1. There are two types of sinks: under-counter and over-counter. The contact part between the under-counter basin and the countertop is a flat contact surface, about one centimeter wide; while the above-counter basin is generally curled, and the edge after this treatment will not It's a plane, more or less radian.

2. When the under-counter basin is processed, the sink is generally buckled to the bottom of the table (the hole has been opened and the edge has been ground), the contact part is filled with sealant, and then a plurality of pre-cut stone strips are bonded with marble glue To the four sides of the sink, it plays a role in fixing the load-bearing. Of course, the more it is, the stronger it is.

3. After the marble glue is completely solidified, it can be used for water storage. The problem you mentioned may be due to the poor processing level, or the purchased basin is not suitable for processing into an under-counter basin! If the basin is changed on the table, the opening may not be suitable, and it needs to be re-opened.
