This is me at the Harrogate Homebuilding & Renovating show standing on an Eco Slab.
What is an Eco Slab? Well, I hadn’t seen one before but the fact that it was being demonstrated on the stand of Logix, one of our best known ICF suppliers, gives you a clue. Because what ICFs are to walls (i.e polystyrene moulds), Eco Slabs are to floors.
• You level the hardcore base
• You cover the floor with 1m square eco slabs, which have little polystrene legs
• You then pour a re-inforced concrete slab. The thicker the concrete, the wider the achievable span.
Will it catch on? I’m not sure. What you end up with is a hybrid which is not quite a solid slab (because there is air beneath the eco slab) and yet not quite a suspended floor (because the legs of the eco slabs rest on the ground). Does it require ventilation, as a suspended floor would? Not sure. And if not, then why not just build a solid slab? Off to the website to find out more but the website just shows up as a blank page in all my browsers, which doesn’t inspire confidence in the company behind it.
But it certainly supports a 15 stone blogger, and his Costa Coffee latte.
