Terence McCann Posted July 8, 2009 Report Share Posted July 8, 2009 Often, when they waterproof a basement, they apply a material to the basement walls. It is white and the exterior is comparable to the surface of an orange. Correct name of the material is??? Quote Link to comment Share on other sites More sharing options...
Mark P Posted July 8, 2009 Report Share Posted July 8, 2009 I often refer to it by the trade name "DRYLOK", but should probably just say "Masonry Waterproofer" Quote Link to comment Share on other sites More sharing options...
Les Posted July 8, 2009 Report Share Posted July 8, 2009 Terry, Now that I am much older and wiser, I would caution you about a couple of things in your question. How do they apply the material "to" the wall? I like to think it is "on" the wall. Just because they apply it on the wall does not make it a waterproof material. If it is on the interior of the basement wall I would write "Someone has smeared crap on the wall to stop the water from coming in through the wall." Or, the crap they smeared on the wall is cosmetic and usually does not stop water over a period of time. I suspect you could argue it is a thin parging. Or a thin cementious product brushed on the wall. Drylok and Thoroseal are a couple of trade names of product that will work when placed on a wall "in compression" (water or soil exerting pressure against them onto the wall). I am not a fan of smearing stuff on walls except in the pursuit of art. Quote Link to comment Share on other sites More sharing options...
Jim Morrison Posted July 8, 2009 Report Share Posted July 8, 2009 Admittedly, I was born 100 years after his last great grandbaby got married, but, a la Les: I wouldn't burn too many brain cells on nomenclating the wide field of substances that might have been applied to the interior of a given foundation wall. If I wanted to note it, I can't imagine saying anything more than: "It looks like someone has applied something to the interior of the walls to help keep the basement dry."

Terence McCann Posted July 8, 2009 Author Report Share Posted July 8, 2009 I'm sorry guy's - should have been clearer. It's a white plastic material, about 1/8-1/4" thick. It's actually anchored to the wall with some type of a molly/lead shield anchor system. I want to say Celotex but I don't think that is correct. Now I'm starting to wonder if it's a regional type of thing. Quote Link to comment Share on other sites More sharing options...
hausdok Posted July 8, 2009 Report Share Posted July 8, 2009 Hi Terry, I'll echo what Jim and Les said. Yesterday I inspected a 97 year old bungalow with a basement where someone had applied some kind of stuff to the interior of the foundation on the uphill side. It was thick enough that I could push my fingernail into it and it was pretty durable but it was also blistering like crazy where the wall had probably been wet when it was applied. The stuff scanned wet and the drwyall applied over furring strip sleepers on the wall perpendicular to the wall that was coated was over 50% moisture in some places near that corner. Outside, a downspout emptied into an old concrete crock but the downhill crock on the next corner was bypassed because it was blocked. Obviously, there was moisture coming through that uphill wall despite the stuff applied. I suspect it's either groundwater, 'cuz the back yard slopes all the way to that back wall or that buried pipe that's receiving the roof runoff is separated below grade at or near that corner. Is it possible that what you saw was one of the Delta foundation waterproofing products? ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
Les Posted July 8, 2009 Report Share Posted July 8, 2009 Terry, Got it now! That stuff is quite common and used by nearly every waterproofing(gypsy) company around here. It provides a nice dark, warm and wet environment for mold. "Water comes thru the wall, is stopped by plastic sheeting, falls down into a trench, dirverted into a sump and pumped out." Slick system and keeps the basement dry! Or, we could just figger out where the water is coming from and control it before it gets through the wall. I have a bad attitude about waterproofing basements. Quote Link to comment Share on other sites More sharing options...
Terence McCann Posted July 8, 2009 Author Report Share Posted July 8, 2009 You got it Les. Any web site, that you know of, that describes the way these systems are installed? I've never been present during installation. Still trying to find the correct name for that white plastic covering. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted July 8, 2009 Report Share Posted July 8, 2009 Terry, It sounds like you saw something like Structo Glas, one of many brands of Sanitary FRP's out there.

John Bubber Posted July 22, 2009 Report Share Posted July 22, 2009 Many who install inside systems refer to it as.....bright wall. http://www2.snapfish.com/slideshow/Albu ... _111847456 They`ll attach it along bottom as in picture and sometimes against most-all of the wall.This 'bright wall sheeting' doesn`t fix/repair/stop water from entering. What this sheeting DOES do is hide/conceal water/moisture that is entering through the wall and it hides the actual CONDITION of the wall. When placed along the bottom courses of block walls it`ll conceal blocks that either have or can shift/bow inward or deteriorate.It hides mold,efflorescence on those blocks. It also provides a nice wet/damp breeding area between sheeting and wall, for insects,mold etc....it sure as chtt does! If you look at picture posted, the inside system and sheeting has not/did not STOP the water from where its STILL entering.Like most inside co`s, they do not correctly and honestly diagnose/identify where the water is entering. Click pic`s 11,12, see water/stains UP HIGH? Water is first entering through exterior openings in/around the CHIMNEY and,below ground THROUGH cracks/loose-cracked parging on the exterior of block wall...yep. Inside chumps want to HIDE stuff like this http://www2.snapfish.com/slideshow/Albu ... _111847456 http://www2.snapfish.com/slideshow/Albu ... _111847456 They want to hide bottom courses that are/have deteriorated and which THEY do not fix/repair. Someone thinks they know more then you call me,tired of the BS in THIS business. Mark Anderson 313-881-8035 Quote Link to comment Share on other sites More sharing options...
