When using Mac Mats (especially reinforced Mac Mats), it is important to pay attention to the following key points to ensure their effectiveness and safety:
Site Leveling and Cleaning: Before construction, the site should be thoroughly leveled and cleaned to ensure the foundation is flat, dry, and free of debris, allowing the Mac Mats to closely adhere to the base.
Adherence to Design: Mac Mats should be laid strictly according to design requirements, including direction and slope, to ensure overall integrity and stability.
Macmat should be stretched and laid flat to avoid wrinkles and twists, ensuring close contact with the roadbed surface.
When laying multiple layers of Mac Mats, the seams of the upper and lower layers should be staggered, with a stagger distance of no less than 0.5 meters to enhance overall stability.
Mac Mats should not be laid directly on hard sublayers such as gravel. A protective layer of medium to coarse sand should be laid between the geosynthetic material and the gravel to reduce wear and increase stability.
Use specialized fixing nails or anchors to secure the Mac Mats, ensuring they do not move or deform during use.
The spacing and number of fixing nails or anchors should be calculated and determined based on the specifications and load-bearing capacity of the Mac Mats.
Overlapping Requirements: The overlapping of Mac Mats should be done according to design requirements, generally using a method of overlapping or staggering. The overlap length should be no less than 1.5 times the width of the Mac Mats to ensure overall integrity and stability.
Avoiding Damage: During laying and use, care should be taken to avoid damaging the Mac Mats. Any damage should be repaired promptly to avoid affecting their overall performance.
Regular Inspection: The condition of the Mac Mats should be regularly inspected during use. Any issues such as damage or deformation should be addressed promptly.
Chemical Protection: Avoid contact of the Mac Mats with chemicals to prevent compromising their performance and lifespan.
Traffic Management: If the construction area is near traffic roads or densely populated areas, traffic management should be strengthened with warning signs, direction boards, and temporary isolation measures to ensure traffic order and pedestrian safety during construction.
Soil Erosion Protection: In the design of Geomat erosion control, soil erosion issues should be considered, and appropriate protective measures should be taken based on actual conditions, such as adding anti-erosion materials or setting up protective layers.
Professional Consultation: Before using Mac Mats, it is advisable to consult and evaluate with civil engineers or experts in the relevant field to obtain more specific and professional advice and assistance.
