MacMat

Macmat R turf reinforcement mat is a three-dimensional geocomposite. It is reinforced with a double twist steel wire mesh to provide tensile mechanical strength and erosion protection, ensuring the stability of roadways, embankments, drainage ditches, channels and other areas susceptible to erosion damages.

When constructing MACMAT R, the following points should be taken into account:

1. Material Inspection: Before construction, carefully inspect the quality of the MACMAT to ensure it is free from damage and contamination and meets the design requirements.

2. Construction Environment: Ensure that the construction site is level, dry, and free of waterlogging, and avoid construction under adverse weather conditions.

3. Foundation Treatment: Before laying the MACMAT, the foundation should be leveled and compacted, removing any surface protrusions to ensure a flat foundation surface.

4. Laying Sequence: Lay the MACMAT according to the sequence specified in the design drawings, ensuring that the laying direction of the MACMAT aligns with the main load-bearing direction.

5. Anchor Method: When anchoring with U-shaped nails, ensure that the material and size of the nails meet the requirements, with the anchoring spacing generally being 1 meter, forming a plum blossom pattern.

6. Secure Connections: The connections of the MACMAT should be secure, with the connection strength in the load-bearing direction not less than the design tensile strength.

7. Tightening and Smoothing: When laying the MACMAT, it must be tightened and smoothed, nailed down, and closely adhered to the subgrade surface to avoid wrinkles and distortions.

8. Offsetting Seams: When laying multiple layers of geosynthetic materials, the upper and lower seams should alternate, with the offset distance not being less than 0.5 meters.

9. Protective Layer: The MACMAT should not be laid directly on hard sub-layers such as gravel. A 5cm thick layer of medium to coarse sand should be laid between the geosynthetic materials and the gravel.

10. Avoid Damage: During construction, avoid damaging the coating on the MACMAT and try to minimize porosity.

11. Compaction: When the thickness of the cushion layer and fill material on the MACMAT exceeds 0.5 meters, heavy compaction machinery can be used to compact the material densely.

12. Safe Construction: During construction, adhere to safety operation procedures to ensure the safety of construction personnel.

13. Record Keeping: Keep detailed records during construction, including material usage, construction steps, and inspection results, for future reference.

14. Post-Construction Maintenance: After construction, regular inspections and maintenance should be carried out on the MACMAT to ensure its long-term stability and service life.

By following these points, the quality and effectiveness of the MACMAT construction can be effectively guaranteed, extending its service life.
