The concrete had set by Saturday lunchtime and in a way I was grateful it was later rather than earlier in the morning for I had arisen quite late. I had been very tired the evening before after all the work I had done. I didn’t want the day to pass by without doing at least some more work on the project. I needed to erect some shuttering in preparation for pouring a finer concrete mix to form the sloping edge into the pit I was constructing.
A long length of timber was screwed to the pit floor against which I placed a length of plywood strengthened with timber and leaning toward the original floor edge. I fastened some timber to the original floor which acts to prevent the plywood from touching the floor at the top. This left an intended gap so that the concrete can be poured into the space and also to make a solid concrete edge along the complete top edge. It will be easier to understand when you see the completed work. After doing that work I began to tackle the removal of the concrete block at the end of the pit.
The yellow handle of the lump hammer rests upon the block. It was protruding out of the floor and we have no idea at the moment as to why it is there. Near to the end of the hammer shaft is a piece of steel tubing and another one a couple of centimetres further away (higher in the picture, click to magnify). They seem to be electrical conduits that have been set into the concrete block. Again we are not sure why they are there. The concrete block itself stands upon another block of concrete but it is of a different composition. The lower one looks like traditional concrete made using granite stones whereas the upper one, that which I am aiming to reduce in height, has been made using broken pieces of brick instead. It is as hard as nails and extremely difficult to chip away at. As I write this on Saturday evening I am almost there but it will take some time yet to lower it enough to be able to tile over it. Work will be resumed on Monday. Tomorrow, Sunday, I will be resting from work.
