Stockpile Covers

Wadham Energy's 8 Acre 60 foot high Stockpile Covers

Stockpile Cover

This stockpile cover is currently being used st the Wadham Energy Site. It provides an effective way to cover large stockpiles in windy areas. This Stockpile covers a 8 acre site and is approximately 60 feet high. The cover has greatly reduced maintenance cost while greatly improving the performance and integrity of the cover. This has also removed the need for the placement off thousands of sandbags that needed to be placed over the top of the pile and connected to miles of ropes. This method reduces the the previous need of placing thousands of pounds of weight up steep slopes and reducing the backbreaking labor needed in the past.

This Cover is approximately 57,000 SF in a windy open field in the Central Valley of California on a Granite Construction Project. See this testimonial to see how this Temporary Cover worked for them.

Less is More Larger covers that are superior in windy conditions, compared sandbags, using 60% fewer fasteners and 1% of the weight.

Safer Because Symmloc Fasteners weigh less than 1/2 a pound and you use fewer of them, this makes them easier to install, especially on steep or difficult areas and also reduce work related injuries related to carrying heavy bags on uneven surfaces.


Efficient Fewer units plus less weight, means you will accomplish more with less. You can move them around with pickups and by hand due to their light weight, so you won't need trucks, tractors and back breaking labor to secure your covers.

Transportation This Pickup contains 400 Symmloc Fasteners that only weigh 200 pounds, they can replace 1,200 sandbags weighing 42,000 pounds. This is why they are easy to transport, deploy, install and they are reusable.
