By far the deepest foundation we’ve ever dug for a patio. #hardscape #paverpatio #construction

What happens here

This project outlines the construction of an exceptionally deep patio foundation, necessitated by new construction on recently backfilled or "virgin" soil. Unlike standard patio foundations that are typically only one foot deep, this method involves excavating to an approximate depth of three feet to reach stable, undisturbed subgrade. This deep excavation and subsequent compaction of the virgin subgrade is crucial to prevent future settling and sinking of the patio, ensuring long-term stability for the stone or concrete surface built upon it.
