Installation Instructions for Detectable Warning Mat - Inset Model
The inset model
(IDW2x2) is designed to be installed into wet concrete. Each mat is 2'x2' square
and 1/4" thick (nominal). The mat has 9 molded in anchors with 1/4-20 thread. 9
1/4-20 x 1" stainless steel screws are supplied with each mat to attach to the
anchors and will secure the mat to the wet concrete.
We recommend purchasing a reverse pattern handheld installation tool
(IDWIT) from Road Kare International to simplify accurate and uniform
placement of inset mat (see photos below.

IDENTIFY INSTALLATION LOCATION ADA
inset mats must be set into position on wet concrete as soon as surface finishing has taken place.
INSTALL THE ADA INSET MAT Fasten
the nine
supplied 1/4-20 x 1" long stainless steel pan-head screws into the
molded-in anchors located in each mat. Lay the inset mat with fasteners
facing the concrete onto the surface of wet concrete. Using the
installation tool, match up the truncated domes on the ADA inset mat
with the reverse dome pattern on the installation tool. Apply even
pressure with the tool using a side to side motion to push the mat into
the wet concrete until the top of the mat is approximately 1/16"
from concrete surface (see photo below). Wipe off any concrete residue
from inset mat before it can dry on mat. Protect site and allow
concrete to cure.
