Rebar Hook

Sigma rebar hooks allow easy single sided forming for large foundation pours  which greatly reduce the amount of tie length needed. Please notify appropriate parties that you will be hooking on to the reinforcing cage and proper precautions have been made to ensure structural integrity of the cage. Typically welded junctions around the rebar to be hooked or double tie wire is used to reinforce the rebar cage. Please consult your individual project engineer.

Water Stops

Sigma’s water stops are hydrophilic which means they swell and seal when they come into contact with water. A minimum of 3” cover should be used when using Sigma’s water stops to prevent concrete spalling. Sigma water stops are available for all sizes. This system is by far the easiest way to install water tight form ties in any waste water or water holding tank application.

EuroShe Coupler

Sigma Euro She Couplers are designed to be buried through the formwork in the concrete pour like a traditional she bolt. The length of the Euro Rod can be specified for a custom length she bolt tail. The length of the she bolt can be infinitely variable depending on the length of Sigma 700 Series which is needed to be spliced in. This is a great option for mass foundation pours as there is no need to patch and no worries about corrosion. This is also works exceedingly well combined with the rebar hook for mass foundation pours.

Euro Hex Coupler

Sigma Euro Hex Couplers are designed to accommodate 15mm Euro Rod Euro and couple to the Sigma 700 and 800 Series form ties. This coupler is designed to be used on the back side of the form, especially in radiused walls of water storage application to greatly reduce the scrap fiberglass tie that would be generated. This allows the fiberglass to still be used as the tie through the form, with a waterstop, to create a very inexpensive and water tight form tie.
