This may be a daft question, but do not want to discover the hard way what not to do! Hope someone can help (unfortunately I'll be offline Sat-Tues so please won't be able to respond immediately if you need clarification).
The question is about a conservatory base and how to go about the concreting/screed stages. The area is 2.5m x 4m, with the long side against the house wall, so the plan is to mix and pour concrete in sections 2.5m x 1.5m (ish) for ease of tamping.
Can I pour the concrete then top off with a screed mix, then tamp down, or should I tamp down the concrete then wait (if so, how long?) before adding the screed and tamping that down? Or should the screed be applied across the whole base in one go?
And...how quickly or not should I place the adjoining section? Should I be aiming to finish the whole base in one day, removing the shuttering once the concrete has set enough to stay put and moving across to the next section? Or should I wait for one section to go off, then do the next section the following day? (will be using a cement mixer rather than having ready-mix delivered)
I was planning to put the DPC beneath the concrete, but could it go between the concrete and screed?
The plan is finish the floor, eventually (!), with ceramic floor tiles.
All advice gratefully received.
