Q. What are the advantages of IMPACT-CURB over pre-cast concrete curbs?
A. IMPACT-CURBs are environmentally friendly: they contain 100% recycled materials, and can themselves be recycled. Our curbs are made entirely from materials currently disposed of in landfills - so when you use an IMPACT-CURB you are helping the environment.
  • IMPACT-CURBs are made from non-organic materials and a plastic binder, so they can never rot or decay. There is no rebar inside an IMPACT-CURB to rust away. The expected life-span of IMPACT-CURBs is 75-100 years.
  • IMPACT-CURBs are completely unaffected by fresh water or salt water.
  • Unlike concrete bumper curbs, IMPACT-CURBs are non-porous, and are not affected by freeze/thaw cycles that cause concrete to spall and crack due to moisture.
  • IMPACT-CURBs are less prone to chipping and cracking damage from mechanical impact such as snow-plow blades or from being dropped. Concrete curbs are notoriously brittle and unforgiving in this regard. IMPACT-CURBs have unique shock absorbing capabilities unmatched in unreinforced or reinforced concrete curbs.
  • Rebar inside pre-case concrete curbs can create a hazardous protrusion when the concrete curb breaks or splits: these steel projections can represent a real liability hazard to people and vehicles. There is no rebar inside an IMPACT-CURB to pose a liability even if the IMPACT-CURBs is severely damaged by heavy equipment.
  • IMPACT-CURBs are less than 1/2 the weight of their concrete counterparts (72 pounds for IMPACT-CURB compared to 240 pounds for concrete). This means that they are easier to place and install than concrete curbs. In fact, IMPACT-CURB is easily lifted into place by two people! Furthermore, more curbs can be shipped on a given size of truck, so freight and handling costs are lower.
  • IMPACT-CURBs come pre-drilled with holes for hold-down pins.
Q. What kind of uses can be found for the parking curbs?
A. As their name implies, IMPACT-CURBs are primarily intended for parking lot bumper curbs. However, they can be used for a host of other applications:
  • Temporary or permanent roadway curbs
  • Walkway edging
  • Bicycle path edging
  • Traffic control bulbs
  • Site amenities
  • Shopping cart containment
Q. Can IMPACT-CURBs be submersed in water?
A. IMPACT-CURBs are ideal for wet environments. They can be submerged in water indefinitely without deteriorating.
Q. Is the IMPACT-CURB resistant to gasoline spills, oil and corrosive chemicals?
A. Yes. The curbs are made of materials which are resistant to a variety of chemicals including acids, bases, and many hydrocarbon solvents and liquids. They are also resistant to road salt and salt water.
Q. Does the curb absorb water?
A. IMPACT-CURBs do not absorb water. Water cannot penetrate into the material and decompose it, nor is it possible for repeated wet-dry cycles to lead to rot, spalling, splitting, or decay.
Q. Will freezing temperatures affect IMPACT-CURBs?
A. Temperatures below -40 deg. F will cause the curb to lose some of its flexibility. Other than that they are unaffected by extremes of cold or heat. Note that the flexural and compressive strengths of IMPACT-CURBs increase at cold temperature.
Q. How should IMPACT-CURBs be stored before I use them?
A. Although IMPACT-CURBs are much more crack resistant than conventional concrete curbs, we recommend that they be stacked as one would stack lumber - namely flat, one on top of another in a pile set on two curbs or boards running crosswise to the pile, set in about 18" from the ends of the curbs.
Q. If I need to cut an IMPACT-CURB, do I need any special equipment to cut them?
A. The curbs cut very well using a coarse destruct carbide-tipped circular saw blade (10 teeth or less). Wet cutting with diamond-tipped blades or a chain saw with a destruct blade works very well also. We have found that slower blade speeds give a better cut, due to the reduction in heat build-up n the material.

Note: Whenever you are handling and working with IMPACT-CURBs, always wear protective gloves. When cutting or drilling IMPACT-CURBs always wear approved protective eye-wear.
Q. Can I or should I paint IMPACT-CURBs?
A. It is easy to paint IMPACT-CURBs. There is no need to do this other than for appearance. The curb is not affected by the elements and therefore does not require any "special" treatment to achieve long life. Any good exterior-grade paint can be used. We recommend outdoor oil-based or alkyd paint - gloss or semi-gloss. Better-quality outdoor acrylic latex paints work, but results vary by paint manufacturer. For best results try a small sample and test for paint adhesion. Traffic line paint is specially formulated for this type of application and dries extremely quickly. With most paints, two coats are recommended for outdoor use. No particular surface preparation is required, other than ensuring the curb surface is clean and dry.
Q. If I cut an IMPACT-CURB, do I have to treat the cut ends?
A. No. The plastic used as a binder in the IMPACT-CURB is so well mixed that it encapsulates all the material in the curb. No preservatives or chemicals of any kind are necessary on cut surfaces to maintain IMPACT-CURB's resistance to rot, decay, or corrosive chemicals.
Q. Are the chips from cutting and drilling hazardous?
A. The material caused by drilling or cutting the curb is not hazardous. The material is inert to the environment and its surroundings.
Q. What color are IMPACT-CURBs?
A. The color of the curb is best described as "earthy brown" and is highly appropriate for natural looking landscape applications. No colorants are used in the manufacturing process.
Q. Do IMPACT-CURBs come in different colors?
A. The natural color of the IMPACT-CURB is an earth-brown color, and the color is consistent from IMPACT-CURB to IMPACT-CURB, and from batch to batch. Alternatively, you can paint IMPACT-CURBs easily yourself on-site.
Q. What is IMPACT-CURB made of and is it "environmentally friendly"?
A. IMPACT-CURB is made up of Auto Shredder Residue (ASR) and recycled plastic. While the auto shredder byproducts, being fibrous in nature, are used in IMPACT-CURB to provide strength, post-consumer and post-industrial plastics are used to bind the ASR material giving it solid physical form. Since the curb is made of 100% recycled material, if for any reason it is damaged or must be removed from service, it can be recycled and reprocessed back into a curb or some other product. IMPACT-CURB is environmentally friendly all around!
Q. What is ASR?
A. ASR stands for "Auto Shredder Residue" (also know in the industry as auto shredder "fluff", or auto shredder by-products). It is primarily comprised of the non-metallic materials used in manufacturing automobiles, such as car seat form, upholstery fibers, carpet fibers, paper, plastics, rubber, etc. Currently, ASR is land-filled: ours is the first commercially available product to use ASR in a manufactured product, thereby diverting ASR from the waste stream going into land-fill sites.
Q. How long will this material last? How resistant is it to ultraviolet rays and the weather?
A. IMPACT-CURB is a product that is very highly resistant to the elements and to moisture.

IMPACT-CURB is impervious to insect and ultraviolet damage, and will not splinter, rot or decompose in any fashion. During its life expectancy (~75 - 100 years) IMPACT-CURB will maintain its strength and its resistance against the elements.
Q. Is the curb brittle? What will happen if it is struck with a snow plow blade?
A. IMPACT-CURB has the ability to withstand considerable impact forces, even at cold temperatures. Unlike concrete, which is extremely brittle and easily damaged by impact, our IMPACT-CURBs are more flexible and forgiving in terms of resisting mechanical damage. IMPACT-CURB should not shatter or break, even if dropped from a considerable height.
