Moisture Meter - Test Floor Screed Moisture Before Tiling

[Ian]

I'm thinking of investing in one for peace of mind on new slabs. Can anyone recommend a particular model or a link or two. Thanks Bri

Concrete, as in the substrate, not for making a patio!!!! Just read what I wrote and it sounds like I'm on about paving slabs!!!!

I just ask as you need a different type for Gypsum based ones..

No just a standard, concrete jobbie. I'll cross the gypsum bridge when I get there, I've not had much to do with them really.

On cement screeds Bri, i just do a sweat test.. easier IMO..

Thats my normal route, just wondered if there was a good one, thats accurate. Don't want to spend a fortune, but on the other hand don't want one to get one if its not really necessary.

I think they are ok for walls if it's a cheaper one but for a 75mm+ screed then you will have to move up to a really pricey one.. could be 400 quid or so..


Google is ya friend.

I did have a look on ebay earlier and the prices range from a few quid to a few hundred. Its not something I know a great deal about, but if a good one is that much I'll stick to a good old bit of polythene!

One I've had demonstrated ( and considering) is the Protimeter Surveymaster. As well as having the contact measurement and the probes you can measure the moisture up to 20mm below the surface without drilling. With this you make an instant assessment on the moisture within a slab the theory being if it's dry enough 20mm down all is well. It is pricey tho certainly over £300.
