What is the compressive strength of Old Mill thin brick?

Old Mill thin brick compressive strength - Exceeds 8,000 psi for durable veneer applications

Old Mill thin brick meets the requirements of ASTM C1088, the standard specification for thin veneer brick made from clay or shale. While ASTM C1088 does not define a minimum compressive strength, it does require testing per ASTM C67, which includes compressive strength among other performance criteria.

In practice, most clay brick products—including thin brick—exceed 3,000 psi, with many reaching 8,000 psi or higher, depending on raw materials and manufacturing methods. This aligns with data from the Brick Industry Association and field-tested performance across a range of building applications.

Old Mill’s thin brick is made from kiln-fired clay and performs on par with traditional full-bed clay brick. Though specific compressive strength values aren’t published for every product, you can expect high strength suitable for both interior and exterior adhered veneer use.
