How to guide – How to build a washout box

When a concrete pump is required to deliver concrete, a wash out box or area is needed. This is a necessity to help with the clean up process so that no damage is occurred to the surrounding area where the pump is placed on the site.

What is a wash out area?

A wash out area is an area of wasteland which is going to be renovated after the pour. For instance, if the pump is delivering to the back your property but is parked at the front on land which has not been finished, but has plans to be finished, this could be classed as wasteland as the washout will not damage or ruin the area.

What is a wash out box?

A washout box is needed when the pump cannot be situated on waste land and therefore a box needs to be assembled so that it can catch the wash out, thus, not destroying the area underneath. This should roughly be 2m by 2m and about a foot deep.

Materials needed for a simple wash out box

  • Wooden boards/ planks
  • Tarpaulin
  • Heavy objects such as bricks/rocks etc

Building the washout box

  • Step 1 – Put the wooden boards in a square and hold them together by placing the heavy objects to push the boards tight.
  • Step 2 – Put the tarpaulin inside and over the wooden boards to create the washout area. You will need to place this under the hopper of the pump truck.
  • Step 3 – After the pour, and when the washout has gone hard, you will need to dispose of this either via a skip or by taking to a local waste site.
