Hello All, Would very much appreciate your collective experience on this problem I have. My 1930's house has concrete paving at the front and rear of the house. It needs repairing where I have dug drains etc. and I would like to match it as best I can.
I think the concrete is made from bideford sand, which is supplied locally. It has small particles of shell. If this sand is left in the rain, the small particles wash away and it has a similar texture to the paving. I was going to mix up some 4:1 cement using the bideford sand and mix in a quantity of black concrete dye to match the colour (I would try various quantities of the dye until it was a close match).
I have the driveways, paths and patios book which is excellent, it helped me lay the block paving in the first picture above. It mentions an admixture to use with concrete paving that brings the larger particles to the surface. Can anyone tell me what admixture I should use to get this effect.
Thanks Ed
