Speed Bumps – Anchoring Options

When installing rubber speed bumps, there are several choices of anchoring that you may want to consider.  Typically for asphalt installation, a rebar spike is suggested.  While rebar can be purchased in a multitude of places, the manufacturer recommends a specific size & type.  These are 1/2” x 14” rebar spikes.  Spikes offered with the product are designed with a head that helps to hold the speed bump in place without the ability to lift like other options would allow.   Plus, the anchor point on each speed bump is countersunk to accommodate this spike head.  This protects both vehicle tires  as well as pedestrians.

For concrete installation, there are two anchoring options available.  These recycled rubber speed bumps are designed so that they can be removed when circumstances require it.  For this type of installation, lag bolts and shields are recommended.  Each lag bolt is 1/2” or 5/8” x 6”, plus a shield accompanies each lag at each anchor point.  This allows for easy removal when installed temporarily, or for winter storage.  Again, the anchor points are countersunk so that the anchoring bolt will never come in contact with vehicle tires.

The second option for anchoring on concrete is PL Premium construction grade adhesive.  This is used for a permanent installation – perhaps in a parking garage setting.  PL Premium adhesive is very strong, waterproof and low odor for safe installation.

Typically this is sold in a 10 oz tube that is applied with a caulking gun.  One speed bump section should use about 1 to 1-1/2 tubes of adhesive to ensure proper adhesion.  Surfaces, of course should be cleaned and free of debris prior to installation to provide optimum results.

Of course, proper measures should be taken to ensure weather conditions such as precipitation and freezing temperatures do not interfere with installation.  Also, when installing with adhesive, bonding time takes approximately 12 hours, so this must be considered before traffic flow is restored to the area of installation.

When selecting the best anchoring method for rubber speed bumps, it’s best to consider all variables of the installation to ensure you choose the best method for your circumstances.  Choosing the correct anchoring now, can save time and money for years and years to come.
