The core concretes used for housing and non-structural building applications are categorised under Gen designation.
GEN0 Concrete
What is GEN0 concrete?
Wet, lean mix concrete, most commonly known as GEN0 is a construction readymix used in commercial, DIY and general building projects.
GEN0 should only be used in external applications where it will be completely covered.
Typical Concrete strength: 7.5N/mm2 - 28 days
GEN0 concrete applications
- Foundations
- Fill and cavity material
- Kerb or ‘edge’ bedding
- Haunching and backing
- Blinding
GEN1 Concrete
What is 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.
Typical Concrete strength: 10N/mm2 - 28 days
GEN1 concrete applications
- DIY/domestic foundations for walls, shed bases, orangeries and conservatories
- Pad foundations
- Trench fill
- Foundations
- Internal floors – blinding
- Drainage
- Agricultural applications
- Fill and cavity material
- Kerb or ‘edge’ bedding
- Haunching and backing
GEN2 Concrete
What is GEN2 concrete?
GEN 2 is the ideal concrete mix for domestic, internal flooring intended to be carpeted, laminated or tiled.
GEN2 should only be used in external applications where it will be completely covered.
Typical Concrete strength: 15N/mm2 - 28 days
GEN2 Concrete Applications
- Trench fill
- Non reinforced concrete fill
- Strip footings
- DIY/domestic foundations for walls, shed bases, orangeries and conservatories
- Paving, steps or pathways
- Internal floors – blinding
GEN3 Concrete
What is GEN3 concrete?
Typically used for domestic applications and foundations GEN3 concrete is the perfect concrete for internal floor slabs where the intended finish will be carpet, tiles or laminate flooring.
GEN3 concrete should only be used in external applications where it will be completely covered.
Typical Concrete strength: 20N/mm2 - 28 days
GEN3 Concrete Applications
- Concrete fill
- Non reinforced strip footings
- Trench fill
- Foundations for garages (no embedded metal), extensions and home improvement projects
- Houses and walls
- Driveways
- Shed and workshop bases
- Patios
- Non reinforced bases for conservatories, orangeries, garages, sheds and greenhouses
