Groutec is a mechanical splice specially designed to connect pre-cast concrete elements with each other or with structures made in-situ, both horizontally and vertically. At the pre-cast factory, Groutec is connected on one end to a threaded rebar. For this connection, the Bartec, Rolltec and Griptec systems can be used. The coupler is then casted in concrete. The continuation bar is then inserted into the sleeve which is then filled with nonshrink grout to complete the connection. The same coupler can be used as standard splice to connect bars of identical diameters and as transition splice to connect different bar sizes. Groutec is designed and manufactured in compliance with Eurocode 2, BS 8110, ACI 318, IBC and AASHTO.
Groutec, the grout sleeve for the concrete precast industry
Groutec is a mechanical splicing system featuring both a threaded end and a grouting sleeve. It is especially designed for the connection of precast concrete elements. Groutec is designed and manufactured in compliance with Eurocode 2, BS 8110, ACI 318, IBC, AASHTO.
How does it work?
Groutec connects precast concrete elements in two steps:
At the precast factory, the Groutec couplers are screwed onto the reinforcement and positionned against the formwork. Reinforcement is then cast in concrete.
On site, precast elements are connected by inserting protruding bars from the first element into the Groutec sleeves of the second element. The connection is completed by using non-shrink grouting mortar, injected through the injection holes, or directly poured into the cavity by gravity.
Coupler dimensions (mm)
Groutec precast couplers can be used to connect elements horizontally or vertically (by gravity or injection).
We recommend it to connect easily all your precast column and wall precast elements.
Pre-cast assembly with Groutec
Along with Groutec sleeves, Dextra also supplies a full range of precast accessories. Our range includes in particular magnetic or screw-type formwork positionners.
