Selecting the right expansion board for an expansion joint
Selecting the right expansion board for an expansion joint
(OP)
Here is the situation, due to the project requirements I need an expansion board that is flexible and excellent as a water seal. The board would be used for an expansion joint between a concrete wall and a wall cap in order to prevent water from infiltrating behind the wall and freezing and thereby creating problems. Basically we need something better than typical wood/plastic expansion boards. Any suggestions?
Also what would be the procedure to install these? Would a sealant be also needed on top of the board to ensure a better seal?

The only place I have seen these used is in buildings, generally between an occupied building and a parking garage.

As a simple alternative, put in the typical fiberboard (asphalt impregnated jute) and after concrete placement, put a backer rod and sealant in the upper inch of the joint after removing part of the fiberboard.

Serendipity, just this minute ran across this site while looking for a mechanical coupler. They have a lot doodads for the concrete set.
