APIS®
Soil Ion Exchange Additive
APIS® is an ionic-based chemical additive designed for the stabilisation and improvement of soils with low bearing capacity, particularly effective in fine-grained clay soils.
Originally developed in Germany in the 1960s and subsequently optimised by Strade Eco Soil-Tech, APIS® operates through cation exchange mechanisms, modifying the physico-chemical structure of soil particles. This process reduces plasticity, limits swell potential, and promotes granular matrix reorganisation, resulting in a significant increase in densification, cohesion, and mechanical strength.
Its application enables in situ soil improvement, minimising the need for excavation, transport, and material replacement, thereby reducing operational costs and environmental impact.
With proven performance across a range of geotechnical conditions, APIS® enhances key soil engineering parameters, including bearing capacity (CBR), compressive strength, and durability. It is an effective solution for road, rail, airport, and industrial infrastructure projects.
What is APIS?
"Chemical Innovation for Stronger Soils"
APIS is a water-soluble additive designed for the construction of new roads or the rehabilitation of unpaved roads. It acts chemically on clay particles in the soil, reducing their ability to retain water. This allows the soil to be compacted more densely, increasing its strength and durability.
Technical Benefits:
✅ Increases Load Bearing Ratio (CBR).
✅ Reduces the need for added materials.
✅ Minimizes the effects of moisture and erosion.
✅ Extends the life of treated layers.
Advanced Technology: Ionic Exchange
APIS® works within the soil matrix through cation exchange, fundamentally modifying its physico-chemical properties. The result is stronger, more stable soil with superior performance.
Versatile and Effective:
Ideal for large-scale projects and smaller works — roads, railways, airports, urban and industrial areas, ports, renewable energy infrastructure, and environmental projects. APIS® provides a solid, safe, and durable foundation.
Sustainability and Efficiency:
Reduces environmental impact by minimising resource use and preventing soil degradation. Its ionic action rapidly transforms high-cohesion soils into stable structures, saving materials, labour, and execution time.
Proven Durability:
A reliable technical solution delivering consistent performance and guaranteed return on investment for every project.
