Building a conservatory... 5m x 3m, .. stage now at - up to damp
proof course with double brick wall, about to put down concrete base
Question and advice please..
About 10 yrs ago I put in a block patio... put down scalping then sand
( plate vibrated it) more sand and then laid the block paving. The
paitio is approx 150mm below the house damp proof course. The
bricks are still with in the new conservatory foundations.
Question: can I lay sand on these.. then DPM, then 50mm
..if so, it would save me having to get rid of the block paves .. and
having to refill the void with concerte !!
This would also leave me with 100mm for insulation, screed and tiles.
Advice please on whether to leave the block pavers in situ... Thanks
