New Haven CT – Concrete Barrier Anchoring

On The Job With KELKEN

New Haven, CT – When working in a high speed high traffic area, like I-95, taking the proper safety precautions to protect roadside workers is vitally important. Those concrete safety barriers that we frequently see lining the sides of major highways often serve as the first and last line of defense for contractors. To be effective those barriers need to be held securely in place, an easy enough job to do with standard concrete anchoring materials. The problem is that most concrete anchoring products are designed to be permanent and the barriers are a temporary safety precaution that need to be moved frequently as the workers move on to new sections of highway. Uprooting and moving concrete barriers that are held in place with a permanent concrete anchoring system is a very time consuming, labor intensive process. This makes a versatile high strength removable anchoring system for the barriers an absolute must for highway construction projects. Enter Kelken with their polyester resin anchoring material Keligrout and their custom sized removable Kelianchors.

In late 2009 Florida based construction company Walsh Group (www.walshgroup.com) was awarded the contract to repair the Pearl Harbor Memorial Bridge in New Haven, CT. Heavy construction began in February and is expected to last through 2012. The concrete deck on both the north and south lanes needs to be replaced, and repairs are needed on the superstructure and bearings of the entire bridge. Much of the work is being completed at night, and in segments, reaffirming the need for an anchoring system that would securely hold the safety barriers in place, yet allow them to be moved to the next work zone protection area with minimal removal time. Kelken’s chemical anchoring system provided just the solution they were looking for.

For securing the barriers anchors were drilled into 3” of asphalt until they hit concrete. They were then drilled an additional 7” into the deck. The holes were filled with Keligrout and the anchors coated with Kelislip, a Teflon solution allowing the anchors to be turned out of the Keligrout when needed. Using this system the barriers were able to provide work zone protection while the deck on the northbound side was being reconstructed. When this portion of the project was complete the anchors were simply spun out of their holes, thanks to the Keligrout, and reused on the next work zone protection area.

Not only does Kelken’s removable chemical anchoring system save time and money but it also eliminates waste by reusing the same anchors. Thanks to the versatility and extremely high pullout values of Kelken’s chemical anchoring products they have been used by DOTs all over the country and by several branches of the US Military giving them widespread notoriety.

Kelislip™ is a paint-like product that allows Kelianchors to be made removable. The anchors are treated with this TEFLON solution. The cured resin will not adhere to the anchor, only to the surrounding concrete. (More Info)

Removable Kelianchors™ are single/double header with deep threads that allow as much pullout strength as permanent anchors. Kelken manufacturers a variety of different anchors. They are available in any material, diameter, length or finish, for use with Kelken chemical anchoring products. Keligrout can withstand temperatures of up to 200 degrees Fahrenheit and down to -40 below Fahrenheit. Keligrout can also be used in underwater applications or in rainy weather making it the perfect choice for all applications, especially those where the anchoring materials will be exposed to temperature extremes year round.
