I've got a job that involves 'shoring up' and preventing the sides of a natural pond collapsing. The earth on the pond sides has been breaking up and encroaching on the lawn (see photos). The pond itself is a 'balancing' pond with water coming in one end of the pond via a pipe (from an adjacent field) and leaving at the other via another pipe. The owner has had the property for just over one year. What's the best way to 'shore up' the sides of the pond to prevent further collapse and if possible to infill the earth that has been lost to date? Any suggestions for enhancing the overall look? Thanks. JG.
