The performance of geotextile fabric is 50% product quality and 50% proper geotextile installation. Incorrect placement can render even a high-spec fabric ineffective. This guide outlines universal best practices for contractors and site crews.

1. Site Preparation: The subgrade must be smooth, free of sharp rocks, debris, and standing water. Any protrusions can cause stress points and tears. Proper compaction is also needed to prevent uneven settling that could strain the fabric.

2. Unrolling and Placement: Unroll the fabric directly onto the prepared surface. Avoid dragging it, as this can cause abrasion or puncture. For geotextile under gravel in a driveway, ensure the fabric covers the entire area plus extra for overlaps. The smooth side typically faces up (towards the aggregate) for optimal separation.

3. Overlapping and Seaming: Adjacent rolls must overlap sufficiently. For separation applications (e.g., driveway base), a 12-18 inch overlap is standard. For critical filtration or reinforcement applications, seams may need to be sewn or joined with adhesive tape. Never have "butt" joints without overlap.

4. Securing: Temporarily secure the fabric with stakes or sandbags, especially on slopes or in windy conditions, to prevent displacement during backfilling. Use care with stakes to avoid unnecessary holes.

5. Backfilling: This is the most critical phase. Drop the initial layer of backfill material (e.g., gravel, sand) from a low height. Use lightweight machinery initially to spread the material. Never allow tracked vehicles to drive directly on the exposed fabric. Once a protective cover of 6-12 inches is in place, standard equipment can be used.

Choosing a puncture resistant geotextile like our heavy duty options at HZGeotextile provides a safety margin during installation. By following these installation best practices, you ensure that your ground stabilization fabric functions as intended, saving time and money on corrective work.
