Beads of silicon on the cement, correct? This is a great idea. We pick ours up after each use in order to park our cars in the garage, but I'm thinking the silicon will hold up just fine.We use ours on concrete as well except the underside of our mat is smooth.
We started with bricks on the corners but it would eventually go crooked. Went to HD and bought clear silicone and laid out some thick beads and let dry. Has been gripping Great!
