whats the best way of covering copper pipes in floor ?????

[mikanta]

Got a full system to cover over in a chased concrete floor all pipes are lagged with hesian sleeves ??
Some areas of piping 20mm from surface of chase. (not ideal i know but no other real option. plus done now ).
Most chases cross open floor and will need to be up to strength.

Been told to use various methods by different people which is the best ;

1. concrete with 4 to 1 mix using grit sand ?

2.some form of self levelling latex (not sure if the guy appreciated the depth).

3. Some kind of builders foam. (Not sure if this ones nonsense).

Any other suggestions ?

Thanks in advance

Sorry to say, but I reckon the only decent advice is to re-do it as it should be done.

The interaction of copper with both dry and wet concrete should not cause a corrosion concern. However, copper should be protected when it comes in contact with concrete mixtures that contain components high in sulfur, such as cinders and fly-ash, which can create an acid that is highly corrosive to most metals including copper.
For this reason it is good practice to wrap the copper in PVC or grease impregnated (aka "Denso") tape. Specific regulations apply to copper pipe used for carrying gas under the Gas Safety (Installation and Use) Regulations (1998), and pipes buried in floor screeds.

Long runs of copper pipe in concrete are liable to break due to differential thermal expansion.
When cemented or plastered over, "Denso" tape or other flexible wrapping should be used to avoid expansion stresses.
