FOUNDATION
Our buildings, among their many advantages, have the characteristic of being self-supporting and lightweight.
These two characteristics mean that the foundation requirements are minimal, since they do not exceed a load of more than a few hundred grams per square centimeter.
The reinforced concrete slab is the ideal solution, because it is possible, at the same time as building it, to insulate it thermally, to make it the sanitary slab, to act as a substrate for the various conduits and the base for the flooring, heating, etc.
Other solutions are also accepted, such as continuous beam foundations, braced shafts, pile foundations, etc.
In the example on the left, we can see what would be a suitable slab foundation solution, while at the same time complying with the requirements of the CTE.
Reinforced concrete slab
Manufacture in concrete plant (HA-30/B/20/IIb) and pouring on site.
Reinforced with EM 15X20 electro-welded mesh, diameter 8 mm, and 10 mm reinforcements.
Steel type B 500 T 6X2,20 UNE 36092.
Expansion joints grouted with cement grout 1/3 CEM II/A-P 32.5 R and cleaning, according to NTE-RSR.
STRUCTURE
The assembly of the structure is carried out on the slab, set and leveled (although the system allows for substantial variations in this regard).
After the staking out, the different pieces and assemblies that make up the structure are formed; porticoes, brace braces… However, in an extremely simple way, assembling the pieces and screwing them into the knots, without the need for brackets or other adjustment elements, since the knots themselves “drive” the bars to the appropriate angles.
The fixing of the structure to the foundation slab is carried out in two phases:
In the first one we anchor it by means of special pieces (see details of pieces, below), which fix a mechanical grip by means of special high-strength bolts.
In a second phase, we embed part of the nodes, supports and steel braces in a high-strength mortar, which will serve as the base of the pavements (see points 04 and 10).
The resources necessary for the assembly of the structure are reduced to a minimum for several reasons.
L he weights that are handled are very low because we always work with light individual elements.
The assembly is self-driven in terms of the angular positions of the parts, and it is not necessary to cut at an angle or “square”.
A ratchet, open-end wrench, drill and riveter (and not always) are all we need to assemble it.
CLOSINGS
The
enclosures
are made of steel Sandwich Panel, with polyurethane filling, of the type used for cold rooms.
This panel has a high mechanical resistance and full guarantees of watertightness on any structure, in addition to the highest specifications in thermal insulation.
The thickness is 100 mm, which gives the building a spectacular insulation coefficient.
The useful width of these panels is 1 m, tongue and groove and perfectly sealed between them and the structure.
Its high solidity collaborates with the structure, giving the building a self-supporting character of very high resistance, insulation and durability, as well as a practically inexistent maintenance.

The
ease of assembly
of these enclosures is due to the fact that we have applied in their design all our experience in this field, which goes back several decades, and to which we have been incorporating those of third parties.
Everything has been foreseen; every detail has been worked out in advance and all the necessary accessories have been designed and manufactured for a quick and perfect assembly.
COVERS
The roof is one of the fundamental elements in ensuring the strength, durability and comfort of a house. That is why we have taken the utmost care in its design and efficiency, making a functional product that improves even the highest expectations for a modern home.
In this case it is a set of elements that collaborate in the thermal and acoustic insulation of the building, being at the same time self-supporting and light, perfectly waterproofed and collaborating in the resistance of the house as a whole.

WALL LININGS: CEILINGS AND PARTITIONS
Rigid building envelope panels are based on gypsum panels (commonly called Pladur); they are light and easy to handle, they allow to create any shape, they can be applied on any surface and at any angle or inclination.
The facade linings provide structural resistance to the whole, and also provide substantial improvements in terms of insulation, by breaking thermal and acoustic bridges.
The illustration on the right shows a section of a facade wall. It is possible to appreciate how all the elements are arranged to give as a result a unique, solid set that works in solidarity with the rest of the pieces of the house.
We can observe the following pieces and elements that make up this set:
- Gypsum board (Pladur)
- Exterior façade panel
- Upper sealing channel
- Lower channel receiving Panel
- Isolation
- Plasterboard fixing omegas
- Omegas fixing uprights
With this base we can easily build the partition walls, which are called “dry” type, since no mortar (and, therefore, no water) is involved in their execution.
In the partition walls, gypsum boards are placed on both sides, reinforced and supported by a metal framework, as shown in the image on the right.
In the illustration below we see the following elements:
- Gypsum board (Pladur)
- Mounting jambs
- Upper and lower channels
- Thermo-acoustic insulation
- Door preframe
Ceiling linings also provide structural resistance to the whole, as well as substantial improvements in terms of insulation, due to the breakage of thermal and acoustic bridges.
In the illustration above we see the detail of an assembly showing the following elements:
- Omegas fixing uprights
- Plasterboard fixing omegas
- Gypsum board (Pladur)
FLOORS AND PAVEMENTS
Flooring and paving make up a fundamental element in ensuring that our buildings achievethe best performance in terms of comfort and energy efficiency through thermal and acoustic insulation.
That is why we incorporate the latest technologies and market advances to achieve the highest standards.
The inclusion of underfloor heating means that the floors incorporate the following elements:
- Foundation slab
- Plastic piping with oxygen diffusion barrier. Made of polyethylene or polybutylene, especially for this heating system.
- Insulating panels on which the pipes are installed, with a moisture barrier between the subfloor and the radiant floor emitting surface placed on top.
- Cement mortar, with a recommended thickness of 5 cm measured from the upper generatrix of the pipe.
- Pavement. It can be of any type and material available in the market.
VENTILATED FACADE
Ventilated facades are a magnificent solution to thermodynamically support the already high insulation of these buildings.
As they are separated from the facade panels, they allow constant thermal air movements, which improve insulation and prevent heat or cold accumulation.
The illustration on the right shows how a ventilated facade is assembled and how it behaves.
On the framework of the vertical (2) and horizontal (1) profiles in “Omega”, we fix the fiber cement panels (3), which keep a considerable distance between the facade panels and these.
When the sun shines on the fiber cement panels (3), they radiate heat towards the interior, causing a “chimney” effect between the façade and these panels, raising the hot air out of the framework (5) and allowing fresh air to enter from the ground (4).
It also acts in reverse, preventing cold air accumulation.
And it contributes to the acoustic insulation of the building, with a sound wave dissipation effect on the exterior panels.
