To hold soil together and prevent soil loss from runoff; also to provide a base for vegetation.
To collect and drain the water out of the reinforced structure for structural stability.
To enhance the draining function of the structure.
To separate different materials and provide certain degree of draining and filtering functions to the structure for overall stability.
To reinforce and stablize the structure with the designed strength.
Clean the ground surface of the site, and excavate in accordance with the levelling layout. Then compact the ground to the required compactness.
Cut ACEGrid® to the size specified on the design drawing (including at least 2 meters in length for wrap-around purpose). ACEGrid® should be laid flat without any corrugation. Anchorage should be done with the anchorage interval specified on the design drawing.
Fill the required number of sand bags and cross-stack them to the designed height, forming the wall facing of the structure.
Backfill soil at the back of the sand bag facing; the thickness of every layer should be between 15 cm to 30 cm. Then, perform compaction from the facing inward to the backfill area to meet the required compactness specified on the design drawing.
Wrap the sand bag around with the reserved length of ACEGrid®; make sure it is free of corrugation. Anchorage should be done with the anchorage interval specified on the design drawing.
After anchoring the ACEGrid®, perform backfill and soil compaction again. Use excavator grab or available compactor to compact and shape the slope to requirement.
Install drainage material in accordance with the design drawing to reduce the pore water pressure in the backfilled area.
Repeat step 2 to 6 to achieve the required height specified in the design drawing. Make sure drainage system is installed at required height.
Perform slope vegetation to get a green and natural appearance, and also enhance the slope’s resistance to erosion.
