At Greencrete Manufacturing, we are passionate about revolutionising the construction industry with our sustainable, efficient, and high-performance walling solutions. As a proudly South African company, we are dedicated to providing innovative products that not only meet but exceed industry standards. Our commitment to environmental stewardship and cutting-edge technology drives us to create building materials that are both cost-effective and eco-friendly.
Product Density
The product is mould resistant and doesn’t emit any toxic fumes when cut or exposed to fire. Due to Greencrete Manufacturing density, the acoustic performance between adjacent rooms is excellent, creating a solid “knocking” sound while eliminating the unwanted hollow sound created by drywalling and other board walling.
Efficient Operation
Greencrete blocks are suitable for most building applications. Quicker installation and a cleaner working environment ensure better quality and bigger savings on projects. The technology is a green initiative, offering additional advantages to the client and the end-user.

Why Greencrete Manufacturing?
Cost saving:
A cost comparison calculation was done on a typical 8 storey building. An estimated saving of 20% or R1 619 550,00 was calculated on the concrete and steel reinforcing as per the calculations & breakdown that follows:
Weight factor:
With each block weighing just over 15kg per block it is easy and convenient to handle and work with.
Time Factor:
With its lightweight characteristics of the Greencrete block it is much more efficient to work with. By laying one Greencrete block it is similar to laying 13 of the conventional clay/stock bricks.
Thermal and Acoustic Properties:
High density polystyrene and perlite used in the product delivers a unique end result with improved thermal and acoustic properties when compared to other walling materials and systems.
Fire Rating:
With an official rating of 120 minutes. The Greencrete Manufacturing block can withstand fires for 180 minutes or more making it the best in its class.
building Process
Foundations & Surface Beds
Foundations & Surface beds are built using traditional strip footing or raft surface bed methods. A competent person classifies the site in accordance with the site class designation set out in Table 3 of the South African Institute of Engineering Geologists (SAIGE) publication entitled Guidelines for Urban Engineering and Geological Investigations.
In abnormal or problematic ground conditions, foundations are designed by a professional engineer in accordance with the requirement of SANS 10161 and constructed in accordance with design.
A bituminous damp-proof membrane in accordance with SANS 952 or one covered by a valid Agrément certificate is applied under the external walls on top of floor.
Wall Modules
After the construction of the foundation and surface bed or raft, the galvanised light gauge steel bottom channel is fixed to the dust free concrete surface covered with bitumen using 10mm Ø x 80 mm Hilti anchor bolts or chemical anchors at 600 mm centres. A thin layer of tile adhesive is applied at the bottom channel, gluing the bottom modules to the channel. The bottom modules are then alternately staggered to the bottom channel of the outside and inside of the wall modules.
Middle and top wall modules are then secured onto the bottom and adjacent modules by using the tile adhesive in stretcher bond fashion.
The top channels are installed onto the last block course.
Channels are also installed to all vertical sides of window & door openings.
All the external & internal walls are wrapped with sheets of glass fibre mesh secured to the wall with a staple gun(roughly 5 staples per m2). The wall is then “bagged” with a mixture of plaster sand, cement and a bonding liquid. Ensuring that all mesh is covered propperly.
The walls are now ready to be plastered & painted, tiled or cladded as per normal construction procedures.
