The profile of the Corduroy Warning Surface comprises rounded bars running transversely across the direction of pedestrian travel. The bars are 6mm (± 0.5mm) high, 20mm wide and spaced 50mm from the centre of one bar to the centre of the next. Thickness 5mm.

Sizing: 400mm x 400mm

Colour: Buff, Grey & Charcoal – Request if any other specific colour is required.

Installing our surface mounted tactile paving can be done quickly and easily using our two-part moisture tolerant adhesive. Please see below.

Preparation

Surfaces will need to be brushed to remove loose materials and dust. Older sites may require the use of a jet-wash to ensure the surface is clean. Do not worry if he surface is damp as our two-part moisture tolerant adhesive can be applied in damp conditions.  

Setting Out Surface Mounted Tactile Paving 

Position the tactiles in the formation which is required and decide whether any tiles need to be cut to size. 

Cutting Surface Mounted Tactiles

1. After the tactiles have been placed in the required position, any cuts that need to be made should be marked with a marker or pencil. The detailed grid on the tactiles can be useful when marking straight lines. When cuts are skewed, use a straight edge as a guide. 
2. To cut tactiles an angle grinder or cut-off saw fit with a diamond blade should be used. A standard abrasive blade has the potential to be damaged due to the contents and toughened resin components of the tactile.
3. Place the tactile onto a board or piece of timber and ensure this is held securely, whilst the operator follows the marked line, slicing the tactile to the required size.

Masking Off The Perimeter 

1. Mask off the perimeter of the area to ensure the resin adhesive does not spread to the non-tactile surface. We advise the tape be laid in 600mm strips, which helps to ensure the line is kept straight. Ensure the entire perimeter is marked with tape to prevent the adhesive from spreading past the area.
2. Once masking is complete, tactiles are removed so the area is clear. The tape is checked to ensure there are no loose ends and it is firmly in place.

Mixing The Two-Part Adhesive 

Our adhesive is a two-part moisture tolerant resin system, which comes in pre-batched quantities sufficient to cover at least 1.6m2. Part A is the base resin and part B is the activator resin.

1. The activator is poured into the pail containing the base resin, ensure you stir evenly and thoroughly for approximately 3 minutes.

The working life of the mix is around 20-30 minutes on sunny days and longer on colder days. Accordingly, the mix should not be mixed until 5 minutes or so before it is used.

Laying The Surface Mounted Tactiles 

1. The adhesive mix is poured directly from the pail to the substrate and it spread over evenly with a notched trowel. Only enough adhesive is poured for the area of two tactiles at any one time to ensure the operative does not have to overstretch.

2. Once an area is covered with adhesive, tactiles are lowered onto the adhesive and are pressed down lightly. The flexibility of the tactiles allows them to be rolled into place, excluding any air pockets in the process. Place the tactile carefully, as it is bad practice to re-lift the tactiles after placement which will weaken the bond. If you do need to move a tactile, it is best to lay down fresh adhesive beforehand.
