Disposal of excavation material without pollutant testing/proof, soil class

But watch out! I don't know if that applies everywhere, but with us the report must be max. 6 months old! From the soil investigation to the final determination of the "residual quantity" after backfilling and modeling, that becomes very tight. We were offered €450 for the subsequent LAGA test, so it costs practically the same regardless of the time.

Oh, good to know. We will take care of finding out how the landfill handles this right away on Monday. We only have one construction waste landfill in the immediate vicinity and I think that will be the only one that will be used.

Right, I completely forgot, with us it's only valid for 6 months as well...

Hello,
so if you have the possibility to temporarily store the earth masses, then do the analysis according to PN98 only when you have everything together that you want to dispose of. One composite sample per 500m³ is sufficient for the landfill. However, make sure that you have the classification done according to LAGA and DepV. LAGA is the recyclability and DepV classifies the material into landfill classes that are relevant for landfills.

Additional costs are actually only the extra trip, but in return you have the security that you have disposed of or removed everything and have a current analysis.

The disposal of earth masses is increasingly becoming a problem and should not be neglected. Nowadays good earth masses are treated like hazardous waste.

By now, good soil masses are treated like hazardous waste.

Yes, unfortunately. It makes it easier for the operator to print money.

We partly gave away our soil masses on eBay Classifieds.
Posted weeks in advance and then arranged delivery while the excavation pit was being dug.
Just as you have to haul them away, others have to bring in larger quantities - and they also want to do it with as little financial effort as possible.
With a bit of patience and effort, a few win/win situations can arise.

However, you will most likely not get around sampling.

You need an expert opinion anyway.

Then eBay Classifieds, some stuff always gets sold, filling the slope of the excavation pit, terrain modeling, etc.

In the end, ask building material suppliers (aka: gravel pits), they often accept and recycle. Alternatively, check out the "janitorial services" "all-round handymen". We found one here who has a screening plant and a crusher in the forest, makes such fill soil and RC himself and then installs it at the building suppliers’ sales price for his customers…

The base slab will be about 9x9 meters and we are fully basementing with a height difference of 2 meters over a 30-meter plot length.

And for you, 9x9x2.3 is already at least 190 cubic meters...

That will be significantly more, about 3 meters deep (2.2 basement, 30 base slab, 50 cm clean layer on about 11x11 m sloped away is 360 m3 volume, or about 500 m3 loosened soil. Minus what is eliminated due to the hillside location. Can all of this really be used for refilling or piling up?
