Building Construction
Complete material solutions for residential and commercial RCC construction in Andaman
Shop All Building Materials →Building a home or commercial structure in the Andaman & Nicobar Islands comes with unique considerations — cyclone resistance, coastal corrosion, and the challenges of island logistics. Saran Traders has been the trusted construction materials partner in Andaman for years, supplying everything from foundation TMT bars and cement to roofing sheets, structural sections, and plumbing pipes. We help builders, contractors, and homeowners source all materials from a single, reliable supplier.

Step-by-Step Guide
How to approach your building construction project
Foundation & Footings
Lay isolated or raft footings using Fe-500D TMT bars as per structural design. Use M20 to M40 concrete with OPC or PPC cement. Place cover blocks (50mm min.) to protect reinforcement from soil moisture. Proper foundation is the single most critical step for building longevity.
Ground Floor Columns & Beams
Erect RCC columns with the designed TMT bar configuration. Construct grade beams connecting all column footings. Before backfilling, apply a waterproofing coat to all below-ground concrete surfaces. Column concrete grade should be M25 or above.
Brick & Block Masonry
Lay walls using AAC blocks (preferred for Andaman due to light weight and thermal insulation) or conventional red bricks. Use horizontal band beams at lintel level (typically 2.4m from FFL) and sill level with TMT bar reinforcement to tie the frame together against seismic and wind forces.
RCC Roof Slab or Sheet Roof
For multi-floor construction, cast RCC slab using M25 concrete with TMT reinforcement as designed. For single-floor residential or utility structures, a steel frame with roofing sheets is more economical. Ensure adequate slope (minimum 1:50 for RCC, 1:10 for sheet roofs) for drainage.
Plumbing & MEP Rough-in
Run CPVC or GI Pipes for water supply within walls before plastering. For coastal Andaman, CPVC & GI pipes are preferred for hot and cold water supply for their corrosion resistance. Lay drainage pipes (PVC) with correct slopes toward the drainage system.
Finishes, Roofing & Handover
Complete plastering, flooring, and painting. Fix window grills and balcony railings (SS 316 recommended). Install roofing sheets if applicable. Connect water supply from storage tanks. Final check: ensure all structural members are adequately protected with paint or galvanizing.
Frequently Asked Questions
Expert answers to common questions about building construction
QHow much TMT steel and cement is needed for a 1000 sqft house in Andaman?›
As a rough rule of thumb for a 1000 sqft single-floor RCC house: TMT bars — approximately 4 to 6 metric tonnes (Fe-500D, including foundation, columns, beams, roof slab). Cement — approximately 300 to 450 bags (50kg bags) for the RCC work. These are estimates only — your structural engineer's bar bending schedule will give exact quantities. Always add 5 to 10% wastage.
QWhich is better for plumbing in Andaman — GI pipe or CPVC?›
GI (Galvanized Iron) pipe is the traditional choice and still widely used for hot and cold water supply in Andaman. It is highly durable and resistant to mechanical damage. However, over 15 to 20 years, scale buildup can reduce flow. CPVC pipes are modern and corrosion-proof but require careful UV protection if exposed. For Andaman's coastal houses, GI for main supply lines and CPVC for distribution within walls is a practical combination.
QAre there special structural requirements for Andaman's seismic and cyclone zone?›
Yes. Andaman falls in Seismic Zone V (highest risk) and Wind Zone V (55 m/s basic wind speed). This means: (1) Your structural design must conform to IS 1893 (seismic design) and IS 875 Part 3 (wind loads). (2) Use Fe-500D TMT — mandated for Zone V. (3) Ensure proper stirrup spacing in columns (75 to 100mm in plastic hinge zones). Always hire a qualified structural engineer for approval drawings.
QHow do I prevent concrete corrosion in Andaman's coastal environment?›
Corrosion resistance in Andaman starts with the concrete mix: (1) Use minimum M25 grade with low water-cement ratio (0.45 or less). (2) Maintain minimum 40mm clear cover for columns and beams, 50mm for foundation — use cover blocks. (3) Consider adding corrosion inhibitor admixtures in critical zones. (4) Apply waterproofing coatings to all external surfaces. Inadequate cover is the number one cause of structure failure in coastal areas.
QCan I source all my construction materials from Saran Traders?›
Yes. Saran Traders is one of Andaman's most comprehensive construction material suppliers. We stock TMT bars (multiple brands and diameters), cement (OPC and PPC), a full range of GI and MS pipes, structural sections (angles, channels, flats, square bars), roofing sheets (corrugated, color-coated, GI plain), stainless steel pipes, water tanks, hardware, and much more.
