SMARTBLOCK® lightweight concrete blocks with EPSLight to lay.Heavy on performance.
Solid blocks from 300 to 1200 kg/m³ that insulate throughout their mass, are non-combustible (A2-s1,d0) and lay with interlocking joints. One material for infill walls, partitions and, with the 900 and 1200 densities, load-bearing masonry.

EPS beads inside the concrete.
SMARTBLOCK® blocks are made with Edilteco’s Politerm® Blu: virgin expanded polystyrene beads of 3–6 mm, treated to bond with cement. The mix is vibro-compressed into solid blocks, with no holes or air cavities, so the block insulates throughout its mass.
From the 450 density upwards the mix also contains graded aggregates: more mass means more strength, a longer time lag and better sound insulation.

Six densities, one logic.
Lighter means more insulating; denser means stronger and more sound-insulating. Each density has its own page with every thickness, the data sheets and the specification text.

Block, mortar, equipment.

SMARTBLOCK®
47 items across 6 densities and 8 thicknesses, from 6 to 50 cm, with tongue-and-groove joints and hand grips.
The range
Malta Block 600
EN 998-2 thermal masonry mortar, class M2.5, λ 0.158 W/mK: the joint does not become a thermal bridge. One 50 L bag lays about 5 m² of wall.
The mortar
Equipment
ATHENA 515 band saw for dry cutting of blocks, ESB.MIX mixers and a polyurethane foam gun.
The equipmentThe rules of traditional blockwork, in less time.
The system is laid like concrete blockwork, with the lightness and interlocking joints that speed up the job: the ESB catalogue gives about 65 m² a day with the 33 cm block.

DownloadsFrequently asked questions
What are SMARTBLOCK® blocks made of?
Lightweight concrete: cement and virgin expanded polystyrene beads (Politerm® Blu and Blu Fein, 3 to 6 mm) treated to bond with cement. From the 450 density upwards the mix also contains graded aggregates. The blocks are solid, vibro-compressed, category II and CE-marked to EN 771-3.
How well does a SMARTBLOCK® wall insulate?
It depends on density and thickness. With the 300 density and 1.5 cm of traditional plaster on each side: 20 cm gives U 0.358 W/m²K, 33 cm U 0.227 W/m²K and 50 cm U 0.153 W/m²K. Compliance with local energy requirements must be checked on the project.
Which densities are load-bearing?
The 900 and 1200 kg/m³ densities, which have an average compressive strength of 5.5 N/mm². The data sheets indicate them for load-bearing masonry from a thickness of 15 cm. Densities from 300 to 750 are for infill walls, partitions and lining walls.
Which mortar are they laid with?
The first course on cement mortar, for levelling; all following courses with Malta Block 600, the EN 998-2 class M2.5 thermal mortar with λ 0.158 W/mK, which prevents the joint from becoming a thermal bridge.
