Dextra’s Quarterly Newsletter: Connection #29

The condominium, which is located near the Chaopraya river on Rama 3 road in Bangkok, Thailand, contains 484 units.

Grouted mechanical sleeves were used to join the precast elements, and Groutec couplers, which were inserted inside the shear wall and bearing wall, played an essential role to ensure the reinforcement continuity with dry joints.

The half-grouted mechanism of Groutec L and S sleeves, which feature a threaded end on one side, ensured accuracy and reduced mistakes throughout the grouting process,” stated Mr. Janeboon Leepipatnavit, Project Director of Taveeporn Technology Co., Ltd., the project’s contractor.

The construction required fewer workers and supplies such as rebars and concrete, resulting in a shorter construction period and less noise and waste.

Groutec F IAPMO certified!

Groutec F precast couplers have been successfully certified with IAPMO (International Association of Plumbing and Mechanical Officials) Standards, following the previous certification of Groutec L. 


Groutec F is a new fully-grouted precast connection solution that is developed to complement the existing half-grouted systems: Groutec L and Groutec S. Unlike the previous two models, it is designed for the connection of precast elements without the need for any rebar preparation.
