Week 2, day 5:
- Delivery of a 20-tonne lorry load of stone chippings.
- This will be used to stop the area by the site cabins becoming so muddy in wet weather.
- 20 tonnes of stone chippings looks at lot smaller than you’d think!
- Completing the excavation of the second (southern) GSHP collector trench.
- Installing marker pegs in the foundation trenches to indicate the required depth of the foundation concrete.
- The overview photo shows the laser level used to ensure the pegs were all at the right height in relation to Finished Floor Level.
Week 2, Day 5
Stone chippings delivery
Southern GSHP collector trench completed
Both completed GSHP collector trenches – each one is 1.5m wide, 50m long and they’re 10m apart with the excavated soil piled “outboard” to allow access up the central 10m track for laying the sand required below and above the collector pipes, and for installing the pipes themselves. At this stage the further trenches for the pipework tails connecting back to the house had not been dug.
Depth marker pegs in house foundation trench, ready for concrete. This is the trench at the north side of the house where the ground slopes away; the pegs on he southern side are much further below ground level.
