If you have been mixing concrete or laying it, there's a good chance that you have tools and wheelbarrows that are caked in concrete. This concrete is going to be difficult to remove, but it is also frustrating to dispose of it without harming the environment. If you just hose off the wheelbarrow and let the concrete washout run into the sewers, you might harm the water supply. Here are some tips for getting your concrete out easily and disposing it responsibly.
1. Redirect Your Washout
The first thing that you should do is redirect your washout to a grassy area. This is good because it will keep the washout from flowing into the street where it could get into the sewers. If you redirect the washout into a grassy area, you will be able to allow the liquid to evaporate and be absorbed the ground in day or two. Then, you can collect the hardened concrete particles by hand or with a spade and throw them away. Once the concrete is hardened, it can safely be disposed of because it won't dissolve again and potentially affect the water supply.
2. Catch Your Washout If No Grassy Area is Available
If you are working in the middle of a parking lot or some other area where there is no grassy area available, then you are going to need to catch the washout before it actually hits a surface where it could drain away into a sewer. Your best bet is to purchase disposable tin pans that are going to be wide enough to cope with the washout splashes. Put a large, preferably multi-gallon, bucket on top of the pan and try to redirect your washout into the bucket. Once the concrete hardens, you can remove it from the bucket and throw it away, or simply throw the entire bucket away. Throw away the tin pans that you used to catch any splashing.
3. Block the Sewers
Finally, if you can't do either of the above, block off an area so that the washout will not be able to travel far. Block any sewers or anywhere the washout could escape. Then, wash off all of your tools and receptacles. Once you are done, allow the concrete to dry slightly and remove the residue with shovels or spades to dispose of properly. Remove your barriers and unblock the sewers.
