Laying the waterproof concrete floor

April Fool’s day – not a joke but very stressful!

I had to coordinate a number of groups of people and activities to get this to happen – Tom and his boys, Phil the concrete expert, the concrete pump and delivery of 33 cubic metres of concrete. Everything was due to start at 8 am.

Shaylor’s concrete pump was there at 07.30 ( but it did only have to come from Greenland’s farm – a mile at most). Then the message came that the first of 5 RMC lorries were on their way. Phil, Tom and the boys were all stuck in traffic. The concrete only has a two hour shelf life and had to come the long way round because of the weak bridge at Pangbourne.

After much nail biting the first lorry arrived and Phil added the waterproofing chemicals. But the mix was very dry and the pump operator was not keen to put it through his pump in case it stuck and set solid.

A small amount of water was added and it pumped successfully although it was very stiff and hard for the boys to manoeuvre.

The second lorry arrived and things started to go smoothly – then near disaster. The third lorry didnt arrive and an hour later we were still waiting. The pump had to be washed out to prevent damage and a lot of angry words were exchanged.

Eventually all the concrete came and the basement floor was finished at about 1.30. A lot of clearing up and then everyone disappeared to leave the concrete to dry.
