Hollow core up

Got the hollow core up yesterday. I had a bit of tidy up to do before the 2 artic lorries came at about 11. They took about 3 hours to get all of the slabs in place using a mobile crane. They had a bit of cutting for doing around the chimneys. It all went off without a hitch despite the weather being a disaster with driving rain and strong winds.

Grouting
After that was done, the hard job of grouting the joints needed to be done. We did it the following way in which we managed to do it without killing ourselves up and down ladders. While the slabs were being lowered onto the house we went to Westport to get a trailor fix of sand, aggregrate and cement. When the slabs were in place and the crane was free, we filled a large container with the mix and got the crane to lift the container onto the slabs. Then we emptied the container. We did this 4 times until the trailor was empty. We shovels and a brushes we filled in the joints with this dry mix. Fortunately, it started to rain heavily and the rain that fell allowed turn the mix into concrete. A hard job done quite easily.

Propping the slabs
We had to prop the slabs downstairs for the long span to support the blocks for the upstairs. We put in place a temporary stairs for the moment.

Whats up next?
Upstairs blocks are starting today so, lets see how much will get done before xmas. Plan to start the slates on the garage next week.
