Why just "Treated" timber isn't good enough
|
Ask any timber merchant the question "...is it treated?" for any products you are purchasing designed to be in ground contact, and the answer will normally be "Yes". That is usually the end of the conversation, but it shouldnt be - and here's why - Take a look at the two pine posts below. From the outside, both look the same (treated), but cut in half you can see the true picture of how long they are likely to last:
Figures (A) are green on the outside but completely untreated on the inside! And will last no more than a few years. Figures (B) have treatment right through the sapwood, the most vulnerable areas, and well into the heartwood. Posts treated in this way should last for many years, at least 15-20 years in fact!
'Guarantees' are not Guaranteed! What is the point of having a guarantee on an inferior product? They generally only relate to the replacement cost of the original post you bought. Assuming you can prove you bought the defective posts from that supplier, you then have the far greater cost of re-installation that you will have to pick up yourself. And what will you be replacing it with...another inferior post! |
How we do things differently
- No compromise on quality of treatment
We set no limits on kilning times or amount of treatment chemical used, and specifically use the treatment chemical we believe to be THE BEST, not the cheapest!
All our tagged posts are treated to (Hazard) Class 4. (if your posts are Class 3 or lower, they will NOT be suitable)
- We control every part of the treament process
From selecting the correct species and quality of timber used, the Kiln Drying process, and vacuum pressure treatment impregnation. We have extensive on site facilities to achieve this unlike the majority of our competitors.
- We work closely with our chemical supplier
This allows us to run constant independant checks on our treatment quality and penetration. As well as on site, samples are sent to be analysed under laboratory conditions.
- Each post individually tagged & recorded
Our posts are each clearly end tagged with our company name and a unique identification code for any future reference. Unlike some other tags and labels used in the industry, ours are designed NOT to deteriorate over time.

Choosing the right product
This checklist provides a comprehensive guide in selecting timbers you are using for in ground contact. If the answer to any of the questions is negative then they should be avoided:
 |
 |
|
|
What species is the Timber? |
Redwoods - especially pines are regarded as only species suitable for in ground contact |
Spruce / Firs or non Redwoods |
|
Has it been dried to a moisture content of below 28% before treatment? |
Kiln drying the posts correctly reduces moisture content dramatically |
Less treatment
absorbed when the posts are wet |
|
Has all the machining been done prior to treatment? |
Machining exposes
untreated areas |
'Brush on' treatments are no match for vacuum impregnation |
|
Is the treatment chemical used mixed to the correct concentration? |
Correct mix should always be used |
Weaker chemical is less effective |
|
Has the Timber been treated to (Hazard) Class 4? |
British Standard ensures post longevity |
If answer is Hazard class 3 or below, timber is NOT suitable |
