Hello there,
Please can you tell me if plastisicer (i.e. Febmix) is allowed below ground level? I am building an extension and I am in the process of bringing the brickwork up to ground level but I have heard that you should not use Febmix or any other plasticiser until above ground but I don't know if this is true.

Many thanks in advance,

Lee Hewitt.

I dont beleive its an issue, but consult feb mix to be sure and use a sulfate resisting cement
