C-MAX Technology

C-MAX® Technology is based on the production of construction panels. The C-MAX® panels are produced within a state of the art production facility in Kenya and software to make the most advanced EPS (EXPANDED POLSTYRENE SINTERED) PANEL

C-MAX® Advanced Building System is an amazing technology where columns and beams are not required, the entire system works as an integrated compact unit to maximise its strength and to bring various advantages that never before could be achieved. Buildings constructed using the C-MAX® technology have the following benefits over buildings constructed using traditional building methods:

Benefits To The Builder

Cost Effectiveness

Compared to traditional products, C-MAX panels achieve far better results, at considerably reduced cost. A building framework constructed using the C-MAX building system costs roughly 30%* less than a traditional one with similar features. The shorter build timesclaes represent additional savings. * refers to builds using PSMØ2.5 panels

Speed Of Installation

The C-MAX® system has been used in countless building experiences, in diverse conditions, and with all types of labour in many countries worldwide. These building experiences show a marked reduction in construction time compared to traditional building methods. C-MAX® panels are industrialized, and for this reason, assembly processes are optimised, labour is significantly reduced, and construction time decreased by roughly 40%*. * refers to builds using PSMØ2.5 panels

Lightness Manoeuvrability and Transportability

Being light weight, yet at the same time rigid, C-MAX® panels are both easy to handle and transport even in the most adverse conditions. Prior to an application of shortcrete, an C-MAX® panel weighs between 3.5kg/mq to5 kg/mq which means that a single worker can easily handle a *3sqm wall, that is, a panel as high as the storey height.


The C-MAX® building system gives full design flexibility as it offers a complete range of building elements such as load-bearing walls, curtain walls, floors and stairs. The panels are easy to use in the construction of any type of structure, and can be shaped to any geometric requirement – flat or curved- by simple cutting, on-site. C-MAX® is an extremely versatile building system which is completely compatible with all other existing construction systems; in fact, C-MAX® products are even suitable for completing reinforced concrete or steel structures. In addition, C-MAX® products can be easily anchored to other construction elements, such as steel, wood, and pre-stressed concrete.

Wide Choice Of Finishes

Buildings constructed using C-MAX® panels can be completed in a variety of finishes, or can be painted traditionally on smoothed plaster. The surface of the walls has the appearance of a thin sheet of reinforced plaster that can easily accommodate all types of wall coverings including stone tiles and rainscreen cladding.

Benefits For The User

Thermal Insulation

C-MAX® constructions perform brilliantly in both insulation and load-bearing functions: the thickness and density of the panel can be customised to deliver specific thermal insulation requirements. Furthermore, the EPS core extends throughout the surface which makes up the building envelope eliminating thermal bridging. For example, an C-MAX® PSM80 wall with a finished thickness of about 15cm provides the same thermal insulation as an insulated solid masonry wall of about 40cm, with obvious advantages in terms of additional space. Coupling with sound-absorbing materials (such as plasterboard, cork, coconut fibre, rock wool, etc.,), further optimizes the acoustic insulation of those walls, in compliance with the most stringent regulations.


Lab tests carried out on full-size prototype houses determined that C-MAX® structures withstand, completely undamaged, earthquake loads superior to seismic safety requirements. The prototype houses were also tested using both artificial and natural accelerograms with peak values over 1,0g, and came through unscathed. The results obtained in the lab tests represent the scientific confirmation of what has repeatedly been observed in real-world earthquakes. Buildings made using C-MAX® panels are particularly lightweight, so have a low seismic mass, but are at the same time rigid due to two sheets of reinforced plaster that interact to create an enveloping 'shell' of the whole structure.

Energy Efficiency

The C-MAX® building system constructs buildings which achieve high levels of energy efficiency which conform to energy efficiency regulations thanks to the insulating envelope provided by its polystyrene core which eliminates thermal bridges and ducts within the panel. The C-MAX® system provides significant improvements in indoor thermal comfort by greatly reducing energy consumption and promoting strategies aimed at sustainable development as established by analysis on a prototype which show a reduction of 60% in carbon emissions when compared to traditional buildings.

Load resistance

Numerous lab tests, performed in different parts of the world, have highlighted the high load resistance of the C-MAX® panels which after compression testing with centred load performed on a single finished panel, 270cm high, have shown they withstand a maximum load of up to 1530 kn/m ˜ 156 ton/m. The monolithic joints of the C-MAX® building system provide a high level of structural strength to buildings.

Fire Resistance

The quality of the foam polystyrene used for our panels is self-extinguishing and is perfectly encased by layers of reinforced concrete which coat the sides of the panel and inhibit combustion. Fire resistance has also been verified in tests performed in various laboratories. For instance, a wall erected using a PSM80 provides ReI 120 fire resistance, which means that for 150 minutes, the panel proved to be R = stability, E = resistance to fire and smoke, I = insulation.

Cyclone Resistance

Throughout the years, buildings constructed using the C-MAX® system in cyclone prone areas have demonstrated their capacity to withstand the passage of the most destructive cyclones. Laboratory tests, conducted on C-MAX® buildings, to determine the resistance of cyclone impact and damage caused by wind- borne debris confirm the strength of the building system. The tests are in compliance with U.S regulations for cyclone speeds of up to 106,2 km per hour.

Blast resistance

A series of tests has been carried out on a variety of C-MAX® building panels finished in different types of high strength concrete. The tests were conducted using a powerful explosive, in a test chamber optimized to produce uniform shock waves on the face of the panels. The C-MAX® panels performed excellently withstanding explosions of 29.5 tons/sq m.

Methods of Construction

  • Easy handling and rapid assembling.
  • C-MAX® Panel are easily hand transported by one or two operators.
  • This facilitates the installation and the speed to carry out the work in any situation

Preparation of the facilities

Thanks to their remarkable light weight C-MAX® Panel are easy and rapid to handle during installation process. They can be placed by hand and connected one to another with either pneumatic gun or ordinary building wire.

The set-up of the system is easy, fast and clean, since it does not require any masonry work. The chases in the polystyrene are carried out by hot-air gun and the canalization of pipes are carried out before the plastering to avoid dirt and extra work. In case of rigid pipes the metal is cut, is important to replace and restore the mesh to give the continuity of the metal around the structure.

Chases are made by melting polystyrene behind the meshwork by means of a hot air gun or any other source of heat. For rapid and easy of pipes(electricity water gas etc.)

Plaster application

Once the panels have been joined and the plumbing and electrical system have been completed, the plastering can commence. Two layers of concrete are required for both sides of the panel - approximately 3.5 cm layer each. The advantages of the C-MAX® system is evident. In addition, since there are no patches of the systems the plaster will turn out to be homogeneous and improved as for quality and even from an aesthetic pint of view.
