True, but that doesn’t mean it can't be damaged. And damaged concrete can create damaged equipment.
Concrete floors are not immune to damage by impact, abrasion, harsh chemicals, and thermal shock. Many warehouses utilize forklifts and other heavy equipment that cause damage to concrete surfaces. Possibly, you have had to relocate equipment within the work area, and it has left behind holes and other damage.
Cementitious repair mortars, epoxies, and a host of other materials can patch and repair concrete surfaces.
Even if your concrete floor is in great shape, a floor coating installed over the top of the concrete, leaves the floor covered, protected, and looking new again.
