My parents property has a 4-5 foot tall concrete bulkhead around a portion of their cove. Over the years the bulkhead has developed a lot of gaps between the stones where concrete used to be but is no longer. We are worried that this is allowing soil erosion from the land side of the bulkhead and also effecting the strength of the bulkhead. We are looking for someone who can fill the gaps of the bulkhead with concrete. Anyone have a good contractor they can suggest?
