Low pressure Impregnation

For over 20 years Timber Preservation Technologies have designed built, tested and commissioned many innovative timber treatment plants that utilise cutting edge engineering technologies.

Our experience allows us to supply you with the technology to utilise the latest generation of water-based preservatives for wood preservation. 

 

When to use Low Pressure treatment?

You should only use low pressure treatment when the timber is going to be used indoors. This relates back to the Use Class system, and you can see the classes below which are relevant to low pressure treatment: –

Use Class 1 – Suitable for internal timbers that will remain dry. E.g. upper floor joists and truss rafters

Use Class 2 – Suitable for internal timbers that are exposed to a slight risk of wetting or damp. E.g. tile battens and CLS framing

Low pressure treatment generally uses only atmospheric pressure and a water based treatment which helps to protect it against fungi and wood destroying insects.

From any preservative supplier as required

  1. Timber charge is sealed in the treatment vessel
  2. Vacuum applied causing timber cells to be evacuated of air
  3. Vessel is flooded while the vacuum is maintained
  4. Preservative is forced into the timber under atmospheric pressure
  5. Vessel is emptied
  6. Vacuum applied to the timber again to evacuate left over preservative
  7. Left over preservative is recovered to the storage tank
  8. Timber charge removed from treatment vessel

All equipment can be supplied either Ex-Works or Fully Installed, whichever works best for you. We have access to a wide network of transport, crane and plant hire providers to allow us to achieve even the most complicated of installations.

We also have our own lifting equipment including the following: –

  • Reachstacker capable of lifting 45T
  • Wheeled Hydraulic Lifting Frame capable of lifting 80T
  • 2no. 10T Fork Lift Trucks

Any of these can be transported to site if the job requires it.

Case Studies – Coming Soon

The importance of effective and environmentally sustainable wood preservation methods cannot be overstated. Our many years in the industry (under the Tweddle Engineering brand) led to the development of a range of wood preservation techniques, and some brand new, award winning timber treatment technologies! The importance of timber treatment is unlikely to wane so learn how our innovative wood treatment technology solutions benefited these companies!
