We have a shed. With concrete slab. Then I poured a bit out the front - 700mm - to slope down to ground level so's things could be rolled in and out of the shed easily. What's the proper name for such as that?
And then to stop rain drips eating away at the ground right at the edge of the slab and undermining it I will pour about 700mm wide concrete 80mm deep all around the shed extending the slab out but 20mm lower than the slab top making a walkway, or a path, or an extension ? What should that be called?
Are there 'proper' building terms for these things or do we just call 'em whatever we like?
