Trimix flooring is a special type of flooring, generally used for industrial purposes. It has a better wear and tear property. It is mostly done in the industrial sector, where rigid surface is necessary for machine foundation, light load cranes and light weight carrier vehicles. Generally, the concrete mix used for trimix is 1:1:5:3 (1 cement: 1.5 sand and: 3 stone aggregates), mostly rich mix of 1:1:2 is preferred for better wear and tear.

In this flooring necessary reinforcement depends upon the thickness of the flooring, whereas the thickness of concrete is decided from 100 to 200 mm over PCC (1:4:8) and well-prepared stone soling base ranging from 230 to 300 mm. In industrial flooring PCC base should be kept up to 100 mm and same as concrete 150 mm, may be satisfactory for heavy duty areas such as warehouses, garage, and machine shop.
