Foundations: Aztech will undertake to reduce ground levels to accommodate the new base works, setting aside any paving slabs to be reused to make good the previously paved area only. Construction of 400mm wide concrete foundations up to maximum depth of 1000mm, reinforced with a minimum of two steel bars.
The above specification does not include for any instruction received from the building control officer that are unforeseen and outside of our control, and which may incur addition costs.
Drainage: Aztech will endeavour to reposition manhole covers and gullies that are situated on the site required for the new construction to another external location. Where this is not possible we will raise and double seal manholes and gullies.
Rainwater disposal: Any existing rainwater drainage pipe work that falls within the scope of works are repositioned as necessary. From the conservatory rainwater outlets, pipe work is run into the existing rainwater system if possible and if not, into an Aquacell soak away system.
Reinforced suspended floor slab: A sand and cement screed will be laid by Aztech, varying in depth between 35mm and 75mm to match the existing screed level within the property. This to be laid upon a 150mm thick concrete oversite slab that it suspended onto the new foundations and reinforced with a structural mesh. The floor structure is damp proofed using a 1200 gauge damp proof membrane and to prevent heat loss through the floor, a 50mm flooring grade insulation is used.
External wall construction: Aztech will endeavour to match as closely as possible the existing external finish of the property be it render, face brick work, or natural stone. The internals walls can be constructed with either face brick work or with a thermal block and plaster finish. The cavity wall construction allows for the application of 50mm of semi rigid cavity insulation batts.
