Devices like ground-penetrating radar (GPR) and ultrasonic testing equipment can see through concrete. GPR uses electromagnetic waves to detect structures, voids, and other anomalies beneath the surface. Ultrasonic testing employs sound waves to assess the integrity of concrete by identifying flaws or inconsistencies. Both methods are valuable for construction, engineering, and maintenance applications.

Depending on what kind of sealer you use, the concrete should be completely dry and firm enough to walk on.

Check out the products as you go and see what might work best for you. See the attached link.
Oxygen cannot pass through a concrete wall in significant amounts because concrete is a dense and solid material. While some gases can diffuse through very small pores in concrete, the rate is extremely low and generally negligible for practical purposes. Therefore, a concrete wall effectively acts as a barrier to oxygen transmission.
Sunglasses are a concrete noun- you can touch them. They are, of course, not made out of concrete. They would be very hard to see through. And rather heavy.

Yes, "teenager" is a concrete noun because it refers to a specific group of individuals who are in their teenage years.
