Birla Opus Alldry Deep Waterproofing Guide

This guide follows the current Birla Opus manufacturer architecture: diagnose the moisture problem first, then select the exact waterproofing system. Product-page claims, PIS evidence, warranty documents and Islamia's commercial layer are kept separate.

Diagnosis-first workflow for Islamia

Location: terrace/roof, parapet, exterior wall, bathroom, balcony, tank or other area.
Symptom: seepage, damp patch, efflorescence, crack, water ingress or heat exposure.
Surface: concrete, plaster, masonry, existing coating or other substrate.
Preparation: cleaning, algae removal, crack/joint repair and primer/system layer where required.

Important source conflict protection

The current Wall n Roof 12 product page highlights a 12-year warranty, while the current PIS/warranty documentation distinguishes terrace warranty from exterior-wall warranty and describes up to 14 years for exterior walls. Islamia should not collapse these into one generic “14-year warranty” claim. The page should show the application-specific warranty language.
