Lamitech decoupler

[Ian]

This is porcelanosas own decoupler, does anyone have any experience of it as there doesn't seem to be a great deal of reviews available on it. I've heard one story of a failure but can't find anything to back this up so just wanted to know if anyone had any views on it.

 

[DHTiling]

Never heard of it,, is this on a roll or sheets like plastic ply..?

On a roll Dave, similar build to Dural, just blue instead of yellow.

 

[DHTiling]

Ah.. so it is Blanke's one..

Only Dural so far have the new version..

 

[Ian]

This is the only info I've got on it, I'd prefer a review as I'm very wary of a new product.

lamitech

Lamitech is a semi-rigid polyethylene sheet measuring 3 mm. in thickness, made up of a highly resistant alveolate membrane, covered on the bottom part by a textile sheet. This structure forms a network of hollow channels, which enables the installation surface to be separated from substrates that are uncured or exposed to great stresses.

Lamitech is specifically designed to allow the installation of ceramic and stone tile over any even and load-bearing substrate. The characteristics of this membrane are:

- Uncoupling: Lamitech provides uncoupling through its open bubble structure, which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface.
- Waterproofing: Lamitech provides reliable waterproofing in interior and exterior applications. Its polyethylene composition protects the substrate from moisture penetration, which is particularly important when moisture sensitive substrates are used.
- Vapour management: the main feature of Lamitech is the existence of free space created by the configured channels on the underside of the matting. The free space provides a route for excess moisture and vapour to escape from the substrate that could otherwise cause damage to the tile layer above.
- Support/Load Distribution: Columns like mortar structures are formed in the cutback cavities of the matting. Loads are transferred from the tile covering through these column-like mortar structures to the substrate and distributed while preserving the integrity of the tiled surface.

Most suitable substrates for Lamitech

- Concrete. Lamitech absorbs inherent stresses between the concrete and tile covering. The tiles can be installed a soon as the concrete is hard enough to be walked upon.
- Mortar screeds. Lamitech improves the vapour migration in the cement mortar and reduces the stresses due to cracks or shape changes in the floating screeds. The tiles can be installed a soon as the screed is hard enough to be walked upon.
- Wooden subfloors. The loading and changes in moisture content produce deformations in these materials. Lamitech allow installing tiles over single layer wooden subfloors. Requirements of the substrate:
o Capable of carrying the expected load without excessive deflection.
o Screw fixed to supporting joists at a maximum of 300 mm centres
o In good condition, dry, securely screw fixed and the fixings do not protrude.
o The recommended adhesive is super one n
- Waterproofing. Lamitech can be used for waterproofing in applications not exposed to constant water pressure. The joints must be sealed with the butech lami-band fixed with super one n.
- Balconies / terraces. The extensive and frequent temperature changes can be neutralized by using this uncoupling membrane. Lamitech provides an effective waterproofing.
- Anhydrite screeds. Lamitech protects the anhydrite screed against moisture penetration from the surface. The tile covering can be installed as soon as the residual moisture is below 2.0%. The substrate must be primed beforehand, with butech Universal Bonding Agent.

This is supposed to be a brand new version of this product, looks more like underlay for wood floors! It's got a felt back an a rubber top, what do you folks think?

Never heard of it, I buy DURAL .

 

[kilty55]

looks odd brian,lamitech....name suggests its for under laminate also

have you used it yet?
wouldnt it be safer opting for a more known brand mate?

 

[Yorkshire Tiling Services]

Plenty makes out there, Schluter was original, however they will always say their produt best... as time has gone on, there are many competitors out there, most should do the same job.,make sure you follow installation instructions to the letter so as not to invalidate any guarantees. Many faliures result from incorrtect installation and fixing.

Looks a bit like the Homelux Floor that I use quite a lot of, only that look a bit thicker.....

Only reason I'm fitting it is the client has supplied. Normally use dural. I don't see how it can work as a decoupler, I'm sat in the van waiting for a call about installation instructions, could be a while as this is Porcelanosa! Customer service from hell!

If in any doubt............... walk away !! Otherwise it will come bak to bite you.

There are no cups on the topside of this, and as far as I'm aware from reading up on decoupling systems, this is an essential part of the decoupling process. Is the homelux product like this.

Almost the same Bri... Homelux Floor has a waterproof membrane on top and a thick black flock on the back. I use it in all my wetrooms if they have a heatmat.

I've never heard of this one and they will not give me a definitive answer on how to install it so I've asked the client to let me use ditra, if they can't be bothered to send me a PDF they obviously don't know alot about their own product.

[Stewart]

Ditch it then and use the Ditra. You cant install without the full installatin info, so you can assess it's suitability

That's better!

Good choice Bri, though your fixing method looks a bit sus....lol

 

[DHTiling]

I had to look twice then... then i realised it wasn't struck down :lol:

 

[Ian]

Very funny Gents!!!!!!!

 

[White Room]

I did show concerns Bri with the air pockets, nearly went into stalking mode:lol:
