TARAcrete Micro Concrete Roofing Tiles

The Aesthetic, Durable and Inexpensive Sloping Roof Alternative

Classic styling with the latest in modern concrete technology



Micro Concrete Roofing (MCR) tiles are made from a carefully controlled mix of cement, sand, fine stone aggregate and water.

The mix is vibrated at an optimum frequency for forty-five seconds on a precision engineered TARA TileMaker screeding table. It is then transferred to High Impact Polystyrene moulds that give MCR tiles their unique profile. After initial setting in an airtight environment for 24 hours, the tiles are cured in water for a period of 7 days. This process gives MCR tiles unmatched strength and durability.

MCR tiles undergo stringent quality control at every step. They are put through rigorous tests for water tightness, strength, shape and size.

The TARA TileMakerMCR technology is a result of global research and development effort. The tiles are being marketed extensively in Latin America, East and West Africa and South-East Asia. Each year, over ten million tiles covering an area of 800,000 sqm of roofs are installed. In India, MCR technology is promoted by TARA, Development Alternatives in association with SKAT of Switzerland.


MCR tiles offer many advantages over other sloping roof materials such as G.I. sheets, Mangalore tiles, wooden shingles, slate and asbestos. MCR tiles are:

MCR roofs are constructed in a conventional manner using rafters and purlins made from wood or steel. Rafters are typically spaced at 90 cm to 110 cm apart. The purlins are mailed at a distance of 40 cm from each other.

MCR tiles are secured to purlins by tying them to the purlins with G.I. wire. The angle of roof slope should be at least 22°. Greater inclination of upto 30° is preferred for more aesthetic appeal.

Standard architectural details for gable and hipped roof ridges, eaves, side over-hangs and valleys can be used for MCR roofs.
