- Our crew piped concrete into forms, and so placed rebar every 24 inches to strengthen the bail betwixt the footings and the foundation.
The Formwork Is Set up

- Snap ties agree the two opposing form halves together.

- The remnants of the snap ties tin exist seen on the concrete wall.
Waterproofing and Insulation

- Next, two-inch Owens Corning rigid insulation is attached to the foundation, providing an of import improver to the complete insulation plan with an R-value of 10.
Lay the Drain Tile
- For extra protection from water intrusion in our basement, we put in drain tile. This perforated plastic piping is laid around the foundation to direct water abroad.
- Starting time, we laid Form five gravel along the perimeter of the footings. Then we set the bleed tile on the gravel. Water will now period toward the septic drain field and away from the basement.
