Perforated uPVC Pipes Manufacturer in Saudi Arabia
4B Factory manufactures perforated and slotted uPVC pipes from 75 mm to 500 mm at our Al-Kharj Industrial District facility — produced with custom perforation patterns, hole diameters from 5 mm to 13 mm, and 1 to 6 rows of perforation. Engineered for sub-soil drainage, agricultural drainage, water well screens, landfill leachate collection, and infrastructure dewatering across Saudi Arabia.

Saudi-Made Perforated Pipes for Drainage, Wells & Leachate Systems
Perforated uPVC pipes collect water from surrounding soil or contain liquid for controlled flow — used for sub-soil drainage under landscapes and roads, agricultural drainage in farmland, well casings and screens in water extraction, and leachate collection in landfills. Generic catalogue patterns rarely match site hydraulics or filter design.
4B Factory perforated pipes are fabricated to your project specification — hole diameter, row count, longitudinal and angular pitch, and pattern type (straight or staggered) all customised to the site conditions, soil type, and water table behaviour. No standard catalogue limitations.

Sizes, Perforation Geometry & Standards
Our perforated pipes cover the diameter and pattern range Saudi agricultural, infrastructure, and water resources buyers need — fabricated from our extruded uPVC pipe stock with full traceability.

Straight vs Staggered Perforation — Which Pattern?
Perforation geometry directly affects inflow rate, structural strength, and filtration behaviour. Match the pattern type to the application — drainage, well screen, or leachate.
Straight Row Perforation
Holes arranged in aligned longitudinal rows along the pipe length. Provides maximum inflow rate for a given hole count and is easier to align with filter sock material. Typically used for sub-soil drainage, agricultural drainage, and leachate collection where inflow capacity matters most.
Staggered Row Perforation
Holes arranged in offset rows around the pipe circumference. Distributes structural load more evenly and provides higher hoop strength at the same open area. Preferred for deep well screens, deep-burial drainage, and applications where the pipe is under high external pressure.
Hole diameter (5–13 mm), longitudinal pitch (30–200 mm), and angular pitch (40°/80°/120°) are all selected based on the design soil type, groundwater behaviour, and filter sock specification. Our technical team can advise on perforation geometry from your drainage calculation or well design. For unperforated parent sewer/drainage pipes, see our Sewer & Drain Pipes page.
Applications Across Saudi Arabia
Our perforated pipes are installed across the Kingdom in every project type that needs controlled water collection — from villa landscapes to landfill cells.
Sub-Soil Drainage
Sub-grade drainage under roads, parking, sports fields, and large landscaped areas.
Agricultural Drainage
Field drainage for Qassim, Al-Kharj, and Saudi agricultural belt — controls water table for dates, vegetables, and fodder.
Water Well Casings
Well casing and screen for water extraction wells, observation wells, and dewatering installations.
Highway Sub-Drainage
Below-pavement drainage for highways, expressways, and major road infrastructure.
Landfill Leachate Collection
Leachate collection pipes within landfill cells and at base liner systems.
Landscape & Golf Drainage
Fairway, green, and large-compound landscape drainage where water table control is critical.
Infrastructure Dewatering
Construction-phase dewatering for deep excavations, basements, and tunnel works.
Vision 2030 Landscapes
Sub-soil drainage for Diriyah, Qiddiya, King Salman Park, and major landscape mega-projects.
Bulk Supply for Drainage, Agriculture & Water Resource Projects
4B Factory routinely supplies large quantities of perforated uPVC pipes for major Saudi drainage and water resource programmes. Our team works from your drainage calculation or well design — issuing formal quotations with full compliance documentation, custom perforation specifications, and project-scheduled delivery.
Frequently Asked Questions
Common questions from contractors, agricultural buyers, drainage consultants, and water resource engineers sourcing perforated uPVC pipes in Saudi Arabia.
At minimum: pipe diameter, hole diameter, number of rows, longitudinal pitch (mm between holes along length), pattern type (straight or staggered), and application (drainage, well screen, leachate). For complex designs, a sketch or drainage calculation is ideal. Our technical team will confirm geometry and issue a quotation.
Perforated = circular holes drilled or punched into the pipe wall. Slotted = elongated slots cut into the pipe wall. Perforated patterns suit most drainage and well screen applications. Slotted patterns suit fine-soil filtration where a longer, narrower opening behaves better with filter sock material. Both are produced at 4B Factory.
Diameters from 75 mm to 500 mm in our standard range, in 6 m lengths (3 m and other lengths to order). Larger diameters can be produced where parent pipe stock allows — contact our technical team for project-specific sizes.
Yes — we produce well casings and well screens to DIN 4925 part I, II, and III standards. Specify the well design, expected drawdown, and filter pack details, and we’ll match the screen geometry.
Yes. Leachate collection typically uses larger hole diameters (10–13 mm), higher row counts, and straight patterns to maximise inflow. We fabricate to the cell design and base-liner system specification.
Typical ranges: hole diameter 5–8 mm, longitudinal pitch 50–150 mm, straight 2-row pattern. But the right combination depends on soil type (clay, sandy loam, sand), water table behaviour, and drainage spacing. Our team can advise from your soil report.
Stock pipe diameters with custom perforation: typically 5–10 working days. Larger volumes or non-stock parent pipe: 2–4 weeks. Confirmed lead times come with each formal quotation.
Filter sock and geotextile wrap material can be supplied separately or pre-installed on the pipe to project specification. Specify the filter grade (e.g. 150 g/m² geotextile) in your enquiry.
