No bricklayers needed. Just TABIPOR.
A 20 cm reinforced-concrete load-bearing wall with double Ø8 mm mesh, cast in formwork made of graphite EPS and OSB panels that stay in the wall as insulation: 20 cm of continuous insulation. Structure, envelope and insulation in a single phase.
Today's problem
First comes the structural crew, weeks later the bricklayer, and finally another crew for the insulation. Each trade with its own schedule and, in between, months of waiting. With TABIPOR one team erects, reinforces, pours and leaves the wall insulated, with no downtime between trades.
Reinforced-concrete houses · the system
Reinforced concrete, ribbed steel, graphite EPS and OSB board: traditional, CE-marked materials that any engineer knows. What changes is how they are put together on site. The sandwich panels act as permanent formwork and, once the concrete is poured, you get a solid load-bearing wall insulated on both faces.
Fluid C25 concrete, pumped, with a double 8 mm welded mesh prefabricated in our workshop. It is the load-bearing element of the wall.
10 cm of 30 kg/m³ graphite EPS and OSB board on each side of the concrete: 20 cm of continuous insulation, with no thermal bridges.
Light but sturdy. One worker places it by hand, with no crane or forklift. Pieces are joined with tongue-and-groove OSB splines and bonded with TABIPOR polymer.
The polymer with silica aggregate on the outer faces gives the finish a strong key.
Stone, facing brick or ceramic tiles are bonded directly with C2 tile adhesive.
If the finish is render, it takes its mesh like any ETICS.
Energy efficiency
The TABIPOR envelope reaches the insulation levels of cutting-edge passive buildings. Its 20 cm of continuous graphite EPS insulation, placed on both faces of the reinforced-concrete core, creates an envelope with no thermal bridges in the walls.
What does this mean day to day?
The house keeps the heat in winter and the cool in summer, with far less need for heating and air conditioning.
It drastically reduces heating and cooling consumption and bills, with a real commitment to the environment.
The mass of the concrete core provides excellent sound insulation, and the system's technical calculation rules out any risk of condensation in the wall.
Technical and commercial report
Summary of the TABIPOR technical and commercial report for architects, building engineers and contractors: composition, installation, thermal performance and tests.
Permanent sandwich formwork that acts at the same time as the concrete mould, thermal and acoustic insulation and substrate for the finish.
Thermal transmittance and condensation calculation according to NBE-CT, compared with a good-quality conventional façade: render, hollow brick, sprayed polyurethane, air cavity and inner partition.
| Parameter | Conventional façade | TABIPOR |
|---|---|---|
| Thermal transmittance (U) | ≈ 0.45 W/m²K | ≈ 0.20 W/m²K |
| Spanish Building Code CTE DB-HE, zone E (U ≤ 0.41 W/m²K) | Does not comply | Complies |
| Risk of interstitial condensation | Yes | No |
Values from the technical and commercial report, calculated with 10 cm of graphite EPS.
Report no. B0048-04-CM-043-3, Bilbao, 2 June 2004. Result: «Samples conform to the specified standards».

Turnkey house construction
We take care of everything, from design to handing over the keys. Reinforced-concrete load-bearing walls, a highly insulated home that spends little on heating, and a fixed price by contract.
Your plot, what you need and what you want to invest. You can start from one of our models or from your own design.
Leire and Kepa, from the Arkuri studio in Sopelana, draw up and sign the project and handle the building permit.
Detailed quote item by item and a fixed price by contract.
The panels and rebar for your house are made to measure in our workshop.
Walls, floors, roof, services, windows and doors, and finishes.
Your finished home, ready to move in.
Our architects
They design and sign every TABIPOR project. They work with the system from the very first sketch, so the design is born ready to be built quickly and without surprises.
Homes designed for your plot and your way of living, with the system built in from the start.
Direct contact with the architects throughout the process.
Every item measured and described, so you know exactly what you are paying for.
The price you sign is the final price of the build.
Five ready-designed models, single or two-storey, to get started sooner.
We adapt a model or design your house from scratch.

Structural shell for contractors, developers and architects
We supply and install the walls. We hand over the structure, envelope and insulation completed, ready for your crews to start the finishes.
An ETICS on its own, rendered, already costs about 110 €/m². For 350 €/m² of TABIPOR wall you get the reinforced-concrete structure, the envelope and the insulation, all installed.
| Conventional build | TABIPOR | |
|---|---|---|
| Trades to coordinate | Structure, brickwork and insulation | A single team |
| Formwork | Assembled, stripped and transported | It stays: it is the insulation |
| Insulation | Added later, by another crew | 20 cm built in from day one |
| Exterior cladding | Mesh, base coat and drying time | Direct with C2 tile adhesive |
| Interior | Metal studs for the plasterboard | Plasterboard screwed to the OSB |
We'll send you a cost and timing study for your project, with no obligation. You can also visit the workshop and see the system assembled.
ETICS with direct cladding, no mesh
The TABIPOR ETICS board comes from the factory with one face of polymer with silica aggregate. If the finish is stone, facing brick or ceramic, it is clad directly with C2 tile adhesive, with no mesh and no hassle.
With a render finish the board takes its mesh, like any ETICS.

A little history
Our journey began in 1985 as a family business dedicated to improving the quality of homes through the constant evolution of building systems.
We come from traditional construction and trade coordination, a period in which we experienced first-hand the usual problems of the sector: constant delays, technical issues and a bricklaying model that is slow, messy and now obsolete.
TABIPOR was born from that experience and the need for change.
TABIPOR is the result of optimising traditional materials by combining them with an advanced solution. Our system gives you the unmistakable solidity of a concrete wall together with high-performance insulation. In a context marked by climate change, this allows us to offer very efficient homes that stay warm in winter and cool in summer with minimal energy use.
Assembly is so simple that it does not require skilled labour.
Denia, 2005: the first complete house built with the system, built as a family.
We will share the build week by week, from manufacturing in the workshop to handing over the keys. Follow it to see how a TABIPOR house is built.
