Is concrete waterproof?

Concrete is not 100 percent waterproof in the classic mix. They can also absorb moisture to a certain depth if they are exposed to it permanently or under high pressure. The water resistance of the concrete also depends on how well it has already dried and hardened.

Is epoxy as strong as concrete?

Compression strength is the capacity of a material to withstand a constant load, or to resist compression. Standard concrete is typically 4,000-5,000 psi. Whereas, epoxy systems from Simon Surfaces typically reach at or above 10,000 psi. It can be two-to-three times stronger than concrete.
