Vacuum pressure treatment

Modern wood preservation places high demands on research and technology. Today, preservatives must be effective and at the same time comply with the legal requirements for environmental, health and occupational safety. Wolman products offer you this security in all applications, whether with decking or structures that are subject to heavy loads such as wooden roller coasters. 

Wolmanit® CX or Wolsit® KD products. The right solution for every application.


Sinesto® and Wolsin® products provide wood with reliable protection against sapstain and other wood-staining fungi, such as mould.
