Latermix Cem Classic is a lightweight, insulating no fines pervious concrete based on Laterlite expanded clay with an intermediate grain size, suitable for a wide range of applications, from sub screeds and fills for floor levelling including in high thickness, roof falls, up to drainage screed for the evacuation of rainwater.
Latermix Cem Classic is a bagged premixed lightweight concrete, ready to use after mixing with very little water, it dries quickly even in very thick layers. It is light, 600 kg/m3, i.e. less than a third of the weight of conventional or flowable screeds.
FIELDS OF USE
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.
Quick-drying concrete
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.
