It is a wall that, besides enclosing the space, carries the weight of the floors and the roof.

What it solves

It combines structure and enclosure in a single piece. With good mass it dampens the heat of the day. In seismic zones it needs reinforcement or confinement so it does not crack.

Today

Confine the walls with columns and tie beams at corners, intersections and the edges of doors and windows. Align the walls from floor to floor and distribute them in both directions.

Common mistake

Removing or opening a load-bearing wall in a renovation without knowing its function, which weakens the whole house.

Tomorrow

Compressed earth blocks made with hand presses in the community itself bring back interest in the load-bearing wall. Training local crews in their use is part of the project.

Fact In the 1985 earthquake in Chile, 76 percent of confined masonry houses were left undamaged.

Where it comes from

Masters

  • Anna Heringer METI School, Rudrapur, Bangladesh, 2005
    She raises the ground floor with thick walls of earth and straw made by hand by the community. The walls carry the bamboo upper floor and keep the coolness in the hot climate.
