Hydraulically pressed fly ash lime bricks to IS 12894 - straighter, stronger and lighter than clay.
Because they are pressed rather than fired, fly ash bricks come out dimensionally accurate, which means thinner mortar joints and noticeably less plaster. They are also stronger and absorb less water than the clay brick they replace, and no topsoil is burnt to make them.
Palletised and shrink-wrapped for export so breakage in transit stays low.
