Concrete inside the Bamboo Connections

20150812-P1080417 - Staircase03

Bamboo usually breaks around the connection points, because the hole weakens the structure and being hollow it can just bend in half like a straw. To solve this problem we used a technique developed by Colombian Architect, Simón Vélez. It involves first bolting the bamboo, then drilling a hole next to the bolt and filling the entire node with concrete. We used a fairly watery mix to help it fill quicker, and vibrated the bamboo by tapping it to help it fill the space.
