ETE — Emergency Technical Engineering

Houses that withstand earthquakes and cyclones — strong, affordable and within everyone's reach.

Engineering in the service of vulnerable communities

ETE (Emergency Technical Engineering) is the engineering association where the Urgence Renouveau Haiti adventure began. As early as February 2010, its teams were on the ground after the earthquake: structural assessments, emergency shelters and training for local workers. To this day, ETE continues its mission: putting engineering at the service of the most exposed families by developing safe, durable and affordable construction solutions.

The micro-gabion technique

A simple idea, inherited from the gabions used for thousands of years along rivers: galvanised steel mesh cages filled with stones.

The walls are made of rows of gabions — an upper bed, a lower bed and vertical U-shaped panels — assembled side by side and completed with a wooden frame, floors and roof. The structure draws its strength from its ductile behaviour: like the gabions that protect riverbanks near fault lines, it absorbs and dissipates the energy of tremors instead of breaking. Its seismic resistance was scientifically validated in 2020 through discrete element calculations.

The technique in pictures

ETE has built with this technique in Morocco, in Haiti — the 50 houses near Jacmel — and in Nepal. Here, step by step, is how a micro-gabion build unfolds.

Why it changes everything

Earthquake-resistant

The flexibility of the gabions absorbs tremors: the house bends without breaking.

Cyclone-resistant

The mass of the stones and the anchoring of the structure withstand the violent winds of cyclones.

Affordable

Local stones, mesh and wood: simple, low-cost materials available on site.

Anyone can build it

No need for skilled workers: anyone can build it by following the step-by-step guide.

The project in Haiti, near Jacmel

In 2015, nearly 50 micro-gabion houses were built near Jacmel, in southern Haiti, in partnership with Architecture & Development and CRATERRE. Each house shelters a family of five: in all, nearly 250 people were housed. Five years after the 2010 earthquake, these Haitian families regained a safe roof, able to withstand the next earthquake as well as the next storm — and built in just a few weeks.

ETE provides a complete guide — foundations, framing, insulation, roofing, electrical work — so that anyone can understand and reproduce the construction.

Frequently asked questions

Does a micro-gabion house really withstand earthquakes?
Yes. Its strength comes from its ductile behaviour: the stone-filled cages absorb and dissipate the energy of tremors instead of cracking. This seismic resistance was scientifically validated in 2020 through discrete element calculations.
Why is it so affordable?
The materials are simple and available locally: stones, galvanised steel mesh and wood. No expensive concrete or heavy machinery — the essentials are found on site.
Do you need skilled workers?
No. The technique is designed to be reproducible by anyone by following the manuals step by step. It is also a way to train and involve local people in rebuilding their own village.
What about cyclones?
The mass of the stone walls and the solid anchoring of the frame allow the house to stand firm against violent winds — an essential asset in the Caribbean.

Support the action in Haiti

Urgence Renouveau Haiti and ETE have shared the same conviction since 2010: words alone are not enough, we must act. Your support helps Haitian families rebuild for the long term.
