The right recipe: Why liquid soil always has to be planned individually

A building material with leeway — and responsibility

Liquid soil is more than just an alternative to traditional backfilling. It is a technical composition of soil material, water, binders and additives — tailored to the requirements of the project. The right mix determines load-bearing capacity, flow behavior, settling and degradability.

Since the soil conditions at every construction site are different and the subsequent properties must be precisely defined, there are no “standard recipes”.

Why standard solutions are not enough

No construction project is the same as the other. Whether it's inner-city sewer construction, traffic route construction or supply pipeline in the field — the requirements for liquid soil vary greatly:

• Does it have to be permanently stable or removable again later?
• Which densification is permitted or necessary?
• How quickly can the liquid soil set?
• What type of soil is being used?
• Are there any special requirements for environmental compatibility or groundwater protection?

An individually planned recipe takes exactly these parameters into account — for safe, efficient and rule-compliant construction.

Factors that influence liquid soil formulation

1. Condition of the initial soil

Sandy, clayey or loamy soil reacts differently to water and binding agents. The recipe must be tailored to the respective material.

2. Flow behavior and installation conditions

Narrow pipe trench in the city or extensive backfilling in the countryside? The desired flow behavior influences the choice of additives and water-binding agent ratios.

3. Sustainability and settlement behavior

Depending on the project, the liquid soil must be highly stable — or be able to yield in a targeted manner. This is influenced by binder content, additives and air pore control.

4. Tying time and construction schedule

On some construction sites, the liquid soil must solidify in a few hours, in others only after days. A tailor-made recipe prevents delays or downtimes.

5. Environmental regulations and recycling

Environmental suitability is crucial, particularly when it comes to Z.1.1 soils or close to groundwater. The use of recycled material also plays a role here.

How an individual recipe is created

With RMS Remake Soil GmbH The formulation is developed in close coordination with the customer and based on scientifically based processes:

1. analysis of the starting material (e.g. excavated ground)
2. Definition of technical requirements of the project
3. Laboratory tests to optimize the mixture (e.g. flow tests, test specimens, setting)
4. Preparation of a practical recipe Includes mixing instructions
5. Quality assurance through internal and external monitoring

The result: One customized solution, which is technically, economically and ecologically convincing.

Conclusion: An individual recipe is necessary

Liquid soil only develops its full potential if it is precisely tailored to the structural, geological and time requirements. An incorrect or inaccurate formulation, on the other hand, can lead to delays, rework or even damage.

Therefore, rely on well-founded planning right from the start — with a partner who Combining an understanding of the construction site and laboratory expertise.
