1350 tons of earth excavation for a single-family house

If the soil is excavated and immediately loaded and disposed of, it will hardly have the opportunity to absorb water and then Max of 2to/m3 is to be assumed.

Present this calculation to the contractor and have them explain to you how this difference arises?

Have you, as the client, received the delivery notes of the disposal?

Yes, I have received the weighing tickets. The soil was wet due to days of rain.

I have now received 2 offers for backfill material. I need about 200 tons. 1. Construction rubble recycling material €8.33 / ton = €1666 2. Concrete recycling material €9.52 / ton = €1904 Which would you recommend?

Now I have also been offered Faulfels. I have never heard of it before. It is also supposed to be suitable for refilling. Can someone do that?

What does backfill sand cost?
