Frequently used in foundations, domestic floor slabs, patios and paths, GEN 3 concrete mix has the highest cement content of the GEN concrete range. Each of GEN concretes has a designed strength with a minimum cement content and is quality assured to meet British/European standards.
What is a Gen 1 concrete mix?
GEN1 Concrete GEN1 is versatile mixed concrete widely used for general building and housing applications. Typically used for domestic, non-reinforced foundations, fills, haunching, kerb bedding; backing and drainage works. GEN1 should only be used in external applications where it will be completely covered.
What is a Gen 3 concrete mix?
GEN3. Gen 3 is commonly used for light duty domestic applications and foundations. It can be used to construct internal floor slabs that contain no embedded metal and will be covered by carpet, tiles or laminate flooring.
What is C20 concrete grade?
C20 Concrete Grade C20 or Gen 3 is rated at 20 Newton/28 day strength. This mixture can be used to form lightweight foundations and applications in residential projects. Typical uses for this grade of concrete are in the formation of internal floor slabs, driveways, garages, and sheds.
What does C stand for in concrete grade?
