.

Testing method

Now that there are such strong biodegradable staples, it was decided to test which would fail first, the staple or the turf. It was also decided to test what force is require to pull 6 x 150mm and in another test 6 x 100mm staples from the ground, pegged through Nara™ Native Turf and regular Wintergreen Couch turf.

All rolls were of good quality. A bamboo stake was secured to wire, and a weighing device attached. 10 separate measurements were taken for…read more
