Tremix flooring is a specialized type of concrete flooring often used in basement construction due to its durability, dust-free finish, and ability to withstand heavy loads. The Tremix process involves a vacuum dewatering system that removes excess water from freshly laid concrete, resulting in a denser, stronger, and more wear-resistant surface.
In architectural applications for basements, this method is particularly favored for parking areas, storage rooms, and service zones where a hard, level surface is essential.
The process typically includes spreading a well-mixed concrete layer, leveling it with a screed, applying vacuum dewatering through a vacuum mat and pump, and then finishing the surface with power trowels for smoothness.
The final result is a monolithic, high-strength concrete floor that minimizes dust, reduces maintenance, and increases the lifespan of the basement flooring. Proper curing and joint cutting are crucial steps to avoid cracks and ensure long-term performance.

Tremix detail for basement in construction drawings refers to the technical representation of how a Tremix concrete floor is constructed in a basement setting. These drawings are crucial for ensuring the proper execution of the Tremix process on site and typically include cross-sectional and plan views with detailed notations.
Here’s a breakdown of what’s usually included in a Tremix detail drawing for a basement:
Typical Tremix Detail Components in a Drawing:
Sub-base Preparation:
- Well-compacted earth or moorum layer.
- Granular sub-base (GSB) or coarse sand (usually 100–150mm thick) for drainage and leveling.
- Anti-termite treatment if specified.
PCC (Plain Cement Concrete) Layer:
- Often a 100mm thick M10 grade concrete base.
- Acts as a leveling surface for the Tremix floor.
Tremix Flooring Layer:
- Concrete Layer: Generally 100–150mm thick, using M20–M25 grade concrete.
Surface Finishing:
- Mechanical vibration and screeding.
- Vacuum dewatering using Tremix equipment.
- Power troweling for smooth finish.
- Sometimes, dry shake hardeners are applied for surface strength.
Construction/Expansion Joints:
- Shown at regular intervals to prevent cracks.
- Detailed with joint fillers (e.g., bitumen board) and sealant.
Curing Notes:
- Wet curing methods like covering with wet hessian cloth for a minimum of 7 days.
Reinforcement (if applicable):
- May include welded wire mesh or steel bars depending on load conditions.
Slope Details:
- Indicated if drainage is required, typically 1:100 slope towards a drain or sump.
How It Appears on a Drawing:
- Section View showing all layers from sub-base to finished floor level.
- Material specifications and layer thicknesses marked clearly.
- Annotations for equipment used (like vacuum pump line).
- Dimensioning of joint spacing and slab panels.
- Drainage provisions or slope directions indicated with arrows.
