2017-3-1 · Any particular reason for 100mm screed and not 75mm depth with the extra 25mm going to improve your insulation depth. One sheet of 50mm to cover the first fix pipe work then overlapping with a 100mm sheet. Or build it to suit 200mm insulation if the budget can stretch that far. No reason that I am aware of.
egories. Screed is quite simply a thin, top layer of material laid over a concrete subfloor, that is traditionally made of sharp sand and cement, similarly to concrete. Industrial screed can be used for more heavy duty appliions by using a more coarse 6-10mm aggregate. It is used to cover structural flooring concrete, and can be applied
