1) All the flat portions of footings / underground structures shall be applied an epoxy based bituminous layer for protection against ground water.
2) RCC surface (footing faces, plinth beam sides, below PCC, periphery of the building) below ground level should be given approved anti-termite treatment.
3) Backfilling shall be started after footings are cured. Backfilling shall be carried out in layers of 300mm to 450mm thick good quality murrum, which shall be well watered (up to Optimum Moisture Content) and compacted by using mechanical vibrator.
4) Date of casting should be displayed on concrete surface with identification after deshuttering to monitor curing.
5) If honeycombs observed are of repairable nature (which do not require demolition of member, in the opinion of Structural Consultant), the same shall be rectified by using approved non shrink mortar mixed with bonding chemical.
6) If it is intended to have plaster or masonry against the concrete structure, the surface shall be hacked (approx. 60/70 hacks each 2-3mm in depth, 1” length and 1” apart per sq ft) within 48 hrs after deshuttering or it is preferable to use approved bonding agents instead of hacking.
7) Reinforcement bars projecting above cast concrete shall be cleaned, using wire brush.
8) Tie roads and PVC pipes must be removed immediately after deshuttering.
9) Columns below natural ground should have 20mm additional covering or as recommended by structural consultant and Winged Cover Kanda should be used to maintain alignment of reinforcement and covering.
