Technical Soil

The most economical solution for construction projects

As a geology company with decades of experience in countless small, medium and large construction projects in civil engineering, we do not believe that there is always just one right foundation solution. Rather, this is decided on the basis of economic aspects against the background of the respective individual construction project.

Our “Technical floors” are to be understood in this context. They offer a further alternative for identifying the most economical foundation solution in each case.

Definition

Technical soil is excavated soil that is modified by technical processes in such a way that it fulfills its function as an optimal construction material and can be reused within the construction site.
Additives (e.g. stabilizers, plasticizers) can be added to the soil for the technical modification of the soil for backfilling as an optimal construction material, provided that these are proven to be environmentally safe.

Fundamentals

It can be deduced from DIN 18300 that the surveyor must describe what he considers to be the most economical foundation solutions for the earthworks of the respective construction project. In addition to the exact description of the foundation solution, the delivery materials to be used must also be specified.

The “construction site” is understood as a system in which it is assumed that all natural and artificially introduced materials interact with each other (e.g. an introduced force always generates a counterforce). When determining the most economical solution, it is therefore not a question of comparing the cheapest products. Sustainable economic efficiency can only be determined by looking at the whole system.

An overall iterative process

In practice, the optimization of the foundation solution is an iterative process in which the statics and the formula are adjusted alternately. As the foundation solutions are developed individually for each construction site, the quality assurance of the technical floor must also be defined individually for each construction project during the planning stage. The final costs are calculated for this optimized foundation solution.
