Wienerberger had been pioneers in introducing the concept of large format Clay hollow blocks as a brand in India. Considering its growing popularity, many small-scale brick producers have started imitating the hollow pattern and selling an inferior variant of Clay hollow blocks in the name of Porotherm. Unfortunately, it has become easy for customers to be falsely misled by these manufacturers as they convince buyers that the blocks sold are indeed Porotherm Blocks. Some even went as far as putting the name Porotherm on their invoices.

Very recently one such producer of clay hollow blocks put a newspaper advertisement proclaiming to sell Porotherm blocks. The issue is none of the producers or suppliers of the duplicate/spurious blocks has the type of technology or knowledge base that exists with Wienerberger. When customers buy these blocks thinking to be Porotherm, they, unfortunately, end up paying for very inferior products which could be unsafe for use for building construction, even if they cost less than the original Porotherm Blocks.

Also, the blocks have optimum void pattern resulting in a high strength to weight ratio.
