We offer a lag bolt mounting system consisting of a lag bolt, anchor, and washer to anchor into pavement or concrete. There are 4 anchor holes for our MLSB product line in each speed bump. For temporary situations, you can just lay them down or moor them in place with our GRK’s RSS™ Rugged Structural Screw. For our RK Series speed bump and speed humps, there are 2 anchor holes for each 24” long section.

Yes, our MLSB traffic calming product line, with a 24” rebar spike or gravel earth screw can be purchased from RubberForm. These rebar spikes and earth screws should be checked periodically to make sure they have not crept up to create a hazard.

For our MLSB2.5 we use 2 embedded AASHTO approved yellow reflectors. On our MLSB3 and MLSB4, we use a high visibility reflective yellow tape. For our RK series speed bumps and speed humps we use a special-formulated safety yellow paint with reflective glass beads.

Yes, if you need to remove them for the winter, just unbolt or unscrew the bolts/screws and store for the season. Seal the holes with Eco-Bond so water, dirt and rocks do not get lodged in the holes.

Our line of MLSB speed bumps come in 36” long pieces that connect with a dovetail, allowing you to create the length you need. Our RK series speed bump and speed humps come in 24” sections that link together with a special dual-flange connector which also allows you to create any length you need.

We have custom-formulated the right material for hard traffic over many years of use. We use masticated recycled rubber, which is harder and more durable than virgin clay-filled rubber or crumb rubber and poly compounds.

Our speed bumps and speed humps are in stock and can usually be shipped out the following day. Larger orders (greater than 100 units) may take a little longer – please provide us enough time to manufacture and let us know when you will need delivery.

RubberForm is one of the only true U.S. manufacturers of rubber speed bumps and speed humps. They are made from domestically sourced scrap tire rubber, manufactured, and assembled in the U.S. We believe that this is the only way to maintain our high standard of quality control.
