Im having a conservatory built, the conservatory will be built on a an exsisting concreate foundation ( currently home to a garage ). My question is....if the conservatory supplyer fits the new conser on top of theses exsisting founds, will i need to lay a DP membrane and or insulation before laying a wooden floor. What are your recomendations please. Cheers Dude DIY
Baseworks aren't my area of expertise but you will need a dp course in for sure, especially if you plan on installing a wooden floor! Water tracks up through brick and concrete and would deffinately get to the flooring.
