Description of project:

Coleman Rail’s main goal was to protect the bridge structure and its turn-ups

(ballast walls) against damage from the ballast and vibrations. They also wanted

to reduce structure-borne noise.

They were after a product that could be easy to install.

The other objective was to limit the impact force created when the trains enter

and exit the bridge structures (approaches). The 20mm Projex Damtec SBM with

it’s reinforced SBM tape was identified as the most appropriate solution for these

bridge structures.

The Projex reinforced SBM tape was used to join the SBM mats together to create

a smooth and even service and allow for a 90 degree turnup at the ballast blocks

without stressing the SBM.

 

From the dient:

Whilst the bridge was off the track the 20mm Projex Sub Ballast matting was laid

on to the bridge deck The matting was held down with adhesive and ballast

matting tape. Installation was easy as dimension meant cutting to size was not

necessary. Holes were cut for drainage. After the bridge was jacked in to position

Ballast was laid on top with wheeled/hi-rail excavators. Although concern was

raised about heavy machinery driving over the SBM the product held and did not

tear.
