floor screeds

[benbob]

I have a couple of questions,

Where can I get hold of the reinforcing fibres for the floor screed, I have found one place they charge £3 for a 100g bag(i think i would need about 40). This sounds quite expensive to me.

What depth below the door step(for the level door regulations) can I go assuming that i will be laying tiles onto the screed.

Do you really need the screed fibres for your floor screed? Unless you're putting a thinner thickness? You can buy 900kg, might be cheaper(?) Many floor screeds has been done for years without the fibres
