Heathrow Airport Terminal 5

Heathrow Airport Terminal 5

Heathrow Airport is the busiest international airport in the United Kingdom, located around 25km west of central London.

Dextra has been involved in the construction of Terminal 5 and associated structures.

For Heathrow Airport, Dextra delivered its most advanced rebar splicing solution: Griptec, which is distributed in the United Kingdom by local expert fabricators.

As a result of its high performance, inherent reliability, systematic proof loading of every connection in factory conditions and comprehensive certification, Griptec is specified by major consultants globally. In the United Kingdom Griptec holds all three of the CARES splicing product certificates. That is TA1-A, TA1-B and TA1-C.

For our distributors, servicing the rebar preparation, the Griptec solution is convenient and productive. It is supported by a smart machine, manned by a single operator, offers highly productive cycle times (around 45 sec per rebar prepared) and includes of a test that systematically proof loads each and every bar / sleeve connection.

On the contractor side, Griptec offered a simple, effective and reliable way to connect rebar in columns, diaphragm wall and slabs. One application at Heathrow was for the roof of the new underground station. Griptec connections were also used to provide temporary openings that allowed men and equipment to freely move through the rebar structure and be easily ‘closed’ using single lengths of rebar with Griptec connections to both ends.

Thanks to its parallel-thread technology, Griptec does not require any torque wrenching at a specific value and can be verified by simple visual inspection, a significant advantage to simplify the project schedule and keep operations as productive as possible.
