I have a customer that I put in some drainage fro last year. Nothin' fancy, just some perforated pipe, silt sock and a stone bed. Anyway, the hurricane last year pulled up a tree and damaged the pipes for their pool. The pool contractor came in and removed the root ball and repaired the pipes. However, in the process they put deep ruts in the yard and tore up about 25' of the drainage pipe. I know what it will take to repair the drainage since I put it in, but I need help pricing the repair of the lawn. The ruts are 1' to 3' deep in clay soil and the area is about 40' by 25' that is damaged. With about that with serious ruts. I have good access to the site all I have to worry about driving into the pool. I was thinking of using a Dingo with the tiller attatchment, but I'm not sure it has enough as*. ANy suggestions would be great.
