Knowing how to install geotextile correctly is just as important as selecting the right fabric. A common mistake is not providing enough geotextile overlap. As a rule of thumb, we recommend a minimum overlap of 300mm (12 inches) to ensure that water and fines cannot bypass the filter layer.

When it comes to geotextile seaming method, for most civil engineering applications, simple lapping is sufficient. However, for critical hydraulic applications, mechanical fasteners or sewing might be required. Always avoid leaving gaps.

Securing the fabric is another critical step. Geotextile staples vs pins is a debate often dictated by soil type. In soft soil, staples are faster, but in rocky terrain, large pins or rebar are necessary to prevent the fabric from shifting during backfilling.

For specific applications like geotextile under pavers or geotextile for pool decks, the installation process ensures that the base remains stable and prevents the pavers from sinking.
