Basement Kitchen Floor w. Platon

Although the p.o. said there were no problems with water in the basement (of course), we found puddles in the basement kitchen after heavy summer rains. So, we knew that we needed to solve that problem before we rented it out. When we tore up the old vinyl floor, we discovered an old floor drain that hadn't been sealed up. Could this be the cause of our water? Since most of the pools happened right around the drain, we think it's a good possibility. We closed that up with cement, and then we chose to subfloor with Platon subflooring.
* NOTE: It's WAY cheaper than "Dri-core"! *

With the newly covered drain, a subfloor, and a good dehumidifier, we hope that any water issues are taken care of!

Man, was it ever fun to level a 100-year old basement floor slab! (sigh).

Hi,

We're planning to refinish my basement too in western NY here in the states. We started looking at this Platon material and saw you are planning to put OSB over it then laminate flooring. Can you tell us why not just flooring over the Platon?

Good luck and have fun with your project.

Hi Jack!
Thanks for the comment. Sean probably has a more technical explanation about why we are using the OSB, but here's my layman's view- The platon doesn't provide a really firm, flat surface to lay laminate on... It's strong, but keep in mind that it is also plastic-like and comes in rolls, so it's bendable. It seems like the laminate would likely move around more and make more noise without the OSB on top of the platon to weigh it down. So, it's to have a better surface for the laminate. We are using very thin OSB though- I think only a 1/2 inch. Hope that helps! Good luck!

Thank you for the quick reply. We will follow your led on this.

I am curious as to your cementing the old basement floor drain. Aren't you worried that water can back up into your house else-place (e.g a sink, toilet, or tub)? From my understanding, the floor drain is to prevent water from backing up into the house.

Hi Terrin-
The floor drain that we covered with cement was actually hidden under the linoleum we tore up- we had no idea it was there and we're pretty sure it no longer serves any purpose. We have another newer floor drain located in the center of the basement that serves the function you are talking about. Hope that helps!!

Hi, I was wondering how you fastened the osb over the platon or if you just laid it down and hoped it wouldn't move?
Also it looks like you did it a couple years ago. Are you still happy with the results and now with hind site would you have done it differently?
I am wanting to do my basement and would like to do it right the first time, thanks for any advice.

Hi Vince,
We didn't fasten the OSB down with anything. We did get tongue and grove OSB and fit the sheets together when we laid them down, but they were heavy enough that we didn't need to fasten them. Depending on how level your floor is, I would recommend the tongue and groove (our floor wasn't level at all, and this helped put it all together.)
We are super happy with the way it all turned out. We actually had a pipe break in the laundry room, and the water all flowed beautifully under the platon to the floor drain on the other side of the room- if we hadn't done the platon, our new floor would have been totally ruined. So, if there's any advice we can give, just make sure you don't block any chanels for water flow to your floor drain!

I am going to install the Planton and an OSB board over it. I have been trying to get my head around the laundry drain issue. How do I ensure that if there is a pipe burst in the laundry area, the water will get below the planton and into the drain?

I think you might have the wrong idea about platon. Water won't go through it to get to a drain if the water is on TOP of the finished floor- in fact, you tape up the platon and it makes a waterproof seal so that water can't get up from UNDER the floor. Platon is to ensure that water that might come up from the floor can travel under the floor to a floor drain, without causing moisture problems or mold problems in the basement. If you have a laundry room that sometimes overflows, I wouldn't put a finished floor in there and cover up the drain. You need to make sure the water can get to the drain. Now, if it floods in an unfinished area, it can get UNDER the platon in an adjacent finished area and find the drain. Hope that helps.
