I am water proofing my basement……installing drain pipe around permiter of basement inside.
I had a company bid the job… before I did it myself they were going to use a white laminate sheeting 4×8 to install on the walls but it had channels on the back so it did not go all the way against the wall so the water could channel to the drain pipes. Does anyone know where you can buy these sheets?

To be honest I've never heard of this product but I am posting so that your thread gets bumped up and hopefully somebody else can help.

It sounds like the water is entering through the walls? Yikes - that's some serious hydraulic pressure.
I'd recommend solving the problem rather than treating the symptoms. Figure out why the water is comming in. 3 things possible - Poor grading (get water away from building. That starts with gutters and downspouts directed away from the building sufficiently). Non draining soil next to foundation (I just saw a job where the owners had to excavate the foundation because the builder backfilled with silty/clay subsoil and water just got sucked toward the house). Underground spring - find it, use a crushed stone collection system and drain pipes to direct the water away.
Any solution you use to deal with the water inside will not be sufficient and reliable enough to manage the water so you can finish the inside of the basement (presuming this is your goal?).
If you want to use a grooved product - check with a commercial EIFS supplier for a draining EIFS foam. The rigid foam is backgrooved to allow the EIFS to drain when water gets behind it - it works on basements also. The foam insulates the wall while permitting drainage.
There are many other details to accomplish the wall system but without more details of your construction it's hard to advise.

The sheets you mention may be proprietary to their franchised system if that is what it is. I know there are a couple out there.
But what you are doing is definitely NOT called waterproofing. You are merely diverting the water in hopes that you will not see quite as much of it. Two thirds of your problems will still remain and keep getting worse.
