A fundamental need for life is the need for water. However, as effective drainage is crucial for agriculture as well as the development of sports facilities, roads, and buildings, the unchecked flow of water can frequently result in issues.
Corrugated pipes are known for their "sandwich" design. The corrugated pipes' outer wall gives them a greater degree of rigidity and stability, while the inner wall's smoothness allows for the fastest possible water movement. internal and external walls have homogeneous connections. The Double wall corrugated drainage-sewerage pipes with partial perforation are the ideal perforated and collecting pipe combination. The Double-wall corrugated drainage - sewerage pipes with perforated or slotted openings are an ideal solution for drainage and collection applications.

Typical Trench
After several tests, Polethylene pipes have shown to have the least exposure to corrosion from the movement of particles during the flow.
Trench Cross-Section Of Corrugated Pipe
- Final Backfill: Decompressed area of soil (cross-sections are excluded)
- Initial Backfill: All solid materials are removed, decompressed area of the soil.
- Bedding area: Decompressed area of sand.
- H₀: Distance between the ground and the top of the pipe (has to be minimum 50 cm).
- b: Width of the trench (mm)
- Y: Height of the bedding layer (mm)
- DN:Pipe outside diameter (mm)
- Burial depth: Min. 1 meter – Max. burial depth: 5 meters.
A 20% reduction shall be applied to the maximum allowable burial depth due to the presence of slots or perforations.
