Why Use This Calculator?

• Accurate Planning: Know the exact volume and weight of rubble to arrange transportation and disposal efficiently.
• Cost Management: Estimate costs for disposal services and rubble processing.
• Time-Saving: Avoid manual calculations and get reliable results instantly.

Things to Keep in Mind

Material Variations: Different materials generate varying amounts of rubble; ensure the correct primary material is selected.

Compaction Levels: Loose rubble occupies more space, while compacted rubble may reduce transportation requirements.

Demolition Method: Mechanical demolition typically produces finer debris, impacting volume and weight.

Mistakes to Avoid While Calculating Rubble Volume

Ignoring Material Type: Incorrect material selection can lead to inaccurate estimates.

Skipping Measurements: Precise dimensions are vital for reliable calculations; use a measuring tool or blueprint.

Overlooking Professional Assessment: For large-scale demolitions, consult with professionals to verify the results.

How to Calculate Rubble Quantity Manually

If you’d like to manually estimate the rubble volume and weight generated during a demolition, follow these steps:

1. Determine the Structure Volume

Use the formula for volume: Volume (m³) = Length × Width × Height

Example: For a structure measuring 22m × 22m × 22m: Volume = 22 × 22 × 22 = 10,648 m³

2. Account for Material Type

Different materials have different density and rubble factors. Here are approximate values:

• Concrete: 1.5 tons per m³
• Brick: 1.2 tons per m³
• Mixed Materials: 1.3 tons per m³

For concrete rubble: Weight = Volume × Material Density
Example: Weight = 10,648 × 1.5 = 15,972 tons

3. Adjust for Compaction

If rubble will be loose: Increase the volume by approximately 30% to account for air pockets. Loose Rubble Volume = Structure Volume × 1.3
Example: Loose Volume = 10,648 × 1.3 = 13,842 m³

If compacted, the volume may remain close to the original calculation.

4. Include Demolition Method Variations

Mechanical Demolition: Often produces smaller rubble pieces, making the weight more predictable.

Manual Demolition: May result in irregular rubble sizes, so volume estimates may vary.

5. Total Rubble Estimate

Combine the calculations for volume, material density, and compaction to get an approximate rubble weight and volume.

Example Calculation Recap

For a 22m × 22m × 22m concrete residential building:

• Volume: 10,648 m³
• Weight: 15,972 tons (without compaction adjustments)
• Loose Rubble Volume: 13,842 m³

These estimates provide a solid foundation for planning but should always be double-checked with a professional assessment.
