IntroductionGroutec is a mechanical splicing system with one threaded end designed for the connection of pre-cast concrete elements. Groutec splice comply with Eurocode 2, BS8110, ISO 15835, ACI 318 type 2, and AASHTO code requirements. Metric ribbed reinforcing bars of grades up to 600 MPa and ASTM deformed reinforcing bars of grades up to 80 ksi can be spliced with Groutec.

Splicing is usually done in two steps: the Groutec coupler is first screwed onto the reinforcement prepared at the precast factory, installed flush with the formwork, after which the element is concreted.

Groutec couplers have been designed to work with grouts commonly-available on the market place. Grouts must be non-shrink types, with a minimum compressive strength of 65 MPa.

Two alternative models are available. Groutec L has a wide body allowing for more tolerance for the connection of two precast elements.

Groutec S (slim body) can be used in compact applications such as slim panels or narrow columns.

Groutec has been tested with grouts from major manufacturers such as Sika, Parex-Davco, Fosroc and BASF, which have a worldwide distribution network. However, attention is raised to the fact that such cement-based products are often produced locally from local raw materials, and that their properties vary depending not only on their origin, but also on climate conditions.

For first-time users, we strongly recommend that prior tests be carried in order to confirm the suitability of the selected grout.

Email us at [email protected] for any assistance.

The connection is then completed at the construction site, where the precast element is positioned next to the adjacent element so that its protruding bars enter the cavities inside the Groutec couplers. The cavities are then filled with grout, either by gravity or by means of a grouting pump.

Coupler dimensions

For one rebar diameter, different thread sizes are possible depending on whether BARTEC/FORTEC or ROLLTEC is used. It is threfore necessary to indicate the rebar diameter together with the system used to thread it (BARTEC / FORTEC or ROLLTEC).

Groutec is available in two versions:• Groutec L, which allows for larger misalignment tolerances thanks to a wide cavity.• Groutec S, which accomodates slim panels and narrow columns thanks a more compact design.

For both L and S models and all rebar diameters, the inlet & outlet holes are designed to fit with PE pipes (PE80/PN12.5) as per ISO 4427-2 and BS EN12201-2:2003 standards.

Rolltec Thread - Standard Splice

Table 12: Dimensions of Rolltec thread Standard Slices for Groutec L & S.


Transition splicing

Protruding length (P2) = E2 + (M) Sealing mortar height Protruding length (P3) = E3 + (M) Sealing mortar height

Protruding length (P1) = E1 + (M) Sealing mortar height Protruding length (P4) = E4 + (M) Sealing mortar height

Rebar length after threading (Lc1) = h2 + P1 - L2 + T2 Rebar length after threading (Lc3) = h3 + P4 - L3 + T3

Note: The above calculations assume that the sealing mortar height (M) is the same between each concrete element.-

This is the case when the bar inserted in the cavity is of a diameter different from the one on the threaded side.Connection of precast members reinforced with bars of different diameters can be made in two options :

1) Small diameter rebar threaded connection and large diameter rebar grouted connection.

2) Large diameter rebar threaded connection and small diameter rebar grouted connection.

If multiple concrete elements are assembled, embedment lengths may vary: E1 ≠ E2. Extra care should be taken in the design to ensure thedimensions of the correct coupler are taken into account.

This is the case when the bar inserted in the cavity is of a diameter different from the one on the threaded side.Connection of precast members reinforced with bars of different diameters can be made in two options :

1) Small diameter rebar threaded connection and large diameter rebar grouted connection.

2) Large diameter rebar threaded connection and small diameter rebar grouted connection.

If multiple concrete elements are assembled, embedment lengths may vary: E1 ≠ E2. Extra care should be taken in the design to ensure thedimensions of the correct coupler are taken into account.

Large diameter rebar threaded connection and small diameter rebar grouted connection / Gravity grouting.

Table 16: Dimensions of Large diameter rebar threaded connection and small diameter rebar grouted connection (Gravity gouting) for Groutec S.


A. Connect the coupler to the bar

1. Check from the coupler marking that the coupler (#1) corresponds to the bar size.

2. Remove the Thread Protection Cap from the threaded bar (if any) and the Coupler Protection Cap (#5, if any).

3. Inspect the threads of both the bar end and the coupler (#1). Clean any rust or dirt with a wire brush. Make sure that the provider of bars has made their threads in compliance with the ‘Type A’ tolerances from Dextra’s Bar-end preparation Quality Manual.

4. Screw the coupler (#1) onto the threaded bar until until snug fit. Check with a measure ruler that the depth of the coupler cavity is not less than the value Emin specified at pages 8 & 9.

B1. If no positioner is used1. If no positioner is used, make sure that the

Dust Protection Cap (#4) is present and tight. Position coupler flush with formwork.

2. Rotate coupler so that holes face the right direction. Tightly lock coupler together with the reinforcement by the use of wires.

B2. If formwork can be drilled3. Install the screw type positioner (#11)

through the formwork at the correct location. Rotate coupler so that holes face the right direction.

4. Then fit the coupler and bar onto the positionner (#11).

5. Finally tighten the positioner by the use of the locknut (#11) to firmly lock the assembly.

B3. If steel formwork is used1. Lock the magnetic type positioner (#12)

inside the coupler (#1) first, 2. Pre-position coupler and bar onto the

formwork at the correct position, rotate accordingly so that holes face the right direction.

3. Tightly lock coupler together with the reinforcement by the use of wires.

C. Install the inlet and outlet pipes

If the couplers are intended to be filled by gravity pouring, skip this part.

1. For each coupler, make sure that the inlet and outlet pipes have the proper length to reach the internal face of the formwork at the desired location.

2. Remove the plugs (#2, #3) and insert the pipes into the coupler holes. A mallet may be used to facilitate insertion. At this stage, it should not be possible to remove the pipes by hand anymore.

3. Check that there is no gap between the pipes and their holes. Use any kind of sealant or glue to close any gap.

4. Close the opposite end of both pipes with inlet/outlet pipe plug (#6, #7) or adhesive tape.

5. Check that the pipe plugs (#6, #7) are tight enough so that they won’t fall off during handling.

D. Casting of the concrete element

1. Close the formwork.2. Check that the couplers (#1) are tightly fixed, so that vibration won’t

cause them to move.3. Check that the couplers (#1) are orthogonal to the formwork and that

no thread is visible between the coupler and the bar.4. Check that the inlet and outlet pipes are facing the direction that

is intended for their grout injection, that they are tightly fixed so that vibration won’t cause them to move, and that there is no gap between them and the coupler that could allow cement paste to penetrate into the coupler.

5. Check that the Dust Proteciton Cap (#5) (or the Groutec positioner, #11 or #12) and the pipe plugs (#6, #7) are flush with the formwork, and that they are tight enough to prevent cement paste penetrating into the coupler.

6. Mark the location of all couplers (#1) and their inlet and outlet pipes on the external face of the formwork.

7. Check the length of reinforcing bar that emerges from the formwork on the opposite side (taking into account the thickness of the formwork). Make sure it is within the minimum embedment length and maximum protrusion length specified on page 5.

8. Pour the concrete, making sure not to displace any pipes.v

E. Formwork removal & inspection

1. Once the concrete is cured, remove the formwork and locate all couplers (#1).

2. Remove the Dust Protection Cap (#5), positioners (#11, #12) and pipe plugs (#8, #9) and check that no cement paste has penetrated.

3. Immediately clean any unwanted material by water. 4. After inspection, seal with grouting plugs (#8, #9).

4. Grout consumption

These figures of grout consumption are theoretical computations of the cavity inside the coupler.

For practical purpose they could be increased 15% in order to take into account :

1. The volume used in the inlet and outlet pipes.2. The volume used to join the two precast

elements.3. The volume that stays in the mixing tool.4. The volume that stays in the injection tool.5. Any other wastage.6. The effect of climatic conditions (Ambient

temperature, relative humidity, etc)7. The actual bar embedment length.

5. Grout recommendation

Dextra Groutec coupler can be used with standard non-shrink grouts meeting the following minimum specifications:

- Compressive strength : ≥ 65 MPa after 28 days as per ASTM C109 (50 mm cube)- Flowability: high flowability - Shrinkage: non-shrinking- Setting time ≥ 30 min

Note: Please contact your local Dextra representative to verify the performance of the selected grout.


6. Grouting process

A. Mixing

1. Make sure to strictly follow the work instructions provided by the grout manufacturer in the product datasheet and printed on the bag. Particularly, do not exceed the recommended water content. Always start with the median value of water content specified by the manufacturer.

2. Check the manufacturing expiry date of grouts before use. Do not use bags that are past their expiry date.

3. Do not use bags that have previously been opened or damaged. 4. Use mixers with a speed of not over 500 rpm to avoid the creation of

air bubbles inside the grout.5. In parallel, prepare the cube specimens (around 6 - 12 at a time) and

record the details such as date of preparation, testing date, batch no. of cement grout, water ratio, name or number of building, etc.

B. Grouting

1. Remove all residues from inside the coupler by water or air. In case you use water ensure that the couplers are dry before you start grouting .

2. Inject the cement grout by pump through the inlet hole.3. If the cement grout flows out from the outlet hole, then the inside of

the coupler is completely filled. 4. Tightly close the outlet hole with a pipe plug. Then inject more grout

during approx. 3 seconds. After that remove the injection valve and quickly close the inlet hole.

C. Bracing

1. You must install the bracing equipment before grouting.2. The fixing of the bracing equipment must be completed before the

grouted cement has hardened.3. You can remove the bracing equipment after grout strength has

been reached >30 MPa. The grout strength can be confirmed by tests on the grout sample specimens.

Topic Method Picture

1/ Inlet and/or Outlet port(s) do not reach the surface.

1. Check and mark the position of the ports according to the drawings.

2. Chip out the concrete at the marked positions to find the embedded ports.

3. Blow out the ports with air compressors or water and confirm that there is a clear passage from the inlet to outlet port.

2/ Due to dirt on the protruding rebar, the sealing disc gets stuck, slides into the coupler and reduces the gap of inlet port.

1. Try to clear the Inlet port by inserting a steel rod into it.

2. Follow step 3 of item 1.

3/ The sealing disc was forgotten, and the bedding mortar from the joint clogs the Inlet port.

1. Try to clear the Inlet port by inserting a steel rod into it.

2. Follow step 3 of item 1.

6/ Clogging has occurred inside the coupler.

1. Clean the inside with high pressure water.

2. After confirm a clear passage by blowing air through the ports, start re-grouting at about half the speed of normal operation.

7/ Protruding rebar is too close to the inlet and/or outlet port(s), restricting grout flow.

Insert e.g. a steel rod into the inlet or outlet port(s) and strike with sledge hammer to bend the rebar away from the ports and reduce restriction.

4/ Inlet and/or Outlet port(s) are clogged.

Due to debris etc.: Insert a steel rod into the port and hammer it to clean the port.

Due to plugs:

1. Use a hooked rod to scrape plugs out of the ports.

2. Repeat step 3 of item 1.

5/ Leakage during pumping of grout through the joint due to incomplete grouting of the joint.

1. Seal the joint with polyurethane, mortar, etc.

2. Clean the inside of coupler with water. (Preferably high pressure).

3. Confirm a clear passage by blowing air through the ports.

4. Re-grout.
