Subdrain/Weeping Tile

Single wall corrugated HDPE pipe is ideal for drainage projects where flexibility, lightweight and low cost are important.

Solid, Perforated and Perf Socked in stock. Plus every fitting you need to get the job done.

Single wall corrugated pipe has kept farms, golf courses, parks and playing fields dry for decades by channeling away excess underground moisture.

Homeowners find that the single wall HDPE corrugated pipe is an economical, easy–to–install solution to common residential stormwater drainage problems. These may include downspouts runoff, foundation and window well drains, driveway culverts and wet spots on the lawn. Single wall HDPE pipe is also used for highway edge drains, culverts and other construction applications where economy and durability are a priority.

Subsurface drainage through Subdrain/ Weeping Tile installation and management works by removing excess water from fields. Improved field drainage creates significant benefits for your soil health, environmental impact, and increased crop yield for larger profits year after year.

1. Reduces Excess Water
Subsurface drainage redirects water away from areas with a high water table. This is critical for areas with frequent flooding and soil saturation that can negatively impact crop health.

2. Increases Drought Tolerance
In areas where drought is a challenge, subdrain systems can be used to improve water retention in the soil, or divert excess rainwater to holding ponds for future use.

3. Minimizes Erosion
Soil erosion and degradation can be caused by excess rainfall, resulting in loss of soil volume. This can be magnified by traditional plowing methods. Improved drainage can reduce the impact of heavy rainfalls, helping to preserve soil nutrients and the surrounding areas of your property that can be affected by erosion.

4. Lowers Environmental Impact
Agricultural runoff can be high in dissolved minerals and organic compounds, which can cause issues for neighbouring water supply. A drainage system will ensure that this runoff is redirected to avoid local rivers and ponds, protecting the local ecosystem.

1. Removes Excess Water
Effective subsurface drainage removes excess soil water in the root zone, allowing for improved soil aeration. Prolonged exposure to saturated conditions and poor soil aeration can stress the crop, reducing yield.

2. Increased Workability
Drainage can improve field trafficability, allowing more reliable field access while reducing compaction. Drier soils are less susceptible to compaction than wetter soils.

3. Deeper Roots
Drainage enables crops to establish deeper root systems in fields, allowing greater access to nutrients and soil water.

4. Improved Consistency
Drainage can reduce the year-to-year variability in yields from poorly drained fields. Drainage can increase nitrification (the conversion of ammonia to nitrate) in most soils, providing more nitrate for plant uptake.

Farmers have told us that they expect a 10 – 20% increase in crop yield after investing in proper drainage.
