Gravel is an essential component of reinforced concrete. Prices have slightly decreased early 2026 thanks to increased quarry production capacity in the Casa-Settat region.
About 0.8 m3 of gravel per 1 m3 of B25 concrete. For a 15 m3 slab, you need ~12 m3 gravel.
Gravel 5/15 for thin slabs and delicate éléments. Gravel 15/25 for foundations, columns and beams. All-in 0/40 is for earthworks and backfill.
Group your orders with sand (same quarry). From 20 m3, ask for volume discount. Negotiate free delivery and verify actual volume at réception.
Crushed gravel (angular) is standard for concrete — better adherence with cement. Rounded gravel (river) is not recommended for reinforced concrete but can be used for drainage and décoration.
Yes, recycled gravel (démolition) can be used for backfill and sub-layers. It's 30-40% cheaper. For structural concrete, only use certified new gravel.
