Decompostie Granite

[Residential Recreation]

I have a client that wants a cheap way for a patio in his backyard the demensions are 15' by 20' i normally do brickpaving for patios and since i usually work alone I have nobody to trust floating that much concrete all at once This is in northern indiana and i can guarentee that the concrete will crack i like to give some sort of warrenty on all of my work i was wondering if decomposite granit would be a good solution and how long it would hold up to these elements so far i know of no one doing this in this area
