Please help! Just had the the kitchen of an older (1989) house that I bought demo'd and took up the old flooring. The electrician & plumber dug a fairly large trench across my kitchen slab to move the electric and plumbing to my future island. Is there anything that I can have the trench filled with that will dry and process faster so that I won't have to wait a month plus to lay my new engineered wood flooring? I am in a catch 22 situation- the kitchen installer wants to wait for the floors to be done and the floor installers say ordinary concrete could take a month or more . I won't say money is no object but I am willing to spend the bigger bucks if there is a product that will help get the job done much quicker. Thank you!
