Build Phase 2 – Weeping tile

We used approx 9 yards of gravel and 4 yards of clay fill for the bioshelter foundation. One wheelbarrow at a time, makes for long days and strong arms. We chose clay fill because of its comapactability around the structure. For other parts of the yard I wouldn’t recommend using clay, it does not encourage microorganisms.


After installing the Frost Protected Shallow Foundation we put a 2″ layer of gravel, then placed  weeping tile the perimeter of the structure, ensuring the water is directed away from the  bioshelter.  A weeping tile is a porous pipe, also called a drain or perimeter tile or corrugated drain pipe, used for underground water collection or discharge. You can purchase the weeping tile with or without a sock. The sock prevents soil and debris from clogging the pipe. We used a three way connector to tie the weeping tile together at the corner. Four yards of clay fill were used to cover the weeping tile.


The bioshelter took the site of my previous vegetable garden. I had spent 5 years composting and creating a rich soil that I wanted to  protect from the job site. Apparently the soil was a perfect protection for a rat to have her babies. YUK! I try to encourage critters in our yard, but rats I do not want! They must have been only a day or two old. They made for a quick, delicious treat for my friends chickens.
