Salem’s initial target market was petroleum marketers in NC, as our founder oversaw 400% sales growth of a Exxon distributorship in the last eight years as its VP/GM.
Salem was one of the first two independent licensees of the Perma-Fill™ Inert Foam Process for in-place closure of petroleum USTs, with our first customer being the historic Mast Store in Valle Crucis, NC. From 1996 through 2006 Salem averaged closing 300+ residential USTs in-place each year.
We also oﬀer complete UST excavation and vacuum truck services for both residential and commercial USTs. All personnel involved with these two services have completed the OSHA 40-hour HAZWOPER course and are annually re-certified. If the client is worried about damage to ground foliage or grass, we place plywood under the mini-hoe to prevent such happening. Heating oil USTs are cut open and pressure washed to extract all sludges with the vac truck that can drip onto grass or shrubbery. Here are a few photos of recent excavations.
As most houses built before 1973 had heating oil USTs, many homeowners have no idea if a buried tank is still present on their property. Salem uses a surveyor-grade metal locator (Schonstedt Heli-Flux™) to identify such vessels. If a tank is discovered, our process of accessing the UST involves only disturbing a 2.5” diameter hole. Here are the tools we used to locate a tank in June 2017 and inspect it. Once inspected, we place a 3” test expansion plug in the hole and an orange survey flag next to it. Salem’s Senior Principal has done well over 5,000 metal detector residential UST surveys since 1989.
We can also provide the removal of out of service residential ASTs (Aboveground Storage Tanks) that are in crawl spaces or beside exterior foundation walls.
