Concrete Extension Floor - How Long Until Celotex Insulation And DPM Before Screed?


Postby JLR » Mon Nov 11, 2013 8:31 pm

Hi,

We are having an extension built and have been let down by our cowboy builder. We are trying to complete the extension by retaining the existing workers and managing it to completion ourselves.

The builder has built the extension, but left the concrete slab floors till the end, this is were we are up to, we have done the hardcore, and bind it with sand, laid the first layer of DPM and the concrete is being poured tomorrow.

Our question is once the concrete is down how long do we have to wait to lay the celotex 100mm insulation and the final layer of DPM before we put the screed on?

The extension is water tight.

Thanks!
