concrete

Hi I've opened up my fireplace and installed a lintel ready for the installation of a 5KW, 85KG log burner. As I got down to floor level I noticed it was very damp, so I removed the quarry tiles and found soil. I am intending to hammer in some hardcore lay some DPM and fill the 3 inch void...

First post so I will introduce myself ,I am a tiler who is currently having an extension built by my neighbour who is a general builder/ brick layer We are very early in the build and have just had the foundations dug out the builder had to go deeper than usual as we had a sewer main running...

Hi guys, Hope you're all in good form :) My latest project in the house is leveling (and then covering with laminate flooring) my garage concrete floor. I think the best bet would be leveling compound as it's pretty uneven in parts. I have a couple of problems though: (Please see pictures...

I have lowered my slab by around 500mm and this has meant that the foundations are now slightly above the top of the slab by about 50mm around the doorways. The plan is to put 50mm insulation and then 50mm of screed on top of the slab. Is it preferable to cut or grind the foundation concrete...

I'm in the process of prep'ing a concrete sub floor. I just want to make sure I've done everything correctly before the self levelling. The concrete has quite a few cracks in it, which are also high points. So I've been grinding these down which has opened them up a bit and they will now need...

Concrete has a R-value of only 0.08 per inch. (8” = .64) 8” concrete block has a R-value of 1.11 It’s essentially the same material, isn’t it? Does anyone know why there is a difference?

Problem: Tiling a kitchen floor. Half is covered in bitumen (from parquet floor). Half is a new concrete slab. There is a 35mm level difference across the floor and is fairly lumpy. Possible solution No.1?: Use latex self-levelling compound such as arditex na. BUT: I am slightly worried...

I am soon to be fitting solid wood flooring and will be doing this with hidden screws in the tongues of the boards, so I will be using a ply sub-floor on the concrete. (I did this with the other room, same boards, and was happy this way) I would like to also insulate under the boards but I only...

Going to be renovating my outhouse and turning it into a bar/reception area. Thinking about putting plasterboard on the walls (concrete) using plasterboard adhesive but I just wanted to know if I can stick it on the wall once it's been painted with damp proof membrane? Also need some advice with...

I have removed some seriously ugly and thick floor tiles for my kitchen - area 4metres by 9 metres. This has left the adhesive behind in 'blobs' with multiple holes etc. I want to put down vinyl and need to level the floor, the current situation leaves me with level changes of 5mm plus and the...

I'm in the process of building a new front Doorstep. I'm planning to build formwork, before pouring a Concrete foundation, then laying stone Treads and Risers onto a Mortar bed. There is an existing structurally sound cast-in-situ Concrete step in place that has been there for almost 100 years...
