Hi Guys,
I am building a garage with an art studio above it. I mention this because the garage part doesn't come under building regs but the studio does?
Anyway, 1m deep foundation trench, 250mm concrete then 3 layers of foundation block are all done. The garage floor slab is poured on top of a DPM which covers the compacted aggregate and sand layers.
The DPN cones up the sides of the slab and over the top of the first course of the inner leaf.
I am now ready to start laying block inner leaf on top of the DPM. The brick outer leaf will be played on a DPC 150mm above ground level. There will be 65mm insulation in the 90mm cavity.
Q: Do i need to install cavity trays between inner and outer leaf around the whole construction at DPC level?
