Pavers should be laid when?

Pavers should be laid when?

• A. After grading
• B. After soil preparation but before grading
• C. Before soil preparation and after grading
• D. After soil preparation

Answer: (D)

Pavers need a stable, well-drained foundation, which only comes after the soil is prepared. During soil preparation you clear debris, loosen or compact the subgrade, and establish the final grade with the correct slope for drainage. Once that surface is ready, you install a base layer and bedding sand, then lay the pavers. If you place pavers on unprepared soil or before the grade is set, they will settle unevenly, crack, or shift as moisture and loads affect the soil. So they are laid after soil preparation to ensure long-term stability and drainage.
