Floor dis level ...

A wall was standing right in this patch on the floor, which was also creating a dis level in the floor tiles 0f 5/8,s which is no problem if you are laying a carpet like i had before, but now i decided to lay a parquet and it needs a level floor so i decided to create a step in order to achieve my wishes, the higher floor as you can see in figure 4 that of a 6 inches of hard core and sand will be right under the desk, right where the speakers will be standing enough of that will be serving as a good acoustical de-coupling.

In order to form a step i need to have a layer of concrete, so i need sand 3/8 gravel and cement,
and a strip of wood for the edge.

In this case the piece of would will remain in the place,placed on the lower part of the floor the strip of wood which is the same height of the other part of the floor, i will explain why, i laid the concrete 1cm lower from each sides, so before i lay down the parquet the remaining 1 cm will be filled with sand which will be again serving as a good acoustical de-coupling, since over it the desk will be placed.

{Something that i like to add which i learned through experience that might come in handy is, if you ever mix some extra concrete that you want to use later lets say same day instead of throwing it away and make a new mix put the concrete in a strong plastic bag and it will hold wet and soft for ages}
