In 2009, the company started delivering high quality clay building materials from its state-of-the-art production facility in Kunigal, Karnataka. MONNANDA APPAIAH, MANAGING DIRECTOR, WIENERBERGER INDIA, responded to queries from CONSTRUCTION OPPORTUNITIES


Briefly talk of the role played by your firm in India’s green building space?

Construction and development is going to be inevitable and further will grow more and more, in this scenario the best contribution is to offer green products and adhere to green processes. Porotherm Clay Bricks are truly green in nature right from sourcing of the raw material till end use where in it facilitates large savings in terms of steel and concrete, energy consumption, even the labor - savings are achieved. Hence to summarise in a nut shell the product offering Porotherm plays a vital role in supporting the developmental need of the hour but by green means and measures adopted. Our state of the art factory is one of most energy conserving, green factories right from excavating silted dry water tanks to use of raw materials from industry by products to efficient recycling of heat energy. The whole process makes us produce a green building product like Porotherm.


Tell us about the specific services or products offered by your firm? Also tell us about your manufacturing units – their locations and capacities?

Wienerberger has been in existence since 1819, close to two centuries, with its Head Office in Vienna, Austria and over 200 factories across the world in 30 countries. Since 2009 the company expanded its presence in Asia and chose Bengaluru for its first Asian footprint.

We have a state of the art production facility in Kunigal Industrial town, 75 km from Bengaluru, producing high quality clay walling materials rated by the Indian Green Building Council and GRIHA (TERI). The facility has a capacity of producing over 450 tons of bricks a day and runs 365 days a year, 24/7. We manufacture world class superior quality clay based walling solutions – Porotherm Smart Bricks which include:

  • Porotherm HP for infill masonry
  • Porotherm VP for load bearing applications
  • PorothermThermobrick for exceptional thermal insulation
  • Porotherm HP grinded with Dryfix solution for superior masonry

Both Koramic Roof Solutions and Aspect Clay Façade Tiles are supplied by our European facilities.



What are the areas of opportunities you are looking to capitalise on?

Currently we are focused on expanding our production facility to service the growing needs of the market and also provide innovative value added solutions for our customers to improve masonry and construction practices.


Could you name the key green building projects with which you have been associated and tell us about the specific benefits accruing to those projects and your clients? Also name few of key clients from the infrastructure/construction domain?

Since 2009, we have supplied to over 5000 projects across South India and the majority of our clients have been driven by the concepts of sustainability and green building and many of them have also been awarded Leed Ratings. Some of the Leed rated projects include Indian School Of Business (Hyderabad), PUMA Showroom, CMH Road, Bengaluru, Geojit BNP Paribas’ Corporate Office in Kochi, to name a few.



In terms of scope of work in various projects in India – including design, raw materials, and process – could you tell us of the critical challenges faced while developing sustainable structures?

On a planet with finite natural resources and an ever-growing built environment, engineers of the future must consider the environmental, economic, and social sustainability of structural design. The definition of sustainable structures is interpreted differently as per the project and the person in charge. However, on a broader perspective, the critical challenges lie in having one evaluating system on measuring levels of sustainability, awareness of the market in terms of sustainable products and executing the project in lines with selected guidelines on sustainable path. If these three points are evaluated in detail the broad perspective would be very clear for any project to be executed as per plan with most efficient usage of design, raw materials and process. The positive effect of a green building product can be experienced in the entire project life cycle of the building. From our experience, for example, we have seen significant reduction in electricity consumption in independent houses using Porotherm wall solutions due to effective thermal insulation throughout the year.



To what extent is cost a deterrent in pushing green technologies and products?

Green technologies and products are perceived to be high in cost but if evaluated and the whole aspect of the product/technology offering is been well understood and practically applied then it is never a deterrent, as real green products and technologies offer various long and short term benefits to each stake holder, like in the case of Porotherm Clay Bricks,

  • Execution Benefit:
    (Stakeholder: contractor and labour)
    Lighter faster construction, less wastages, precise wall construction
  • Builder Benefit:
    Saves in terms of steel and conwcrete, faster construction, saves largely on input cost of construction
  • End User/Occupier:
    Provides healthy living environment, regulates temperature, saves on air conditioning energy, low maintenance etc.



What are the new products you expect to launch in 2016-17?

We have plans to launch POROTHERM Bricks in Grinded version along with Dry Fix System which is a dry mortar/glue…the system provides absolute sand / mortar free construction – something that will be of huge benefit to the construction industry considering water/sand shortages; Also we are in the process of launching new profiles of clay façade & roofing solutions as well…



What according to you will emerge as the key growth drivers for this sector? What is the company’s growth agenda for 2016-17?
The growth rate projected for the Indian building and construction industry coupled with our commitment towards addressing climate change issues. It is imperative for the industry to move towards sustainable construction practices. Hence the potential is vast for Wienerberger and we will continue to strive towards offering greener solutions for the future and at the same time bringing meaningful difference to improve industry practices.
