What the best way to seal concrete?
It all depends on what the concrete is used for. If it's a footing or foundation that's in direct contact with, and buried by, surrounding earth, you can use heavy duty (6 mil) poly sheeting, or glop asphalt/tar all over it. If you're talking a sidewalk, driveway, stairs, or some such visible surface with foot or vehicle traffic, you want to use a penetrating sealer---concrete sealer, or Thompson's Water Seal.

What causes big cracks in the sidewalk?
Big cracks in the sidewalk can be caused by a variety of factors, such as tree roots pushing up underneath the concrete, soil erosion beneath the sidewalk, or the natural settling of the ground over time. Changes in temperature, especially freeze-thaw cycles, can also contribute to cracking by expanding and contracting the concrete.

What would expect to happen to a sidewalk over the course of years when rainwater continues to soak in to concrete and freeze?
If water is allowed to get into a concrete sidewalk and not allowed to drain and it freezes, the expansion of the water/ice as it crystallizes causes the concrete to crack. If more water settles in the crack and freezes, the crack gets bigger. Each year the increase in the size of the crack is greater because a greater amount of water can fit in the crack, and a greater amount of water has a greater amount of expansion when it freezes.

You want to pour a concrete slab over the existing slab do you need to do any preparation or is it best to remove existing slab?
It would always be best to remove the existing, but sometimes it is cost prohibitive. To pour a slab over an existing slab, especially if it is uneven or fractured, will cause weak points in the new slab for various reasons. If you're going to do it anyway, try to make sure the new slab is minimally 3" thick at the thinnest point of the formed area. Commercial solutions are available also to aid in the adhesion of new concrete over old. These products are available at most home stores.
