Sep 09 2019 When using sea shells for landscaping for example water can travel between the crushed shells and into the soil rather than puddling up As long as the base below the soil has good drainage as well such as by laying down a base of crushed concrete water will pass through the soil and the base This prevents the yard from becoming a muddy mess If the shell is cracked or chipped or there is a hole but the overall integrity of the shell is reasonable the snail will probably recover If the shell has split into pieces but still covers the body it may even survive that Minor body damage can be healed also However snails that look really mangled such as the body has been crushed
