SIACOT Chile 2013

El 13° Seminario Iberoamericano de Arquitectura y Construcción con Tierra (SIACOT) Valparaíso 2013, promovido por la Red Iberoamericana PROTERRA y organizado por el instituto profesional Duoc UC de la Pontificia Universidad Católica de Chile a través de su carrera de Restauración Patrimonial, tiene como finalidad reunir a los científicos, profesionales y técnicos que trabajan en torno al tema de la arquitectura, conservación y construcción con tierra, interesados por los amplios potenciales de este material. Se trata de una oportunidad de difusión y discusión, donde se evaluarán el estado actual de la investigación científica, de los proyectos, e innovaciones tecnológicas en marcha, así como los avances globales de la difusión de esta temática.

Bricks From Volcanic Ash

After weeks of enduring the ash brought on by Chile’s Puyehue volcano, one Argentine woman has decided to transform the grey sediment into something useful. Maria Irma Mansilla used the sediment and sand spewed by the volcano to create bricks. She hopes she and her neighbours will be able to produce them on a large scale to build homes for the poor.

Arquitectura Con Tierra en Uruguay

Arquitectura con tierra en Uruguay is a book that offers a tour of fifteen case studies of buildings constructed with earth in Montevideo, Canelones, Maldonado, Rocha and Salto, Uruguay. One of the most significant characteristics of this type of construction technology in Uruguay is the amount of new work, which makes a difference to other countries in the region. This publication presents the works of several architects and builders from 1996 to 2009 in a compilation of 250 photographs and charts.

Arquitectura con tierra en Uruguay makes clear the living traditions of ancient technologies that are increasingly valued. This book is available in Uruguay in the Faculty of Architecture Library (Bulevar Artigas 1031, Montevideo) and in the Library of the Society of Architects of Uruguay (Gonzalo Ramírez 2030, Montevideo). It can be purchased elsewhere through

Greenhouse Atelier

The Greenhouse Atelier, designed by al bordE, in Machachi, Ecuador is a shelter designed to express the powerful reflection of nature in the client’s paintings. The atelier is a “bubble” suspended between stone walls and rammed earth.

The existing space between walls, ground and bubble, protect the space from absorbing the humidity of the moorland. Additionally the first sun rays heat a radiator system that increase the temperature of the air gap. This heated air enters the space making it thermally comfortable. In the afternoon the main façade absorbs the sun heat, saving it in the solid floor of the workshop releasing the heat during the night.

Earthquake Proofing Traditional Peruvian Houses

Since 1970, Peru has been hit by five powerful and deadly earthquakes. The latest struck Peru’s coast exactly two years ago with a magnitude of 8.0 on the Richter scale. It fiercely shook the capital Lima, but its devastating epicentre was about 200km (124 miles) to the south, near the town of Pisco, a small fishing port built largely of adobe – mud bricks which Peruvians have used for thousands of years. For Peruvian engineer Marcial Blondet, it was the devastating quake in 1970 that first motivated him to develop earthquake-resistant buildings, particularly for those who could least afford them. Mr Blondet and his team found a solution in an industrial plastic mesh used by mining companies to hold back earth on slopes. It is strong, cheap and easy to use. Securely enveloping a normal mud-brick home in the mesh can prevent the walls from collapsing in an earthquake. The building wobbles but it does not fall down.

Casa Entre Muros: A House Between Walls

The Casa Entre Muros, built in Tumbaco, Quito, Ecuador and designed by al bordE Arquitectos (David Barragán and Pascual Gangotena), was generated from the starting point: “There is always another way of doing things and another way for living”. Far from the pollution of the city, the house is set in the hillside of the Ilaló volcano in a indomitable land. It’s limited by two streams opened to the landscape of the valley. A cut in the sloping land helps to generate a platform for the project and also to get enough raw material to build the massive party walls.

The waving form as a result of this cut in the land, defines the position and order of every wall. The succession of rammed earth walls and the different heights of the roof caused the division of the house even for the activity or the user. To avoid the domino effect, the party walls break their parallelism solving the structure and strengthening the character of each space within. A long corridor is used as an element that isolates the project from their immediate neighbours and reinforces the autonomy of every space.

This architecture aims to highlight the nature of the material elements that compose it, promoting the aesthetic, formal, functional and structural qualities as well as the maximum respect of the environment.
