Retaining Wall & FloorRetaining Wall:Treatment on + ve side:• Brush / spray application of impregnation product called Protekta
Base which fills the fine pores with crystalline silicate growth, coverage 2 Sq. M / Ltr.
• Brush application of one coat of Protekta Flexjoint on the construction joint only. Thickness of application will be approx. 0.5 mm.
• Plastering at the Starter Joint, Construction joints and any other defects like honeycombs, tie-rod locations etc with polymer sealant 500 modified mortar.
• Brush coat of Protekta Plastofelt primer• Brush coat of Protekta Plastofelt to provide a very strong coating to
resist hydrostatic pressure.• Brush coat of Protekta Top Seal Coat as hard layer. After the
application of this layer, plastering is not required.Treatment on –ve side: · Injections/Grouting at starter joint & construction joints with Protekta
Grip / Protekta Hydro Grout.
FloorTreatment on + ve side:• After PCC has been laid, grout Protekta SB mixed with
Protekta SS and catalyst at regular intervals of every 1 M center to center. This grout material has property of expanding when it comes in contact with water. It forms a water impervious layer and prevents travel of water to the top of PCC.
• Spray of Protekta Base on PCC surface towards porosity reduction.
• Application of a slurry prepared with Protex B & Protekta SLM. This layer is a hard layer & will be abrasion resistant.
• A coat of Protekta Ceal 540 on concreteTreatment on –ve Side• Injection/grouting at a regular intervals at all joints
between floor and column joints and construction joints
Podium Slab with Gutter (Hard & Soft Scapes)
Podium SlabAssumptions Made:• Gradient is provided in the slab at the time of
casting.• Water from this sloped surface flows into the
Gutters.• Ridge points are at the Podium Slab, midway
between the Gutters on either side.
Treatment Steps• Brush / spray application of crystallisation/gel formation
product called Protekta Base which fills the fine pores with crystalline silicate growth, coverage 2 Sq. M / Ltr.
• Brush application of one coat of Protekta Flexjoint on the construction joint only. Thickness of application will be approx. 0.5 mm.
• Plastering 6” wide at the construction joints.• Brush coat of Protekta Plastofelt to provide a very strong
flexible coating.• Application of Protekta Abrasion resist as hard layer. After the
application of this layer, plastering is not required.• Injections/Grouting at construction joints/cracks from below.
• Optional, a coat of Protekta Procoat or Protekta Wall Top
• Please note that we have not suggested any plastering on our treatment since the final surface is abrasion resistant.
Gutter Treatment• Brush / spray application of crystallisation/gel formation
product called Protekta Base which fills the fine pores with crystalline silicate growth, coverage 2 Sq. M / Ltr.
• Brush application of one coat of Protekta Flexjoint on the construction joint only. Thickness of application will be approx. 0.5 mm.
• Plastering 6” wide at the construction joints.• Brush coat of Protekta Plastofelt to provide a very strong
flexible coating.• Application of Protekta Abrasion resist as hard layer. After the
application of this layer, plastering is not required.• Injections/Grouting at construction joints/ Cracks from below.
Slope Creation:• With M20 grade Concrete laid to slope.
