Tremix Flooring Solutions

Tremix flooring is a specialized type of flooring primarily utilized in industrial settings due to its superior wear and tear properties. This flooring solution is particularly beneficial where a rigid surface is essential for machine foundations, light load carrier vehicles, and lightweight cranes. Typically, the concrete mix used for the Tremix flooring system follows a ratio of 1:1:5:3 (1 part cement, 1.5 parts sand, 3 parts stone aggregates), while a richer mix of 1:1:2 is often preferred for enhanced durability. The required reinforcement depends on the flooring thickness, which is typically set between 100 to 200 mm over a prepared PCC base (1:4:8) and stone soling ranging from 230 to 300 mm. For robust industrial flooring solutions, a PCC base of 100 mm alongside a concrete thickness of 150 mm may be adequate for heavy-duty areas like warehouses, garages, and machine shops.

**TOOLS AND MATERIALS REQUIRED**

All necessary mason tools and tackles should be available on site. Additionally, some specialized tools are required, such as:

1. Floater machine

2. Tremix skin

3. Double beam screed vibrator  

Materials must adhere to specifications, including the 1:1:2 mix and floor hardener.

**FLOORING PROCEDURES**

To successfully implement flooring procedures, begin by preparing the sub-base through watering and ramming, ensuring no loose materials are left behind. Level the surface and install a 230 mm to 300 mm stone soling layer, with a 150 mm thick layer that must be properly compacted. Maintaining the appropriate floor slope during the PCC work, which is laid above the stone soling, is vital; the thickness of the PCC should be maintained at 100 mm. The Tremix flooring system should be completed in panels, where each panel measures 3.5 meters. Adequate reinforcement bars should be layered, ensuring a concrete cover of 50 mm (subject to standard variations).

Utilizing vacuum de-watering machines is advantageous as they effectively remove excess water from the top layer of wet concrete without displacing the cement or sand particles. This process should occur promptly after concreting, ramming, or vibrating with a screed vibrator, followed by the initial round of troweling while the concrete remains fresh. This method not only enhances the concrete's strength but also improves the floor's abrasion resistance. Using a hardener during the finishing process with the floater machine is highly recommended to further increase durability and minimize shrinkage cracks. Furthermore, to mitigate shrinkage and enhance the floor's wear resistance, small quantities of hardener and polyurethane fibers should be integrated into the concrete mix as specified by the manufacturers.

Casting concrete flooring in panels is crucial to prevent shrinkage cracks and function as expansion joints. Although it can be a slow and time-consuming process, especially over large areas, laying concrete in panels without construction joints allows for effective management. After the concrete has set for 7 to 10 days but is not yet fully hardened, panel joints can be cut using a cutting saw. The resulting gap should then be filled with poly sulfide or sealants.
