All-Bin Flex Skirt

Never again deal with water seeping under your bins, rotting your grain and rusting your bins.

Simple, easy-to-figure cost is listed below.

Grain bins expand and contract with heat and cold, fighting concrete base and sealant, continually damaging any type of sealant applied. Tar, epoxy and foam are expensive fixes that don’t last. Inevitable cracks appear in these temporary “band-aids,” even acting as reservoirs to store the water, rot the grain and rust the bottom of the bin rings. Sealants are an expensive, labor intensive, counter-productive  and temporary fix.

Beginning in the Pacific Northwest and now stretching across the country, our Flex Skirt is attached to bins as small as 15′ in diameter up to diameters as large as 106′! Our customers no longer deal with rotten grain and rusty bottom rings!

Bin owners now have a solution to this never-before solved problem. The Flex Skirt provides a dry zone. The skirt moves with the bin and the dry zone remains stationary and independent, protecting your grain and base rings at all times.

Even bin owners with elevated floors utilize the Flex Skirt so their bin bottoms and interior spaces always stay dry and rust free. The Flex Skirt keeps water outside the bin and dry zone. Bugs no longer have wet grain fines to flock to and multiply inside on the concrete floor. Without the rotting wet grain fines, bins are much less likely to corrode and rust.

The All-Bin Flex Skirt is attached to the bin and slides over the concrete base and essential protective dam as the bin expands and contracts, providing constant protection. Our protective dam does not contact the moving bin, thereby maintaining dry conditions at the bin base at all times.


This was our first installation. Most concrete bin bases from bin wall to concrete edge are larger than 4″ which makes skirting to the edge prohibitively expensive. Our protective foam dam (under the skirt) keeps water from flowing back to and under the bin wall.

Your price will include:

    • Flex skirting, corrugated and double seamed on top and bottom edges
    • Fasteners
    • Splash Guard-seamed on top and bottom edges, sectioned underneath to fit any bin
    • Splash Guard sealant
    • Applicator molding guide
    • Foam for protective dam
    • Instructions
    • On-call tech help as needed
    • If I have a narrow concrete apron around my bin, do I need your foam dam?
      No, concrete bin-to-concrete edges that measure 4″ or less do not need the foam dam. The skirt can be placed over the edge giving water an exit off the Flex-Skirt. The foam cost is not a significant part of the Flex-Skirt cost.

      Do I need the protective foam dam on bin bottom-to-concrete edges measuring more than 4″?
      Yes. If not, water will flow to your bin like it did in the old days! Our protective dam foam-lock process will insure your bin will stay dry.

      Does the wind affect the Flex-Skirt?
      No, we have never had a problem with wind moving the skirt. There is a natural tension and wind deflection inherent in the Flex Skirt that keeps it pushed against the bin at all times.

      Do rodents nest under the skirt?
      We have never had a report of rodents nesting and multiplying under the Flex-Skirt. If a problem should occur, it is simple to place poison or traps under the Flex-Skirt or in the ends.

      * What do I get with the All-Bin Flex Skirt?
      Moveit provides all components required and instructions needed to install our Flex Skirt on your bins. Our patented Foam Dam under the Flex Skirt has no contact or conflict with the bin and therefore isn’t susceptible to cracks and seal damage. The Flex Skirt, Splash Guard and Fan Channel are galvanized sheet metal and attach to the bin with Stainless Steel self-tapping screws which are provided.

      * How long does it take if I install the Flex Skirt myself?
      Flex Skirt installation time varies by size and configuration of bin — Two workers can usually install a Flex Skirt package on a 34’ bin without outside stiffeners in less than 4 hours. Outside stiffener bins take slightly longer. Large operators put the installation up for bid or hire a crew.

      * Do I need tools to install the Flex Skirt?
      Yes, a few tools are needed—cordless drill, 5/16” (or 3/8″ nut driver for over .177″ bin wall thickness), cinch or tie-down strap for skirt installation.  A small 1″-2″ brush or dauber for sealant above splash guard. Depending on the bin, an angle grinder & cutoff (skinny) wheel may be needed for alterations along with a 4″ masonry blade (for a small channel cut in concrete around bin to seal foam on). Old tar and sealants must be removed 2”-3” and outward from bin wall. Circular wire brush/electric drill works best. Concrete should be clean and bare

      * How is the Flex Skirt shipped?
      For small orders, Fed Ex Ground. Larger orders shipped LTL (Less Than truckLoad) motor freight. Each order will receive individual rolls of approximately 50’ corrugated Flex Skirt combined for preferred handling plus extra skirt lengths to fill your order.

      * Do I have to have anything special at my location to receive order?
      For LTL (Less Than Truckload) orders, a forklift or loading dock must be at destination location or freight company has additional charges.

      Determine Cost: Bin diameter + 1 foot, multiply by 3.14 = Linear feet. $7 per foot. Includes freight. Add $20 per fan transition. Stiffener plates: add $3 per stiffener.

      Rodent control/food grade inspection doors are available, not expensive & easily installed. We have found this step not usually necessary but can be easily added later if desired.

This is a no-brainer! It’s a permanent solution for what used to be a constant problem.
It’s such a big problem I had a neighbor that poured about 6 inches of concrete in the bottom of his bins. He said the hardest part was framing the fan strips in the floor and then dealing with the sweep auger each year. No more water but it was a lot more effort and dollars than tar. This skirt is the perfect fix!
This is a godsend to keep water out of the corn. I’ve tried many things over the years but the water always finds a way to get in. Thanks!
