Combi Posts
A Durable Choice

Combi-posts for sheet-piling consist of an untreated pinewood post with a plastic top-piece.

The pinewood post is situated underwater and only the plastic top-piece protrudes above the waterline. This prevents rotting caused by the interaction of air and water. The top-piece can be worked in the same way as wood; i.e. it can be sawed, drilled, bolted, etc. Because they are maintenance free and have an extremely long lifespan, purchasing Combiposts ultimately leads to substantial cost reductions.

Reasons to use Combi Posts:

  • Maintenance free
  • Durable (lifespan of more than 40 years!)
  • Does not rot or splinter
  • No leaching

Recycled plastics is the environmentally friendly solution

Increasing concerns about the environment, especially the controversial use of tropical hardwood and chemical treatments, has sparked a search for alternatives for waterside construction projects, we provide all the materials that modern marine construction engineers need to start work. including planks, sheet-piling, jetties and bridges. All these products are made completely from recycled plastic.
