Split Face CMU

Jandris Split Face CMU’s are extremely durable, fire and mold resistant, and energy efficient due to high thermal mass. The raw materials used to produce most colors of our Split Face Blocks are local.

Jandris Split Face Blocks are fractured using a splitter exposing natural aggregates and creating a natural “rock-like” surface. They can be used for maintenance-free interior and/or exterior applications.

Variations of Split Face CMU
