Every day, people around the world live, work and play on ground prepared by Keller, the world's largest geotechnical specialist contractor. Used alone or in combination, our techniques solve a wide range of challenges across the entire construction sector – from industrial, commercial and housing projects to infrastructure construction for dams, tunnels, transportation and water treatment, as well as projects to address environmental challenges. Global strength and local focus are what makes us unique. Our knowledge of local markets and ground conditions means we’re ideally placed to understand and respond to a particular local engineering challenge. Our global knowledge base then allows us to tap into a wealth of experience, and the brightest minds in the industry, to find the optimum solution. With around 10,000 employees and operations across five continents, we have the people, expertise, experience and financial stability to respond quickly, get the job done and see it through safely. By connecting global resources and local knowledge, we can tackle some of the largest and most demanding projects around the world but the everyday work we do is just as important and, in total, we tackle an unrivalled 6,000 projects every year.

Un nouveau chantier achevé sur l'agence Sud de KELLER Fondations Spéciales : Réalisation d'une paroi définitive en pieux sécants autostable dans le cadre la construction d'un nouveau Centre de Tri sur la commune de MONTE (à côté de BASTIA). Merci à notre partenariat renouvelé avec la société #NATALI et plus particulièrement Yann Coulombeau MOA : #SYVADEC #KellerExcellence
Thank you to those following along in our #sustainabilityseries leading up to Keller’s Sustainability Week! Today, Luke Deamer highlights what climate change means for our equipment as we decarbonize across different markets at different rates. #KellerExcellence #SDG13 #ClimateAction
🌍 Keller s’engage pour le climat ! 🌱 En 2024, nous avons lancé notre bilan carbone en partenariat avec Global Climate Initiatives afin de mieux comprendre et réduire notre empreinte carbone. Cette initiative s'inscrit dans notre volonté de : ✔️ Évaluer précisément nos émissions de CO₂ ✔️ Nous former au bilan GES ✔️ Suivre notre impact environnemental ✔️ Répondre aux exigences du Groupe Keller en matière de neutralité carbone ✔️ Satisfaire les attentes de nos clients ✔️ Contribuer au plan neutralité carbone du gouvernement français 📊 Des actions concrètes pour un avenir plus durable Suite à notre bilan, nous avons mis en place quatre groupes de travail axés sur nos principales sources d’émissions : 🔹 Matériaux et services entrants 🔹 Énergies 🔹 Déplacements 🔹 Actifs et gestion des déchets Ces équipes ont défini des actions concrètes qui seront progressivement déployées afin de réduire notre empreinte carbone et avancer vers un futur plus responsable. 💡 Chez Keller, nous sommes convaincus que chaque action compte. Ensemble, faisons bouger les lignes pour un secteur plus durable ! 🙏 Un grand merci à Global Climate Initiatives pour son accompagnement dans cette démarche essentielle ! #kellerexcellence
Eid Mubarak from us all at Keller! Wishing you and your loved ones a joyful and peaceful Eid. May this season bring happiness, unity and prosperity to all. #wearekeller #eidalfitr

A dear topic for me once again. My friend Solve Hov and his colleagues at NGI - Norwegian Geotechnical Institute and KELLER have conducted a field study related to wet deep mixing. Solve Hov, Henrik Meland, Anıl Helvacıoğlu, Robert Thurner, and Åse Marit Wist Amdal. Distributed Fiber-Optic Strain Sensing in Deep Mixed Columns. J Geot Geoenv Eng, 2025, 151(2), 05024015. https://lnkd.in/dqAp3i2q I’m really excited to share this cool study they conducted in Trondheim, Norway. They integrated fiber-optic cables into wet deep mixing columns, the very first time anyone in the Nordic region has used Distributed Fiber-Optic Sensing (DFOS) technology. DFOS was used to measure temperature, strain, and vibrations, and it worked alongside the usual geotechnical tools like pore pressure and settlement measurements. The main goal was to capture how the columns deformed under load, and the sensors delivered an impressive resolution of 2–3 cm. With the columns loaded with up to 5.5 m of soil, the sensors clearly picked up the applied loads. What’s interesting is that the data showed significant variations in deformation along the length of the columns, highlighting a non-uniform behaviour, maybe expected since this type of soil-binder material has high property variability. Plus, the study confirmed that the sensors stayed firmly in place under heavy loads and that their readings were in line with conventional deformation calculations. This study featuring the advanced technique is highly sought after. Previously, measuring deformations at such high resolution was nearly impossible, especially inside the column. Now, this technology enables us to analyse load transfer and distribution between the soil and columns more effectively. Managing load distribution along the entire column proves challenging in design, especially when installing floating columns or columns of different lengths. A deeper understanding will definitely lead to more cost-effective designs by the possibility to optimize the area ratio (based on column diameter and cc-distance), particularly in regions with low embankments or floating columns. I really look forward to reading further studies on this topic. //S #KTHSoilAndRock
Congratulations Lőrinczi Tünde 💐💐💐
Area Manager at Keller and President of the Swedish Rock Engineering Association | Co-chair for the World Tunnel Congress, WTC 2025
🏗️✨ Vi på KELLER Grundläggning är stolta – men inte förvånade – över att vår kollega Tünde är en av de 51 förebilder som valts ut i processen för att bli Årets Byggkvinna 2025 av Byggföretagen! Av 113 nominerade har Tünde gått vidare som en av kandidaterna som inspirerar, visar vägen och gör skillnad i en bransch där vi behöver fler kvinnliga ledare. Tünde är inte bara en tekniskt skicklig geotekniker med erfarenhet från flera länder i Europa – hon är också en ledare i en operativ roll, mitt i produktionen, med ansvar för personal, ekonomi, projektledning och tekniska lösningar. Hon leder – och levererar – varje dag. Med sitt tekniska kunnande, sin erfarenhet och sin starka position i produktionen är Tünde en förebild i byggbranschen. Hon visar att jämställdhet inte handlar om var du kommer ifrån, utan om kompetens, beslutsamhet och att våga ta plats. Grattis Tünde – vi hejar på dig hela vägen till finalen! 🙌 (De tre finalisterna presenteras 8 maj och sen röstar juryn fram vinnaren, som avslöjas vid ett digitalt event 16 maj.) #åretsbyggkvinna #byggbranschen #ledarskap #geoteknik #grundläggning
