Application

Heavy building

  • Formwork systems;
  • Precasting.

Description

Riga Poliform is a speciality formwork panel with superb mechanical properties and is designed to last longer with as many as 300 uses depending on specific end-use and site practice.


Features and benefits:

  • Tough and impact resistant surface for smooth concrete finish.
  • No rippling.
  • As many as 300 reuses when correctly installed.
  • Recycled wood fibres utilised in the wood-plastic overlay.
  • Water resistant surface and weather resistant gluing.
  • Surface is resistant to commonly used concrete release agents, diluted acids and alkalis, easy to clean with water or steam for repeated uses.
  • Special solutions are available for applications requiring a higher surface elasticity such as nailing.
  • Easy to machine and fix on site.
  • Variety of standard sizes, cut-to-size and jointed panels available.
  • Sustainable product with long life-span.


Further processing

Riga Poliform can be further processed according to customer's specification with cut-to-size, CNC, drilling, milling, jointing, edge machining, and assembling in sets.


Surface properties

The wood-plastic composite coating offers a highly durable, hard and dense surface, increasing panel resistance against mechanical damage and wearing. It resists concrete release agents, cement alkalis and other corrosive chemicals. The panels can be used within a temperature range from −40 °C up to +80 °C. Cold temperatures can reduce WPC flexibility making it less suitable for nailing. After use, panels release well and maintain their performance for a long time. Riga Wood experts will advise the most appropriate overlay depending on the end use.
