Projex Damtec Sub-Ballast Matting (SBM) ...
Projex Damtec Sub-Ballast Matting (SBM) for Rail
SBM is an isolation & 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 SBM mat 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.
Applications
- Ground Services
- Rail Bridges / Culverts
- Underpasses / tunnels
- Railway Stations
- Open Superstructures
- Environmentally sensitive areas
- Rail Crossings
- Plain rail tracks
- Heavy and Heavy Haul Rail Networks
- Light Rail systems
- Rapid transit systems
- Passing Loops
- Stabling and rolling stock maintenance facilities
- Viaducts
- Controls vibrations and noise emissions to buildings
Benefits
- German manufactured, superior performance
- Proven and tested technology
- Extremely cost effective
- Easy installation
- Environment – friendly
- Stock held in Australia
- Range of dynamic static stiffness applicable to different track requirements and applications
- Complies with quality, regulatory & engineering standards
- Manufactured from recycled rubber
- Extremely tough & durable
- High kinetic energy absorption
- Ideal for the insulation of acoustic & vibration emissions
Features
- Protects the sensitive sealing (waterproofing) layer against damage from ballast
- Reduces structure-borne noise? and secondary air-borne noise
- Protects adjacent buildings by reducing vibrations
- Prolongs the lifetime of the ballast
- Permeable to water
- Position and level of the track remain stable in long term
- High level of elasticity allowing for the absorption of undulations in the bedding layer
- Can be used for mass spring systems?- uncomplicated installation
- High degree of performance with axle loads in excess of 40 TAL

The Projex Damtec Sub-Ballast Matting is an isolation and protection mat that protects the sub-grade formation beneath the track. Its vibration-absorbing mat reduces acoustic emissions and structure-borne sound transmission, helping limit noise and vibration reaching nearby buildings. Rail bridge and tunnel projects use it to protect sensitive waterproofing layers from ballast damage during construction and maintenance.
- Projex SBM Joining Tape is required to connect rolls and complete the system
- High performance at axle loads above 40 TAL
- Dynamic and static stiffness options suit different track requirements
- Manufactured from recycled rubber
- Permeable to water
