Trucks and other equipment that are used for any sort of plastering, concrete, cement, and stucco work all need to be washed after use. If they are not cleaned, the mixtures they were used to create harden, and then the trucks and tools become utterly useless because you cannot safely remove the hardened substances. Additionally, there are always environmental concerns when washing these substances off of equipment and out of trucks. For these reasons, if you rent any sort of this type of equipment and need to wash it before you return it, you will need to purchase some concrete washout solutions too. Here are some solutions you can buy that will also help you stay EPA-compliant and prevent your project from legal interference.
Berms are like bathtubs for your equipment. You can soak and wash equipment within the walls of berms such that the construction materials on your equipment does not sink into the ground or head for the nearest sewer system. Berms can also be used as catch-tubs for gray wastewater that is the direct result of rinsing out a cement truck and/or the chutes used to deliver wet concrete or wet cement to a specific site.
Most berms are semi-disposable. That is, you can use them more than once, and only change and dispose of the liners. You can also purchase completely disposable berms, which allow you to pick the whole gray water mess up, zip-tie it or wrap it, and dispose of it according to the EPA's rules.
Dissolving chemicals help break down the concrete, plaster, or cement such that it is neutralized and cannot harm anyone or anything. The chemicals themselves must be handled very carefully, but they are very effective at cleaning all of the liquid construction materials off of your equipment and the trucks. Be sure to only use the chemicals that the EPA has approved and marked with its seal of approval.
Recycling the Washwater and Materials
After you collect and/or dissolve the waste materials and washwater, you can recycle them. While it is unlikely that any DIYer would know how and where to do this, you can always consult a construction contractor to see how this is done. The contractor may even be willing to take the materials and washwater off your hands and recycle it for you. There may be a cost for this, but it is negotiable.
