   • Is geotextile needed?

     “In most cases yes, for filtration and separation. Techdreno KC already comes with an integrated filter, eliminating the need for a separate geotextile.”

   • What is the difference between Techdreno and Techdreno DW?

     “Techdreno is a single-wall corrugated pipe for agricultural subsurface drainage in rolls up to 300 m. Techdreno DW has a double wall — corrugated exterior for mechanical strength and smooth interior for up to 30% higher flow, ideal for storm drainage and high-flow projects.”

   • How to size drainage for an agricultural area?

     “Agricultural drainage sizing depends on three variables: water table depth (typically 80 cm to 1.5 m), drain spacing (15 to 30 meters) and pipe diameter (DN65 to DN150). Techduto offers an online drainage calculator at /suporte/drenagem-calculos/.”

   • Does Techdreno work in heavy clay soils?

     “Yes. Clay soils benefit most from underground drainage. For heavy clay, use Techdreno KC with reduced drain spacing (15 to 20 m) and Bidim geotextile surrounding to prevent clogging.”
