What is Filler Slab Technology? 

Filler slab technology is an ingenious construction method where we replace a portion of concrete in a slab with lightweight, non-structural materials. These fillers, such as clay tiles or hollow bricks, are strategically placed between the structural grid of the slab. This approach reduces concrete usage without compromising the building's structural integrity.

Key Components of Filler Slab Construction:

• Structural grid (reinforced concrete)
• Lightweight filler materials (e.g., clay tiles, hollow bricks)
• Reduced concrete volume in tension zones
• Strategic placement for load distribution

Is filler slab construction cost-effective?

Yes, filler slab construction is generally cost-effective. At Ongrid Design, we've found that it can reduce slab construction costs by 15-20% compared to conventional methods. For a detailed cost analysis, check our home construction cost calculator.

What is the maximum span possible for a filler slab?

The maximum span of a filler slab depends on various factors, including the structural design and materials used. Typically, spans of up to 4-5 meters are common, but larger spans are possible with proper engineering. Always consult with a structural engineer for your specific project requirements.

What is the typical thickness of a filler slab?

Filler slab thickness can vary based on design requirements, but it's generally comparable to conventional slabs. Common thicknesses range from 110mm to 150mm for residential applications. The exact thickness will depend on the span, load, and filler materials used.

What is the difference between a fill slab and a filler slab?

A "fill slab" typically refers to a concrete slab poured over compacted fill material, often used in ground-floor construction. In contrast, a "filler slab" is a structural slab where part of the concrete is replaced with lighter materials to reduce weight and improve insulation.

Are filler slabs load-bearing?

Yes, filler slabs are designed to be load-bearing. The reinforced concrete ribs in the slab carry the structural loads, while the filler materials occupy the non-load-bearing areas. This design allows filler slabs to function effectively as structural elements in various home designs.

What is the basic methodology of filler slab construction?

The methodology involves:

1. Designing the structural grid
2. Placing reinforcement bars
3. Arranging filler materials (e.g., clay tiles) in the tension zone
4. Pouring concrete around the fillers
5. Curing the slab

This method requires skilled execution to ensure proper integration of fillers and concrete.

How thick should a standard concrete slab be?

Standard concrete slab thickness varies based on its purpose and load requirements. For residential floors, thicknesses typically range from 100mm to 150mm. However, in Pune's construction landscape, specific requirements may apply based on local building codes.

Is a 4-inch (100mm) slab thick enough for residential use?

A 4-inch slab can be sufficient for some residential applications, such as patios or lightly loaded interior floors. However, for main structural floors, especially in multi-story buildings, thicker slabs (5-6 inches or more) are often recommended. The appropriate thickness depends on various factors, including span, load, and local building codes.
