Key Advantages

• The fastener drastically reduces your cost to maintain temporary stockpile covers without using heavy sandbags or gravel bags.
• 98% of the weight associated with sand or gravel bags has been eliminated, that also eliminates potential job related work injuries, such as back and leg injuries.
• The covers can be built on the ground, then drug over the pile with a excavator or other type of equipment using the fastener, once this is done the cover can be secured at the base.
• If you want to access your material, you can quickly take apart a seam or edge and move it out of the way without needing to move many heavy bags, then the cover can be easily modified and put back in place when the access to the material has been completed.

Quicker and Easier to Install

Fasteners are easier to install because they only weigh 7.5 ounces each, you also won't need to install as many. If you are installing them in a difficult location, you will only need to lift about 1% of the weight needed for sandbags. Since the weight is so much less compared to sandbags, you will eliminate the equipment needed to move thousands of pounds of sandbags or used tires around your project or from jobsite to jobsite. This will also reduce back breaking labor to install.

Stays in Place During Storms

The locks also greatly improves the performance of keeping the covers in place before and during storms. Traditional methods of keeping temporary covers in place tend to fail when they are needed most, right before or during a rain event due to the winds and the fact that a sand or gravel bags can only hold approximately 16 pounds despite weighing 40 pounds. This can cause expensive damage to a sites BMP compliance and or saturate you material adding more cost and time to a project and erosion concerns.
Symmloc only requires you to use a fraction of the weight required by sandbags of gravel bags, and you use less units and they can be used over and over, and transportation is easy, you can also add the benefit of having dry material during wet weather periods.

How many fasteners do I need for my stockpile?

40 fasteners that weigh only 20 pounds would replace 100 sandbags. To determine the exact amount of fasteners you need please ask your ALCO representative and we can do the calculations for you.

How much weight savings can I expect?

It depends on the size of your stockpile cover. For a very large cover the weight can be quite substantial considering a sandbag is about 40lbs versus a fastener which is only about 7.5ozs. The larger the stockpile the greater your expense in filling sandbags, moving them, and installing them.

How do they attach to the cover?

The fasteners require no special tools and hand tighten quickly. You only need the Base,
Cap, Connector, and a Knife for cutting the cover. See full directions here.

Are there installation directions?

Yes, you can view detailed installation directions here.

Are they reusable?

Yes, the fasteners are reusable and can be used on future covers you may need. Unlike sandbags, they are also quick to move and don't require extensive labor.

Are they quick to fasten to the stockpile cover?

Yes. This fastener can be installed in less than 60 seconds with a screw driver.

Does it have more holding force than a sandbag?

Yes. The fastener outperforms the holding ability of a sandbag, when you consider that a 40 lb. sandbag can only hold 16 lbs. Compare that to 110 lbs of holding force per fastener.
