Sand backfilling is one of the most volume-intensive activities on any UAE construction site. Foundations, service trenches, road sub-bases, and landscaping all require careful quantity calculation. Order too little and you delay the project. Order too much and you pay for excess haulage and disposal.
Our Sand Backfill and Compaction Calculator gives UAE contractors instant results for net compacted volume, loose volume to order, number of truck loads, and number of compaction layers required.
How to Use This Calculator
- Enter the length, width, and depth of your backfill area in metres
- Select the material type — desert sand, washed sand, or granular fill
- Choose your compaction layer thickness — 200mm is standard
- Click Calculate for volume, loose order quantity, truck loads, and compaction passes
🇦🇪 UAE Tip: UAE soil contains high sulfate concentrations in many areas. Never use excavated site soil as backfill near structures without soil testing. Use clean washed desert sand or imported granular fill for structural backfill. Always test compaction using a sand cone test or nuclear densometer — minimum 95% MDD is required for most UAE structural backfill specifications.
The Formula Explained
Net Volume = Length x Width x Depth. Loose Volume = Net Volume x Bulking Factor (1.25 to 1.35). Truck Loads = Loose Volume divided by 10m3 which is the standard UAE tipper truck capacity.
Frequently Asked Questions
What is the compaction standard for UAE backfill?
Structural backfill: minimum 95% MDD per BS 1377 or ASTM D698. Road sub-base: 98% MDD. Landscaping: 90% MDD is typically sufficient. Always test and document results.
How thick per compaction layer in UAE?
Maximum 200mm per layer for vibrating plate compactors. Maximum 300mm for vibrating rollers. Thicker layers result in poor compaction at the bottom of the layer.
What truck size delivers sand in UAE?
Standard UAE tipper trucks carry 10 cubic metres loose. Some larger trucks carry 14 to 16 cubic metres. Always confirm the load size with your supplier before ordering.
