2.  Can be filled and fed out without additional equipment purchases

3.  Eliminates expensive maintenance of silo unloaders

4.  Feed cattle quickly from a Bunker Silo

5.  May be used for other types of storage

7.  Highest quality feed

Precast Systems bunker silos are 8 1/2' tall and come in lengths of 5' and 7 1/2'.  We have two styles, the "L-panel" and the "T-panel".  The L-panel are used for the outside walls and they are bolted together.  The T-panel, can be used for outside or divider wall, they are bolted together with recessed bolts so their would be no damage to your equipment.  We have radius corners at the top of our panels to eliminate the chance of tearing the plastic cover.

We recommend an 8" compacted gravel base under our walls; this could vary according to soil conditions.  The concrete or blacktop floor is poured up to the base of the panels after the walls are installed.  The bunker silos can also be set on your existing concrete or blacktop pad.  The precast concrete bunker silo walls are designed to be freestanding, (they don't need any outside supports).  They are also designed to take earth pressure from the outside so they can be installed into a hillside.

We recommend a slope of 1/2" to 2" slope on the Bunker site.  1" to 2" diameter screen rock or gravel under each wall approximately 8" thick covering a 4" tile line with a gravity outlet.

The reason for this is to keep the soil dry under the wall for better stability and to keep excess moisture and rain water out  of the feed so you will be able to achieve a higher quality of feed.
