Build Hub supplies hardcore and crushed stone sub-base in Zanzibar for build-up beneath slabs, paving, hardstanding, driveways and access works. The required material and layer build-up should follow the project design and site conditions.
Hardcore is coarse fill used to build up a stable layer beneath ground slabs, paving, hardstanding, driveways and access roads. It is different from concrete aggregate and from fine crusher dust.
Material choice, layer thickness and compaction should reflect the ground conditions and project detail. Where a specification exists, send it with the enquiry.
Hardcore is priced on request because material requirement, quantity, location, access and delivery arrangement vary by project. Build Hub does not publish an invented fixed rate; the written quotation confirms the material, volume and delivery basis.
Hardcore can be delivered across served areas of Unguja, including Stone Town and Urban West, Nungwi and Kendwa, Paje and Jambiani, Kiwengwa, Matemwe, Fumba and Chukwani.
Truck size, load quantity, route distance, turning space and ground conditions affect delivery planning. Share a map pin and access notes before dispatch.

No. Hardcore is a coarser build-up material; concrete aggregate is selected for concrete or other specified uses; crusher dust is a fine crushed material used for levelling and selected paving applications.
