Concrete Masonry Unit (CMU) Product Information Sheet:
The following applies to all standard concrete masonry units regardless of size,
weight class and texture.
Manufacturer: Central Arizona Block Co: Inc. 6030 S. Mann Ave, Tucson AZ. 85756
Quality Control Assurance: all product shall meet the requirements of ASTM C90 for concrete masonry units. Products are submitted to an accredited certified testing lab on a regular basis to insure compliance to ASTM C90. Certification letters
of such compliance along with applicable testing is available, upon request for commercial projects.
Leed / recycling: Many of our products utilize pre and post-consumer “waste” in their manufacture, keeping this material out
of our landfills and saving natural resources. Custom ratios are available on a job per job basis.
Product Weight Classes: Products are available in 3 weight classes, most common is Normal (HW) and Mid Weight (MW).
A light weight is also available (LW).
Product Sizes: Nominal (includes standard mortar joint of 3/8”) anything between 2” to 12” in width, 2” to 8” in height, length
up to 24”.
Product Textures: Smooth, Spilt-face, Raked Face (Founders Finish), Shot Blast, Ground and Polished are available.
Product Colors: Almost infinite array of pigment combinations is available. In addition, on block with exposed aggregate (non-smooth), additional color accents are possible through use of colored aggregates such as red and black cinder,
marble and white cement.
Fire Resistance: Masonry Block has excellent fire resistance and most fire ratings use an equivalent thickness method
per NCMA “National Concrete Masonry Association” -TEK 7. By varying the width, voids and block fill a desired fire rating is attained.
Water Resistance: Masonry is a somewhat porous product. An internal water repellent “IWR” is available at additional cost. Whenever a water repellent CMU is required by design, the mortar should also contain an IWR. For best results,
for added protection, the whole masonry section should be sealed again after construction. This helps seal the mortar
joints, which is the most common cause of weep through a masonry wall. “Raked mortar joints” are very likely to allow
water inside a wall on standard shell thickness block and should be for interior use only. If exterior use is desired consult
your design professional and our technical team to see if offset core units that have a thicker front shell, might provide
for sufficient mortar thickness for exterior use. Do not lay block in rain or wet block, it greatly increase likelihood of
efflorescence.
Handling: Do not stack any pallet, with product less than 6” high, on another pallet, ground stack only. Ground must be
free of rocks an reasonably level. Do not stack any other block more than 2 pallets high, and it must be in a safe and
flat location. Cover block if rain is expected. Specialty block comes covered, only uncover what is to be used.
Quality Control: CABCO takes the utmost pride and care in the production of all our masonry products. All products manufactured by CABCO undergo production methods and quality control standards and meet or exceeds ASTM C90 Standards. As such our breakage / defect allowance is set at 4%, vs ASTM C90's 5%. While every effort is made during manufacturing, and we use multiple inspection checks, to produce the best and most consistent block possible, units not meeting standard project standards cosmetically (usually color variation) do occur, either through manufacturing, curing, handling, aggregate color variation, color dye lots, transport or job site conditions. Transportation chipping of corners is not counted as a product defect due to: 1) the sorry condition of most of our roads, some chipping will occur and is beyond our control. 2) Damage caused by improper Job-site handling is also beyond our control. Handling: On site chipping can be minimized by lifting not dragging product off pallets, careful staging, ect. Do not stack any pallet, with product less than 6” high, on another pallet, ground stack only. Ground must be free of rocks an reasonably level. Do not stack any other block more than 2 pallets high, and it must be in a safe and flat location. Cover block if rain is expected. Specialty block comes covered, only uncover what is to be used.
Acceptance: DO NOT INSTALL ANY PRODUCT DEEMED DEFECTIVE - once in the wall you have accepted it as satisfactory.
Warranty / Customer Satisfaction: Since the mason handles every block, any block deemed not merchantable by the customer, that exceeds 4% of total, that product should be set aside and CABCO shall be notified.
When CABCO is advised of an issue, we will inspect such product in question:
A - if we agree upon inspection there is an quality issue, we will either replace such units (subject to it being on pallets) with the best suited satisfactory replacement then available at CABCO's cost, including transportation (product only) or issue a refund of the product in question, at CABCO's sole option. Product in question must be neatly stacked on CABCO pallets by the customer.
B - If CABCO upon inspection at it's sole discretion, deems the product was merchantable but damaged after delivery due to improper handling, on the job-site, whether by customer or any other party, no warranty will apply.
Again, once the product is placed in a wall, it is considered merchantable, accepted by customer and is the installers sole
responsibility!!!
Liability under this warranty is limited to the replacement or refund of the product in question only, at CABCO's SOLE discretion. No lost labor, lost time, project delays, consequential or incidental damages are applicable for any reason.
