Meet the Experts Behind Smarter Ground Solutions
Welcome to Build Dialogues, Leca International’s webinar series where leading engineers, researchers, and industry specialists meet to share knowledge, discuss real projects, and explore the future of sustainable ground and foundation design.
From major infrastructure developments to cutting-edge research, each session offers valuable insights into how Leca® Lightweight Expanded Clay Aggregate is being used to solve complex geotechnical challenges around the world.
In our live conversations, you’ll meet highly experienced professionals, from geotechnical gurus with decades of expertise to project teams behind full-scale testing in high-speed railway environments. Together, we dive into performance, durability, design choices, and practical implications for roads, railways, climate adaptation, and more.
Expect engaging discussions, solid technical arguments, and plenty of opportunity to ask questions, both in advance and during the session.
Whether you work in geotechnics, foundation engineering, or infrastructure planning, Build Dialogues is your platform to learn directly from the experts shaping tomorrow’s construction solutions.
Our BUILD Dialogues
Heavy Arguments - Light Choices
Meet Arnstein Watn – a geotechnical guru!
With more than 40 years of experience in consulting, research and project management – nationally and internationally – Arnstein has played a key role in developing solutions for roads, railways, quays, airports and climate adaptation. He has led and contributed to several major construction and R&D projects and is a highly sought-after expert. Join the webinar and gain insights from one of Norway’s most experienced geotechnical engineers.
In this webinar, you’ll meet Arnstein in a live conversation with Leca Sweden’s geotechnical engineer, William. Together, they’ll discuss your questions, share experience, insights – and plenty of solid arguments for making smart choices in ground and foundation design.
If you work in geotechnics or foundation engineering – you don’t want to miss this.
Performance Under Pressure
Meet the experts at the CEDEX Track Box.
In this webinar, you will gain detailed insight into the PEDLER project (Performance and Durability of a Leca lightweight expanded clay filling in Railway embankments). The main objective of the project is to understand the behavior of expanded clay (Leca® LWA) used as embankment material in high-speed railway infrastructure.
The session presents the results of full-scale (1:1) tests carried out at the CEDEX Track Box (Madrid, Spain), focusing on performance, durability, and material behavior under conditions representative of high-speed rail traffic (up to 400 km/h).
We will present results under static and dynamic conditions, simulating train arrival, passage, and departure at different speeds. Fatigue test results after the passage of one million railway convoys will also be shown. Most importantly, the session will include a comparison with conventional railway embankments, addressing a key question: do Leca embankments have any limitations in use, or not?
You will meet the project experts in a session hosted by LECA International, where research outcomes, testing methodology, and practical implications for railway embankment design will be discussed, with time allocated for questions and discussion.
Your hosts for this session:
- José Estaire - PhD in Civil Engineering, Head of Department at the Centro de Estudios y Experimentación de Obras Públicas, Head of the CEDEX Track Box
- Raúl Murciego Zaballos - Head of Consulting & Sales Strategy. Infrastructure Projects, Leca Spain.
