Discipline

Envelope Systems

The skin of the building — weather-tight, thermally sound, and detailed for longevity.

Why this matters

Our position.

Most building defects we see in 5-year-old Hyderabad homes are envelope failures — efflorescence on plaster, leaks at slab-wall junctions, sun-cracked window frames. The envelope decides whether the house ages with grace or becomes a maintenance project. We over-spec joints and waterproofing relative to drawings.

Scope of Works

What this discipline covers.

  • External plastering and waterproofing
  • Window and door framing assemblies
  • Roof systems with insulation and drainage
  • Façade detailing and coatings

Approach

How we deliver.

Our delivery commitments specific to this discipline. These are part of the agreement, not just intent.

  1. 01Waterproofing layer on every horizontal surface that holds water — terraces, sunken slabs, planter boxes — under warranty for 5 years
  2. 02Window and door frames installed with backer rod and gun-grade silicone, not just mortar
  3. 03External plaster done in two coats with a 7-day gap, not rushed
  4. 04Drip moulds and weather sills detailed at every external opening

Materials & Standards

What we specify.

We name vendors so you can verify them. Substitutions require a written variation order from your end.

  • Waterproofing applied as full systems (primer, membrane, top coat) — not single products — selected per surface and exposure
  • Wall plaster: 1:6 cement-sand, screened sand only, river sand only after gradation testing
  • Windows: aluminium or uPVC profiles per architect's specification, set with backer rod and gun-grade silicone
  • External paint: high-performance exterior systems with a minimum 8-year warranty against fade, peel, and chalking

Quality Controls

How we verify.

Every check produces a record that goes into your project file. You can ask for any of them at any point.

  • Hose-pipe test on terraces and balconies before tile-laying — 24-hour flooded test
  • Adhesion test on plaster after 28 days curing
  • Window installation checklist signed by site supervisor and joinery vendor
  • Pre-monsoon inspection of the entire envelope before first rains

Other disciplines
