Thanks George, it's been a long time in the doing but it's nearly there now thank goodness, I've since made an access door into the garage which makes life a bit easier.
You're so right about those mats, they fit together very neatly too, I'm only putting them down where I'm going to be standing and walking though, so they'll be a continuous run along the workshop from the door to the garage access and in front of the benches and machines,
I'm leaving the machines standing on the bare concrete for now, I've painted the floor anyway, so that cuts dust and makes sweeping up easier, but if I change my mind then it's just a case of slotting new mats in.
I first saw these on a promo' in B&Q but they'd all gone when I went back to get a few packs, but they still had them on their website available for local collection, think they're about a tenner a pack, money well spent!
Mine are branded 'Rolson'
