Welcome to Green City!
From houses to transport and energy infrastructure, select the city segment you want to discover and find out more on how you could use our sustainable materials and innovative solutions to build today the Green City of tomorrow.
Roads
Sustainable road-building is essential to building the circulatory system of the green city. Pedestrians, cyclists and roads should all enjoy equal access to safe, durable and eco-friendly pathways for work and pleasure. With infrastructure, there’s no such thing as “one size fits all.”
That’s especially true of roads, which vary widely depending on location, climate, vehicles, and cities. The nature of the soil can have a major influence on the overall road project. We are experts in soil stabilization and can offer solutions that suit any conditions. LafargeHolcim can help meet any challenge, anywhere.
To make road projects sustainable you can start with the assessment of the best solutions and materials to build roads in your area. Adding the power of digital, our ORIS platform for road design optimization helps reduce road project costs by up to one-third and carbon footprint by up to half while tripling road durability and lifespan.
The road pavement must be durable to ensure long lifespan and low maintenance of road surfaces - hence less CO2 emissions.
On the top of this, the use of recycled aggregates can strongly minimize the environmental impact of road projects. For example, aggneo is our range of high-quality aggregates processed from recycled concrete and thus help meet the challenges of construction and demolition within a circular economy.
Highways
Our integrated offer for road projects includes a complete range of products and services, best-in-class site supply management, and expertise in project management. We leverage a unique solutions portfolio that encompasses: soil stabilization, aggregates layers, concrete pavements, asphalt formulations, roller-compacted concrete, and fast-hardening concrete.
Traffic roads
Soil stabilization is an effective way to reduce CO2 emissions in road construction. Hydraulic binders like Doroport and Dorosol stabilize the ground and prepare it for the project. For a net zero road pavement, Green City used SuperLow, the industry’s first carbon neutral asphalt. It is manufactured at reduced temperatures and the remaining emissions are offset through climate projects. SuperLow can cool quicker, meaning less time for road repairs.
Urban areas
With mobility and climate change impacting the way cities are built, our specialized teams will help you from design to completion, suggesting solutions to help people better live in their cities. For example, the permeable Hydromedia concrete can rapidly absorb rainwater off streets, parking surfaces, and walkways - reducing the risk of flooding.
Rural roads
Roads are vital for communities all around the world and the choice of road materials is not simply about their construction, but about long-term benefits for end users. For example, Agrovial is an eco-friendly solution that enables agricultural soil stabilization by increasing resistance and durability, making rural roads stronger against traffic wear, tear, and rain.
Port
Ports are the critical interface between marine and land transport. Just as the airport is the hub for cargo with a high cost-to-volume ratio, so ports are critical for their opposite -- such as raw materials for heavy industry. This method of transport generally lowers the carbon footprint of goods conveyed compared to land or air.
Ports normally require large volumes of aggregates and concrete. ECOPact, our range of green concrete, is ideal for such projects. ECOPact is sold at a range of low-carbon levels, from 30% to 100% less carbon emissions compared to standard concrete. Where regulatory conditions allow, ECOPact products integrate upcycled construction and demolition materials, further closing the resource loop.
Breakwaters
With sea levels expected to rise further we offer solutions that protect vulnerable landscapes. In Holland we have developed a sea defense solution with Basalton precast blocks easy to install and maintain that make the barrier more resilient against sea waves.
ServicesPort
Quay
For coastal and flood protection, Green City has chosen Armourstone. This natural quarry stone is ideal for offshore subsea engineering projects thanks to its durability and resistance to wear and erosion. It is also available in many different pigmentations due to composition and petrographic makeup of the various quarry supply options. And we help place it with services such as loading at sea, board to board transfer and excavator equipped vessel supply.
Coast
Coastal management is more relevant than ever to preserve urban infrastructure and natural ecosystems. As sea levels are expected to rise further we offer solutions and materials that protect jetties and coastal and port infrastructure in vulnerable areas. We also partner with specialists to develop innovative concrete solutions for rehabilitating damaged ecosystems.
Bridge
Bridges compress the green city’s footprint, allowing residents to live and work on multiple levels at the same time, with overlapping layers and traffic corridors. Bridges are also typically the arteries for millions of visitors and commuters to dash into the city. They must be completely reliable under a range of climatic conditions over a lifespan of decades.
Bridges normally require large volumes of aggregates and concrete. What better source for bridge-building in Green City than ECOPact, our range of green concrete that is sold at a range of low CO2 levels, from 30% to 100% less carbon emissions compared to standard concrete. Where allowed, ECOPact integrates upcycled construction and demolition materials, further closing the resource loop.
Whether looking to build a new bridge or rehabilitate an existing one, with Ductal® UHPC you can build more with less. From joint fill to connect precast elements to bridge deck overlays to ensure durability, or for pier jacketing to guarantee longevity and seismic resistance, Ductal® is ready to take on your next major challenge.
Dam
When designed correctly, dams provide green, renewable energy to Green City. They are also critically important to Green City’s overall water management strategy, storing water in times of excess water flow and releasing it when natural flows are inadequate to meet water demand.
Through our experts in energy projects, we provide public bodies, investors, contractors, and engineering firms with a global offer and specific solutions for hydropower dams, such as our Ultra High Performance Concrete (UHPC) and ultrafine cements for repairs.
Main structure
Dams require large volumes of aggregates and concrete, particularly for the main structure. ECOPact green concretes are ideal for such projects. ECOPact is sold at a range of low-carbon levels, from 30% to 100% less carbon emissions compared to standard concrete. Where regulatory conditions allow, ECOPact products integrate upcycled construction and demolition materials, further closing the resource loop.

Water tunnels
When it’s about protecting a structure from water ingress or retaining water within a structure, Watertight ready-mix concrete is our choice to build the dam of Green City. Ideal for external membranes or cavity drainage, Watertight prevents water from flowing and eliminates the need for complicated jointing - reducing both costs and time. And this unique product comes with a multi-year warranty to boost confidence in our customers.
Airport
Well-designed, well-managed airports are key to the vitality and economy of the green city. They are the emblem of openness to the global economy, channeling high-value, low-weight, time-sensitive cargo, which includes everything from tourists to semiconductors.
Airports are normally symbols of the green city’s arrival on the world stage and aesthetics are no small consideration. Ductal UHPC, offers unmatched qualities of durability, strength, aesthetics and ductility, while Artevia decorative concrete gives free rein to bold aesthetic and architectural projects. Both are also long-lasting, ensuring the airport’s long lifespan.
ServicesAirport
Airside
Extensia concrete extends industrial floors, helping to put buildings into service quicker and better resist wear and impact of heavy vehicle traffic and high mechanical loads. Combined with steel reinforcement, it allows to reduce the volume of concrete and the energy consumption during pours, being a more sustainable choice for airside floors.
Expansion projects
Growth means more efficient and larger airports but upgrade and expansion projects are typically costly and lengthy. Not in Green City. Here we use Chronolia high early strength concrete to gain time (3-5 times faster than standard concrete), reduce cost and avoid close contact between workers on site. It’s perfect for projects on a tight schedule or which have experienced disruptions, and to improve quality in key airport surfaces such as the apron.
Passenger terminal
While ductility and aesthetics are obvious characteristics of Ductal UHPC, this concrete also enables to build more with less, to build light structures, and offer a sunshade effect on a building’s facade. This helps to naturally reduce the temperature inside the building and consequently use less energy to keep the airport cool.
Foundation
Housing
Sustainable urban living is a combination of many factors, beginning with the homes we live in and the materials we use to build them. We need to apply low-carbon and circular solutions wherever possible, lower the carbon and energy intensity of our homes over their lifecycle, and look to recycling the construction and demolition waste when they finally are replaced.
Susteno cement, the first and only resource-saving cement in Europe that uses fine mixed granulate from demolished buildings as an additive, is the perfect foundation for building green and circular housing in Green City.
To insulate those homes, Airium mineral foam has a lower CO2 footprint over its lifecycle than traditional insulating products, on top of offering better air quality and higher energy savings.
Services
Insulation helps keep interiors cool, thus reducing energy consumption from air conditioning and other cooling technology. Airium's special quality is that it can be used to insulate and build at the same time, saving both time and materials. This mineral insulating foam is fully fire-resistant and long-lasting, with the capacity to fill any type of shape and cavity - ideal for both building and renovation.

LandscapingDriveways
Walls
Walls can be built in different ways, and we have sustainable solutions for each of them. With Airium bricks you can build and insulate at the same time. With the dry mortar 3D printing solution Tector you will optimize the materials used and minimize the risk of construction errors. Finally, special masonry cements such as Maestro or Forte reduce the carbon footprint and the amount of materials needed per m2, while offering faster and better workability.
Roof
Integrating rainwater management into construction is a must in Green City. Thanks to the combination of Hydromedia permeable concrete and Siplast Waterproof System, ROOFTOP duo TM offers an efficient water management system which is applicable to walking and parking areas too. And for roof renovation, you could use Airium which insulates and builds at the same time.
Floor
We offer different sustainable solutions for smooth and finished floors. Self-levelling and self-placing Agilia concretes and screeds naturally flow and spread effortlessly, reducing worksites noise, manual placement and vibrations. Thermedia improves insulation and energy performance, reducing heat loss by up to 35% and helping achieve the most advanced international environmental certifications.
Facade
Buildings in harmony with their environment naturally optimize the use of energy for insulation, heating and cooling. Ductal elements can create shade, protect insulation materials, collect rainwater, optimize wind conditions, and look beautiful! And when weather conditions make houses subject to damage from rain and moisture, you can protect them with water resistant cements like Kawach, Hydro or Unikal.
Tunnels
What makes Green City different from its predecessors? Among other things, it is quieter, less congested, the air quality is higher and it is safer for walking and cycling. All of these factors are enhanced by building tunnels.
Enabling easy and efficient transportation through complex geographical areas is no secret to us. LafargeHolcim has unmatched know-how to make your tunnel project for metro, rail, and roads across the globe a success.
We partner with you to deliver tailor-made solutions to meet your needs from site preparation to the development of special products and solutions such as resistant and long-lasting cement, ultra-fine binders to reduce soil permeability, specific concrete mix designs.
Recycling
The excavated materials may also be converted into recycled aggregates, contributing to future building projects as aggneo recycled aggregates.
Cement
Tunnels require large volumes of cement, so it makes sense to use Susteno, the first and only resource-saving cement in Europe that uses fine mixed granulate from demolished buildings as an additive. For rapid regeneration, we suggest using Ductal® Shotcrete, which reduces the amount of materials required.
Services
Digital tools like ORIS and COPave help build sustainable tunnels by suggesting low-carbon products. Our mobile app ConcreteDirect helps customers manage orders and track deliveries of concrete reducing trips, complexity and workload at the jobsite as they can always know where the order is and when it arrives.
Lining segments
Our sprayed Ductal® Shotcrete is the only one on the market that can be applied directly to vertical walls or vaults by spraying it. It ensures rapid and durable regeneration and reinforcement of culverts, dams, bridges reducing the amount of building materials needed to ensure similar levels of renovation.

Railways
Metropolitan lines make stringent demands on accessibility, aesthetics and public acceptance. Our decorative concretes Artevia give free rein to your boldest architectural projects. It’s quick to use, easy to maintain, resistant to wear and fits even the most complex shapes. Concrete can be decorative at night too: Light-absorbing by day, phosphorescent at night, Artevia Boreal lights up the night without consuming energy.
Railway stations and railbeds require high volumes of aggregates -- for which our aggneo offer is perfect. aggneo is a range of high quality aggregates processed from recycled concrete that can be combined with services and solutions to help develop the rail network of Green City. Using aggneo ensures that resources are not unnecessarily depleted and reduces the impact on landfill sites.
Tramway
We know that metropolitan trains and tram lines often make stringent demands on construction companies and transport operators, such as infrastructure availability, aesthetics and public acceptance. Our decorative concretes Artevia give free rein to your boldest architectural projects. It’s quick to use, easy to maintain, resistant to wear and fits even the most complex shapes - ideal to build tramways.

Piers
As the construction of piers requires large amounts of aggregates, sustainably-sourced aggregates can drastically reduce the environmental footprint of the project. aggneo is a range of both high quality aggregates processed from recycled concrete and services that help build within a circular economy - from waste management, logistics and traceability, to quality control, treatment and recycling.
Beams
Deck
Ductal structural overlay forms a thin, watertight layer that can withstand freeze and thaw cycles while resisting chloride penetration from de-icing salts. This allows traffic to flow just a few hours after casting and to quickly restore the load-bearing capacity of bridges, without requiring additional work on piers and foundations.
