What materials can be made of the floor on the terrace
Wooden floors. Even a pine tree treated with antiseptics and protected by paint and varnishes can last for many years.
And if you choose a terrace pineboard with heat treatment or impregnated, then the service life of such floors will be significantly higher. The larch has even higher indicators, but it is also much more expensive. From domestic breeds, such solid varieties as oak or beech can still be noted, but this is a different level of flooring. And exotic species from Latin America belong to the elite class, their density in Brinell is the highest, and some can withstand high humidity even without protective treatment.
