I have a basement carpark, with access for parking on the roof of the carpark. We want to use block paving in herrignbone pattern for the access ailes and parking bays. But usually any concrete platform I've work with before have all been pedestrian areas only so using flags on pedestals was standard to allow for drainage below the flags and off the concrete terrace.
So my question is what way (or can) block paving be laid in this application?
What I'm afraid off is that the buildup underneath (sand bedding) is going to be too denses to allow any moisture to drain anywhere. and that leading to an array of problems both for the paving and the waterproofing of the basement carpark roof...
I have though of using a Permeable Paving system as the clean course aggregate buil-up would allow for better drainage below the block surface, to the outfall point off the concrete terrace. But budget is tight so hoping there is some way we can use standard block paving, but on what sort of build-up.....any ideas or suggestions???
Thanks
