Soil improvement


Soil improvement can be used to immediately optimise the installability and compactibility of soils and building materials. The procedure is used in particular to facilitate the execution of construction work on land and traffic areas.

When improving the soil with lime products from Fels, the following processes are in the foreground:

  1. Ground drainage
  2. Aggregation of cohesive soil particles
  3. Ion exchange
  4. Pozzolanic reaction

This significantly improves soil mechanics and also has a positive effect on structural properties such as plasticity, compressive strength, shear strength and tensile strength.

Unsuitable fine-grained (cohesive) or mixed-grained soils can be processed immediately by lime products from Fels and brought into a condition that ensures that the construction work runs smoothly and on schedule.
Both over-wet, non-compactable and dry, compactable soils are altered in their properties by treatment with lime in such a way that a high utility value is maintained in the operating condition in the long term, even under extreme traffic conditions and weather conditions and in the presence of water.


Hardening with lime products leads to long-term reactions in the form of:

  1. Long-term increase in strength
  2. Durable load-bearing strength
  3. Rapid dehydration
  4. Space stability
