Sustainable solutions

A particularly sustainable method that does not require the use of cement is the vibration tamping method. By using natural and locally available materials such as gravel and crushed stone, this subsoil improvement method is particularly environmentally friendly.

In the soil mixing process, the native soil is mixed with a binder suspension. This significantly improves the mechanical and physical properties of the soil. The overlapping columns create a continuous soil mixing wall that can be used for cut-off walls or excavation pit stabilisation.

In addition to the horizontal sealing function, the soil mixing wall can also perform static functions.

To prevent pollutants from contaminated soils entering the groundwater, we can secure them using jet grouting with overlapping DSV columns. DSV sealing blocks bind the pollutants and thus protect the groundwater in the long term. The stabilised soil can later be extracted, fed into soil treatment plants or disposed of professionally.

Sealing slabs are used to seal the surface of excavation floors against vertically rising groundwater. The soft gel injection base is a particularly environmentally-friendly process that we manufacture economically, safely and with an excellent CO2 footprint. Our environmentally neutral bio-soft gel is one of three soft gels with general type approval from the German Institute for Building Technology (DIBt).

Recycled building elements pay off for you. Instead of extracting soil, the soil mixing method uses the existing soil. Using a leader-guided mixing paddle, we mix the soil with a comparatively small amount of cement suspension to create an earth concrete body. To realise shoring walls with low deformations, load-bearing elements are placed in the fresh earth concrete body.

If you need a pile foundation anyway, the additional costs for near-surface geothermal energy are low. We will be happy to consult you on the planning of energy piles. This allows you to heat in winter and cool in summer.

Shallow geothermal energy in combination with modern heat pumps offers a cost-effective, low-maintenance and virtually emission-free energy supply, in addition to the use of locally available resources such as heat and cooling. Besides being permanently available, it can be realised at almost any location.

With deep drilling of up to 400 m, the existing natural geothermal potential on your property is used particularly efficiently. In this way, we are making an active contribution to the decarbonisation of energy supply.

With our slender Displacement piles - Greenpile - such as the Frankipile NG® or the atlas pile, we save a considerable amount of concrete compared to alternative pile systems. The efficient use of materials conserves resources. In addition, the soil displacement means that no drilling material is produced. This means that no additional transport or external utilisation is required. Conclusion: You save costs, reduce emissions and relieve the burden on neighbouring construction sites. All of this also increases your project's eligibility for approval.

We replace contaminated soil with uncontaminated soil using overlapped, cased large boreholes. The drill heads for the replacement boreholes have a diameter of up to 2 metres. The excavated material is then fed into soil treatment plants.
