Hello,
the time has come - the old exposed aggregate concrete slabs at the entrance gate through the front garden are to be replaced by a mix of various concrete pavers/slabs. For this purpose, we are collecting various formats (also a few natural stones and bricks will be mixed in) and will lay them in a random pattern (otherwise it doesn’t really work).
Now to my question: under the exposed aggregate concrete slabs there is an about 25 cm high sand layer (grain size up to max. 2 mm - I suspect building sand). Whether the layer underneath was compacted I can hardly say ... in any case it is not gravel but rather appears like a collection of topsoil, stone and brick debris. The whole thing is quite firm (whether it was actually compacted or if the years have simply left their marks, I cannot say). Do you think I could simply lay our stone mix in place of the exposed aggregate concrete slabs without the stones sinking within a short time?
Thanks very much for your advice.
Best regards, Chrisu
