With the hole finally dug out, we have been sorting out the bits and pieces that will be placed down, down into the pit! Not much visible work is happening especially our video camera cannot see right into the hole! So you will have to imagine us hard at work 2.5m (8feet) down!

Day 7 – Tuesday 17th August

The delivery of the extra 10 tubes we needed and the wooden battens for constructing the framework to hold up the earth tubes and keep them steady while we fill in the hole around them. We also ordered another 10 bags of cement just in case we need to bed or lock in anything down. Today’s work was shortened as we had to go shopping (we have to eat something)!!!
We did some investigations in the bottom of the hole to see how much work is needed in moving the sand around to lay the earth tubes down. We checked the depth and laid two concrete blocks to get a feel for a particular method to achieve a satisfactory results!

Day 8 – Wednesday 18th August

We had visitors around so it was another late start. We cut 4 tubes into 12 pieces and clamped them together. These are the vertical tubes for transferring the air up out of the ground and into the house. We also mounted a wooden framework at the garage end ready for the vertical 3m (10feet) tubes.
The 120 crates arrived from Jewsons today – these crates called AquaCell are designed to allow large amount of water (usually rain) to be collected and leached out of the sides.

Day 9 – Thursday 19th August

The hired tiny little earth mover machine arrived today and used our mini digger to lift it into the hole! It got stuck in the soft sand!

So we got on with cutting 6 earth tubes in half and mounting them vertically on the support framework – these tubes transfer the incoming air from the Garage down into the cool earth!

Then did the other end where the 12 tubes done yesterday were situated near the point of the house. At both ends we placed the concrete blocks underneath to support them.
