Large stone boulders are used in foundations, retaining walls, river protection and as raw material for crushing. A short overview of their main uses.
Stone boulders are large pieces of rock taken directly from the quarry face. They are one of the most basic construction materials and are used both as they are and as raw material for crushed products.
Main uses of boulders
- Foundations and plinth filling: boulders give a strong, stable base in soft or uneven ground.
- Retaining walls and pitching: dry or mortared stone walls protect slopes and embankments.
- River and canal protection: heavy stones reduce erosion around banks and bridge structures.
- Crushing: boulders are fed into crushers to produce chips, aggregates and stone dust.
What to look for
Good boulders are hard, sound and free from cracks or weathered layers. The required size depends on the work: smaller pieces are easier to handle for walls, while larger stones suit protection work.
Always follow the size and quality requirements given by the project engineer or the relevant specification.
Planning delivery access at site is just as important: make sure trucks can reach the unloading point safely and that there is enough space to stack the material.
