Stabiltrak 102

What is stabiltrak?

STABILTRAK 102 is a two-component polyurethane paste system with shortened bonding time dedicated to strengthening railroad embankment - i.e. to glue ballast, stabilize roadbed, join stony components and aggregates, both in a dry and slightly wet environment.

  • low viscosity
  • rigid-elastic work model
  • the possibility of application in humid conditions
  • short bonding time
  • the possibility of adjusting the time of hardening
  • good substratum penetration
  • low flammability


  • bonding railway ballast;
  • stabilization of the railway bed;
  • bonding of stone components and aggregates;
  • repair of the railway bed;


STABILTRAK 102 consists of two slightly viscous liquid components which mixed create polyurethane, characterizing low viscosity, well penetration of the base surface, possibility of regulation of hardening time and low flammability.

  • STABILTRAK 102 Component A is a mixture of poly- hydra compounds and supplementary ingredients. When there is a need it can be tinted to obtain required colour.
  • STABILTRAK 102 Component B is a derivative of diphenylmethane diisocyanate.

Components of the system are mixed with the usage of rams horn suction and forcing pump, static mixer and spraying with suitable angular lance on elements of a dry embankment. In contact with water (moisture) there may occur a reaction in which STABILTRAK 102 may spume a little till becoming hard elastic foam with closed pores. A thin layer of foam does not disturb in the process of bonding of broken stone. The components should have temperature form 6 to 30°C and the temperature of a base surface and irrigated material should not be lower than 6°C and higher than 45°C.

The process of application is demanding. Any works with STABLITRAK 102 must be done with protective clothes, gloves and glasses. Components of the system should not have any contact with skin. This is why the application of the product should be done by qualified COVER employees - only then the effect is safe and guaranteed.


  • metal canisters: component A - 30 kg , component B – 36 kg
  • steel barrels: component A - 205,5 kg , component B – 250 kg
  • other packages agreed with the recipient.

Safety of work:

All operations with the STABILTRAK 102 system should be performed in protective clothing, gloves and glasses. Avoid contact of system components with the body.


The product should be kept in 10 - 25°C in dry, ventilated rooms. Those requirements also concern transport.

Properly stored components of the system have 1 year durability.


As a result of exploitation of the railway structure, undesirable movement and slippage of the railway balustrade occurs. Most often it applies to places in transitional zones, between the embankment made of crushed stone and the rigid ground of engineering structures, for instance: in front of the bridges and viaducts, tracks crossing, at switches, in the vicinity of crossroads and especially on loaded tracks’ curves.

1. Stabilization of transitional areas near engineering facilities

Stabilization of the broken stone in places of transitional zones allows for elimination of rail bedding destabilization, caused by the threshold effect during the transit of the engineering objects. It has a significant influence on the reduction of the vibrations and deformability of the railway ballast layer.

2. Stabilization of railroad foundations in the arc load zone

As a result of the centrifugal force, during the rail movement, the loads on the curves are greater than in other places. The ballast stabilization service will secure the track foundations which are exposed to the movement.

3. Ballast protection during railroad infrastructure renovation

The technology provides stabilization of the ballast exposed to slipping as a result of renovations or repairs of neighbouring tracks with simultaneous rolling stock movement.

4. Stabilization of broken stone on junctions and intersections

Stabilization of broken stone in the vicinity of switches, crossings and track joints will effectively protect the aggregate against displacement and will significantly reduce operating costs.

5. Bonding of ballast, elimination of local damages

Local loosening of the ballast can be easily and quickly eliminated by opting for the service of ballast stabilization with binding resin. This will extend the durability of the structure.

6. Bonding of railroad ballast, elimination of "wild passages"

Prevents the so-called "wild passages" from the laxation of stone caused by mass, uncontrolled movement of pedestrians in unauthorized places.


  • strengthening places under crossovers and track crossings,
  • protection against the scrambling of individual stones during the high speed journeys,
  • protection of evacuation and emergency routes at railroad tracks and tunnels,
  • protection against vandalism,
  • elimination of loose spots in the ballast while maintaining continuity in train journeys,
  • easy cleaning next to platforms, stops and stations,
  • the ability to carry out renovation works while maintaining the continuity of passage on the adjacent track,
  • reduction of the need for frequent ballast maintenance,
  • extending the lifetime of the railway / tram line,
  • high comfort of traveling during fast speeds.
