140 x 45mm H4 TGV Interlocking Retaining Wall - 4.8m

Designed for ground contact applications, this interlocking timber is ideal for retaining walls.
Made from legally harvested, New Zealand-grown Radiata Pine and treated to CCA H4 standard for enhanced durability and long life.

Note for garden use: If using in vegetable gardens, it's recommended to use a plastic liner to avoid direct soil contact. Alternatively, untreated Redwood or Macrocarpa sleepers are a preferred option and can be used without a liner.
