Indus Industrial Group supplies heavy-duty Perforated Corrugated HDPE Subsurface Drainage Pipes engineered across nominal diameters from DN100 to DN600 in ring stiffness classes SN4 and SN8 according to ASTM F405 and EN 13476-3. Featuring dual-wall construction with annular corrugated outer ribs and smooth slotted inner walls, these pipes provide rapid groundwater collection, landfill leachate extraction, and slope stabilization across Iraq. Supplied in coils (DN100–DN160) or 6.0m rigid lengths, they resist heavy overburden loads while preventing silt blinding.

Highway roadbed dewatering, municipal solid waste landfill leachate collection, agricultural sub-surface drainage, sports stadium turf dewatering, and airport runway safety strip drainage across Baghdad, Basra, Erbil, Kirkuk, and Anbar.
Perforated Corrugated HDPE Subsurface Drainage Pipes represent the modern engineering benchmark for large-scale earthwork dewatering, landfill leachate collection, and foundation drainage across Iraq. In massive infrastructure projects such as highway roadbeds, airport taxiways, and municipal waste management sites in Baghdad, Erbil, and Basra, managing high groundwater tables is critical to prevent soil liquefaction and roadbed failure. The dual-wall corrugated profile combines high ring stiffness with extreme flexibility, adapting to uneven trench beds and ground settlement without joint fracture.
The pipe incorporates precision-milled slot perforations located in the valleys of the exterior corrugations, protecting slot openings from direct aggregate shear during backfilling. With an internal smooth liner (Manning n=0.010), collected groundwater flows with minimal friction, ensuring continuous discharge even on flat regional slopes. Fabricated from virgin high-density polyethylene resin with minimum 2% carbon black, the pipe provides 100% chemical resistance to aggressive landfill leachates, industrial effluents, and corrosive subsoils spanning pH 1.0 to pH 14.0.
Staged at our Erbil Heavy Plant Yard, Baghdad Central Logistics Depot, and Basra Port Hub, Indus supplies perforated corrugated pipes pre-wrapped with certified non-woven geotextile filter sleeves or bare spigot/socket lengths, accompanied by full EN 10204 3.1 material test certificates.
The drainage slots are cut in the recessed valleys between the outer corrugation ridges. The high-stiffness ridges bridge the surrounding crushed stone backfill, keeping the slots open and free from direct stone contact during mechanical vibratory roller compaction.
Yes. PE100 polyethylene is chemically inert and completely impervious to aggressive chemical leachates, organic solvents, heavy metals, and high concentrations of hydrogen sulfide spanning pH 1.0 to pH 14.0.
Indus stages thousands of meters of DN100 to DN300 drainage coils and rigid lengths at our Erbil, Baghdad, and Basra hubs for immediate dispatch within 24 to 48 hours nationwide.
