Micro Concrete Roofing

 

Micro Concrete Roofing (MCR) is a cost-effective aesthetic and durable alternative sloping roof technology. MCR 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, over forty million tiles are installed. In India, Development Alternatives, in technical collaboration with SKAT, Switzerland; introduced the technology under their building material program supported by SDC (Swiss Agency for Development and Co-operation). This technology has been widely excepted, with more than 250 production units currently in operation.

Brief production process
The mix of cement sand, aggregate and water is vibrated for about 45 seconds and then transferred on to a high impact polystyrene mould to give MCR tiles their unique profile. After initial setting for 24 hours, tiles are water cured for 7 days. This result in great strength and durability of MCR tiles.


 Advantages

Offer more value for money
Are highly durable –they have the life of concrete
Are lighter than other roofing tiles- allows cost saving on understructure
Can be easily installed
Can be easily dismantled and reused
Can be coloured to user’s preference
Reduce heat gain
Do not make noise during rains

Areas of Application
A variety of roof designs for farm and country houses, bungalows, verandahs and pavilions are possible with MCR tiles. They have also been used on industrial sheds, workshops and restaurants. MCR tiles offers much versatility for designers, architects and engineers to create a variety of roof forms.
