A. Jandris Block, a family owned business established in 1920, saw it’s infancy during the Great Depression. Traditional values practiced out of necessity have evolved into present day resource conservation and efficiency. Our manufacturing plant has taken several steps to reduce oil, water, and energy consumption.
Sustainable Manufacturing
Improved Air quality
We have improved our manufacturing facility air quality by installing a washable fabric duct system. This system clears dust and circulates air evenly thought-out the plant, resulting in improved efficiency of our HVAC system.
Oil Reduction
Our curing kilns use the process of low temperature hydration and hydro-injection. This process utilizes the natural heat given off by the curing concrete, and has enabled us to cut our kiln fossil fuel consumption by approximately 50%. Excess heat is circulated through the plant to help warm the facility in the winter, reducing our dependence on heating fuels.
Thermal Mass Cooling System
Cool air from the warehouse area is circulated throughout the manufacturing facility, acting as a substitute for air conditioning. The warehouse naturally remains cool during the summer due to the high thermal mass of the CMU structure and the CMU’s stored within.
Cement Reduction
As innovators in manufacturing, we have been able to reduce the amount of Portland cement powder used in CMU production.
Compaction Advantage – Compression and vibration performed during the manufacturing process increases the strength of the concrete, reducing the overall amount of Portland cement powder needed. Because of this process, Jandris CMU’s generally contain 40% less Portland cement than poured concrete.
Specialized Upgrades – Incremental upgrades to our manufacturing process have enabled us to use less cement while keeping our strengths consistent. Using less cement lowers our environmental impacts. The positive impacts of our upgrades are reflected in our Environmental Product Declarations
Water Conservation
We use an advanced closed-loop water cooling system throughout our finishing facility. Within the system, concrete particles are separated and removed before water reuse.
Materials Reuse & Recycling
We take our pallets off of the jobsite, repair and reuse them. Customers pay a deposit as incentive for return.
All plastic wrap used for safety during shipping is recyclable.
Left over and damaged blocks (culls) are crushed and used by local industries for road base.
