Answer:
I live in a sandstone-rich area of Scotland and my house in fact is built of sandstone, as are several walls near it. There is also a sandstone quarry outside the town. It is basically a 'stone' (if you could call it that) which is made of sand, crushed together thousands of years ago. If you scrape it, sand comes off. If I wanted i could scrape my way into my house with a spoon. Throw a sandstone block on the ground and it will split into several pieces easily. Cracks do not usually stay in a sandstone block due to its nature - a crack will normally just split the block in 2. So to answer your question, sandstone CAN have cracks, but not big ones or it will just shatter into bits. Basically, no.
