Then draw a circle to the floor tiles after shaving, you need to find the joints of the water pipes below, and then re-pair all these joints, and then seal the treatment, after processing and then buried the water pipes concealed into the ground, and then use the plugging treasure or cement mortar for smoothing, repair the waterproof and then restore the floor tiles.
