water leaking through floor tiles

Hello, is it possible for water to run underneath ceramic tile which has been glued to a cement subfloor? I noticed a small spot in the kitchen a few months ago, and figured my children or dog spilled something. what do we need to do to sort this problem? The house was built in 1974, so there is a good chance there was no moisture barrier used or it has since become ineffective. Pipes do break in concrete slabs and sometime water from outside can migrate under and through the concrete slab and up through the porous grout. If you are not in the area can you recommend someone who does this? Other products referenced in my last comment don’t have those limitations and they are made for tile applications to go over them. Or refrigerators can develop condensation that might be dripping on to your tile causing the grout to stay damp in that area. Once the tile was removed there was a significant amount of water underneath it. This is more problematic as you could develop microbial growth inside the wall. So by a process of elimination you try to narrow it down to correlate it to another event. I can’t speak to whether you have symptoms of a sink hole or not. The terrace is tiled with very beautiful natural stone. It might be necessary to remove the tile floor and repair the crack and install an epoxy moisture migration system to then bond the tile to it. I have read and investigated so much that I have a permanent headache. You’ll find that the leak is caused by a broken, cracked or dislodged tile. I bought a digital moisture meter and humidity is higher in the dark brown areas. This keeps water from migrating into the concrete slab that then can cause various moisture issues inside the house. Required fields are marked *. If the water shows up intermittently, then the source of the water could be from the showers or from the toilets. Dampness can also damage the structural integrity of walls. Sometimes you have to remove some tiles to help determine the source of the water and how to remediate the problem. He waited 20 to 30 minutes!! If this water oozes into the tile, the adhesive that bonds the tile to the cement will gradually deteriorate. There appears to be a slight bit of moisture and some mold between the barrier and the tile. Again you might need a professional to assist you in determining the extent of the problem and how to repair the problem and not just try to repair the symptom of the problem. The house is in Central Florida, and it was built in 1971. Water leaks or sources can be difficult to trace because they can travel a long distance. The water can flow from some other area to the spot under the tile, so you have to investigate with some trial and error methods. By fixing the gutters and downspouts diverts that water, but it doesn’t solve the problem of how that water originally was able to migrate under and into the house. Plus the tiles installed with a thin-set mortar need to cure for at least 14 days before they are submerged in water to assure adequate curing and resistance to the water. Just talked to a rep. where I bought the tile, and he said he is only aware of a Mapei product with moisture mitigation for showers — not floors with hydrostatic pressure pushing moisture up through the grout. Step Three: Dry Out your Home The first step in drying out your home is to make sure the humidity in the room is not too high, the temperature is low, and the air is circulating. Just covering the area with fresh tile without actually replacing the surface will leave behind moisture and allow mold and mildew to grow. Not as much as before, but I’m afraid of what will happen when it rains.

They only show up after a rain or some other event that subjected the property to water either by creating a higher water table in the ground or from a source of water from a higher level. Manufacturers like Mapei, Custom Building Products, and Laticrete have systems with moisture mitigation products and they give 25 year or more labor and material warranties if you use their system of products and install them properly per their directions and per industry standards. That means that the water table is near the surface of the ground or that a source of water from a higher location is draining toward and under your concrete slab. Hi….i live in a apartment 1st floor, almost 10yr old. At first I thought it was a leak somewhere but only certain places in each room where covered in water and none of the water is connecting to each other.. What causes this? The spots are a few feet away from the sink. When these pipes break, water escapes to the surface and causes the foundation to crack or warp. Thank You. There is suppose to be a vapor retarder membrane placed under concrete slabs and it should run up the sides of the concrete footings and slab. I don’t see any water in the basement below the wet area, in the structure or any surround I have areas. At this point what can I do? You have to dig a ditch around the house at an appropriate depth relative to source of water, Install a perforated drain pipe, with a pipe sock over it to keep growth from going into the pipe, into the ditch. We have seeping water under our kitchen tile directly in front of our refrigerator. You might have to go through a process of elimination. It isn’t coming from the exterior if you are on the third floor unless you have a balcony where water could be coming from it because it wasn’t constructed correctly. In between the floors there is the subfloor of the terrace (on which tiles were layed) , expertly applied waterproofing, then a metal layer that covers the entire area,then insulation and lastly plaster board. to this site, and use it for non-commercial use subject to our terms of use. Using an infrared camera and moisture meter might show the path of the water. I hired a lead detection company and they found and repaired two broken pipes in different places under the foundation. If it isn’t moving then you don’t have a leak. If water is coming through the floor tile grout joints on the sixth floor then the water is coming from the plumbing. Most natural stone tends to be very dense, so it is not likely that the water is traveling through the stone. Leaks in foundation walls are usually fixed in 1 of 2 ways: You couldn’t install a wood or vinyl floating floor that is subjected to moisture or it would fail. Then, the leak stops until the shower is used in the adjoining bathroom. That could make the grout joint waterproof in theory, but that would not make the tile assembly entirely waterproof. I have stopped using the bathroom that is behind that wall and put two humidifiers in the house because I’m very worried about mold being a first-time grandmother .FYI I never had any problems up until 22 days ago when the floor was done is it possible I have a leak in the bathroom because I did have one there 10 years ago,It was just too coincidental for me to believe that ever since the floor has been done I now have water in my tile grout. I have a slab house and in one room have radiant floor heating probably installed about 40year back. Custom Building Products has a product called CustomTech TechMVC 100% Solids Epoxy Moisture Vapor Control. If the water leak is coming through the ceiling from a second floor, try to pinpoint the upstairs source. If the tile was damp and then you removed it and the spot dried and did not become wet again, then that source of water stopped for some reason. While only a couple of tiles in your flooring may appear to be damaged, the entire surface beneath the floor is destroyed. Water always goes down hill due to gravity unless there is a siphon condition where it can go up hill due to a continuous flow of water. If water is puddling, you could have a hydrostatic condition where it is applying pressure to the tiles and could eventually cause tiles to debond. I would check the soil outside one of the exterior walls adjacent to this room and dig down and see if the soil is damp. Tile distributor sales reps probably are not the best source for technical information. The water hasn’t dried and has remained for several months now. It costs about $2 a square foot to install a vapor barrier, so you should first have the concrete slab and surrounding areas evaluated to see if there is a moisture problem. I would have a plumber come out to see if he can find the source. The ideal solution is to hire a construction forensic investigator to evaluate your situation, but that might not be practical cost wise. If we were investigating your situation, we would use our infrared camera to try to determine where the water source is coming from. Check the ceramic tile walls surrounding your tub or shower. Get an infrared camera to look for trails of cold/dampness. Otherwise the source of the water has to be coming from the other sources that we talk about in the previous entries. If not I’ll find a new plumber to come look at it again and try to reroute my water lines through the attic. Do you have any suggestions? Once the water source is found then you have to figure out what it will take to repair it to stop it. If there is water coming through the grout joint then it is coming from somewhere of course that is the challenge to find out where. We welcome your comments and If the tile was installed correctly the residual water/moisture should not harm the tile.

I’d be grateful for your insight – the folks at the tile stores give me blank stares when I discuss this issue with them. I like this post. I also had gutters installed and pulled flower beds away from the foundation as they suggested. Do I need a sealant in/over the grout? Now that the leak has been addressed, replace the water damaged material you removed to access it.

Or it being like two tiles in front of my sink (although I don’t see any other evidence of leaks anywhere) could it be a leak from my sink or bath tub? You don’t want to treat the symptom because that won’t fix the problem. It requires an investigation to intrusive search for evidence to lead you to the water source and a solution. You have to treat it … It doesn’t specifically mention that you can bond to it with a tile thin-set mortar. You can see if that will help. I’m guessing the rain is finding it’s way through cracks. If you are certain there is not hydrostratic water pressure that can be caused by a high water table you might get by with a product like redgard membrane or the ditra mat. If this water shows up every morning then you must try to associate it to some other activity that occurs every morning. We will re slope the outside area by the door to make sure water can’t come in again this way. Won’t moisture come up from there and also the efflorescence? Sometimes you can have a leak and you don’t see any wetness anywhere. We have no idea how long it’s been leaking while we irrigated the lawn; we have been watering the lawn twice a week for half hour clips for YEARS. You should hire a plumbing leak expert to verify if the pipes are leaking. and he applied ChemSeal which is a waterproof cement based coating for concrete on the foundation. He recommended at least 1/4 inch grout lines to maximize breathability, but said efflourescence will likely continue regardless. I'm attaching pictures to identify the leak. So my question is it water that was just on the floor from getting out of the bath and it got in the crack and it being winter and like 20 degrees, it’s not warm enough for it to dry up?

We live in a split-level house in the midwest that was built in 1975. Water can migrate in all directions of the concrete, but more so it will readily migrate downhill from the water source. Once the mortar has dried, mix a small amount of grout and apply to the tile to cover all the spacing between the tiles. Since you continuously have moisture in the grout joints and you have efflorescence that means water is migrating up through the slab in that area. When you step on the tiles you force water up through the grout joint. 99 percent relative humidity readings is practically a wet surface if in fact it was tested per the ASTM F2170 protocol. So it never dries out as it should and starts giving a musky odor. I waited 6 weeks to insure the leak was fixed before putting things back together. Tile installations are more resistant to moisture, but you can develop efflorescence staining, but it can be removed. So over a year later we noticed that when we step on this one tile, water seeps out a little through this hairline crack in its grout. When it comes to water damaged vinyl flooring, the limited warranties of most of the flooring manufacturers protect them. Could it be related to the washer drain? Oh my gosh I am a bit surprised to find that this issue is so common. They can often cause damp and mould within surfaces behind tiles, and can even threaten the structural integrity of walls, so it’s important to tackle the issue at the first sign of a leak. You mentioned epoxy vapor barrier on other questions; but asking in local stores, they say it is not necessary if I put tile. The key to stopping the water seeping into and from the brick joints is to stop the moisture. Recently, after 2 days of heavy rainfall, water started seeping in from the joints between floor and wall in multiple rooms. If it was the toilet I would think I would see water directly around the toilet but I doubt it’s about maybe a foot away from toilet & maybe 2-3 feet from shower tub. So I have a small water leak on the hot water side of this faucet. Sometimes hydrostatic conditions are periodic. Please help! I’d like the floor grinded/prepped and then tiled. The solution is that the porcelein tile will keep the moisture from underneath at bay. When I turn on the sink, water seeps up through the grout between the tiles, as well as through the cracks in a couple of damaged tiles. All information is provided "AS IS." If water is seeping through the grout joints that could be an indication that you have hydrostatic water pressure occurring. If water gets behind tiles then it can harm the adhesive holding the tile to the structure. Foundation walls crack and leak when water soaks into the walls and eventually begins to drain inside of your basement. When the tub is filled with water, or there is weight in the tub, it can cause the tile beneath it to flex and compress and cause the tub to settle. He said I had a high water table . Once it is saturated it doesn’t absorb any other moisture and doesn’t cause any significant pressure or expansion in concrete slabs. In the kitchen there are three areas that the grout is bubbling when we step on the child a line in front of the refrigerator which go to the back door and a line in front of the sink sink.
