3. The Material
• differs itself from normal concrete because it gets a special light
weight out of encapsulated air. Air encapsulations can be
produced/reached by additional materials like polystyrene balls
(packaged air)
• For this normal concrete is used which is made out of cement,
water and sand. These basic materials get won from nature.
Base materials for the cement are lime and clay, which are
burned with high temperatures and grinded afterwards

transported to the building site and get assembled there. Out of
large sized prefabricated parts walls, ceilings and roofs are
made
• The walls can be made out of chopped wood and bagasse.
Nano colloid lightweight prefabricated
component parts
• By the prefabricating in the factory and very low raw densities a
clear advantage concerning costs is reached compared with
prefabricated parts out of normal concrete and conventional
solid construction methods

11. Our Process
Our innovative prefabrication process consists of integrating the static load bearing
system (framing construction method) into the production process of wall, ceiling,
and roof elements. In this process custom-built cold rolled iron light section elements
are used. By means of our patented process, the bulk densities of our wall
construction materials can be adjusted to the different structural-physical demands.
Even bulk densities of 350 kg/m³ do not cause static problems!
The light structural steel frame is completely filled and enclosed by lightweight
concrete. The result is a composite element with a high degree of bearing capacity
and fire resistance.
Our elements are delivered by default with finished interior surfaces which do not
require any additional plastering. If needed, ductwork for electrical lines, air
conditioning and other equipment can be pre-installed. Window elements, steel door
frames and other components are pre-installed prior to placement of concrete.

Estimated requirements for establishing nanotechnology prefabricated element facility :
Description
Production Capacity of wall and ceiling elements
min. 500 m² / day** max. 3,000 m² / day **
- Site Area 25,000 m² 45,000 m²
Including area for halls 7,500 m² 8,000 m²
- Access to public road network
- Connection to electricity supply 0.6 MW 0.8 MW
- Connection to water supply
- Wastewater and rain water drainage
- Personnel Administration and Engineering 8 employees 10 employees
Production 2x 24 employees 2x 30 employees
Picking and Loading 4 employees 6 employees
Transport and Assembly of elements * 12 employees 30 employees
-
-
(Not included in the investment sum are: fees, charges, duties etc. as well as production hall with cranes, administration and social buildings)
* Cost does not apply if outsourcing of these positions
** The daily production capacity can be incrased in steps of 500 m² each
13. Input / Output
Daily input requirement (at maximum capacity) :
approx. 500 m³ natural- und raw materials such as: sand, tuff, pumice
stone, EPS granulate, CM 500 or others
approx. 20 T steel
approx. 170 T cement
Our product only uses 30% cement
approx. 1 T chemical aggregates and other material dependent
upon configuration of requirements of prefabricated houses.
*The production time is set to 300 days per year, 20 hours per
day.
13
14. Daily production output:
Up to 2,400 m2 wall, ceiling and roof elements
Annual production output:
Approximately 200,000.00 m² usable residential
and commercial square footage
*Customized to individual customer demands
14
15. Cost advantages
Annual output per year of one our plants corresponds to an annual brick factory output of approx.
100 millions bricks in standard size.
The investment costs for a brick factory are approx. 35 million € and thus twice the amount of our
prefabricated element facility.
Advantages of Performance :
Cost advantage compared to conventional construction method = 15 %
Up to 45 % of total operating performance for housing construction are produced by our
prefabrication.
*Our product uses only 30% cement
*The remaining construction is carried out by 3 qualified companies:
Underground engineering (Excavation, base plate, site development: approx. 12%
Shell construction ( Delivery and assembly of pre - fabricated components): approx. 50
%

33. Walls
• Advantage: The wall
is the outer surface
are of the building at
the same time.
• Disadvantage:”Heav
y” constructions are
advantageous for the
static, but they have
disadvantageous
characteristics
concerning heat
insulation.
Skeleton
• Advantage: The
(supporting)
component parts are
designed optimally for
the static.
• Disadvantage: The
part of the building’s
outer surface area
(wall) has to be out of
a different heat
insulating material
and has to be
SYMTEC-
Porolith
• Advantage: The wall
is the outer surface of
the building at the
same time. The wall
(SYMTEC-porolith) is
the heat insulation at
the same time. The
lightweight steel-
structure basically
takes the static

39. Solid reasons for our construction method
Ecological Solid construction materials are made out of domestic raw
materials which saves energy and transportation costs
Cost-effective Efficient shell-techniques for prefabricated wall-component parts
guarantee a fast building progress. The good physical qualities
make compressed construction ways possible and save
expensive construction area
Durable Solid construction materials resist extreme weather even without
chemical protection paints. They distinguish themselves by
stability and durability
Stable Living space made out of solid construction materials are strong
and have long repair-intervals, a high resale value and
represents a considerable value for many generations.
Comfortable Solid construction materials are always caring for a good living
climate in summer and winter.
Undisturbed The formula of the construction material is adjustable. The
smaller the raw-density the better the heat protection is. High
raw-densities fulfil the demands of sound protection.
Safe Waterproof, frost-resistant, fire-resistant , & able to be recycled
completely
