Corrugated PVC Drainage Pipe TTPLAST RKLSP 25/20-50 FI20/25 with Pilot, 50 m

TTPLAST RKLSP 25/20-50 FI20/25 with Pilot, 50 m is a corrugated PVC drainage pipe designed for subsurface drainage and controlled water diversion. Supplied as a 50-meter roll, the pipe combines a flexible corrugated profile with sufficient structural strength for installation in agricultural fields, landscaped areas and construction trenches. The integrated pilot helps guide the pipe during placement, improving alignment and ease of unrolling in narrow trenches.

Advantages

The corrugated PVC construction delivers a balance of flexibility and compressive strength, allowing the pipe to adapt to uneven bedding while resisting soil loads. Being lightweight and supplied on a 50 m roll reduces transport and handling time on site. The integrated pilot assists in accurate laying and keeps the pipe straight during trench installation, decreasing the need for manual adjustment. The smooth inner surface supports efficient water flow and reduces sediment build-up.

Suitable for

• Subsurface field drainage in agricultural plots
• Landscape drainage for gardens, parks and sports fields
• Construction site drainage and foundation perimeter drainage
• Drainage of roadside verges and public utility corridors

Key specifications

• Material: corrugated polyvinyl chloride (PVC)
• Nominal diameters: compatible with 20 mm and 25 mm fittings (FI20/25)
• Supply length: 50 meters per roll
• Profile: exterior corrugation for flexibility and stability
• Inner surface: relatively smooth for improved flow
• Integrated guiding pilot for easier alignment during laying

How to use

Excavate a trench with stable bedding and the appropriate slope for gravity drainage. Unroll the TTPLAST corrugated PVC pipe along the trench, using the integrated pilot to maintain alignment and a straight run. Connect fittings compatible with FI20/25 nominal sizes where required, ensuring joints are secure and watertight according to local practice. Backfill with suitable granular material around the pipe to provide even support and avoid point loads; compact bedding in layers to maintain alignment and prevent movement.

Usage recommendations

For long-term performance, place a geotextile filter or appropriate aggregate around the pipe in soils with fine particles to reduce the risk of clogging. Avoid sharp bends beyond the pipe's recommended curvature; where direction changes are needed, use appropriate fittings or short transition sections. Store rolls on a flat surface away from direct sunlight before installation and protect cut ends during placement to prevent debris entry.
