Advice From Engineers and Techies, Please!

This year when we open our garden we shall have three Flamenco dancers performing.

They need a large enough area for them to put their wooden dance floor down, access to power for their recorded music and access to a room for changing.

This is not a problem but we have to decide where in the garden they should be. The logical place is on the patio outside the french doors of the lounge. We can run an extension cable without it being in the way ('elf and Safety!) and they can change in the lounge.

A possible problem that occurs to my very non-technical brain is that the very hard stamping of their heels may damage the patio - depending on how thick and solid their flooring is.

Am I right to be worrying?
The wood will, obviously, spread the load to some extent but would thicker wood make it unlikely to damage the paving and how thick should it be?
Even with thick wood, is it likely that the vibration from the stamping might loosen the pointing?

It would be easy enough to have the dancing on the lawn but then the power cable will have to come out of a door, across part of the patio and across part of the lawn.

Answers on the back of a £10 note, please

 

Thanks, pete

 

I don't know but I'm not sure that it makes a great deal of difference. I guess it's the force generated by stamping their heels that is the main factor.

 

Dohh!!! - but it is after midday

 

Thanks, everyone
