The central core of the panel is made up of expanded polystyrene with a density of 15 kg/m3 – 25 kg/m3 that is cut in an undulated way to improve the adherence of the concrete when discharged.

The mentioned EPS core is flanked with meshes of straight and/or corrugated steel, depending on the kind of panel, which are linked together by a series of connectors that go through the EPS core.

Once the micro-concrete has been discharged, and because of the steel connectors, the panel will act like a compound section before the external loadings.

Baupanel® is not a prefabricated system. It could be much better defined as an industrialized or semi-prefabricated system, because the panel is made in the factory and delivered with the exact length according to its position in the building design. The micro-concrete is discharged on site.

The main advantages are:

• Greater flexibility in the building works if it is necessary to reform the project.
• The setting out can be done with lower accuracy than in prefabricated system.
• Since the micro-concrete is discharged on site, there is a total lack of joints (except for the structural ones each 40 m), etc.

Previously, it would be carried out by cutting up of the building, or detailed panellizing, with a list of the different types and lengths of the panels to be manufactured.

The Baupanel® System has no regulatory limitations regarding the height of buildings that can be built. The limitations only result from the respective structural calculation and other external factors such as the type of soil on which it should be laid.

Currently, Baupanel® System is the only 3D construction system in Europe that can be considered as a traditional rationalized system.

Baupanel® System has proceeded, as corresponds every 5 years to the renewal of its Technical Suitability Document No. 558/10 that remained in force until the issuance of the new document that was granted on February 15, 2017 with its new identification that adds the letter R and the year of issue: 558R / 17

Buildings using this system have been erected all over the world since the 1970s.

Baupanel® System has many applications. It is a system of load-bearing walls, but it is compatible with free plants using auxiliary concrete or metal structures that integrate perfectly with the system.

An example would be a very modulated residential building on all its floors with a diaphanous basement where the walls of Load have no place. The solution would be to use the structure in loading frames. In the Technical Department specific construction details have been developed for these cases, which have to be studied individually.

Another possibility is to use the system as a facade cladding in buildings with conventional structure, obtaining very good performance in the placement, as well as excellent insulation thermal and acoustic, as well as a gain in useful surface.

Yes. Simple Panels can be used as retention of land up to 3 meters high, according to the DIT. The panels would be of the kind BPR (with integrated corrugated reinforcement).

For greater heights, we could use the Double Panel type BPD (with a central core of armed concrete).

• Time saving (above all with repetitive elements).
• Cost saving (we can do without many heavy machinery traditionally used in the building works. Time saving is equal to cost saving).
• Personnel saving (very few people are needed to erect buildings).
• Energy saving (During the useful life of the building, there is an important energy saving thanks to the insulation capacity of the System and, therefore, we save money in conditioning).

Totally true, since we solve our facade walls by meeting the thermal and acoustic requirements of the CTE with only 17.50 cm, compared to at least 25 cm of traditional solutions. From the accumulated experience, we can affirm that a gain of 3 m2 of useful area is produced in a house of 100 m2 of constructed area.

The assembly does not require special knowledge of masonry, as it is very simple and methodical. The micro-concrete projection, on the other hand, does require some specialization in the handling of projection machines (plaster, for example).

In Spain, our technical team carry out on-site training and, after checking the learning, you can carry out approvals from authorized Baupanel® System installers.

On international building, we do provide our manufactured building materials and our technical printed guidelines, but we do train building companies on-site.

The mass of the walls built with Baupanel® System is approximately 180 Kp / m2 and that of the slabs is approximately 215 Kp / m2.

For external facings, we employ panels with a core of 10cm minimum of EPS that, together with the discharged concrete, with a wall section of 17,50 cm (taking into account an environmental exposure class IIa).

This thickness can be used in Spain without having to add any linings or cavity walls, as the thermal transmittance value fulfils the CTE DB-HE (Energy Save Basic Document Building Technical Code) standard in all the national territory.

Nevertheless, by clients’ request and due to design reasons, a greater wall thickness could be used.

If the panel works as a bending stress (as a land retaining wall) the thickness will be established by calculation in order to bear the earth pressure.

In the case of the frameworks, it will be carried out by a pre-dimensioning of the edge according to the main spans of the building to be built with this System. That section will later be checked by calculation. The maximum section of framework elements type BPF is 28 cm (5cm of compression layer, EPS core of 20 cm thick and lower concrete layer of 3 cm thick).

Very few people and machinery is necessary to build with Baupanel® System.

Two people are enough to erect a detached house of 100 m2 with one floor in just nearly 4 weeks. Furthermore, the building works can do without expensive fixed cranes and two people can easily move one panel.

In the assembly phase, the frameworks are supported by angular meshes and they are separated by a few centimetres from the bearing walls in order not to interrupt the concrete sections of the walls along its height; otherwise, the walls would have to be cut causing a weakening line on them along its vertical course.

It must follow the instructions of the EHE-08 standard where this matter is defined. It also depends very much on the weather.

Usually, the frameworks are left shored up for approximately 15 days, although it depends on the Project and Site Management’s judgement.

Baupanel® System has a special panel for movement joints or shared walls. The side facing the joint or the shared wall has a double mesh and the concrete is poured in touch with it. The side facing the inside of the building will be of discharged concrete.

The acoustic insulation rate of this panel is 51,30 dBA.

Previously, it is necessary to put a sheet of EPS with a thickness to be defined in the project in order to formalize the very same joint.

Calculations are similar to those of the known traditional system. Please, keep in mind that it is armed concrete dimensioned through the methods of material resistance already known in the technical field.

The bearing walls work by simple compression since the frameworks do not transfer momentums to the walls. Thus, it has been checked that in the most requested bearing line of the less favourable point of the building, the admissible tension of the used armed concrete is not surpassed.

The frameworks are plane elements working by simple deflection. The maximum momentum is calculated in the midspan and it is compared with the resistant momentum of the kind of panel chosen for that purpose. If the resistant momentum of the panel surpasses the momentum in the midspan, then it is not necessary to use reinforcements. On the contrary, if the momentum in the midspan surpasses the resistant momentum of the panel, it will be necessary to add reinforcements until reaching the demand of the maximum momentum.

It is necessary to calculate the longest openings of the framework until reaching the maximum lengths that do not need reinforcements.

Baupanel System is compatible with any kind of foundation usually employed. Depending on the land, it is likely used slab foundation in those buildings with an irregular load lines layout, and continuous footings in those buildings with a more uniformal layout.

HA-25 micro-concrete with a minimum resistance of 25 N/mm2 according to EHE-08 standard.

The maximum size of the aggregate is between 0 and 6 mm and it has a special formula based on plasticisers that makes the application and adherence on Baupanel panels easier. It is supplied dry, in sacks or in silos.  Its composition includes fibers that help to avoid the cracks by surface shrinkage.

The average thickness of the concrete projected on each face will be 4 cm. For more technical information on assembly and foundation, download our assembly manual at:

It accepts any kind of finishing, even facings with metal substructures.

No. We can use the usual ones in the market. It uses metal pre-frames for metal windows and doors, and wooden pre-frames for wooden windows and doors.

Installations are set up inside the EPS core before discharging the structural micro-concrete; thus, they are enclosed between the two layers of concrete.

It could happen that during the useful life of a building those installations suffer some damage that needs to be repaired. There is no problem, but it should be done with care.

With a radial machine, we can do a clean cut on the concrete layer to reach the damage and, after repairing it, restore the removed concrete. If the affected area is not very big, it could even be done without restoring the removed mesh.

If the channels are vertical, this is no problem, but in cases where they are horizontal, we must take the precaution of acting on the wall in a discontinuous way, above all if it is a bearing wall.

There is no problem to open hollows (whether for windows or doors) in non-bearing walls already concreted. It would be also possible to do it in bearing walls as long as a lintel is planned between the hollow and the ceiling so the stresses can be distributed. The mentioned hollows must be opened with a radial machine.

Unlike other systems, such as, for example, Pladur, Baupanel® does not need any special fitting and there is not any weight limit to hang objects up on the walls or ceilings.

Since the facings are of armed concrete, the only precautionary measure is to use specific bits for this material.

In order to carry out the AFS & ACS installations (cold and hot water) inside the Baupanel walls, we must employ pipes of plastic materials (polybutylene or polypropylene) because due to its flexibility they are easier to be set up.

Copper pipes are not suitable in this case due to its rigidity and the possibility of causing galvanic torque due to a hypothetical long contact with the steel meshes that are part of the panels.
