What happens here

Once the gravel is in place, carefully fold the excess geotextile fabric over the top of the gravel. This action completely encloses the gravel and pipe, creating a 'burrito' that prevents soil and other debris from migrating into the drainage layer and clogging the system over time. After the fabric is wrapped, backfill the remainder of the trench with the excavated soil. This will conceal the drainage system and allow for surface landscaping, making it totally hidden. Ensure the soil is evenly distributed and compacted lightly to prevent settling, but avoid excessive compaction that could impede surface water infiltration.

Goal: Complete the drainage system by enclosing it and covering it with soil.

What they say

Hide

We got about 18 inches of stone on top of our pipe here. Now last step, got our non-woven fabric. We're going to fold this over like a burrito. Boom. Like this. Put another piece on top just to make sure it's totally separated from the soil and then put the dirt back on top. It's totally hidden. Good to go. Tucked into bed. Goodnight.
