SPECIALISED MIXES
C20
This mix is used for footings in house construction, where the ground is soft or unstable. It can also be used as the slab foundation for the floors of houses and bungalows, also as a base for hard-standings and pathways.
C25
This level of mix may be required as slab foundation for houses or bungalows. It is also used when replacing or making good existing floors. It is also used in farming as a general yard mix, as it is strong enough to support light machinery and livestock usage.
C30/C35
These are structural concrete mixes for roadways, access to farms or anywhere where large, heavy vehicles require access on a regular basis. Durable mixes to withstand heavy wear and strong enough to withstand the ever-changing climate, continuous heavy rain, frosts, snow and prolonged dry periods.
C40/45
Used widely in farming, for the construction of slurry and silage pits. In this environment it is required to have the strength to contain tonnes of waste product and a strong mix (i.e. cement content) to withstand the acids and chemicals produced by the content, which often stays in the pits for long periods of time.
