You are really brave to finish a basement with a known moisture issue. I for one wouldn't spend a penny on finishing my basement until I have seen it go through a wet season without failing. Not telling you to stop but would warn to slow down. Get your framing/electric/plumbing/whatever done and let it go through at least 4-5 months before finishing ...

That is a major issues, especially on a new home. Call the developer. They have a right to repair it before you pursue legal options.

While you probably could, this wouldn't be a good way to try and match a color. It would likely effect the setting performance of the concrete and you'd never match the color of the paint. On top of everything else, it would be much more expensive than the alternatives - all you really need is the pigment and everything else that makes up the paint is ...

There is a method that can solve both of your problems. I’m not sure how to translate it in English but it is called something like "polishing up to a point of black gloss“. This method makes the concrete waterproof and also brings up the color like you wanted. Back in the past this is the way people made their floors waterproof. Basically you polish ...

If, after completely cured, the paint still exhibits the same poor adhesion characteristics, you will unfortunately have to scrape or strip all areas that are unsound (probably the entire coating). You must then properly prepare the surface (sand, sand, sand) then repaint.

Just use the plain cement. Mix water and cement and it should be half solid

no it's not the 0.5inch stones and it was so-post to be 1:1 1/2:1 that is 1 cement,1 and a 1/2 sand and 1 gravel and the concrete need water not too much but should be moderate for it to make the cement react rapidly

This problem is termed as concrete spalling. You can fix it without replacing the entire driveway. Before you begin it’s important to power wash the surface. Use a stiff broom to brush the entire surface. Shop for a cleaner concentrate easily available at a hardware store. Next, inject your concrete into the injection hole. You must not go over 40 psi. If ...

You can use a natural sponge to make concrete like shadings. Use a light touch and dab the sponge. Turn the sponge often so you don't get a regular pattern. Practice first on some cardboard. You can start with either your darker shade or the lighter, see which you like the best. Go back over what you have done with a dry brush or rag to soften your work ...

Products like Dricore are designed for scenarios like this. Basically its a piece of plywood with a rubber base. The base has channels in it to allow small amounts of water to run under the floor. These work in scenarios where a bit of moisture is unavoidable. The downside is the cost and can run $2-5 per square foot, but an upside is extra insulation on ...

A plastic or EDPM rubber sheet will work, if the flooring installers don't puncture it. That pretty well limits your flooring to a floating floor, but that's not a great impediment. Nothing painted on to the inside of a concrete structure will stay put if water is coming from the outside (more commonly seen as failed attempts at "waterproofing the inside ...

Heavens no. The cracks will just go right through the new concrete.

Sure - many people build new wooden or "plastic-decking not-wooden" stairs over old, excessively steep concrete steps like that rather than rebuild the concrete ones, as much to make them more reasonable in rise/run and landing area as for fixing the basic steps. In many ways it is easier if you demo the concrete ones first, (other than the concrete demo), ...

Sounds to me that you have covered all the bases. Maybe you should pay attention to few details: Connecting old and new concrete; you have mentioned that you plan to do it, make sure that they are well stuck inside of old concrete (you drill slightly smaller hole than bar and hit the bar it with hammer when placed inside a hole. Also, you can chip old ...

Another option may be an angle grinder with a wire wheel cup.
