Re-lay Paving Stones

Description

I need to re-lay existing paving stones in a greenhouse/pavilion. Area — 47 m². Currently, there is geotextile and insulation (XPS foam) under the paving stones. The foundation does not need to be disturbed, excavated, or completely rebuilt. This is not a full-cycle job — I only need to level the surface above the existing base. I will handle the removal of the paving stones myself. Requirements: * Level the surface over the geotextile; * If necessary, add and level sand; * Lay the existing paving stones firmly at the same height. This area is being prepared for a framed pool, so a maximum flat surface without pits and waves is important. The work will take place inside the greenhouse.
