See this light brown soil? That's classic Calgary clay, and it can pose a REAL problem for your foundation...
❗ Clay-heavy soils expand when wet and shrink when dry.
⚠️ This can cause typical concrete foundations to shift, heave, or sink during our freeze/thaw cycle.
🤩 Which is exactly why we recommend Postech helical piles!
They resist soil expansion/shrinking - meaning your foundation WON'T go out-of-whack after a couple winters.
