Certification in the wood preservation sector
Outdoor development projects that fit out places (playgrounds, street furniture, etc.), make them more attractive and delimit or facilitate access to public or private spaces.
The products involved are round
timber, unplaned or planed sawn
timber for use in use class 3.2 to 4.
Given the duration of service
and contact with the public, it is
recommended to use CTB-B+
treated timber for use class 4.
CTB-B+ treated timber ensures
the durability of these strustures.
It should however :
• avoid water traps
• prohibit any machining after
treatment. However, for cuts and
holes above ground, the exposed
surfaces should be treated with a
suitable product to help rebuild
the initial level of protection.
CTB-B+ treated timber does
require the application of any
additional products to ensure
It should be maintained by cleaning
using a brush and/or water jet (high pressure prohibited).
