Under Fence Edging


SKU MM-HDPE-18-40-100

Tired of animals getting under your fence or have a neighbors weeds creeping into your yard? Our under fence edging is a great solution to provide a simple to install barrier that will help extend your fence even below the ground. It is made in the USA from 100% High-density polyethylene (HDPE). It is available in various sizes and thicknesses. The roll depths are 10", and 18” with thicknesses of 40 mil, 60 mil, or 80 mil (a mil is a 1,000th of an inch), roll lengths are all 100’. It can be cut down onsite to match the installation needs of your fence.

Installation is pretty straight forward. First, dig a trench at the base of the fence, drop the dig guard in the trench and then attach to the bottom of the fence with screws and washers (not included). Finally, backfill around the barrier.

This material is stocked in Kansas City, MO and typically ships within one business day.

Material Thickness:
40 mil = 3/64”
60 mil = 1/16”
80 mil = 5/64”


Note: Our HDPE plastic is only available in roll widths up to 60 inches.

Please note that we are unable to provide custom roll lengths.

    What Is High-Density Polyethylene Or HDPE?

    High-Density Polyethylene, or HDPE, is a thermoplastic polymer made from petroleum and is considered one of the most flexible plastics on the market. HDPE is used in a wide range of applications such as milk jugs, plastic bottles, shampoo bottles, bleach bottles, cutting boards, and piping. It has one of the highest tensile (pressure) strengths and large strength-to-density ratios ever. HDPE offers high-impact resistance and melting points as well. Although known for its use for food applications, it's found in many other applications including:

    Plastic surgery, especially skeletal and facial reconstruction
    Shoe molds
    3D printing filament
    Food and beverage containers
    Wood plastic composites
    Landscape products

    Are There Benefits Of Using HDPE Plastic?

    The industrial-grade HDPE has been approved by the FDA, NSF, and USDA. These sheets are constructed for low maintenance, safety, and longevity. Their textured surface holds food safely in place.

    Other Benefits

    Easy to melt down and mold

    One of the leading benefits of HDPE plastic is its incredible flexibility. HDPE excels in many categories including shaping and molding. Due to its high melting point, HDPE will remain stiff until very high temperatures are applied to the material. Once it reaches the melting point, the plastic can be quickly and easily molded for many different applications such as cutting boards, detergent bottles, containers for food storage, milk jugs, corrosion-resistant piping, geomembranes, plastic lumber, and the list goes on.

    Resists Corrosion

    HDPE resists mold, mildew, and rot, making it the perfect product for underground piping for delivering water and many marina applications such as docks, moorings, supplies, and boats. HDPE can be sterilized by boiling which is perfect for beverage and food containers. HDPE can tolerate most strong mineral acids and bases. It also has superb resistance to naturally occurring chemicals found in soil. The material is practically immune to most common chemicals, water, solvents, acids, detergents, and cleaning fluids.

    Large Strength-to-Density Ratio

    HDPE's density ranges from 0.93 to 0.97 g, even though the density of HDPE is only slightly higher than LDPE (low-density polyethylene). That said, when under the microscope, HDPE's linear structure means the material has little branching which gives it stronger intermolecular forces and pressure strength than LDPE. For this reason, a 60-gram HDPE container can safely carry over a gallon of liquid or around 8 pounds of weight.

    Is Recyclable

    If you consider how much plastic we use each day, one of the most important factors when choosing a material is its plastic recycling abilities. HDPE plastic is very easy to recycle which will keep non-biodegradable waste out of landfills and reduce plastic production by 50 percent! If you are looking for an effective environmentally responsible material, HDPE is the perfect choice for you.

    Why You Should Use HDPE Plastic

    HDPE can replace many heavier materials which will help companies and individuals go after sustainable and affordable manufacturing and project goals. Because of its high flexibility, rigid strength, and resistance to corrosion, HDPE is an excellent combination of strength and cost-efficiency. It's also environmentally friendly.

    According to some research, nonporous surfaces like plastic or glass are much easier to clean than wood and therefore a better choice for food safety. Wood is naturally porous and the tiny grooves in wooden cutting boards can capture bacteria. This is also why wooden cutting boards are not allowed in commercial kitchens! HDPE has become the choice of many companies and industries because of its quality characteristics.
