Hey. I am thinking of installing some grouted riprap as an energy dissapator for water coming out of a bunch of gutter drainpipes and a culvert pipe at a house. Currrently the pipes are discharging into a wooded ravine at the side of the house. The rainwater has eaten away a huge chunk of the slope. Anywho, I know what the end product needs to look like because I have seen it on plans before. But I have never actually done it. What is the process? Once I get the dirtwork done, can order up some grout from the local concrete batch plant and pour a bed of that, and then hurry and set all the riprap in the grout. Help me. Thanks.
