A terrace takes the most direct load of any surface on a building — standing monsoon water, a full day of summer heat, and the expansion and contraction that comes with it, cycle after cycle. Left untreated or built on an old coba layer that has lost its bond, this movement opens hairline cracks at joints, parapet junctions and drain mouths — the exact points where a terrace begins to leak into the slab below.
Six stages, verified at every step before the next one covers it.
The coating system is chosen after site assessment — exposure, existing surface, and whether heat reduction is a priority. Everything below is applied by a certified Weatherblazer team, never supplied loose.
Single-component thermal-insulating elastomeric coating. Best where roof heat reduction matters as much as waterproofing — SRI 120, up to 20°C lower roof temperature in peak summer.
Single-component hybrid polyurethane membrane. Applies directly over an existing terrace surface — including old brickbat coba — without breaking it out first.
Single-component, water-based aliphatic polyurethane coating. Foot-trafficable, used on roofs, podium decks and areas that see regular movement.
Cold-applied, single-component elastomeric emulsion membrane. Highly resistant to chlorides and sulphates commonly present in soil — a strong choice for harsher exposure.
Transversely flexible, longitudinally rigid expansion-joint tape. Resists water pressure above 5 bar — used at base-parapet connections and wide or irregular cracks.
25 m rollSelf-adhesive butyl-rubber tape, aluminium-backed (AL) for flashing or fleece-backed for areas that will be coated over — drain mouths, corner joints, pipe penetrations.
Roll — width/length per siteReady-to-use crack filler paste. Withstands limited linear movement — for non-moving joints and cracks up to 8 mm.
1 kg & 4 kgPolymer modifiers blended into the repair mortar for honeycombed and damaged concrete — improve bonding, flexibility and resistance to water ingress.
Primer coat applied before the waterproofing system, so the coating bonds fully to the prepared concrete surface.
