Indus Industrial Group supplies heavy-duty Perforated and Slotted uPVC Subsoil Drainage Pipes engineered across nominal diameters from DN100 to DN315 in ring stiffness classes SN4 and SN8 according to DIN 1187 and BS 4962 standards. Designed specifically for groundwater lowering, retaining wall drainage, highway sub-base dewatering, and agricultural sub-surface salinity leaching across Iraq, these pipes feature precision-cut longitudinal slots or circular perforations configured in 180-degree or 360-degree arrays. Manufactured from virgin unplasticized PVC, they resist aggressive subsoil groundwater, sulfates, and fine silt blockage.

Highway and railway sub-base drainage, building foundation groundwater dewatering, retaining wall weep drainage, agricultural soil salinity leaching, and airport runway subsurface dewatering across Baghdad, Basra, Erbil, Najaf, and Karbala.
Perforated uPVC Subsoil Drainage Pipes represent the primary civil engineering solution for sub-base moisture control, structural foundation dewatering, and agricultural salinity mitigation across Iraq. In the alluvial plains of central and southern Iraq (Baghdad, Basra, Wasit, Babylon), high water tables laden with dissolved gypsum and sodium chloride cause structural subsidence, asphalt pavement breakup, and agricultural land salinization. Indus slotted uPVC pipes collect and convey subterranean leachate rapidly away from road embankments and civil foundations without structural soil loss.
The pipe wall is precision-machined with calibrated slot widths (typically 1.2mm to 2.5mm) that prevent aggregate clogging while ensuring maximum water intake rates (inflow area exceeding 50 cm²/m). Available in partially perforated (180° for collecting surface infiltration while conveying bottom flow) or fully perforated (360° for total groundwater drawdown) configurations, the solid-wall uPVC profile provides ring stiffness classes SN4 and SN8 per ISO 9969, safely bearing continuous highway wheel loads without slot pinching or diametric collapse.
The push-fit rubber ring or solvent socket joints provide fast trench alignment in wet ground conditions. Backed by extensive warehouse inventory at our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies slotted pipes alongside non-woven geotextile filter fabrics (150–300 g/m²) and EN 10204 3.1 material test certificates for rapid tender deployment.
For highway under-drainage, 180° or 220° crown slotting is standard. Perforations on the upper half collect percolating water, while the smooth solid invert at the bottom conveys water away without letting it seep back into the road sub-base.
Indus supplies perforated uPVC pipes wrapped in needle-punched non-woven polypropylene geotextile filter jackets (150 to 200 g/m²). The geotextile retains fine sand particles while allowing groundwater to enter freely.
Class SN8 (≥8 kN/m²) is mandatory beneath active highway carriageways and airport runways, safely absorbing heavy multi-axle truck loads (AASHTO H-20 / HS-25) without diametric slot compression.
