J&P Building Systems / Jordahl® recommend the use of Pagel EH2 or Hilti CM 510-1 epoxy mortar. It is possible to use a different manufacturer and type of grout but users should satisfy themselves that the grout to be used gives the same performance as the recommended types. The grout manufacturer’s recommendations must be followed.

Further Consultation Required

If the channel is exposed more than 2/3 depth, or there are visible voids below or around the channel then is will be necessary to contact the channel supplier for further assistance on a location specific basis. Depending on the condition and load requirement they should confirm the suitability or otherwise of the channel and make appropriate recommendations.

Case 2

Description

Channels that have been installed and are sunken below the surface of the concrete will not suffer any direct performance penalties, however as there is an area of unsupported bolt shank it may introduce bending in the bolt that may not have been allowed for within the initial design.

Tee Bolts are able to accommodate a degree of bending moment and this information will be available in the supplier’s catalogue.

Acceptable Limits

Provided that the gap between the top of the channel lips and the underside of the bracket is no more than 5mm, the channel and bolts will remain able to take the full load without any need for remedial work.
