We have an oval bunker with perforated walls, do we need to run top air intake pipes over the top of the pile?
We do recommend that 4”- 6”top pipe be installed. The fans will only draw air from the top of the wall system down to the aeration tubes leaving the top part of the pile deprived of any airflow. You want to provide a balanced air flow throughout the whole pile to maintain product quality.
Our round pile seems to always “heat up” around the center or “core” of the pile. What can be done?
Unfortunately, during the filling process the “fines or bee’s wings” tend to build up in this area. This build-up can significantly minimize the amount of air flow that can pass through this area causing higher temperatures. Consider our VeraVent® Air Intakes. These vents can be installed near the center of the pile allowing for direct airflow to this problem area. Studies have shown that when VeraVent® is installed, temperatures lowered to acceptable ranges within 2-3 days of use. Should temperatures rise again, the VeraVent® design allows the user to open & close the vent as needed, helping to maintain temperature levels within the core.
When filling our bunker, some areas do not get to the top of the wall. Will this create a problem down the road?
We recommend filling these areas in before covering. Leaving these “voids” around the top of the wall can create several problems. One problem is these areas will “pool” the water runoff from the cover creating a “stress point” on the cover. Excessive water build up can pull the cover away from the wall, allowing this buildup to enter the pile. Secondly, high winds can enter these areas causing the cover to start to “float” which can also cause the cover to rip away from the base seal which can lead to significant damage to the cover.
Our ground pile always seems to have a considerable amount of damage around the aeration duct. How can we reduce this damage?
Consider laying down some of the covering material that is 12’ wide by whatever the length of the perforated pipe is and place the aeration pipe on the material. This will prevent the pipe from having direct contact with the ground. Depending on the makeup of your pad, aeration fans can pull moisture as far as 10’-12’ out of the ground. Placing this barrier under the pipe will limit the amount of moisture that can be pulled around the pipe, reducing product damage.
Are your Alternate Daily Covers (ADC’s) impermeable?
JMI Covers manufacturers ADC’s using both permeable and impermeable material. JMI also has both materials available in Fire Retardant versions.
Are there stock sizes and configurations?
JMI manufacturers ADC’s according to each customer’s specific needs. Size, material choice, reinforcement and deployment options are all available for each individual customer. We do have standard designs available for automatic deployment equipment.
What is the typical lead time?
Lead times vary depending on the time of year. We ask that our customers allow 4 – 6 weeks from order placement to delivery of their custom tarps.
