Springs Clay Stock Brick NFX – 14 MPa | Quality Clay Bricks from Springs, Gauteng
The Springs Clay Stock Brick NFX – 14 MPa is a locally manufactured clay masonry brick suitable for residential, commercial and general building projects.
Manufactured in Springs, Gauteng, South Africa, these clay stock bricks provide a practical masonry solution for builders, contractors, developers and homeowners looking for reliable clay bricks for plastered wall construction and other suitable building applications.
Classified as NFX (Non-Facing Extra), these bricks are intended for general building applications where durability and structural suitability, rather than decorative appearance, determine material selection.
Independently Tested Clay Brick Strength
An important benefit of the Springs Clay Stock Brick is its independently verified compressive-strength performance.
In June 2026, Cermalab Materials Testing Laboratory conducted testing on 12 clay brick samples
The laboratory recorded:
- Average Compressive Strength: 30.4 MPa
- Lowest Individual Compressive Strength: 21.6 MPa
- Nominal Average Strength Requirement: 14 MPa
- Individual Strength Requirement: 10.5 MPa
- Average Water Absorption: 9.5%
The tested samples passed both the average and individual crushing-strength requirements assessed in accordance with SANS 227:2025.
The 30.4 MPa result represents the average of the 12 laboratory-tested samples and should not be interpreted as a guaranteed compressive strength for every brick supplied.
