External Wall Waterproofing – Service Overview
External wall waterproofing applies to plaster, concrete, or masonry facades using cementitious slurries, elastomeric paints, PU membranes, or silicone sealers before final painting. Systems handle thermal movement, UV exposure, and crack-bridging up to 2mm for 7–10 year protection.
​

What we do
Power wash and patch cracks/honeycombs, then apply filler and primer for uniform adhesion across uneven plaster or concrete.
​

Brush/roller 2–3 coats of polymer-modified cementitious coating or liquid PU membrane, reinforced with fiberglass mesh at stress points.
​

Seal joints, window/door frames, and parapets with silicone or PU sealant to stop water tracking at edges.
​

Top with breathable elastomeric paint that allows vapor out while blocking liquid in, tested via water spray for 48 hours.
​

Where we are expert
Apartment facades and independent houses with plaster finishes prone to monsoon black streaks and peeling.
​

Exposed boundary walls and parapets needing durable, UV-stable coatings without scaffolding for heights above 2 floors.
​

Renovation over old failed systems where surface profiling ensures new layers bond without delamination.
​

What makes us unique
Elastomeric systems (Asian Paints, Dr. Fixit) with 300%+ elongation to bridge live cracks from settlement or thermal cycling.
​

Vapor-permeable coatings preventing trapped moisture unlike rigid cement paints that blister interiors.
​

Scaffold-free rope access or swing stages for multi-story buildings, minimizing resident disruption.
​

5-year warranty with monsoon inspection and touch-up clause for edge detailing around ACs/windows.
