Spent the morning laying the 3 layers of material down. 1st layer was standard geo-textile (grey), 2nd layer was the waterproofing EPDM rubber membrane (Black) and last was Polyfelt padding (White). The rubber was the hardest to get in position as it is one piece (of course!) and quite heavy in total.
Once the wrappings were done laying the crates was straight forward and by the end of the day 2 of the 3 layers were placed.
Did preparation work for installing the rainwater tank. Started by marking out and leveling the sand for the base of the tank, we spent so time getting the right as we don’t want the tank to be off level!
Then we humped the 87 aquacell modules down into the hole from their delivered location next to the house.
Had a relaxed day today. Went and purchased some mini access chamber raising rings and a lid to use on the rainwater tank for access into it.
Then made a hole in the top of a aquacell module for a raising ring, attached it and removed the bottom of the module to make a hole right through. Made the same size hole right thorugh another module for the middle layer of the tank, then made a hole in just the top of a final module for the bottom of the access shaft. We will place a submersible pump here.
Installed the rainwater soakaway this afternoon. We carefully leveled the area in the corner of the trench and then placed geo-textile down. Then installed 18 Aquacell modules in a 3m x 3m array, the modules were clipped together. A hole was made in to top to allow connection from the rainwater system. Finally the geo-texile was wrapped around all 6 sides.
