Water seeping up through the grout in between tiles on a tiled floor can be caused by several factors, including:
Cracked Grout: If the grout between the tiles is cracked, water can seep through the cracks and reach the subfloor.
Loose or Damaged Tiles: Tiles that are loose or damaged can allow water to seep through the gaps and reach the subfloor.
Poorly Installed Tiles: If tiles were not installed correctly, with inadequate adhesive or a poorly leveled surface, water can seep through the gaps and reach the subfloor.
High Water Table: If the area where the tiled floor is installed has a high water table, water can seep up through the grout.
Plumbing Issues: A leak in the plumbing system, such as a damaged pipe or loose fitting, can cause water to seep up through the grout.
Flooding: If the area where the tiled floor is installed experiences flooding, water can seep up through the grout and reach the subfloor.
1. Ground water buildup seeping up through tiles
2. Leak in pipe in wall; water being directed beneath floor coming up through porous or hairline fractured grout

== == Water can very well find it's way through the floor. It is usually at areas where the tile meets a vertical area at a shower or tub. Movement can occur in these areas. It is best to caulk joints such as these, instead of grout. The caulking will flex, but the grout will crack and allow water to penetrate.
First you lay out all the tiles with spacers adhering them to the floor, then you grout between by scraping across surface of tiles. Then just wipe clean. The grout is like a concrete mix & will harden.
You have to rake out at least the top 3mm of the existing grout first. Then you can re-grout with an appropriate grout as normal.
You can. It is less gritty but it works. Edit - While this is true, it's important to understand the wall grout is designed for thinner grout lines, so if you use it on the floor, make sure your grout lines are thin. Otherwise, the grout will crack.
Improper installation. You must install cement board over the sub floor before you tile. If the tile was glued to plywood which is not waterproof, the plywood will absorb moisture which will cause the grout to crack and deteriorate
by adding acetone to it
You can but it wont look very nice, if you use grout you get a smoother joint and you have lots of color choises.
Grout should usually be white or contrast with the tiles, but it truly depends on your preferences.
You risk having the loose tile cause the grout to chip out. Find a way to secure the tile first.
Sadly, if you are looking to fix the tile with the grout, there is none. If you are looking for something that will not crack because of movement, a high end epoxy grout.
Yes, you can use unsanded grout for floor tile but you'd only want to use it if the grout lines were 1/8" wide or less - like for granite or marble tiles.If using those, be sure you have a pefectly flat surface.ANSWER:You never want to use sanded grout with marble. If the marble has to be restored or re-polished for any reason the sand in the grout with act like sandpaper on the stone.
