Design, supply and install subcontractor

Who we are

Go Green International has designed, supplied and installed green building systems across Qatar and the Gulf since 1995: Autoclaved Aerated Concrete (AAC) panels and blocks, Modified Clay Material (MCM) and terracotta facades, and 3D Concrete Printing (3DCP), with our own engineers and software developed at GGI.

180+ Autoclaved Aerated Concrete (AAC) projects
650+ Modified Clay Material (MCM) projects
49 Terracotta projects

School 08, Doha: the printed building finished

3D Concrete Printing (3DCP) School 08, Qatar: the largest 3DCP structure in the world, 20,000 m² printed in 6 months at half of our printing speed.

Our hybrid solution: AAC x 3DCP

GGI offers hybrid solutions: irregular geometry is 3D printed, and internal partitions and other walls are built in AAC.

Majlis concept on site: our 3DCP technology with the mixer-pump and hose, and the AAC installation robots. Concept.

3dcp printing mix

Compressive strength, 1 day: ≥ 10 MPa; Strong after one day
Compressive strength, 28 days: ≥ 35 MPa; High strength
Tensile splitting, 28 days: ≥ 3.5 MPa; Resists cracking
Density: 1,900–2,100 kg/m³; Dense, solid walls
Thermal conductivity: 1.8–2.0 W/(m·K); Insulation goes in the wall cavities
Shrinkage: ≤ 0.7 mm/m; Little shrinkage as it dries

Aac

Thermal conductivity: 0.12 W/m·K; Great thermal insulation
Compressive strength: 4 MPa minimum; Load-bearing up to G+5
Fire rating: 4 hr at 100 mm, Qatar Civil Defence; A 100 mm wall holds back fire for 4 hours
