Buildings.
Lighten. Insulate. Renovate.

The low weight and thermal insulation of BLC lightweight concrete open up possibilities for floors, fills and precast components. Explore applications with your design team.

Lightweight fill in a floor assembly to be designed.

Conceptual floor diagram: load-bearing substrate, lightweight BLC fill and finishing system.
Illustrative diagram, not to scale. It is neither a construction detail nor a validated assembly; interfaces and additional layers must be defined.
  1. Existing or new load-bearing substrate, verified by the designer.
  2. Non-structural lightweight BLC fill: formulation and thickness to be defined.
  3. Finishing system and interfaces selected for the intended use.

Four application areas.

01

Lightweight screeds and levelling fills

Levelling, covering services and filling beneath floor finishes: consider a lightweight solution based on the substrate, available thickness and intended finish.

02

Renovation and rehabilitation

Consider lighter fills for existing floors where added weight matters. The designer checks allowable loads and the complete assembly.

03

Non-structural insulating fills

Fill volumes and incorporate a thermal function in an assembly designed for that purpose, with suitable interfaces and moisture management.

04

Precast components

Insulating cores, non-loadbearing moulded elements and custom modules: develop components with manufacturers, from design through qualification.

Explore precasting

Three reasons to consider BLC.

01

Reduce added weight

Compare the weight of the complete solution when exploring renovation, fill or precast applications.

02

Integrate thermal insulation

Use the material’s documented low thermal conductivity in an assembly that accounts for thickness, moisture and thermal bridges.

03

Plan placement

Coordinate pumping, levels, openings and curing with the installer, taking site access and construction constraints into account.

From housing to shared buildings.

Residential and multi-unit housing, retail, hotels and institutional buildings: start with the needs of the project — reducing fill weight, levelling a surface or integrating insulation.

Available evidence and required qualification.

TopicAvailable dataBuilding application validation
Density and strengthTest results for the historical formulation; methods and conditions in the technical dossier.Verify the proposed formulation, loads, substrate and role of each layer.
Thermal insulationThermal conductivity measured on dry material.Assess thickness, moisture, interfaces and thermal bridges in the assembly.
Fire, acoustics and interfacesThis dossier does not establish qualification of a building system.Define applicable tests and requirements: fire, acoustics, adhesion, drying and finish compatibility.

MTQ status applies only to the evaluated pavement insulation formulation and use. A building application requires separate qualification.

Review the evidence

Plan your application.

  1. Describe the need

    Specify the building type, substrate, areas, thicknesses, finishes and schedule.

  2. Assess the assembly

    Your design team defines loads and applicable thermal, acoustic and fire safety requirements.

  3. Prepare construction

    BLC, the producer and the installer define the formulation, necessary tests, supply arrangements and site quality checks.
