A replaceable (wet-set) composite is a detectable warning system that, as the name suggests, can be replaced. After initial installation, all you have to do is unbolt the surface of the old unit and replace it with a new surface. Here is a guide to replaceable (wet-set) composite installation:
- Submittals: The first step to installing replaceable composite is to have all specifications approved by an engineer. This will help prevent future complications while guaranteeing compliance with regulations outlined by the ADA.
- Truncated Dome Alignment: If you are installing successive replaceable composite sheets, be sure to check whether the truncated domes on the sheets are aligned. This will help ensure that the detectable warning system is effective and safe.
- Concrete Substrate: Replaceable composite sheets work best when they are installed in stiffer concrete. Wet concrete mixes can increase maintenance charges and make it more difficult to install the sheets properly.
- Installation: The units themselves are installed and fitted with the help of a rubber mallet. Alternatively, you can vibrate the units into the concrete in order to ensure that there are no air pockets.
- Profile Leveling: When you use successive replaceable composite sheets, there is always the chance that one might be slightly elevated relative to the others. This can impede the unit’s functionality and safety. In order to rectify this issue, place a piece of plywood to span the joint line between the two successive composite sheets.
- Spacing: It is of the utmost importance that successive composite sheets are separated by a 1/8-inch gap.
