Application
To ensure your Drainage System performs at its peak, follow these expert tips:
- Retaining Walls: Backfill a minimum of 300mm width of Pea Metal behind your wall. For best results, separate the metal from the soil using our Non-Woven Weedmat to prevent clogging over time.
- French Drains: Surround your perforated drainage coil with a generous layer of 22mm Pea Metal. This creates a “sump” effect, drawing water into the pipe efficiently.
- Soak Holes: Fill soak pits with clean 22mm metal to maximise void space, allowing for greater water storage capacity during heavy Bay of Plenty rain events.
- Garden Health: In areas with heavy clay soil, mixing pea metal into the subsoil or using it as a base layer in garden beds significantly improves aeration and prevents root rot.
