Wall panels
One unit replaces steel sheets, studs, insulation and gypsum board: 100 to 300 mm thick, up to 6 m long, for internal and external walls.
One panel every 6 minutes, set by robot
AAC building
systems
Autoclaved aerated concrete walls, floors and roofs, designed, supplied and installed across Qatar and the Gulf for more than 25 years: blocks, wall panels and floor and roof slabs, in accommodation, villas, malls, hotels, schools and stadiums.
AAC walls,
floors and roofs
Reinforced AAC panels up to 6 m long go up in one lift: a two-person crew and one robot set a panel every six minutes, over 100 m² of wall a day.

Load-bearing system
or panel solutions
The full system carries the building on its own walls and slabs. The panel solutions fix to an RC or steel frame. Each family has its own page and its own catalogue.
The full system
Load-bearing. Wall panels, floor and roof slabs and lintels in AAC: complete buildings up to G+4 with no RC columns or beams. Accommodation, villas, extensions, garages, roofs.
Panel solutions
Non-load-bearing. Reinforced panels fixed to RC or steel frames: partitions, cladding, fire walls, boundary walls, design features and EIFS façades.
Five AAC
products
Cement, lime and silica sand, aerated and steam-cured, with the reinforcing steel set inside the panel.
Floor and roof slabs
Reinforced panels tied through the ring beam; replace hollow-core floors up to five storeys.
120 floor panels a day, set by crane
Blocks
600 × 200 × 200 mm, laid with thin-bed mortar that sets in about five minutes.
One-fifth the weight of concrete block
Fire blocks
Non-combustible: 150 mm gives 7 hours to ASTM, 4 hours to Qatar Civil Defence.
Fire walls at QP, RasGas and Ras Laffan
Lintels
Reinforced AAC lintels over doors and windows, cut to the opening.
Same material as the wall around them
Fire, thermal and
acoustic performance
AAC is inorganic and non-combustible, gives off no fumes in a fire, and insulates the building against the Gulf heat. Full data sheets, LEED calculations and studies come with a quote.

Wall panels
set by robot
Fully electric wall-panel robots lift, carry, stand and set each panel while a crew of two guides it from a tablet.
Our robots →Six sub-systems,
six sub-solutions
Six load-bearing sub-systems and six panel sub-solutions. Each has its own brochure with details and drawings, sent on request.
AAC system, load-bearing
- A
Accommodation
Complete AAC accommodation buildings up to G+4: wall panels, floor and roof slabs, no RC columns or beams.
- B
Buildings
Villas, compounds, hotels, schools and mosques built in AAC walls alone or in the full walls-and-slabs system.
- E
Extensions
Extra floors and extensions on existing buildings: light AAC walls and slabs that the old structure can carry.
- G
Garages & parking
Garages and car parks in AAC walls and roof slabs: light, fire-rated and quick to install.
- H
Hollow-core & AAC walls
Prestressed hollow-core slabs on AAC wall panels: longer rooms, the same light, fire-rated, insulated walls.
- R
Roof systems
Reinforced AAC roof slabs on any wall: 6 m spans, direct-paint ceilings, insulation built in.
AAC panel solutions, non-load-bearing
- C
Cladding
Reinforced AAC panels fixed vertically or horizontally to steel or concrete frames: malls, warehouses, arenas, schools and towers.
- D
Design features
Arches, parapets, pergolas, cantilevers and decorative façades, cut from the same AAC panels, slabs and blocks.
- EIFS
EIFS
Exterior insulation and finish systems over AAC: insulation board, base coat, mesh and textured finish on a wall that already insulates.
- F
Fire & lightweight blocks
Fire-rated and lightweight AAC blocks for towers, hotels, malls, tunnels and plant: four hours at 100 mm, one-fifth the weight of concrete block.
- P
Partitions
Intertenancy, corridor, shaft and service partitions in reinforced AAC: non-combustible, 34 to 77 dB, and as narrow as 185 mm with services.
- W
Boundary walls
Boundary walls in 6 m AAC panels on steel or RC posts: up to 9 m high, coated and painted direct.
