YES!
YES!!!!!!! It has to be diluted with water or it will eat away at the surface. I know from personal experience. This is very strong and corrosive. and should never be used full strength unless you are trained in using. Muriatic acid is an impure form of hydrochloric acid. It is extremely corrosive and it is advised that you use a face shield, and use in a ventilated area only. The fumes are very corrosive and can cause irreparable lung damage. Improper use can release chlorine gas, a gas used in WW I by the Germans. If the purpose is to clean brick, or etch concrete it can be diluted, and should be. The recommended concentration to clean brick is at least 10 parts water to 1 part acid. If the acid releases a very strong fume on opening use 15 to 20 parts water. It also reacts with various metals to form an explosive mixture with air.
Even the driest basement has some level of moisture seeping through the concrete due to capillary action. For that reason paint, sealants, primers and waterproofing coatings applied to the slab don't usually work. They do nothing to keep the moisture from infiltrating the concrete. They simply trap it behind the coating.The moisture builds up and eventually, in most cases, the paint peels off. According to Building Science Corp and the U.S. Department of Energy, basement walls and floors should be allowed to "breath" and the moisture allowed to dry into the basement.

Between 3200 and 3600 m/s, the closer together the particles are in a substance are, the faster sound can travel through it. This is why these values are much higher than the 343 m/s, the speed of sound in air.
The underground place is right over the traintracks to the left, the second building on the left, go in there and then there is a couple trainers and what not. You walk down straight and about halfway through there is a right turn and a little blue door, that's where you use your key :)

Try UGL Dry-lok.
You can use muriatic acid to clean or etch aluminum. Do not let it set too long or it will eat through. Use caution since muriatic acid is very caustic.
No. That would be very dangerous. In the US, pre-drill a hole through the framing and into the concrete with a masonry bit and install what is referred in the trades as a "Tapcon" screw. The concrete should be penetrated a minimum of 3/4". Ask for Tapcon screws at any hardware or home improvement store, and follow the instructions on the box.
The only sure way is to dig down on the outside and seal it from there. Water will tend to push out anything you use on the inside. If it was me, I think I would use some of the expanding foam in a can. If you can get the nozzle between the pipe and the concrete it should seal it. Finish the inside with some concrete patch caulk.
Do you have problems with frozen pipes? Does someone live in the basement? You won't lose much heat through the basement because heat rises.
No
reinforced concrete
One of the best ways to avoid water in the basement is to avoid water outside of your house as it may sink in through cracks and holes in the wall and into your basement.
Steel reinforced concrete is concrete with rods of steel running through it.
radio and tv beams can pass through concrete as x-rays pass through the body
