Due to its flexibility and strength, bamboo structures are also earthquake resistant. Although, in the past, bamboo tensile strength has not been matched with a strong connection technique. To solve this problem, Sahabat Bamboo has been working with civil engineers and architects community in order to find the solution. We've tested many connection technique both in the laboratory and on the real buildings. Various school buildings, houses, gazebos and sheds have been erected.
Combination of strength materials, architects foresight, and the efficacy of preservatives have produce a robust and flexible construction, earthquake-resistant, beautiful and durable. Sahabat Bamboo is ready to serve you who want quality bamboo buildings, both small and large scale.
The main key for a long lasting and durable bamboo structure is a combination of preservation and design of the building itself. Preserving bamboo protect the building from the biological enemy such as powder beetles, termites and fungi. While the design it self must also be friendly with bamboo physical properties, means it should be able to protect it from moisture, rain and the sun's heat.
