Designation: GEN 0

Strength: 6/8 newtons after 28 days


  • Domestic foundations
  • Edgings, kerb bedding, haunching, backing

C10 (16_1)

Flexible mixture that can be used in both domestic and commercial industries, but mainly for non-structural uses.

Designation: GEN 1

Strength: 10 newtons after 28 days


  • Strip footings
  • Garden walls
  • Trench fill and pad foundations
  • Drainage works
  • Oversite below suspended slabs
  • Binding house floors

C15 (15_1)

Used for domestic (DIY) and commercial projects.

Designation: GEN 2

Strength: 15 newtons after 28 days


  • Foundations
  • Floors, especially on occasions when no permanent finish will be added e.g tiles or carpet
  • House/garage floors that have no embedded metal
  • Paving for steps and pathways

C20 (12_1/ST1)

Mainly used in the domestic market, but also in the commercial.

Designations: GEN 3, RC

Strength: 20 newtons after 28 days


  • Lightweight domestic applications and foundations
  • Driveways, garage, shed bases
  • Internal floor slabs that have no embedded metal

C25 (11_1/ST 2)

Useful for a range of domestic and commercial projects.

Designations: FND, RC

Strength: 25 newtons after 28 days


  • Footings for unstable/soft ground
  • Foundations
  • Groundwork
  • Mass concrete fill, reinforced fill and trench fill
  • Kerbing
  • Patios

C30 (9_1/ST 3)

PAV 1 designated concrete are air-entrained concrete mixes. The air-entrainment process purposefully forms tiny air bubbles within the concrete, which boosts both its durability and its ability to withstand freeze-thaw cycles. The presence of bubbles also increases the workability of the concrete whilst in a plastic state.

Designations: PAV 1, RC, FND

Strength: 30 newtons after 28 days


Suitable for use in many industries, including domestic, agricultural, and commercial.

  • External parking
  • Access routes for heavy vehicles
  • Reinforced foundations

C35 (7_1/ST 4)

Designations: PAV 2, RC

Strength: 35 newtons after 28 days


  • Heavy-duty external paving and slabbing
  • Reinforced bases for commercial and agricultural buildings
  • Can withstand rubber-tyred vehicles, loading and scraping
  • House/garage floors contained embedded metal

C40 (5_1/ST 5)

High-strength, high-performing concrete ideal for many industries, including industrial, agricultural and civil.

Designations: RC

Strength: 40 newtons after 28 days


  • Ironworks
  • Manholes, lamp-posts, road signs
  • Structural beams and foundations
  • Slurry and silage pits for farms
  • Chemically-harsh environments
