QUICK-DRYING LIGHTWEIGHT INSULATING PERMEABLE CONCRETE. FOR USE (INCLUDING IN THICK SCREEDS) AS A BASE OR BACKFILL, A SUBSTRATE, FOR CREATING FALLS AND FOR INSULATION AND DRAINAGE
Latermix Cem Classic is a bagged pre-mixed lightweight permeable insulating no fines concrete based on special Laterlite Plus hydrophobic expanded clay of intermediate grain size, and is ready for use after mixing with only water.
Quick-drying: The mix requires only minimal amounts of water and dries quickly even in thick layers, thanks to its open-pore structure and its formulation based on hydrophobic Laterlite Plus expanded clay.
Lightweight: 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.
Insulating characteristics: Because is over than 10 times more insulating than traditional concrete products (? =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: It 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: Thanks to its network of intergranular voids it 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.
N.B. if an impermeable layer or top finish is to be applied, a levelling screed is required.
