Confirm the paving layers first
Stone, brick and other finishes have different thicknesses. Confirm tray depth using the paving and bonding layers, while allowing for the load-bearing structure and finished level.
Balance appearance with access
Paving must not obstruct maintenance. Consider lifting points, handles, sections and filled weight when confirming drawings.
Check site dimensions before installation
Check the opening, paving layout and drainage slope. Build foundations and bearing surfaces according to installation instructions. Final dimensions must follow the confirmed drawings.
