Hi all, I need help, please. I am renovating a house near the coast in Spain. It has a basement where the floor is just concrete and the walls are concrete blocks, part of the foundation. There is only a 1.5M door and 2-3 little air vents.

1. What materials could I use to load up the walls to look straight and livable? E.g. do I need a metal mesh? Any humidity materials?
2. What are the steps to ensure there is no high humidity, besides good ventilation?
3. Any idea how to turn a concrete floor into a smoother area without a pick axe and without raising it more than 3-5 cms? I don’t need it perfectly straight.

Any examples would be much appreciated. Wish me luck with this projetc. It will be a back breaker.
