Floor screeding with lightweight concretes and mortars consist in laying on top of a loadbearing support, such as a slab or a deck, a screeding mix based on lightweight aggregates, or a sequence of screeding mix layers, to obtain a defined level and a suitable subfloor surface while minimising the dead loads.

Laterlite floor screeding mixes based on Expanded Clay Lightweight Aggregate, reduce dead loads by up to 75% as opposed to conventional screeds, thanks to the low density of their main LWA component, that also significantly enhance the screed thermal and acoustic performance and is non-combustible.

At the same time, they have high compressive strength and stability and are therefore suitable for the same uses of normal weight aggregates screeds, both Indoor and outdoor, Including roof screeds.

Screeding with Laterlite lightweight concrete and mortars Is especially useful:

  • when the supporting slab has a limited loadbearing capacity
  • when the screed depth to be applied to reach the defined floor level is high
  • when renovating a building to reduce loads on structures and foundation
  • In new buildings, especially light wood and steel frame structures and high rise, to reduce the size and the cost of vertical structures

LIGHTWEIGHT SCREEDS (TOP SCREED)

The Laterlite range of CE marked bagged premixed lightweight screeds can be used for high performance floating, bonded, and unbonded screeds without overloading existing floor slabs.

Latermix Forte, Facile and Fast bagged lightweight screeds have a semi-dry “damp soil” consistency, are laid using traditional screeds application technique, to meet every requirement of the construction site. They are quick drying (Latermix Fast), can extend over large surface areas without requiring joints (Latermix Forte), and are suitable for external use (Latermix Fast and Latermix Facile).

They all have a very smooth surface finish that is suitable to take any type of flooring (ceramic, stone, wood, carpet, vinyl) and can be manually or mechanically smoothed (screed smmothing machine. power trowel). They also reduce the dead load on structures by half as compared to alternative traditional or self-levelling screeds (they weigh approximately 1000 kg/m3 laid and dried).

Latermix Cem Mini is semi-fluid and is the most versatile and lightweight of these screeds (weighing only 600 kg/m3) and gives the greatest load reduction.

All Laterlite screeds can be mixed by traditional means (in a cement mixer) or mixed and pumped in a pneumatic floor-screed conveyor machinery for easy transport to the required floor.
