Placement and compaction of a 200mm thick layer of Type 1 across the footprint of the proposed composting pad, prior to placement of a 200mm thick layer of site batched roller compacted concrete over 9480m2.
Construction of 210 lm of cast in-situ concrete lined channel, laid to falls and connected to a HDPE lined lagoon.
