Projex Damtec Sub Ballast Matting (SBM) and STRAILastic provide Engineering, Protection & Isolation Rail Solutions for Heavy (Passenger) Rail, Heavy Haul Rail, Light Rail, Subways, Viaducts & Structures, High Speed Lines and Rapid Transit Networks

The Projex Damtec® Sub Ballast Mat (SBM) and the STRAILastic systems are one of the soundest investments you’ll ever make.

Choose from two of the very best sound and vibration railway control solutions

Sub Ballast Mat

The Projex Damtec Sub-Ballast Matting (SBM) is an isolation and protection mat for all types of railway construction & infrastructure maintenance in heavy rail, heavy haul rail, high speed, rapid transit and light rail networks / systems.

The Sub Ballast Mat (SBM) absorbs vibrations and considerably reduces acoustic emissions as well as structure borne sound transmissions.

It protects sub-grade formation and reduces frequency of the ballast maintenance requirement(s) through reduced vibration and better-balanced loading.

The Projex Damtec® Sub Ballast Mat is available in three different thicknesses to suit your requirements: 10mm, 15mm and 20mm.

Projex Damtec Sub Ballast Mat conforms to the ASA and TfNSW Standard for Ballast (T HR TR 00192 ST), Section 11.6. Track stiffness and ballast mat.

Why We Recommend These Products

Rail transport in Australia is a crucial aspect of the transport network. It consists of various track gauges and operates across urban and regional vast areas.

There is an invariable wear and tear performance of the rail infrastructure assets and equipment, which is consolidated by the harsh terrain(s), axle loads, operational specifications and urbanisation requirements or needs.

The installation of the Projex Damtec Sub-Ballast Mat (SBM) improves operational performance and allows reduction of the peak pressure in the ballast, to increase the stability of the track geometry, to effectively reduce the structure-borne sound and static vibrations.

Equally, the STRAILastic product range minimises noise emissions and dampens ground-borne and lateral vibrations from train operations, especially in low rail curves.

At Projex Group, our rail products are designed and manufactured to the highest quality and engineering standards, ensuring that we add value to our clients projects in all aspects of the project management cycle.

In servicing the rail industry we ensure the provision of our rail products and services of a gentle track for the highest demands.

All Projex Group railway products have been tested & certified to the industry standards, which ensure the highest efficiency of the product range.

These products are designed to offer optimum solutions to meet individual customer requirements. They are durable, high performing, cost effective, environmentally compliant and easy to install.
