tanking

Currently renovating my bathroom, and while ripping the tiles out ( 2 layers of tiles) I noticed the internal walls are not the standard stud-work and plasterboard. They are very thin like a cardboard material down the middle so I have nothing to mechanically fix new plasterboard to. My initial...

Hi all, Hoping you can help. I’ve been tiling my shower and was ready to grout before putting a massive scratch on one of the tiles. I went to remove the tile but it’s taken the tanking and some of the cement board with it. As it’s in a shower, I want to do what I can to make sure it’s not going...

Hi all, I'm back for a bit of advice please. We got a builder in to waterproof our basement and have got a real mess on our hands. A bit of a long story.. We have a narrow Victorian basement that is pretty damp that we wanted converting into a dry utility room. We got some surveys and quotes...

Hi, all I have just finished my wetroom and tanked all areas, to my understanding because this is a wetroom, therefore, all areas should be tanked. However, I have created a large concrete step that is spirit levelled and my worry is if I tank this area then should any water ingress via...

Hi All, Hope you can help. I am just wondering whether I should backer-board the concrete block bench in my wet room, applying it with a tile adhesive. Or can I tile directly on top of the concrete block work? I worry about moisture or cracks within the concrete block/to tile directly on...

Hi guys, I am in the final process of completing my wetroom prep before tiling. All that is needed is the waterproofing and my mortar bed slope to the linear drain. I have applied waterproof backer boards, now I am ready for tanking/waterproofing. My question is should I fully Tank my backer...

Just fitted a large and heavy stone shower tray onto a mortar bed. I forgot to run silicon sealant around the edges, before tanking with liquid latex and adhesive repair tape from Aquaseal. The tape overlaps onto the shower tray, making a waterproof seal all around it. Do I now need to cut the...

Hi all, Thanks for your thoughts on this: I've used cement board and then BAL tanked for shower walls before. I've got someone coming in to redo our bathroom who is suggesting he'd use Aquaboard: https://www.siniat.co.uk/en/products-and-systems/products/internal-boards/10-aqua-board. I've...

Hi, Guys would like your advice and opinions please concerning my wetroom renovations. I have stripped the walls back to bare brick and removed the previous concrete screed. Sadly, the previous screen was done by someone who didn't slope it correctly allowing water to flow out of the wetroom...

I have a garage which is built with the walls sitting on the concrete slab, with a DPC at floor level, single skin brick. Parts of the walls are below ground, when it rains water seeps through the DPC. I've dug out and exposed one side and will cut back the DPC as close to the brick joint as...

Hi, Contractors are completing my basement and tanking it all (Delta Membrane). I am installing metal stud walls to the edges of the room that will be insulated but only plasterboarded on the one side, so I am concerned about the strength/possible felixibility of the wall as it will be approx...

Hi, I did have an account on here a few years back but can't login.. So I'm converting our basement into the babies future playroom but I'm stuck on floor choice. My current substrate is the original brick type floor which was possibly laid when the house was built c.1870. My main goal is to...

Hi there, new to this forum and grateful in advance for any advice. Have a property that used to be a pub, so has a large cellar/basement, and looking to make the space a bit more usable by tanking the walls and floor to create a space for storage that's a bit dryer. The walls had a layer of...

Bear with me, this is a long story: This the 5th time I've had this work done, and no body seems to know the cause. I have a bath mounted shower, which comes off a bath mixer tap which come from the floor. (THERES NO PIPES IN THE WALL). This was all originally fitted with new tiles after I...

Hi.. i'm sorting out my bathroom in my converted Victorian terrace flat to fit new shower etc, few damp issues which im in the process of sorting slowly. A company quoted for the following to be done: 1) To apply anti-sulphate onto the brickwork. 2) To plaster the wall with sand and cement...

Hello, I am looking for a bit of help with a tanking project. I have a small storage area under the front steps (apx 6ft x 3ft), which is mostly below ground level (I expect it’s the old coal storage area since the house is a Victorian terrace). We have had some problems with water ingress and a...

Hi I am planning on building a one storey extension to the rear of my garden flat which is on the ground floor of a victorian terrace house in london. There is an existing sunken patio to the rear of my flat and there is a 1.2m high retaining wall holding the raised garden. The extension I want...

Evening all, This issue has just thrown another curveball which has made me sign up to here to try and get some opinions. I've got an old victorian terrace down in Portsmouth and looking to get the basement tanked and used as a suitable DRY storage space. Thought I had it sorted when a builder...

Hello all I'm currently damp proofing my basement. I have hacked off the plaster and intend on applying Synthaprufe to tank the walls. The masonry walls aren't in great condition, is it advised that I stabilise the walls before applying the Synthaprufe or is there no need? Also, there are a...

Hi all, welcome to my post. The front room of our house has had damp issues since we bought it in early 2012. We then had an large extension later that year, although the front room with damp problems was not touched back then due to finances at the time. Our place was originally a cow shed...
