SLAB PREP & DRAIN WORK

THIS WEEK WE GET THE SLAB PREPPED AND CONCRETED. FIRST THE INSIDE IS DUG OUT TO ALLOW FOR HARDCORE THEN WE PUT IN 2.5 TON OF SCALPINGS (20MM TO DUST) WHICH IS COMPACTED WITH A WACKER PLATE.

NEXT WE BLIND THE STONE WITH SAND .(TO STOP THE STONES PUNCTURING OUR 1ST DPM). THEN WE COMPACT AGAIN.
NEXT IS DPM NO 1 THEN WE LAY OUR 125 MM POLYSTYRENE INSULATION ON TOP. A 100MM X 25 MM STRIP OF INSULATION IS PUT IN AROUND THE PERIMETER TO STOP COLD BRIDGING.
NEXT IS THE 2ND AND MAIN DPM . THIS ONE IS CUT AND TAPED NEATLY AT THE DOOR OPENING.
NEXT THE CONCRETE GOES IN AND IS TAMPED THEN TROWEL FINISHED WITH A 4 FT LEVEL (FORGOT OUR FLOAT)
WE ALSO INTALL THE GULLEY AND PIPEWORK INTO THE INSPECTION CHAMBER.........ENJOY
