About Carmans

Carmans Aannemingen

Road construction

Drawing on more than 50 years of experience, Carmans delivers road construction projects for public and private clients alike – roads, sewers and car parks, always to strict quality standards. Class 6 accreditation and VCA** certified.

Soil stabilisation

Soil that has lost its bearing capacity does not always have to be hauled away. Carmans stabilises and improves it right on the building site, both vertically and horizontally: a cost-efficient alternative that also cuts down on soil transport.

Rubble recycling

Carmans pioneered construction rubble recycling. Concrete, brick rubble and asphalt are crushed and screened into high-grade aggregates, tested in our own lab and certified under CE, CERTIPRO and/or BENOR. For large volumes, Carmans brings mobile crushing and screening plants to your site.

Concrete plant

Carmans' computer-controlled concrete plant is among the most modern of its kind. It links the recycled raw materials to the finished product and is the place where BLUEBLOCKS are born.

Carmans Aannemingen delivers a broad range of infrastructure and earthworks for public authorities, industry and property developers. Thorough know-how and a modern fleet of machinery guarantee efficient execution, with close attention to safety, planning and quality.

Carmans Blue Technology

Soil remediation

At Carmans, contaminated soil is not a problem but a raw material in the making. Depending on the type and degree of contamination, we use one of three remediation techniques:

  1. Biological
    Biological processes break down oil contamination into harmless substances such as water and CO₂. Suitable for soil from petrol stations, oil depots and leaking heating oil tanks.
  2. Physico-chemical
    A sequence of techniques separates the soil into fractions. The heavily contaminated sludge is disposed of; the remaining fractions are reused as secondary building materials. Suitable for sandy to loamy soils contaminated with heavy oils, heavy metals, PAHs and chlorinated products. Various mineral waste streams, such as street sweepings, sewage sludge and car wash sludge, are recycled this way too.
  3. Thermal
    For heavily contaminated soils that cannot be treated biologically or physico-chemically, thermal remediation uses heat to break down the contamination. Suitable for heavy motor oil, PAHs and mercury.

Waste processing

Carmans processes a wide range of contaminated mineral waste streams: street sweepings, sewage sludge, gully sand, car wash sludge, filter sand and sand from oil-water separators. Waste that counts as a problem elsewhere is turned into reusable material here.
