The photo above is our 30′ wide put on the ground beside the blocks. You can also mount it on the blocks. Our packages most often come with a tarp cover for both ends. The assembly instructions give pointers on how to frame in the back. The finishing touch is one of our very economical roll up doors which typically keep out 90% of the weather.
These units can easily be mounted onto a beam which is secured to the top of one or more layers of big concrete blocks. It is important to have a seal between the beam and the block so that rain water will run to the outside.
An important area of consideration when mounting a structure to more than two rows of blocks, is the way that the wind load increases exponentially as the height increases. (i.e. 50% increase in height doubles the wind load). This is why we often go with reduced hoop spacing.
TARP vs. PLASTIC
The big difference is that with TARP you get extremely high tear resistance with good annual cover cost, and with PLASTIC you get slightly less life span but even less annual cover cost.
- Custom widths, heights & hoop spacing
- Roof vents & forced ventilation packages
- Various types & sizes of doors with end framing priced separately
- 8mm poly-carbonate sheeting for roof and/or ends
- Roll up sides for natural ventilation & reduced condensation
- Cross ties for added rigidity, support or other storage
