I was looking for a new Presby septic system and I found Andrew J Foss. This company is great, awesome customer service, honest people, and really helpful. Thank you Andrew.
I have been a customer of AJ Foss for 18 years, they go out of there way to make my jobs successful. They are always prompt and courteous, I will continue to use them in the future
Andrew J Foss has everything I need as an excavation contractor. Their service is prompt and their prices are very competitive.
I called them to buy a septic tank and distribution box and they were very helpful and reasonably priced. I would buy from them again!!!!!!
I have had the opportunity to cross paths with AJ Foss many times over the past 10 years, and I have been consistently impressed with the quality of this organization. The number of contractors that trust AJ Foss for their precast concrete needs tells the story. Contractors don't want to insecurity, and the trust they put in AJ Foss speaks volumns. A quality family-run operation that has served southern NH for decades. If you are a contractor and you are NOT using AJ Foss, you owe it to yourself to check them out.

Plumbing that collects ground water in a concrete drywell is common in NH.  A.J. Foss-manufactured precast concrete drywells are reinforced with steel rebar and structural fiber for strength and durability. For home plumbing use, a 500-gallon drywell is produced with 120 liquid seepage knock outs. These drains or seepage knock outs can be removed as necessary. Our customers benefit from the drywells our team casts with one, two, three and four-inch combination low pressure Polylok© Pipe Seal. Our team can also pour them with a bottom.

Area drywells in service can be used to catch groundwater from a driveway, or from within a lawn. In New Hampshire, they can be used in a sanitary septic design. Their job is to enable the connection of a water treatment system (pipes from a water softener, for example) to the drywell instead of running it into a septic tank, which is not recommended. Some people connect plumbing from their washing machine and dish washer to a drywell.
