Are the tiles affected by water or heavy rainfall in any way?

Due to the gaps between the wood and the specially designed frame base, any water drains away quickly and freely. No water remains trapped or in extended contact with the wood. Some competitive products on the market will channel water in a certain direction and the tiles can only be removed from the edge of the deck. Often times we have customers who have had bad experiences with hardwood decks, especially on roof decks. This is usually because of high moisture buildup on the underside of the decking(between the sub floor and decking. This will warp and twist the wood as the surface dries but the underside remains moist. This is called cupping or checking. Our tiles will not cup because of the adequate air flow under the tiles and under the wood. All moisture and heat are released through the tile preventing the wood from checking. In addition the wood slats are not long enough to experience bowing and twisting. This is a great advantage over traditional hardwood decking.
