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.

Quality Bulkhead Steps Construction + Professional Installation = Long-lasting Performance

Bulkhead steps are precast concrete staircases that allow for basement access. Since bulkhead installation requires skill and precision to ensure a watertight seal, very few precast concrete manufacturers offer bulkheads.

The experienced team at A.J. Foss provides quality bulkheads for clients throughout New Hampshire, Maine and Northern Massachusetts. Each set of A.J. Foss-crafted bulkhead steps is professionally installed to ensure maximum and long-lasting performance.

Available in industry standard sizes A.J. Foss-crafted bulkhead steps are available in standard industry types A, B, S, C, and D, to fit the appropriate elevation requirements. Our bulkhead steps are sized to fit any bulkhead doors manufactured by The Bilco Company or Gordon Corporation.

Properly Installed Bulkhead Steps Ensure Success

The bulkhead steps are fastened to your foundation using threaded rods, and then bolted with nuts and plates to secure them to the foundation. When the bolts are tightened, gaskets are placed between the pieces to create a seal that is watertight – as long as the appropriate grading and drainage requirements have been met. For example, roof drainage must be diverted away from the bulkhead opening; perimeter drainage must be properly installed; the top of the concrete casting must be at least 2 inches above grade; and the grade around the bulkhead must slope away from the building’s foundation.

Installation Requirements for Warranty of Bulkhead

  • Foundation sealer must be kept a minimum of 12-inches from bulkhead opening
  • Pour a minimum 11-1/2-inch step in bulkhead opening
  • Bulkhead opening must be kept a minimum 18-inches from a corner
  • Roof drainage must be diverted away from the bulkhead opening
  • Properly installed perimeter drainage to daylight
  • Backfill must be clean, well-compacted gravel
  • Top of concrete casting must be a minimum of 2-inches above grade. Grade around bulkhead must slope away from foundation.
