Trench drain in shower using Kurdi

[fredonparkln]

Have been searching for a trench drain that is compatible with Kurdi waterproofing. So far have found 2 trench drains but not sure that any will work with Kurdi---Stormtech available in US from infinitydrain.com; Quick Drain at quickdrainusa.com. Any one have any experience with these or others using Kurdi??

The best place to pose this question is at johnbridge.com, which does for tiling what this place does for plumbing.

BTW, the name of the product is Kerdi.

Fair warning: John Bridge site people brook no dissent and will corral you into their mindset, which must promote their sponsor's products, and obviously also as per the sponsor's prescribed methods which allow no other drain to be discussed. Mixing any other product with theirs is the biggest no-no, and they will find ways to sprinkle doubt flakes all over your discussion thread if you keep posting. Or fear flakes, or uncertainty flakes. I don't know whether they've changed over the years; perhaps they are more independent now, in terms of their beholdedness to their main sponsor, but I dropped them completely once I saw who they really were underneath it all, and how they operated. The pro's in their pro forum are forbidden from helping newbies think independently too, so even if you get a thread going over in the pro forum you won't get any really truthful responses. Searching deep, you'll see that professionals do mix and match products to suit their needs. It does make sense that they would leave you hanging, not knowing what they would do; what I object to is all the "friendly" front to their shilling and half-truthing. I caught a few doozies and I was told to henceforth only post on my own threads concerning my own projects and also to do certain other things and not to do certain other things (and also never to mention these restrictions or else suffer forever)....

hmmm.

There's a discussion at www.johnbridge.com (http://www.johnbridge.com) now about how to do a trench drain with Kerdi. They promote properly constructed showers per the TCNA. Lots of people make them with mudbeds and liners. If you've seen how a shower performs, you'd understand that a good surface applied membrane has many advantages. Schluter and Noble both make a good product. Both are discussed. What they don't abide by is a shower that is not build per accepted standards. You might call Schluter and see what they have in thoughts about a trench drain. They have some products that aren't in their catalog. For example, they can get you a working tub drain that will work with Kerdi. They may have other things as well.

There are a lot of technical issues about any drain...by their nature, they must make a good seal with the liner. Kerdi is designed to make a good seal if you can overlap it properly onto a surface that will allow the thinset to bond. Clamping it is possible, but not the preferred method. By far the easiest way to do it is with their traditional drain. If you really need a trench drain, there are ways to do it. Kerdi fix or another urethane adhesive might work, but is a thin layer of defense...a wide thinsetted joint is better. Kerdi repels water, so the wider the joint, the bigger the margin of safety. relying on a narrow band of sealant doesn't give you much tolerance for success.

That site has multiple sponsers, and many advocates. But the responses you'll get are pretty good...give them a try.

Liquid trowel-on, paint-on membranes will be good for a trench drain. They follow the shape you build. Check into "Redgard" and others like Redgard.

This is an old thread but many more options are available today.

Schulter does not have a channel drain in production to my knowledge and Schulter will not warranty any third party drain fully if you mix and match your materials. This information was given to me personally by Dale Kempster of Schulter (highest technical representative at Schulter).

I have personally installed two channel drains using Kerdi - one from ACO and one from Quick Drain USA. The key ingredient is Kerdi Fix but the installation will not be backed by Schulter...

Consider a linear drain from My Shower Grate Shop, ACO, Nobel Company, Heel Guard or Quick Drain USA - all these companies make excellent products and are a pleasure to work with - all can offer you fantastic warranties and customer support.

If your still looking for answers - post your questions on a new thread...

I went out to see my first Schluter Channel Drain installation last week and found a European Drain. It was waterproofed with Kerdi from Schluter but it was not a Schluter line drain.

I am almost 100 percent certain the clients I visited where sold a channel drain by "Easy Drain" but they where under the impression it was the new Schluter Line Drain or Kerdi Line Drain.

Here is a few pictures of the drain I viewed;

You can see that the Kerdi Line drain has a distinct Stainless Trim that incases the one of three grill options shown.

We are authorized distributors for one of the Trench Drains you mentioned. However, because of the high price we were losing some customers and began searching for another product at a more affordable price point so we could offer another solution to our more cost conscience customers! In January we installed 3 Linear Trench Drains purchased at www.whatadrain.com, and than 2 more in February. We really like the price point, find that they are very easy to install and offer considerable flexibilities. For those of us using the Schluter Kerdi Membrane, you can now order this product with a 5" glue flange factory installed. We have been very pleased with the results AND more importantly so have our customers!

I dont see how this drains off the sides of the drain or between the wall and the drain. It appears to be set in a large tile which cant be sloped in all direction towards the drain. Right?

How do you get the water to drain from the left and right side of a linear if its not running the full length of the wall?

This is a good observation and one question I have been asking for answers. I think the drain would be better installed edge to edge to avoid this all together or to have a boarder or accent tile installed as a border. I do not like the idea of having any lippage at the low point of the shower and it's much better to have the tile a hair higher than the drain grill.

The "What A Drain" product is a new product and to my knowledge does not have a UPC classification as a shower drain. The installation instructions online recommend the use of Kerdi but there is a very small attachment location. I also do not like the fact that the drain can not be snaked after following the tile installation.

"What a Drain" showcase a drain cleaning tool for cleaning but I think this drain's design not lend itself to proper cleaning by grill removal.

I will try and located a UPC classification for this drain and find more information on the grill option they have.
