My wife and I recently had our entry way, hallway between entry way and kitchen and entire kitchen floor redone using ceramic tile. The tile is installed using thinset on 1/4" cement board which is screwed into 3/4" tongue and groove OSB which is nailed and glued to the original 1/2" plywood subfloor.
So, I haven't brought a pin into the house or out of my basement since the tile was installed 3 months ago. However that is about to change and I'm concerned that an Escalera dolly weighing close to 100lbs (has some attachments) and a 300lb pinball machine may cause the tile to crack or chip. The tile goes right to the edge where the basement stairs begin so the two small Escalera stair climbers will grip the tile close to the edge with 400lbs, 500lbs with a WOZ weighted game. I will have to move a pin on tile in the kitchen, hallway and entry way to get it in or out of the house.
A couple options I can think of.
1. Install an elevator in the basement to the first floor. Wife said no. Just joking, lol.
2. Get 3/4" sheets of plywood and put them on the tile to help support the load of the game and avoid cracking the tile. One piece would go right up to the edge of the tile where the stairs start so the Escalera would grip that instead. I'm not sure if I can get away with 1/4" or 1/2" plywood instead?
3. Procceed as is and hope the tile doesn't crack. Sounds risky but maybe the tile can handle the weight? The Escalera wheels are rather small and will go across grout lines on the tile. I thought about getting the big wheel attachment but I would still have the issue with the small stair climbers resting on the tile floor near an edge.
Any suggestions / tips?
