While concrete is strong and solid it expands and contracts, which can cause cracking and breaking up. Compared to rubber threshold ramps, this is especially true when attempting to bring a concrete edge to a thin layer, as when making a ramp. Concrete in thin applications is vulnerable to cracking, even when using plasticizers.
Concrete ramps or transitions often have to comply with the American with Disability Act, (ADA) where the edge of any ramp cannot be greater than a vertical ¼”. This is difficult to, especially in retro-fit applications when applying concrete on top of existing concrete, it often results in disaster with cracking and chipping due to expansion and contraction (as can be seen in the picture above).
The expense of saw-cutting and abrading is a way of remedying this problem; however, this can be costly and require building permits, setting and removal of forms, and the disposal of materials.
A quick and affordable remedy for this problem is to use a recycled rubber finishing edge part for the leading edge of the concrete ramp. Recycled rubber 
performs well; especially in inclement weather. It also offers a valuable visual cue to the pedestrian that there is an impending rise in the walkway. Moreover, the material properties in recycled rubber provide for an increased and superior Static Coefficient of Friction (SCOF) rating for the surface, which indicates the slipperiness of a particular surface.
Recycle rubber ramp products come in various sizes and heights. Rubber ramps or reducers are adhered with high grade silicone adhesive and have a long life cycle. When selecting a recycled rubber ramp product it is important to look for a high durometer rated product, (this indicates the density or hardness of the product). It is also important to specify no silicone on the product, as many manufacturers use silicone or similar product as a mold release agent. This can interfere with proper adhesion of the rubber to the substrate.
The use of recycled tires in conjunction with concrete makes for a fast and affordable fix that uses natural recycled resources that otherwise are headed for the landfill. More importantly, recycled rubber transitions serve a valuable and effective safe solution that does not freeze or crack in weather or with use. After all, ramp and transition projects should never result in a “breakup” between you and your valued customer.
