Railway infrastructures and roads tend to become prone to damage due to deterioration from constant heavy loads from trains, trucks, and trams.
Train Tracks can buckle from loss of support due to subsidence in its subgrade, leading to settlement and voids. This has potential to cause mechanical damage to trains and even lead to derailment.
Rail Infrastructure – Including railway platforms, train stations, terminals, train yards, level crossing, and bridges.
Some causes of subsidence are:
- Vibrations and constant loading/unloading of tracks from pedestrian trains to heavy haul transport trains.
- Weather/erosion from constant wetting/drying of railway subgrade/soil.
- Water seepage due to below ground infrastructure/railway stations.
These issues can compromise safety and cause major delays.
The advantages of railway stabilisation using polyurethane resin
- Fast – Railway track, platforms, buildings, weighbridges, and hard standing areas experiencing subsidence can all be treated more efficient and quicker than traditional underpinning methods. The resin method can be carried out in as little as a few hours.
- Minimum disruption –Each project we undertake has different arrangements. When working on the rail we need to ensure we reduce rail possession time, which is of course an important TPO consideration. In most cases, works will be carried out during the closing hours to prevent disruption of any running services.
- Efficient –With the use of a GPR (ground penetrating radar) we can work out an exact treatment area. Using laser levels also gives us the accuracy down to 0.05mm.
- Environment – Polyurethane is inherently more eco-friendly than most other plastics. It also doesn’t contain any chemicals that interfere with endocrine and hormone systems, nor does it contribute to PH change in soil or water.
- Cost – Most major infrastructure has asset management tools specifying structure lifespan and maintenance schedules. Our technology can improve structure lifespan and fit within maintenance schedules ensuring longer structure life of use. This prolongs the need to replace infrastructure which can be costly.
