Product 05 - Grout Coupler System

Grout Coupler
System

A precision-engineered grouted sleeve coupler for full-strength rebar continuity at precast and cast-in-situ joints - no torquing, no welding, just a reliable grouted connection.

Kridhan Grout Coupler System
Product Overview

What Is a
Grout Coupler?

A Grout Coupler is a cast iron or forged steel sleeve into which deformed reinforcing bars are inserted from both ends. The annular cavity between the bar and the sleeve is then filled with high-strength non-shrink cementitious grout, creating a permanent, full-capacity mechanical splice.

Unlike threaded mechanical couplers, the grout coupler requires no bar preparation, no threading, and no torquing. The connection is especially suited to precast construction where bars may project at slight angles or where access for mechanical tightening is restricted.

Kridhan Infratech's Grout Couplers are manufactured to IS 16172 and ISO 15835 standards, ensuring full tensile and compressive strength transfer compliant with IS 456 and seismic zone requirements.

Where It's Used

Applications

Grout Couplers are the preferred splice solution wherever bars cannot be threaded or torqued.

01
Precast Column Splices

Connects precast column segments to cast-in-situ bases or to each other, ensuring full structural continuity.

02
Precast Wall Connections

Joins precast shear walls to floor slabs and foundations for moment-resisting and lateral-load connections.

03
Precast Beam-Column Joints

Provides a reliable moment connection between precast beams and columns without welding.

04
Foundation Dowels

Connects starter bars projecting from pile caps or raft foundations to precast column bases.

05
Tunnel Segment Connections

Used in tunnel lining segments where conventional mechanical couplers cannot be torqued in confined conditions.

06
Bridge Pier Splices

Enables fast, reliable rebar continuity at bridge pier construction joints in segmental bridge construction.
