VEVOR Interlocking Drainage Mat, 12” x 12” Modular Interlocking Cushion, 40 Pcs Splicing Drainage Mats, Non-Slip Gray PP Drainage Floor Tile and Shower Mat, for Garage, Garden, Kitchen & Outdoor

Can these drainage type tiles be used together with your regular (non drainage) tiles? Will they all snap together?

Do these have a non skid bottom? I’m looking to create a walk way on smooth concrete but don’t want to completely cover the floor with this.

Are these made out of rubber or hard plastic?
