mat grass grid/3D grass grid/3D erosion control mat

3D mat grass grid

Description:

 It is a kind of new style civil engineering material, included in the new material and technology field of the national new and high-tech product category as enhancing material.

Features:
It is kind of net patch in three dimensional structure for turf strengthening. It is loose and flexible with 90% space left for filling soil, grit and fine stones, and plant root system can pass through it. Plants can grow soundly with it. The grown turf will combine itself hard with net patch and earth surface together. Plant root system can go deep into 30-40cm underground, so a solid green compound protective layer will be built.

Functions:
1. Protect land surface from the erosion of rain and wind before turf grows up.
2. It can make the grass seeds uniformly dispersed over sloping surface solidly against wind and rain.
3. Black net patch can absorb heat energy greatly, increase earth moisture, promote seed pullulating and prolong vegetative period
4. Its rough surface can make wind and water produce incalculable vortices on the net patch surface so as to play the damping effect and urge the carrier deposit in net patch.
5. The compound protective layer formed after plant growth can undergo high water level and large current velocity erosion (3-4m/s for 2 days, 5-6m/s for 4-5 hours).
6. It can replace those permanent sloping surface protective materials like concrete, pitch and block stone, and be used to protect the sloping surface of highway, railway, river, dyke and hillside.
7. It can reduce construction cost sharply with the cost equaling to 1/7 of C15 concrete and dry pitching cost and 1/8 of grout block stone cost.
8. When it is laid on the surface of sand soil ground, it can prevent sand drift, increase surface roughness and surficial deposit, change terrene physical-chemical properties and improve local ecological environment
