Find me a rubber or plastic outdoor mat for rainy season

I have been looking for a rubber or plastic mat to put near a damp place on the floor. Rain water falls there and I want the mat to have some drainage mechanism. I have seen the artificial grass mats on Amazon and Flipkart. Alos there is a rubber black mat with big holes. Does anyone know if there is a mat available that has small holes and also thick so that the floor water does not touch your feet?
