Gravel-sand mixture C7 is a graded natural aggregate blend for foundation and base applications in construction and road building. C-class mixtures combine sand and gravel fractions in controlled proportions, producing a material that compacts into a dense, load-distributing layer beneath foundations, floor slabs, footpaths and pavement structures.
Grade C7 is among the standard specifications called up in civil works documentation, which makes it a routine, repeat-purchase commodity for contractors rather than a specialty item. Buyers value consistency of grading above all: predictable fraction composition means predictable compaction behavior and fewer failed density tests on site.
The product targets general contractors, road builders, concrete plants and building material traders. With pricing from $6.00 per unit and a minimum order of 500, the mixture is supplied in bulk volumes aligned with real project consumption, where a single foundation can absorb hundreds of tonnes of base material.
