The Key Rama 3 is a 484-unit high-rise condominium by Land & Houses with sizes ranging from 29 to 61 square meters. The project is located near the Chaopraya river on Rama 3 road, approximately 12 km. from Charoen Krung intersection to Na Ranong junction at Klongtoey in Bangkok, Thailand.

The condominium is a fully precast concrete building with no cast-in-place concrete on its main structural elements.

This type of construction required less workers, materials like rebars, and concrete on the site, which resulted in a shorter construction period and fewer complaints from the neighboring community regarding noise and waste.

Grouted mechanical sleeves were used to join the precast elements, and Dextra Groutec couplers, installed inside shear wall and bearing wall, were an important part of the process.

“The half-grouted mechanism of Groutec L and S sleeves, which have a threaded end on one side, ensured accuracy and reduced mistakes during the grouting process” said Mr. Janeboon Leepipatnavit, Project Director of Taveeporn Technology Co., Ltd., the contractor of this project.

Mr. Janeboon further stated that Dextra was a reliable company with its own facilities in Thailand that could provide immediate support if required.
