With construction of a new home an excavation contractor will dig out the area for a foundation and drainage system. The operator in many cases will o all the back filling of the appropriate rock and soil around the foundation to ensure proper drainage.
For an existing home when the drainage fails the operators will bring in smaller equipment such as Bob cats and mini excavators into the tight spaces that require a fair amount of soil displacement. In some cases 20-30 tonne of soil and rock is not out of the ordinary. This might or might not seem like a lot but consider a full dump truck is usually around 15 tonne it might be more than you want to dig.
Then you want to get in a drain tile expert to re work your drain pipe system. As well as protect the concrete foundation with a protective wrap or a tar to waterproof the foundation.
In many cases a bin for the soil being removed is the best as they are low to the ground and easy to load.
