Naval Air Engineering Station Lakehurst, the former name of the Lakehurst part of Joint Base McGuire-Dix-Lakehurst, is a United States Air Force-managed Joint Base located nearby Trenton, New Jersey. It is the northeast’s largest naval aviation center.

It is most renowned for being the site of the Hindenburg disaster on 6 May 1937 in which the German passenger airship LZ 129 Hindenburg caught fire and was destroyed during its attempt to dock at the base, ending the airship era.  NAS Lakehurst is truly a veritable nugget of historical wealth.  The dirigible hangars from 80 years ago are still there.

During a routine inspection at the base, it was discovered that a number of  reinforced concrete pipe (RCP) runs used to carry stormwater had deteriorated and were no longer hydraulically or structurally sufficient. The pipes needed to be replaced or repaired. The main challenges for this particular project were the extremely tight constraints and the narrow construction activity windows.

The failing RCP runs were accessible only through the manhole structures unless the typical and costly open trench replacement method was used.

After a discussion with Contech Engineered Solutions, the facilities engineer decided to reline the existing RCP with  SPR™ PE, a polyethylene structural liner reinforced with steel.  This would enable them to access the RCP through the manholes directly whereby they could then wind the structural liner directly into the host pipe.

Using SPR™ PE negated the normal logistical and space requirements of open cut methods, and it kept an important area of the base functional.
