Wolman: Vacuum Pressure Impregnation Products

Vacuum pressure treatment

Provide long-lasting protection for your wood in constant contact with earth

Be it palisades, pergolas, carports or playground equipment – wood needs protection.

Particularly when used outdoors in constant contact with earth, our indigenous, relatively low durability wood types are at risk from fungi, insects and the elements. Vacuum pressure impregnation can provide lasting protection for these types of timbers...

What are Wolmanit® CX and Wolsit® KD?

Modern wood treatment 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.

The Wolman range can justifiably claim to fulfil both these requirements. Wolmanit® CX - or Wolsit® KD - products. The right solution for every application. The innovative Wolman preservatives provide the basis for durable wood protection. Water-repellent additives and paints turn standard wood products into premium products of the highest quality.
