The current paving method is to choose smooth tree pit stones for direct paving, and also requires renovation, such as repeating the polishing process, which is costly. The correct method is to select the effect of the smooth tree pit stone, buy a rough panel, then pave it, use a level to level it, and carry out maintenance. This can greatly reduce costs. This method has been applied in practice internationally, but the correct plan has not yet been formed domestically. The main issue is the disconnect between the procurement and construction of tree pit stones, and the lack of consistency in concepts. The higher costs are entirely borne by the purchaser.

Despite its many advantages, this method is only suitable for granite stones with small color differences and no texture. Many textured stones have layout issues, so traditional methods are still used for processing, arranging them in order, and then proceeding with construction.
