Protective caskets and sealers do not prevent the body from decaying. No matter what type of casket you're placed into the ground in, you will have infiltration of moisture, insects, roots, etc. into that casket. There is no casket that is actually going to protect the body from the elements and prevent it from decaying once it's placed in the ground.
