How it works

The building site became a factory.

AFDC didn't speed up the site — it replaced it with an industrial process. The panel isn't cast in a mould: it's extruded, pressed, pre-tensioned. A concrete you can't make on site.

The industrial process

Extruded zero-slump concrete.

The panel is extruded in a continuous process — the machine mechanically forces and compacts a near-dry concrete over the pre-tensioned strands. It is not cast in moulds.

01
Extrusion
A continuous (slip-form) process: the concrete is forced and compacted by the machine, not poured into a mould.
02
Zero slump
A near-dry mix at a very low water/cement ratio (< 0.35 — Abrams' law). Almost no water.
03
Density
Mechanical compaction drives the concrete to a density impossible on site — extremely low porosity.
04
Durability
Dense, the concrete is impermeable: salt and chloride can't get in — the pre-tensioned strands don't corrode. Decisive on the coast.
05
Strength
High fck; with the panel held in compression by the prestress, it resists cracking. Strength by physics, not chemistry.

Pure concrete. No additives.

Our panels are made with no chemical admixtures or correcting agents. The strength comes from the process — compaction and a low water/cement ratio — not from chemistry. Purity, predictability and durability.

Declared at the top of Group I.

WALL90 C45 · FLOOR120 C50 — the top of Group I (NBR 8953). We declare the class that keeps the system in Group I; the dense extrusion delivers strength above the declared class — structural reserve, not a catalogue number.

From factory to site

Four steps.

Plan adaptation

We adapt the architect's plan to the modular P60/P30 logic, preserving the design intent.

Availability & production

Standard panels in stock; larger jobs produced in-factory at ±2 mm tolerance.

Flexible logistics

Pickup at the factory in Pecém (60 km from Fortaleza) or negotiated delivery.

Assembly & support

Your crew assembles; AFDC trains and supports on site. No specialist bricklayer.

3 people · 3 days · 171 m² ready for finishing

The assembly

This 80 m² warehouse went up in 2 days.

The end of the industrial line: the panel arrives finished from the factory and goes up by crane — tongue-and-groove, no mortar, no specialist bricklayer. A 3-person crew installs around 30 panels per day, with the right tools.

From assembly to building

The same building. Finished.

The walls going up in the assembly above belong to this two-storey commercial building — here, finished and in use. Mezzanine, floors, shelving and counters: all from the same panel system.

Services

Wiring and plumbing run through the wall.

The panel's hollow cores take the conduits and pipes — no chasing, no breaking, no damage to the wall. The work that weakens masonry walls here comes ready to receive.
