ᐅ Disposing of Excavated Soil Without Contaminant Testing / Soil Classification Documentation

Hello,

During a consultation today with a company specializing in solid construction houses, we were informed that we need to have our soil survey including a LAGA test (pollutant analysis) carried out.

If we then have to dispose of excess excavated soil at a landfill, they charge a fee per ton depending on the soil condition. If we cannot prove the soil condition through the pollutant analysis, the highest fee per ton will always be applied (as if we were disposing of contaminated excavated soil).

How was it in your case? Is this information correct?

The pollutant analysis would cost us an additional 400€ on top of the 4 soil boreholes.

Best regards and many thanks in advance for your feedback.

The statement is correct. It should also be noted that a landfill only accepts a certain amount (in our case 70 sqm (750 sq ft)) without a contamination analysis. Waste is only accepted if a corresponding investigation has been carried out.

Thanks for the answer! How big is the cost difference between disposal without a LAGA investigation and with a LAGA investigation? The note about the maximum amount accepted without a LAGA investigation is very helpful!

We can hardly estimate how much will actually need to be removed. The foundation slab will be about 9x9 meters (30x30 feet), and we will have a full basement with a height difference of 2 meters (6.5 feet) over the 30-meter (98 feet) plot length. We assumed that most of the material could be reused for refilling or building up to compensate for the slight slope.

Without proper storage, no one will take that amount from you... Because no one wants to accept, for example, 200 cubic meters of heavily contaminated material at their landfill...
And in your case, 9x9x2.3 meters (30x30x7.5 feet) already equals at least 190 cubic meters (6,710 cubic feet)...

That means it would actually make sense to ask the already commissioned soil expert to include the contamination test for an additional 400€.

Be careful! I don’t know if this applies everywhere, but here the report must not be older than 6 months! From the geotechnical survey to the final determination of the "remaining amount" after backfilling and shaping, the timeframe is very tight. We were offered €450 for the subsequent LAGA test, so it basically costs the same regardless of the timing.
