Sam and Joel have been busy setting up the rest of the ICF forms for the lower ground floor – forms not blocks you note (had my wrist slapped over this mistake). Wednesday we were able to pour the lower ground floor walls. We now have ‘rooms’ we can walk, well crawl, in and out of. Progress!
Monday Paul and Dave started taking away the shuttering from the reinforced wall. This took most of the week. Joel, Sam and Dan started on the ICF walls for the lower ground floor. The ICF blocks are made of expanded polystyrene. There are two layers of EPS which sit vertically with plastic spacer bars in between to hold the EPS sheets at the correct distance apart. This gap will be filled with concrete next week. Steels are placed in the gaps to add to the strength of the walls. The blocks have a cog wheel edge top and bottom that helps them fit together. With the size of blocks the wall for the lower ground floor grew very quickly. It started to feel like a house! James joined the team on Thursday and by the evening the majority of the blocks were in place together with the system that will support the walls when the concrete is poured next week.
The structure necessary to support some eighty tonnes of concrete in a vertical plane is massive but on Saturday we were there and yes……. finally we have poured our retaining wall. This time we had six trucks of concrete. The walls were built up in layers as each load of concrete came in. This required two men to control the concrete pump and a team behind to ‘poker’ the concrete to make sure it settled evenly. There will be some video to show the action on the blog later. At the end there was sufficient concrete for us to line our new pond…..
Steel yourself………we have a criss-cross grid of steel neatly bound together at the intersections all lying inside a shuttered base. When all the slab area is covered then we will pour the concrete. It feels like we have sufficient steel to hold up the whole of Barnes Lane!
Sailors beware – don’t try swinging your compass anywhere near Wynford.
We have uploaded some movies: check out the action under ‘Enabling and Groundworks’ on the right hand side of the blog
