C35 concrete is one of the most versatile structural mixes used across UK construction. The “C” stands for compressive strength and the ‘35’ tells you it reaches 35 megapascals (MPa or N/mm²) at 28 days.
That combination of strength and workability makes C35 a go-to grade for everything from domestic driveways to reinforced commercial foundations.
What is C35 concrete used for?
- Reinforced foundations — extensions, garages, commercial builds
- Domestic driveways — particularly where heavy vehicles will park
- External paved surfaces — patios, hardstanding, paths
- Agricultural yards — farm hardstandings, livestock yards
- Light commercial slabs — workshops, warehouse mezzanines
- Retaining walls — domestic and small commercial
C35 concrete mix design
A typical C35 mix contains:
- ~340–380 kg of cement per m³
- Aggregates (sand + 20mm stone)
- Water at a water-cement ratio of approximately 0.45–0.50
- Air entrainment for external freeze-thaw resistance
- Optional: plasticiser for improved workability, fibres for crack control
With volumetric concrete, this mix is produced fresh on-site to spec every time.

FAQs
What is C35 concrete used for?+
C35 is widely used for reinforced foundations, external paved surfaces, agricultural yards, light commercial slabs and driveways where a stronger mix is required than standard C25/C30.
How much does C35 concrete cost per m³?+
C35 concrete in Yorkshire is typically £110–£130 per cubic metre ex-VAT (2026 pricing). Same Day Concrete supplies C35 at £120 per m³ ex-VAT plus £60 delivery.
What is the difference between C30 and C35 concrete?+
C30 has a compressive strength of 30 MPa — fine for standard driveways and garage floors. C35 is 35 MPa — stronger and more durable, used where heavier loads or reinforcement are expected.
Is C35 the same as RC35?+
Not exactly. C35 refers to compressive strength only. RC35 is a designated reinforced-concrete grade with the same strength but includes durability requirements for specific exposure classes.
