Some Products I Test Are Not Fit For Purpose

Sid Bourne raves about the ‘most advanced’ system

AS I travel around the country inspecting flooring problems, it is very clear that the number one reason for failure is moisture and related problems.

I see floorlayers and retailers who think they are testing correctly by using hand held moisture meters which send a signal through the concrete, usually to a depth of 30mm. These meters are excellent in combination with a relative humidity tester. However they are only indicators of moisture, not to be fully relied upon as the gospel.
I also independently test tools and equipment and write truthful reports on my findings, which include ease of use, cost, and effectiveness and so on.

Whoever asks me to test knows full well that if I am not 100% happy with the product, I will put this in writing. Then it is up to that company to decide if they want to publish it. It is no secret that not all the products I test are fit for purpose.

Sorry to be blunt, but it is true and often these products don’t generally go public. However those I find do what they say on the can will get published. For example the latest test results on the Tramex Hygro-I probe- relative humidity testing system.

I have been testing this product on-site for the last couple of months and my findings are that it is by far the most advanced system on the market without doubt. Why? It’s simple to use and it does exactly what it says on the
can. For example, the plastic sleeves supplied with the system are longer than you would expect normally in other kits.

The reason for this is that this system comes with a sliding steel rule to measure the depth required and a pipe cutter similar to what a plumber uses to cut the exact length required.

The special bit for me was the system also comes complete with Hygro-1 probe, including a special lock tube to safely insert the probe into the sleeve. You then simply turn it and the probe is in place. This is followed by a clip- on top to protect where probe inserted. Once the time for taking readings has elapsed you simply take off cap and insert your hygrometer probe into unit and get readings.

The clever bit which makes the system very economical is that you can take out the inserted probe and re-use again as it can still be checked for calibration. In fact, the kit comes with a calibration Hygro-1 calibration check so no more costly having to re-buy new probes.

I would recommend going onto the Tramex website and see this system in action. It is much easier to understand and shows how easy and economical it is. This is a ‘must buy present’ for any installer.
It is vitally important to always conduct relative humidity tests on concrete floors. This is in the BS standard and will give you full peace of mind.

A typical scenario I came across recently was a concrete subfloor which had a breach in the DPM. The floor had been down for four years, and I asked the installer what test he carried out.

He said he had not done any because as the floor was only four years old it could not have any moisture. But on testing this floor with the Tramex Hygro-1 system I discovered that a breach of the DPM had occurred or there was no ground DPM.

The job had gone legal at this stage, so based on my findings it was required for the subfloor to be taken up. It was found that the builder had not used a DPM quality sheeting. So as luck goes I was able to get the installer off in this case, but it could so easily have gone the other way if the court had decided the installer should have tested. However it never came to that.

Take my word for it the Tramex Hygro-1 System is money ver y well spent.

I have also used this product in front of attendees on the British Wood Flooring Association courses and they are all blown away with the system.
