Graffiti vandalism is costing the UK over £1 billion per year just to remove it.

The railway industry in particular is prone to graffiti vandalism with knock on effects to train services and fare paying customers.

Trespassing onto railway lines is potentially fatal.

Blocksil has a family of very thin film nano particle sized coatings that repel graffiti.

Within the coating family is a system for buildings that is self-cleaning.

The coating family is easy to apply and can be done so on site, thereby making the coatings much more useful to the client.

Energy consumption is increasing faster than population growth.

As more developing countries seek to improve their standard of living, so more energy will be consumed.

Increased energy consumption increases the levels of Carbon Dioxide emitted into the atmosphere, thereby adding to the greenhouse effect.
