SYSTEM

WallTech is a construction system which is versatile, Safe, profitable and fast. Walltech is a great opportunity to revolutionize the industry with an alternative building system that combines the effectiveness of building materials with innovative processes; as well as designing flexibility for practically any type of housing. WallTech has grown to be a global leader in design and construction of residential and commercial buildings.

Our system is a unique modular system of industrially fabricated panels for walls with multiple uses and applications that reduces building time and cost up to 70% and 12% each. Just like with any traditional system, it is compatible with any wall finishing. The system is the result of a serious analysis, designed to obtain an efficient and economic solution that:

  • Exceeds structural regulations
  • Adapts to today’s demands
  • Maximizes human resources, materials and technology
  • Optimizes building times

Our system has shown to be a superior structural option compared to traditional systems. It can also be easily combined with traditional systems. WallTech system can be used to build up to 4 story buildings by itself. It can also be combined with traditional sysyems to be used in higher constructions and towers to lower the weight, decrease the cost and increase the safety.

WallTech has a presense in most dynamic markets in the world, including Latin America, Africa, Europe, Asia, and the Middle East.

WallTech panel is a self consistent structural construction system. This system fulfills all the required structural characteristics for industrialized housing construction. Our system consists of panels composed of a structure of steel rods with an electro welded metal mesh. Our panels are made to fit any project size, starting from its fabrication including preparations for doors and windows as well as the roof falls. At the construction site, the panels are joined with connectors which are parts designed and manufactured from the same steel as the panels, and are positioned every 30 centimeters. Panels have a preparation on the upper part that serves as a closure to receive any constructive system that could be used on the stone slabs.They will be filled with the reinforced mortar which has a thickness of 2.5 centimeters on each side, from which 0.5 centimeters is introduced inside of the mesh, creating an empty space in the center which functions as a thermic and acoustic isolator. The Reinforced Mortar is a mortar made of sand, lime and cement, which is reinforced with expanded metal and a steel truss. This trusses can be made off very thin, but very resistant steel bars.

WallTechZ Panel
  1. Lintel (10cm thick)

  2. Horizontal (2.75mm) and vertical (4mm) high strength steel reinforcements (at 30cm / 40cm | Fy=4,500kg/cm2) protected with anticorrosion alquidalic painting

  3. Expanded metal (0.32mm Thick | f’y= 2400 kg/cm2 | GAUGE. 26) protected with anticorrosion alquidalic painting

  4. Covered with reinforced mortar on both sides (2-3 cms per side | f’c= 150 kg/cm2)

Our panels have 3 main characteristics:

Industrial Manufacturing

Our industrial manufacturing guarantees quality and allows customization for different specifications, giving a better performance than traditional systems, and a more secure supply of materials.

Monolithic Structure

Our panels are fabricated in a metal electro-welded structure, bonded with metallic elements, covered with the reinforced mortar, without the need of beams and pillars.

Metallic Mesh Conformation

Our panel’s dimensions vary according to the house design; they replace the frame structure, ease the incorporation of installations, and comply all the soundproofing and heat transfer indexes. They are also seismic resistant.

The construction process with our system is very simple. It starts with a leveled and compressed terrain, excavation and placement of the steel mesh for the foundation below the spot where the wall panels are going to be installed. Immediately the panels are set up, bonding them with steel connectors, forming the joints of the house. Once the walls are in place, the mortar is applied over the panels. In case of a building with two or more floors, any slab system can be used with the same kind of panels and connectors. The roof can be of any type of structure. Our system is compatible with all wall finishes like:

  • Pastes
  • Texturization
  • Paint
  • Ceramic
  • Among others

With our system, you can build a two-story house in 9 days and a one-story house in 5. Our system is ideal for all housing projects in series. Please note that the time each step takes in our building procedure, highly depends on the size of the project and some other factors. Below we are giving some proven estimates for a 136 square meters two-storey residential building. Our team of experts will assess time for each project based on its elements and factors before the procedure begins.

  • Simple work execution
  • Optimize time, human and economic resources
  • Improve quality life for the user

There are many benefits to our system. Below is the list of some of the most important features that make our system stand out among all other candidates in the market.


Our System Has Passed ALL KINDS OF TECHNICAL TESTS That Guarantee Safety & Resistance

Our system is highly Seismic Resistant


Constructing buildings to be earthquake-resistant is expensive – structures often use imported high-grade steel and engineered timber framing. The costs are a barrier to construction for developers looking to make a margin on sales or rental when the building is complete. Many tests have been carried out on buildings built with WallTech system. WallTech system has proven to be highly earthquake-resistant. Below shows Earthquake Simulation on a four-story building built with WallTech system.

To test the seismic performance of the new WALLTECH structural system - a two-story monolithic building, Beijing HUAJIANBIAO Technology Development Center of Architectural Standards entrusted the National Center for Quality Supervision and Test of Building Engineering with the test of the seismic performance of the new WALLTECH structural system - a two-story monolithic building. The test was executed on a 6m×6m seismic simulation shaking table on September 13, 2010 in China. The shake table simulated both vertical and horizontal earthquakes at the same time.



As mentioned in the report, there were no obviously abnormal changes observed externally in structural components and joints of the two-story building model throughout the test procedure. There were also no obvious failures and cracks on the internal and external walls and roofs. The model was intact. The results show that the two-story building model has features of light, stiff, high natural frequency and low story drift. It shows a great capability against the simulated seismic force so that it could be suitable for those areas of the earthquake fortification intensity 9 or below. As you see, not even slightest amount of damage was done to WallTech system during tests. So our system has provent to be definitely of much better performane than any other available solution in the market, considering.



Our system is highly Impact Proof


WallTech Panels are able to withstand intense force or shock applied to them over a short period of time. Impact resistance is an important consideration for fall protection equipment. Our Impact-Resistant Panels reduce potential damage which can provide significant cost, labor and maintenance savings because of its life-cycle efficiency and other important benefits.

To carry out the system analysis, diverse modules were carried out, using analysis techniques such as the ones indication on the Detailed Masonry Method and matrix methods based on the Finite Elements Techniques (FEM). The intention in using the Detailed Masonry Method is find, with other information, the participation of seismic forces on each wall. With the Matrix method (FEM) the distribution and flow of forces in the panels was analysed likewise with the revision of the forces on the connections.

  Seismic forces obtained with different types of soil and only one floor, this is only with the WallTech System.

WallTechZ Seismic

  Seismic forces with different types of soil and with two levels, this is with the WALLTECH system used on the first floor and the traditional system used on the second floor.

WallTechZ Seismic

The mathematical matrix models simulate the behaviour of the panels through plates of 6 degrees of freedom for each knot, in such a way that the mechanical elements and forces on the interested zones can be obtained. Using Gauchy’s convention of signs.

WallTechZ matrix

Matrix models allow us to see the effort distribution on walls and foundation. To distribute the seismic shear stress master knots were used for the application of seismic eccentricities.

WallTechZ matrix

The second level was also modelled with a different material than the panels with masonry mechanical properties. Even though the elastic/lineal material is considered, tensions levels that can be appreciated, will provide us with hints of where to put special care on revisions and reinforcements. These models are made out of 4093 shell elements and 4067 nots with a 20177 degrees of freedom.
