Trimix flooring, also known as vacuum dewatered concrete (VDC) flooring, is a highly durable and wear-resistant type of flooring widely used in basements, industrial floors, parking areas, and warehouses.
In the context of a basement, Trimix flooring provides a strong, dust-free, and smooth surface that can withstand heavy loads and moisture conditions.
The process involves laying a concrete layer followed by vacuum dewatering to remove excess water, which increases the strength and reduces shrinkage cracks. After dewatering, surface finishing is done using power trowels and floats to achieve the desired smoothness.
Finally, a metallic or non-metallic floor hardener is applied to enhance the abrasion resistance. Trimix flooring is an ideal choice for basements due to its excellent durability, resistance to dampness, and low maintenance requirements.
Proper slope and drainage planning are also incorporated to avoid water stagnation, making it both a practical and long-lasting solution in architectural basement design.

Trimix flooring, also known as vacuum dewatered flooring, is a specialized concrete flooring technique used in construction to create a strong, durable, and dust-free surface.
In basement construction, where moisture control and load-bearing capacity are crucial, Trimix flooring is especially beneficial.
The process begins with the pouring of a concrete mix, typically of M20 or higher grade. Once the concrete is laid and leveled, a vacuum dewatering pump is used to extract excess water from the top layer. This significantly increases the strength and durability of the slab by reducing the water-cement ratio.
After dewatering, a floor hardener—either metallic or non-metallic—is spread over the surface to improve resistance to wear and abrasion.
The surface is then finished using mechanical trowels or power floats to achieve a smooth, compacted finish. The final step often includes curing for a minimum of 7 days to ensure the desired strength is achieved.
In basements, where conditions can be damp and prone to water seepage, Trimix flooring provides a long-lasting, maintenance-free surface that resists dust, cracks, and moisture. Proper slope and drainage must also be integrated into the floor design to direct water flow and prevent pooling.
