Lay Geotextile Fabric

What happens here

A layer of geotextile filter fabric is then carefully laid into the compacted footing trench, ensuring it covers the bottom and extends up the sides. This fabric serves multiple purposes: it prevents the foundation stone (which will be added next) from mixing with the native soil, allows water to drain through while retaining soil particles, and adds an extra layer of structural reinforcement to the wall system.

Goal: Install a permeable barrier to prevent soil migration and aid drainage.
