Wall backfill has begun

The backfilling of the retaining wall has begun, now that waterproofing is complete. We are putting in a couple of Ag-pipe drains covered with 20mm aggregate. So far 40 cubic metres of aggregate has been delivered, and we may need more with the 88 metre long wall. The aggregate with agg-pipes will be wrapped in geo-fabric to keep the silt out but let the water in.
