EPS backfill: lightness and performance for your projects
Discover our lightweight, high-performance and durable EPS backfill solutions for all your insulation and landscaping projects.

The advantages of EPS for backfill
Compressive strength
EPS limits load stresses, protecting underground structures.
Lightweight and easy to install
Its low density simplifies cutting, handling and on-site installation.
Economical and ecological solution
EPS reduces the use of topsoil and optimizes site logistics.
Reduced truck rotations
EPS reduces the number of rotations and the grey energy required for construction.
The advantages of EPS for lightweight backfill
Expanded polystyrene's strength and durability make it a must-have for lightweight backfill. Used in civil engineering and landscaping, it meets the technical challenges of outdoor structures. This material is ideal for insulating retaining walls, buried structures and bridge approaches. With its unique properties, EPS guarantees efficient load management while respecting environmental constraints.
Drainage and stormwater management
Expanded polystyrene is ideal for urban drainage thanks to its lightness, stability and compactness. Used in drainage panels, it facilitates rainwater management in urban projects. Our Drainbox 60 sheet solutions help preserve plants by preventing asphyxiation and frost. Suitable for green roofs, green spaces and permeable parking lots, they enable efficient water management.
EPS solutions: reduced ecological impact
Using EPS for backfill and drainage reduces the environmental impact of the entire process, from manufacture to installation. Recyclable and easy to install, EPS is a sustainable alternative to traditional materials. It also reduces nuisance on building sites by requiring less transport and labor. Finally, it complies with environmental regulations, promoting greener construction.
