Let's co-design sustainable and aesthetic spaces
With Colas, every project becomes a space for shared innovation: low-carbon materials, on-site testing, prototypes, and tailored support at every stage of the design. Our teams bring their technical and environmental expertise to create comfortable, safe spaces that are in harmony with their surroundings.
Materials & finishes: bringing substance to design
Every project begins with a texture, a shade, a material.
At Colas, technology serves architectural intent: natural aggregate colors, local finishes, permeability, and user comfort. Our Vegecol and Urbalith surfaces, aesthetic, high-performing, and low-carbon, adapt to various types of spaces: squares, pedestrian paths, forecourts, and heritage sites.
We support designers from the sketch stage to translate the architectural vision into a tangible, durable material that aligns with the identity of the place.
Low carbon & circularity: designing sustainably, building efficiently
Reducing the footprint without compromising performance. Colas designs and implements low-carbon solutions:
- Recycol, on-site recycling and lowered-temperature asphalt;
- Vegeroad, for durable pavements incorporating recycled materials;
- Recycled materials from our Nexstone and Valormat platforms.
This approach follows a circular economy and construction efficiency logic. Materials are selected based on their actual footprint (LCA), local origin, and potential for reuse. The goal: to create long-lasting surfaces while minimizing the overall environmental impact of the project.
Comfort & user safety: putting experience at the heart of the project
Comfort, safety, and clarity guide the design of public spaces. With the expertise of Aximum and Flowell, Colas integrates lighting guidance, signage, and visual contrasts from the earliest stages of surface design.
Our solutions ensure controlled slip resistance, optimal walking comfort, and enhanced accessibility for all users, including those with reduced mobility.
We work hand in hand with designers to combine functional safety with aesthetic continuity.
Landscaping: from design to execution
Colas designs and implements landscapes where technical performance and aesthetics go hand in hand.
Our teams ensure continuity between surfaces, vegetation, and usage, creating comfortable, vibrant, and resilient spaces. We integrate water management, permeability, and biodiversity considerations from the study phase, prioritizing local materials, permeable surfaces, and natural interfaces between mineral, plant, and street furniture.
Each project aims to enhance the living environment, reduce heat islands, and reconnect users with their surroundings.
Water & surfaces: integrating materials with hydraulics
A durable surface is also designed through its relationship with water. Our engineers combine draining foundations, vegetated swales, and connections (potable water, wastewater, stormwater) to promote infiltration and prevent runoff.
Permeable pavements thus become tools for climate adaptation, contributing to integrated stormwater management and the reduction of heat islands.
This systemic approach combines durability, user comfort, and landscape aesthetics.
Workshops & prototypes: from sketch to proof
Every project deserves to be tested. Colas offers material workshops to turn sketches into tangible prototypes: sample boards, test zones, and on-site trials. These experimentation phases allow validation of visual aspects, user comfort, and technical performance before implementation.
A true co-design space, where designers, engineers, and project owners collaborate to reduce uncertainties and ensure project success.
Designing a space means imagining a place to live.
At Colas, we believe a space can be functional, aesthetic, and meaningful at the same time. Working alongside architects, engineers, and landscapers, we turn design intentions into tangible outcomes—where material, technique, and use come together in a lasting harmony.
With our solutions, material workshops, and support at every stage of the project, we make co-design a true driver of innovation and urban quality of life.
Together, let’s shape spaces that inspire, protect, and endure.

Frequently asked questions
Public and private developments, squares, forecourts, pedestrian paths, transport hubs, urban promenades, or heritage sites. Each project receives tailored technical support from design to delivery.
Colas gets involved from the design phase to assist with specifications: material selection, feasibility studies, prototypes, and on-site support. The goal: to translate the project’s intent into a tangible and sustainable solution.
Yes. Our solutions and surfaces are compatible with the most demanding environmental certifications. Our teams can provide LCA data required for HQE or BREEAM assessments.
Our engineers and landscapers work together to integrate natural solutions: vegetated swales, permeable surfaces, de-impermeabilization, bio-based materials, and stormwater management systems.
