The open structure of Latermix Cem Classic, combined with the hydrophobic properties of Laterlite Plus Expanded Clay, allows the product to be mixed with minimal amounts of water, thus achieving rapid drying even for thick layers. Latermix Cem Classic can be covered with subsequent layers after 1 day.
Latermix Cem Classic thus provides a minimum amount of water to the building and is particularly suitable for existing structures or finishes that are sensitive to moisture.
Latermix Cem Classic, in situ, weighs approx. 600 Kg/m3, less than one third the weight of a traditional or flowing screed and less than a quarter of that of structural concrete. It reduces dead loading and is particularly suitable for reconstructing existing floors, vaults, or roofs, or to prevent excessive loading in seismic zones.
Because is over than 10 times more insulating than traditional concrete products (thermal conductivity lambda λ =0.134 W/mK), it can be used to supplement or replace the insulation in flat or pitched roofs, floor slabs, and vaults, and reduces thermal bridging. Its porosity improves acoustic insulation.
Strong, stable, and durable
Latermix Cem Classic has high compressive strength (2,5 MPa), is dimensionally stable and non-deformable, and retains its properties unaltered over time. It is the ideal support to take top screed layers.
Non-combustible and fire-resistant
This is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is fire-resistant and safe, including in the presence of fire.
High drainage capacity concrete
Thanks to its network of intergranular voids Latermix Cem Classic is extremely permeable to water and can also be used as support, backfill, or as a layer of draining ballast on a roof or on the ground.
Suitable for sustainable construction
The natural raw materials used in Latermix Cem Classic, its manufacturing process, which respects the environment, and the absence of harmful emissions (even in the presence of fire), make it suitable for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.
- For creating falls and thermally insulating flat roofs.
- As a lightweight insulating substrate on a floor slab (incorporating services if required)
- As a lightweight insulating backfill and levelling including in thick layers (vaults, etc.)
- As a lightweight draining layer of good compressive strength.
N.B. if an impermeable layer or top finish is to be applied, a levelling screed is required.
