DLF Residential Tower — Terrace Waterproofing

## Project Overview [Full project narrative to be written before launch. Key points to cover:] - Scale: 80,000 sq ft across podium deck and rooftop terrace - Client: DLF (residential tower, Hyderabad) - Primary challenge: large contiguous substrate with multiple penetrations (plumbing risers, drainage outlets, expansion joints) - Method selected: SBR-modified cementitious membrane — chosen for flexibility, bond strength, and compatibility with subsequent tile overlay - Application sequence: substrate preparation → crack repair → primer coat → two-coat SBR system → protection screed - Site coordination: 32-member crew, phased over 6 weeks to allow simultaneous work across zones - Handover: May 2024 - Post-handover: Two monsoon seasons with zero leak complaints reported as of January 2025 ## Substrate Condition at Intake [Detail the substrate condition found at site inspection — age of existing waterproofing layer, existing cracks, ponding areas, previous repair attempts.] ## Method Selection Rationale [Explain why SBR-modified cementitious was selected over alternatives — e.g., why not torch-on membrane, why not polyurethane coating. Cover tile overlay compatibility, application speed at scale, and cost-to-performance ratio for this project type.] ## Execution Highlights [2–3 paragraphs on what made this project technically interesting — expansion joint treatment, penetration waterproofing details, drainage slope correction.] ## Post-Handover [Warranty status, any follow-up visits, outcome summary.]
