NANOFIX Methodology for Roof Garden Waterproofing

Step-1:- Surface preparation

• Surface should be dry cleaned by removing loose scales, dirt, dust, grease, oil etc. by wire brush.
• Any visible cracks to be repaired with Nanofix Plastoseal or Nanofix BITUSEAL.
• Junction between mother R.C.C. slab and parapet wall should be cleaned thoroughly and sealed with Nanofix Plastoseal or Nanofix Bituseal.
• All other annular gaps of pipes should be first grouted using cement, sand mortar with or without stone chips.
• After hardening and curing of mortar, the same is finished with Nanofix Plastoseal or Nanofix Bituseal.
• For additional protection, a fillet to be formed with cement sand mortar in 1:4 ratio admixed with Nanofix SYLO 200 (conforming to IS 2645-2003 & IS 9103-2000) at the halot portion (at the junction of parapet & mother slab ) to stop the water percolation.

Step-2:- Application of Nanofix Protective Solutions over & above the prepared surface

2.1 – Application of Nanofix Torch Membrane over & above the prepared surface.

Application Process :

• At the beginning the surface needs to be primed with Nanofix Torch Membrane primer.
• Lay Nanofix Torch Membrane, polyester reinforced APP membrane. Maintain an overlap joint of 100 m.m
• Laying of screed of M20 grade at an average 50 m.m. thickness over APP membrane admixed with Nanofix Sylo 200 (conforming to IS 2645-2003 & IS 9103-2000) @ 200 ml per bag of 50 Kg of Cement. The screed should be laid maintaining a slope of minimum 1:100.

2.2 – Application of Nanofix Flexeet over concrete screed as per recommended methodology.

Application Process :

• Mix Part A with Part B homogeneously and then add Water slowly to make Brush Applicable Coating (Mixing Ratio – Part A : Part B: Water = 1:1:1)
• Apply First Coat by Brush
• After drying of First Coat for 6 to 8hrs (Depending upon Weather Condition) apply Second Coat by brush uniformly
• Application of Nanofix Flexeet must be extended over the parapet wall upto 300 m.m height above the junction of parapet & RCC slab.
• Sprinkle Sand on applied surface before lying cement sand mortar of 1: 4 ratio at an average 50 m.m. thickness after second coat drying of 8hrs.

OR Application of Nanofix Bituflex over concrete screed as per recommended methodology.

Application Process :

• Stir the Product well before Use
• Apply First Coat (Primer Coat) of Bituflex by brush
• After drying of Primer Coat within 4 to 5hrs (Depending upon the Weather Condition) apply Second Coat (Top Coat) by brush uniformly
• Sprinkle Sand on Top Coat (When Tacky) before laying Plaster or Screed after 24hrs.

Step-3:- Application of Nanofix Protective Solutions over & above the prepared surface

• Dump or place soil before plantation.

Note :

• For critical or extensive roof gardening, Nanofix suggests laying of Nanofix torch membrane over the screed before placing soil replacing use of Nanofix Flexeet / Nanofix Bituflex.
• Nanofix also recommends lying of drain board with geotextile of 100 to 150 gsm ( depending on requirement ) before placing soil.
