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.

Concrete leaching chambers are used to leach out effluent from the septic tank into the ground. Concrete chambers are a long-lasting, reusable solution. They have been reliably used as leach fields for 50+ years.

Concrete Leach Field Chambers Advantages

Concrete leach field chambers have many advantages due to their durability, cost savings, quick installation and 40% leach field reduction in New Hampshire and Maine compared to a pipe and stone leach field.Concrete Leaching Chambers

  • Can be driven over (H-20 traffic-rated)
  • Enable a leach field size reduction up to 40% in New Hampshire & Maine, compared to pipe and stone design
  • Side seepage holes that enable liquid to be disbursed out of the sides as well as the bottom
  • Great for small lots where the leach field must be located in the driveway or in a parking lot
  • Leaching chambers install in minutes, saving contractors time
  • Concrete chambers can be reused

8x8 Chambers Install Faster and Reduce Project Costs by 33%

  • Must have a 4-inch perforated pipe run through them so the effluent can travel from one side of the chamber to the other.
  • Are easier to install than other sizes, and cost about 1/3 less than the same-size leach field bed that utilizes 4x8 chambers.

Concrete Leaching Chambers Sizes and Cost:

A.J. Foss precast concrete chambers are available in 5 sizes.

Leach Field Chambers

Concrete Leaching Chambers Provide 40% Smaller Leach Fields for Small Lots

4x8x13-inch tall 8-ft inlet side chambers can be used to lengthen an 8x8 septic chamber bed, enabling the designer to construct an appropriate bed size for each project. (This allows for extension of the leach field in 4-ft. sections instead of 8-ft sections. This means that the designer can extend from a 24 to a 28-ft wide bed, instead of needing to extend to 32-ft where space doesn’t allow.)

Other size septic chambers have a built-in precast pipe with slots on the side, for moving effluent from one side of the chamber to the other.
