    Hi,

    I’m building a retaining wall using concrete blocks laid flat. Is there any reason why shouldn’t use 140mm blocks, just thinking as an amateur block layer it will mean fewer joints?

    Are 7NF blocks the standard I should be using?

    Thanks in advance.

    Jon

    Not familiar with your 7NF reference, but bog standard "dense" (not aerated) blocks from any building supply company for well under £1 each. Standard size 440x225x100mm. Be sure to put some gaps or pipes through to allow drainage, otherwise you'll end up with a dam. PavingExpert.com is a great resource - scroll down to near the bottom to see retaining wall guidance

    No I'm sure you haven't been ripped off - my recollection on price was down to having bought via a mate's trade account
