Series Kaczmarek - DREN SN4

Kaczmarek - DREN SN4

Welcome to the Kaczmarek - DREN SN4 drainage system. This series is built for reliable water management in residential, commercial, and landscaping projects. The pipes are made from high-quality PVC and feature a corrugated design for strength. They come in bright yellow for easy site visibility and meet SN4 ring stiffness standards, meaning they handle soil pressure and traffic loads without deforming.

Pipe Types and Perforation Options

You can choose between two main pipe types to match your project needs. The TP type is fully perforated around the entire 360-degree circumference, allowing water to enter from all sides. This is ideal for areas with high groundwater or heavy rainfall. The UP type has no perforations and is used for collecting and transporting water without leakage, such as in sump pits or transition zones. Both types are available in rolls of 25 or 50 meters, with diameters ranging from 50 mm to 160 mm.

Filter Options and Geotextile

To keep your drainage system running smoothly, the TP pipes come with built-in filters. You can select a polypropylene (PP) filter for standard soil conditions or a coconut fiber filter for better organic filtration and longer life in clay or sandy soils. For extra protection, we also offer a separate PP geotextile fabric (90 g/m2). Wrapping the pipes in this fabric prevents soil and roots from clogging the perforations, ensuring long-term water flow.

Fittings and Connections

Completing your drainage layout is easy with the full range of black PVC fittings. The series includes couplings, elbows, tees, reducers, plugs, and transition pieces that connect drainage pipes to standard sewer lines. All fittings are designed for quick, secure connections and match the SN4 stiffness of the pipes. Whether you need a straight extension, a 90-degree turn, or a branch line, the Kaczmarek fitting range covers every standard diameter from 50 mm to 160 mm.

Installation Benefits and Durability

Installers love this system for its straightforward handling and reliable performance. The corrugated structure makes the pipes flexible yet strong, so they bend around obstacles without cracking. The yellow color helps you spot them quickly during trenching, and the lightweight design reduces physical strain. With SN4 rating, these pipes resist crushing under backfill and light vehicle traffic. Combined with the right filter and fittings, the Kaczmarek - DREN SN4 series delivers a clog-resistant, long-lasting drainage solution for any job site.
