40 MM Jelly Stones: The Heavy-Duty Foundation Specialist

While 12 MM and 20 MM aggregates are used for detailed structural work, 40 MM Jelly Stones are used in "Mass Concreting" and ground preparation. Their large size provides a solid, incompressible base that can withstand extreme pressure from the structure above.

Key Product Features

• Exceptional Load Bearing: Due to their large volume and mass, these stones distribute weight over a wider area, making them indispensable for heavy foundational layers.
• High Impact & Crushing Resistance: Sourced from hard igneous blue metal, our 40 MM stones possess high mechanical strength, ensuring they do not pulverize under heavy machinery or structural loads.
• Economical Volumetric Fill: Using 40 MM stones in mass pours reduces the overall amount of cement paste required to fill the voids compared to using only smaller aggregates, making large-scale projects more cost-effective.
• Natural Drainage Properties: The large gaps between 40 MM stones allow for excellent water permeability, making them ideal for sub-surface drainage and preventing waterlogging around foundations.
• Purity & Cleanliness: Our aggregates are machine-screened to ensure they are free from organic matter, clay, and silt, ensuring a high-quality bond when used in Lean Concrete.

Primary Applications

• PCC (Plain Cement Concrete): The most common use for 40 MM stones is in the base layer (bedding) of foundations, where reinforcement is not required.
• Mass Concreting: Ideal for large-scale pours such as dam walls, heavy machinery foundations, and thick raft slabs.
• Sub-Base for Roads: Used as a primary "base course" layer in highway and driveway construction to provide a stable, non-shifting foundation for the asphalt or concrete above.
• Railway Ballast: Due to their toughness and size, they are used to support railway sleepers and provide necessary drainage and load distribution.
• Ground Levelling: Used in "soling" or bottom-filling for waterlogged sites or areas with soft soil to create a firm working platform.
