3" × 4" Hardcore is a large stone aggregate used for land drainage, soakaways and access-road construction.
3" × 4" Hardcore provides a coarse stone layer for applications requiring drainage voids, ground support or access preparation. The existing product information identifies land drainage, soakaways and access-road construction as its primary uses.
The larger stone format can help create a stable underlying layer when placed on a properly prepared site. For drainage and soakaway applications, performance depends on soil condition, installation depth, surrounding material and water flow. In wet Johor conditions, suitable compaction and drainage planning can help reduce settlement and surface deterioration.
