I often have wet cars in my garage. The floor slopes slightly towards a drain in the middle of the floor. Can I use titles? Do you have special cut outs for drains? or should I just use vented tiles?

You can use our Diamond Grid-Loc Tiles in a garage where there will be water and a slope. Since these tiles allow water to flow between and under the floor, you don't necessarily need to use one of the Vented Grid-Loc Tiles, but you can interlock our Vented Grid-Loc Tiles with our Diamond Grid-Loc Tiles for that purpose.
