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

In this flooring necessary reinforcement provides depending 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.
