What are your soil type conditions... is it Class M?
Are you still going down the reinforced Masonry blockwork pool structure + Liner path or concrete shell?
You will need Planning Drawings & Building/Engineering
Please leave a PM if you require assistance
@BIM_Engineer I got this response:
So your water level is approx.3m below the ground level
and the deepest end of your pool is 2.1m
Therefore .9m above ground water.. hydrostatic water pressure maybe an issue..more reason not to use pool liners
Also check your storm water disposal.
@BIM_Engineer I think we may bring the depth back to 1.7-1.8m (plus thickness of precast slab). Would that be worthwhile?
By 'pool liner' you mean the internal finish, right? If so, please remind me why. Risk of bubbling or something from ground water/moisture?
Any other things to consider base don the engineer's info above?
