The  EM2 structural building system was developed in Italy and has rapidly asserted itself around the world. The system consists of the use of semi-prefabricated structural panels of reinforced concrete which are produced on site by spraying a fine-aggregate concrete on both sides of  pre-assembled lightweight panels of polystyrene foam with built-in steel mesh reinforcement which are produced in a factory.

The average skin thickness of the RCC are between 30 and 35mm in case of load bearing single panel walls , with a concrete strength of M-30, and is achieved by a mix of fine aggregate of 5mm down and cement, combined with a super plasticizer to ensure the proper workability.

Unlike conventional concrete panels these very strong yet lightweight panels do not require any shuttering or use of complicated steel reinforcement to be fabricated at site. The method of spraying the concrete ensures full compaction of the layers without use of conventional vibrators. However in the case of double panels with a filling of poured concrete, the panels are vibrated externally to ensure concrete free of cavities. Additional reinforcement is added where needed.


The whole structure, being monolithic, can absorb loads and stresses which would otherwise disintegrate most conventional structures with their multiplicity of joints, materials, and construction  types.

The system has been also used to build high-rise towers upto 20 floors high in many countries.In these cases. a special hollow panel is used for the load bearing members, which is filled with poured concrete after assembly, forming monolithic shear walls and structures capable of easily withstanding all  wind loads and earthquake-induced forces.

This is especially relevant as both Italy as well as Chile and other parts of Latin America where the system has been used extensively, are very active seismic areas.

The system may be used to rapidly construct any type of building, from low cost housing, to villas, apartments, as well as commercial and industrial buildings, and can be finished with most of the usual finishing materials.

Unlike the relatively insubstantial prefabricated  systems in use in the developed countries, the sheer simplicity and homogeneity of the monolithic concrete “sandwich” lends itself to use in developing countries, where it may be used by itself or in combination with more traditional forms of construction.The sheer speed and simplicity of construction also ensures that projects are completed in a fraction of the time required by traditional methods, especially in large-scale projects like mass housing, where the economy of the system is further increased by the “economy of scale”.

In the last 26 years, over 45,000 buildings have been successfully constructed world-wide using this system in countries as varied as Mexico,Chile, Italy, Portugal, U.K., Russia , Malaysia and Australia. Buildings constructed with this method survived a disastrous earthquake of 6.5 on the Richter scale in Guadeloupe which destroyed most of the neighboring structures.

We have completed various projects like Yatri Nivas at Kedarnath, Uttaranchal for Baba Kalikambliwala , Control Room of Carusal Ride at Nicco Park, Kolkata for Nicco Parks & Resorts Ltd., Two storied Management House at West Bengal Housing Board Lake View Project,Howrah for NPCC Ltd.Recently we are executing Bungalows named “Pavani” and “Ragini” at “Renaissance” project of Bengal Shrachi at Burdwan, West Bengal.
