Andrew J Foss has everything I need as an excavation contractor. Their service is prompt and their prices are very competitive.

Kevin and Barbara Fisher

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!!!!!!

Andrew Welch

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.

How many concrete leaching chambers do I need?

The number of leaching chambers a property requires correlates directly to site conditions including the bedroom count (which represents gallons-per-day of water used), and the percolation or “perc” rate (which represents the rate of absorbency into the ground) where the septic system is to be located. It also depends on whether an advanced treatment unit (ATU) will be used, or a conventional septic tank. 10 to 16 is a common range of required leaching chambers. Septic system designers refer to NH Table 1016-1 to determine the leach field bed size, based on the number of bedrooms and perc rate.
