Installation

Same one-piece elastomeric seal principle as FlexAtec 1000, with a ribbed rather than smooth surface for slip resistance and a narrower 25–75 mm gap range aimed at floor-to-floor-to-wall and wall-to-wall junctions. No aluminium frame to detail. Request CAD detail for the exact substrate fixing on your project.

Specification

A clause written to the FlexAtec 1200 data sheet

Worked for a 50 mm floor joint. Change the gap and the movement for each location on the joint schedule and leave the rest. It names what the joint must do rather than who makes it, so an alternative has to match the performance, not just the description.

Supply and install a ribbed elastomeric seal expansion joint system for floors and walls, to the locations scheduled, for a nominal structural gap of 50 mm, accommodating a movement of not less than ±15 mm. The system shall be cyclically tested to ASTM E-1399, Classes I and II, and the test evidence submitted. The seal surface shall be ribbed for slip resistance and remain accessible (ADA compliant) across the full movement cycle. It shall be rated by its data sheet for the scheduled traffic, per day: pedestrians more than 25,000, forklifts up to 10, cars more than 25,000. Where the joint crosses a fire compartment line, a fire barrier rated to the compartment is included (available on request; rating confirmed per job). Manufacture shall be against a site survey of the built gap taken after the structure is complete. The technical data sheet, the cross-section for each location and the installation method statement shall be submitted for approval before manufacture.

Each requirement is explained in how to specify an expansion joint. Writing to a CPWD tender? See the DSR items. See also expansion joints in buildings and the types of expansion joint.
