    Use Class 4 (UC4)

    Use Class 4 is for end uses where wood is in contact with or very close to the ground. When it comes to UC4, 15 years is taken as the default service life unless 30 years is specified, however this is not a garuantee. The 15 years desired service life can vary depending on the envrionment the treated wood is left in and can be shorter or longer than the desired life stated here.

    For wood in permanent ground or fresh water contact, or providing exterior structural support, Use Class 4 levels of protection MUST be achieved. Anything less and service life, structural safety and customer satisfaction will be compromised.

    If using a cement based mix to fix posts in the ground, ensure that water can drain away from the foot of the post.

    When cross cutting, notching or boring treated timber products during installation, ALWAYS apply an end grain preservative treatment to freshly exposed areas to maintain the integrity of the protection. NEVER put cut ends in the ground, even if end grain is coated.
