Load-Bearing Masonry Systems for Foundations, Walls, and Building Structures
Jandris structural masonry products provide the backbone for load-bearing construction — from single-story foundations to multi-story reinforced masonry buildings. Our standard CMU line includes the full range of structural unit types: regular hollow, solid, bond beam, lintel, H-block, A-block, and specialty units in widths from 4” through 12”.
All load-bearing units conform to ASTM C-90. Available in normal weight, medium weight, and lightweight configurations to meet structural and fire rating requirements.
Regular 2-core and 3-core hollow units in all widths. Grout-fillable cores for vertical reinforcement. The workhorse of structural masonry.
Knock-out and solid bottom bond beam units for horizontal reinforcement courses. Available 6” through 12” widths.
U-shaped units for spanning openings. Steel reinforcement placed in grouted channel. Available in 6”, 8”, and 12” widths.
Solid units and percentage-solid units (58%, 62%, 75%) for fire rating and structural requirements. Up to 4-hour fire ratings.
Hi-R & Hi-R-H insulated units for energy code compliance and thermal performance. All architectural finishes are available with factory-installed Korfil insulation inserts, delivering tested R-Values up to R-18.

All architectural finishes are available with CarbonX technology, which lowers embodied carbon by reducing cement content and increasing CO₂ sequestration — by up to 50%, depending on the product.
