Reinforced LeveeEXPLANATION

  • Concept

    This reinforced structure is built on an existing levee to raise the height of levee in order to redirect or prevent flood.
  • Application

    Existing levees that seek for enhancement in height.
  • Characteristics

    1. Reducing the usage of concrete to restore the natural scenery.
    2. Making use of in-situ soil to reduce both construction cost and environmental impact.
    3. Enhancing the function of an existing levee.
    4. Levee with limited space can also be raised with this method.


  • Foundation Levelling

    Clean the ground surface of the site, and excavate in accordance with the leveling layout. Then compact the ground to the required compactness.

  • ACEGrid® Laying

    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.

  • Sand Bag Stacking

    Fill the sand bags and cross-stack them to the designed height.

  • Backfilling

    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.

  • ACEGrid® Wrap-around

    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.

  • Slope Shaping

    After anchoring the ACEGrid®, perform backfill and soil compaction again. Use excavator grab or available compactor to compact and shape the slope to requirement.

  • Layer-by-Layer

    Repeat step 2 to 6 to achieve the required height specified in the design drawing.

  • Slope Vegetation

    Perform slope vegetation to get a green and natural appearance, and also enhance the slope’s resistance to erosion.
