Dry and hydrophobic
Thanks to its exclusive manufacturing process, Laterlite Plus is dry and does not retain water. In construction and industrial applications, it is suitable for all typical situations where Laterlite Expanded Clay is used, particularly where humidity has to be minimal (in dry screeds, in proximity to moisture-sensitive materials, etc.).
An aggregate that is easy to mix with binders
Thanks to its hydrophobic characteristics, Laterlite Plus binds well with cement, hydraulic lime, and resins, and since it does not require pre-wetting it makes mortars and concretes easier to mix, improves their workability, and reduces drying time.
Effective against rising damp and with good drainage capacity
Thanks to the hydrophobic properties of Laterlite Plus, when is laid in contact with the ground (insulation of ground slabs, foundations and below grade insulation), it protects structures and finishes from capillary rising damp. It will not retain water and drains it away.
Load bearing insulation
Its porous internal structure makes Laterlite Plus lightweight (from approx. 320 kg/m3), thermally insulating (from lambda 0.09 W/mK), and sound-absorbent. The vitrified outer shell surrounding the granules makes them very hard with good resistance to compression and makes them ideal for load-bearing insulation and floor substrates, even very thick ones.
Extremely stable and durable
Laterlite Plus will not rot, cannot be attacked by parasites (fungus, rodents, insects, etc.), is resistant to acids, bases, solvents, and freeze-thaw cycles, is dimensionally stable and non-deformable, and retains its properties unaltered over time; for all practical purposes this material will last forever.
Mineral non-combustible and fire-resistant insulation
Laterlite Plus is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is fire-resistant and safe, including in the presence of fire. It is widely used in refractory applications.
A natural material that is ideal for sustainable construction
Thanks to its use of natural raw materials, its manufacturing process, which respects the environment, and the total absence of harmful emissions (even in the presence of fire), Laterlite Plus is ideal for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.
Laterlite Plus is manufactured and tested in accordance with international reference standards and is CE-marked to denote conformity to EN 13055-1, EN 14063-1, and EN 13055-2.
Laterlite Plus insulating aggregate is suitable for all the typical applications of expanded clay in, construction and industrial sector, where it has the added advantage of being dry and hydrophobic.
In construction they are especially indicated for the following uses:
Dry levelling compound for dry screed and granular fill for dry construction in general
Laterlite Plus 2/3 in granular form is used as a continuous lightweight levelling, compensating, and insulating granular fill and dry levelling compound. It does not require compaction and can be applied in thicknesses of 1 cm and above. When used as part of a dry screeding system it can be finished by laying specific types of panelling (SmartPly OSB, plasterboard, fibreboard, chipboard, etc..) to take the flooring.
- Levelling granules for dry screeds
- Dry levelling of sagging or deformed floors and decks
- Lightweight dry fill in new construction and refurbishment
- Nailed Wood flooring on joists or glued parquet on panels
Lightweight insulating backfill
Laterlite Plus Expanded Clay in granular form of 3/8 size can be used as insulating backfill between rafters and joists in timber suspended floors to improve thermal and acoustic performance whilst excluding humidity and not increasing the fire load. Its high strength enables it to support the weight of the finishing layers and it is also ideal as lightweight insulating backfill on top of vaulted structures.
Insulation and humidity control in contact with the ground
Laterlite Plus 8/20 in granular form is ideal for quickly creating backfilled underfloor voids to prevent rising damp. Its excellent stability and durability also enables it to be used at ground floors as a reliable hardcore layer below a ground slab or under foundations. It can also be used as insulation, drainage, or to reduce the thrust of basement retaining walls. The layer thickness can be controlled by using special TermoBag modular packs.
- Foundation slab insulation
- Ground slabs and below grade insulation
- Loadbearing insulation under floor screeds and concrete slabs
- Drainage of foundations and underground walls
- Compensated foundations
Applications when mixed with binders:
Laterlite Plus binds well with cement, hydraulic lime, and resins, and because it does not require pre-wetting it makes mortars and non-structural concretes easier to mix, improves their workability, and reduces drying time.
Mortars and lightweight concretes mixed with Laterlite Plus are suitable for the same uses as for Laterlite Expanded Clay.
The top surface of loose Laterlite Plus can also be consolidated with a cement slurry.
- Lightweight, insulating cement-based concrete for screeds and fillings – also for major works (embankments, etc…), floor screeds.
- Lightweight, insulating concrete based on Natural Hydraulic Lime (NHL) for screeds, fillings, slabs and screeds, cellar floors, etc..,
- Resin based mortars and concretes: use of Laterlite Plus as light mineral filler for resins.
Laterlite Plus expanded clay is an extremely versatile material that can be used both dry and loose on is own, or bonded with different types of binders, as required.
