I'm having a new concrete sectional garage and new base for it to sit on. The old base of approx 11' by 18' is coming up along with perhaps half as much again in area of old concrete around the previous garage's footprint. A new base of 11' by 22' is going down comprising of 4" concrete, 4" hardcore, steel reinforcement and damp proof membrane etc. The base will be thickened to approx 6" around the perimeter.
I've been quoted £4.50 per square foot to take up the old, put down hardcore and lay the new. This works out at approx £1,100 (which includes taking up the extra old concrete around the footprint of the previous garage).
Is this reasonable?
Thanks for any advice. Andy
