Regulatory management of excavated soil

Some construction and development projects require excavations and land transfers . However, any movement of land in Belgium is regulated in order to protect the environment and public health.

Before excavating and moving the soil to another location, you must analyze the quality of the soil. In Wallonia, this study corresponds to the Land Quality Report (RQT). It identifies the level of pollution and evaluates the quality of the excavated soil. The results obtained allow the identification of the procedures to follow for the management of the excavated soil and the most suitable outlets.

Our expertise in land management

Almadius, a multidisciplinary engineering firm, offers you its expertise in excavated soil management and soil quality. We take regulatory samples, draft the Soil Quality Report (SQR) and support you throughout the entire process, from initial analysis to soil recovery or treatment. Thanks to our practical, responsive approach that complies with environmental requirements, we help you manage your soil movements safely and with peace of mind.

Sample collection

The Almadius team is approved for taking soil samples as part of RQT, but we also take samples of groundwater, surface water, soil gas or ambient air.

Carrying out the RQT

As a soil expert, Almadius, via its certified subsidiary Hydreau, produces the Land Quality Report for any project that requires the excavation and movement of soil in Belgium. We take soil samples and analyze them.

This study identifies the contaminants present and their concentration in relation to regulatory thresholds. The outlet and the possible reevaluation of these soils according to their quality are determined on the basis of these analytical results.

Management of excavated soil

For polluted soils

The evacuation procedures to follow for excavated soil vary depending on the results obtained. In the event of soil pollution, the land must first be remediated so that it can be used elsewhere in the form of backfill or for another use.

In this case, they are sent to a processing center to be decontaminated while awaiting transfer to another site. We are responsible for monitoring these soils and providing management services to the soil treatment or soil collection centers.

For unpolluted soils

If the excavated soil has a pollution level below regulatory thresholds, it can be moved directly to an outlet. To do this, we assess whether the quality of the transferred soils is compatible with their future use on the receiving site.

We also help you with your registration as a receiving site.

The advantages of Almadius for the management of excavated soil

Pragmatic approach to excavated soil

Unlike a traditional design office, we go beyond producing the Land Quality Report. We continue our mission by providing practical solutions for the management of excavated soil after analyzing the results.

Multidisciplinary expertise

Our multidisciplinary engineering office is made up of experts specialized in different fields. This wide range of skills and services for several aspects of your site, linked to land management (stability, polluted soils, etc.) is an asset for your project. You benefit from a single contact for different areas of expertise, throughout your project.

Reactivity

In the event of an emergency for the management of excavated earth on your site, we are responsive and can respond to your request as quickly as possible . This responsiveness allows you to continue your work quickly.

FAQ: Management of excavated soil

Is the Land Quality Report mandatory?

K
L

In Wallonia, the Land Quality Report is obligatory in two cases: if the site of origin of the excavated soil is considered suspicious, that is to say in “peach” or “lavender” color on the Soil State Data Bank (BDES) or if more than 400 m 3 of land must be evacuated to another site.

At what stage of my work should I carry out the RQT?

K
L

We advise you to contact us before excavating the land on your site to carry out the RQT. You will thus have the guarantee that all regulatory requirements are respected from the start of the project and you will know in advance the possible outlets for your land. However, the soil can be analyzed as well after excavation, either in soil piles on the site, or after their transfer to an Authorized Facility (analysis by them).

What are the possibilities for unpolluted excavated soil?

K
L

If the excavated soil meets standards and does not exceed pollution thresholds for a given use, it can be reused in different forms: backfill, landscaping, site filling before construction, etc. We help to identify suitable sites to reuse this soil.

How do we manage excavated soil?

K
L

When the land is excavated, Almadius supervises its transfer to the treatment center and its sanitation or to other outlets depending on their level of pollution. After treatment of the pollution, this soil is moved to other sites for reuse.
