Putting wood inside a vacuum tank will make it absorbs more chemicals that will protect it against frost, fungi, woodworm and moisture retention.

Once treated the timber is ready to be used for decking, structural frames, fencing, posts and trellis projects. Treated timber will not rot or grow fungi which makes it longer lasting when in an outside environment.

  • Protects against moisture retention
