Installation Procedure 

Be sure to read and understand all of these instructions before you begin. 

A. The physical characteristics of the concrete shall be as specified in the contract 

documents while maintaining a slump range of 4-7 inches to permit the solid 

placement of the ADA Cast-In-Place Replaceable Tactile Unit (ADAREP) in the 

wet cement. 

B. The concrete shall be poured and finished level, true and smooth to 

the required dimensions prior to the placement of the ADAREP unit. 

C. Place the ADAREP unit 6-8 inches from the curb line. Working in a 

grid pattern, tamp the ADAREP unit into the wet concrete using a rubber 

mallet and a piece of wood. Continue this process until all of the air has 

been released, and the ADAREP unit surface is flush with the surrounding area. 

IMPORTANT: Avoid striking the surface of the ADAREP unit directly. 

D. Following the placement, the ADAREP unit elevation should be checked to 

the adjacent surface with a straight edge. The ADAREP unit elevation should 

be consistent with the Contract Drawings and Specifications. Any required 

adjustments must be made prior to the time when the concrete begins to set. 

E. Important Notice to Installer: To allow for expansion and contraction, 

after tile is installed, use a 1/4” finish edge trowel around entire perimeter. On a continous 

run, be sure to space each unit 1/8” apart. 

F. When you are confident that the ADAREP unit is in place and no further adjustments 

are needed, place a cinder block on both ends to hold the ADAREP unit in 

place while the concrete sets. 

G. During and after the ADAREP unit installation, as well as the concrete curing 

stage, no walking or external forces can be placed on the ADAREP unit. The area 

must be protected from pedestrian traffic until concrete is cured. The ADAREP 

Warning Surface will be ready for pedestrian traffic within 2-4 hours. 

H. Be sure to remove plastic 

protective covering from the face 

of the ADAREP Unit once the 

concrete is cured. 

*Not recommended or warrantied for 

asphalt installation. 

Do not cut Cast-In-Place Replaceable Tactile. Use an appropriate 

sized tactile or Radius Tactile to fit the requirement. 

Contact manufacturer for more details.

Replacement Procedure 

Be sure to read and understand all of these 

instructions before you begin. 

A. Lift the existing composite bolt cap from each anchor location on the 

ADA Cast-In-Place Replaceable Tactile unit (ADAREP) with a flat head 

screw driver. 

B. Remove the existing 1/2” x 1½” stainless steel bolts from each anchor 

location on the ADAREP unit with a ratchet. Save & reuse. 

C. Tap around all sides of the ADAREP unit and across the middle with a 

rubber mallet, working in a grid pattern. 

D. Pry the existing ADAREP unit from the concrete ramp with a small 

prybar, working around the edges until it can be lifted cleanly away. 

E. Be sure to remove all small debris and dust from the existing impression 

in the concrete ramp. 

IMPORTANT: Be careful not to get debris into anchor locations. 

F. Replace new ADAREP unit, of same size and orientation, into impression 

in concrete ramp. Lightly tamp down the ADAREP unit with a rubber 

mallet and a piece of wood. Continue this process until the ADAREP unit 

is set firmly into existing impression in concrete ramp. 

IMPORTANT: Avoid striking the ADAREP unit directly. 

G. Bolt existing 1/2” x 1½” stainless steel bolts back into each anchor location 

on new ADAREP unit. 

H. Snap a new composite bolt cap provided, into each anchor location 

on the ADAREP unit. The ADAREP unit is ready for pedestrian 

traffic immediately after installation is complete.

A. The installation area should be cleaned of all debris, oil and grease, making 

sure the area is completely free of moisture. Tactile Panel may be surface 

mounted on existing pre-cleaned substrate. 

B. Lay out the Tactile Panel on the substrate as it will appear when installed. 

• If required, the Tactile Panel may be cut using a table saw and diamond 

tipped blade. 10’, 15’, & 20’ radius are pre-scored on backside of tactile 

panel. See web site for more details. 

C. Place a 3/8” bead of adhesive on the frame of the bottom of each Tactile 

Panel. Adhesive yield: 10SF per 10 ounce cartridge. 18-24SF per 20 ounce 

cartridge. 

D. Set the Tactile Panel in the installation area. Make all necessary adjustments 

prior to fastening. 

E. Fasteners shall be installed in pre-formed fastener locations. Holes shall be 

drilled using a hammer drill with 1/4” x 2” min SDS bits. The drilled holes 

must be a minimum of 2” deep. Place fasteners in hole and hammer into 

place. 

• If additional fasteners are required, use a 1/2”, six point, 82 degree 

countersink to add a new fastener location. Follow the same drilling 

method for installing the fastener. 

F. Caulk around perimeter of entire installation using BASF NP1 or 

equivalent. 

• All concrete dust present on the Tactile Panel resulting from the drilling 

process must be cleaned off of the Tactile Panel prior to using any 

caulking materials.

Cast-In-Place Tactile 



A. The physical characteristics of the concrete shall be as specified in the 

contract documents while maintaining a slump range of 4-7 to permit the solid 

placement of the Tactile Unit in the wet cement. 

B. The concrete shall be poured and finished level, true and smooth to the required 

dimensions prior to the placement of the Tactile Unit. 

C. Place the Tactile Unit 6-8 inches from the curb line. Working in a grid pattern, 

tamp the Tactile Unit into the wet concrete using a rubber mallet 

and a piece of wood. Continue this process until all of the air has been 

released, and the Tactile Unit surface is flush with the surrounding area. 

IMPORTANT: Avoid striking the surface of the Tactile Unit directly. 

D. Following the placement, the Tactile Unit elevation should be checked to the adjacent 

surface with a straight edge. The Tactile Unit elevation should be consistent 

with the contract drawings and specifications. Any required 

adjustments must be made prior to the time when the concrete 

begins to set. 

E. Important Notice to Installer: To allow for expansion 

and contraction, after tile is installed, use a 1/4” finish edge trowel 

around entire perimeter. On a continous run, be sure to space each 

unit 1/8” apart. 

F. When you are confident that the Tactile Unit is in place, and 

no further adjustments are needed, place a cinder block on both 

ends to hold the Tactile Unit in place while the concrete sets. 

G. During and after the Tactile Unit installation, as well as the 

concrete curing stage, no walking or external forces can be 

placed on the Tactile Unit. The area must be protected from 

pedestrian traffic until concrete is cured. The Tactile Warning 

Surface will be ready for pedestrian traffic within 2-4 hours. 

H. Be sure to remove plastic protective covering from the face of 

the Tactile Unit once the concrete is cured.

Accessible Public Rights-Of-Way (11/23/05) 

R304 Detectable Warning Surfaces 

R304.1 General. Detectable warnings shall consist of a surface of truncated domes aligned in a 

square or radial grid pattern and shall comply with R304. 

R304.1.1 Dome Size. Truncated domes in a detectable warning surface shall have a base 

diameter of 23 mm (0.9 in) minimum to 36 mm (1.4 in) maximum, a top diameter of 50 

percent of the base diameter minimum to 65 precent of the base diameter maximum, and a 

height of 5 mm (0.2 in). 

R304.1.2 Dome Spacing. Truncated domes in a detectable warning surface shall have a 

center-to-center spacing of 41 mm (1.6 in) minimum and 61 mm (2.4 in) maximum, and 

a base-to-base spacing of 17 mm (.65 in) minimum, measured between the most adjacent 

domes. 

R304.1.3 Contrast. Detectable warning surfaces shall contrast visually with adjacent gutter, 

street or highway, or walkway surface, either light-on-dark, or dark-on-light. 

R304.1.4 Size. Detectable warning surfaces shall extend 610 mm (24 in) minimum in the 

direction of travel and the full width of the curb ramp (exclusive of flares), the landing, or the 

blended transition. 

R304.2 Location and Alignment 

R304.2.1 Perpendicular Curb Ramps. Where both ends of the bottom grade break 

complying with R303.3.4 are 1.5 m (5.0 ft) or less from the back of the curb, the detectable 

warning shall be located on the ramp surface at the bottom grade break. Where either end of 

the bottom grade break is more than 1.5 m (5.0 ft) from the back of the curb, the 

detectable warning shall be located on the lower landing. 

R304.2.2 Landings and Blended Transitions. The detectable warning shall be located on 

the landing or blended transition at the back of the curb. 

R304.2.3 Alignment. The rows of truncated domes in a detectable warning surface shall be 

aligned to be perpendicular or radial to the grade break between the ramp, landing, or blended 

transition and the street.
