Do you have to use non-slip bricks on the shore of swimming pool?

According to many years' experience of elegant swimming pool bricks, anti-skid bricks are needed on the shore of swimming pool, and there are no anti-skid products at present. Once the water comes into contact, it is easier for athletes to slide. Regular swimming pools generally use anti-skid bricks, and some gyms require anti-skid coefficient to reach R 1 1, so swimming pools require anti-skid bricks.
