Lift up the concrete statuary, with the help of a friend, and place bricks or wooden blocks underneath it to elevate it above the soil. The bricks or wood blocks only need to be 3 to 4 inches high.
Examine the statuary to see if it has any birdbath areas, bowls or vases that may collect rainwater. If so, pour out any existing water.
Place balled up rags inside the concave cavities of the statute to collect any moisture that may seep in.
Place a plastic trash bag over the concave areas and secure it with waterproof masking tape or rope. This prevents water from collecting in these spaces and freezing which can crack the concrete.
