Our client Scarab Sweepers approached us complaining that a build-up of paint and dust on their spray booth  floors had not only become unsightly but was also causing potential hazards amongst their workers.

We were approached to see if we could come up with a solution to rectify this problem with our hydroblaster.

Hydroblasting technology is the most environmentally friendly method of Line Removal, Re-texturing Asphalt and Cleansing surfaces. Our hydroblast units use clean water without additives at ultra-high pressure of up to 40,000 PSI to deep clean surfaces. Different heads are used dependent on the requirement; for instance cleansing, removal, demolition etc.


Within a couple of hours, the surface had been rejuvenated and brought back to its near original condition.

The client and Facilities Manager, Mr. Page was impressed with the speed of delivery and the quality of work, commenting ‘I just wanted to say thank you for the great job your guys did on Saturday cleaning and removing the build-up of paint on our booth floors’.

We were approached by our client to install a pedestrian walkway that would circumnavigate the perimeter of Euston train station.

Upon visit, one of our engineers noted that the flow of work vehicle traffic greatly increased and decreased in particular areas around the site.

With this in mind, we suggested that it would be practical to incorporate colour coordinated walkways as a means of notifying the workers of the change in risk level in each area.

To coincide with the walkways, we had signage designed and installed with the purpose of informing pedestrians when they were entering a new zone and what this meant.

We also had a toolbox talk drafted to accompany the signs, so that the workers would understand the Health & Safety requirements connected to the signs and walkways.

TP Paddington depot is one of the most highly trafficked depots across the entire property portfolio, and past lining works had completely worn out well ahead of expected life.

Paddington Depot

Travis Perkins Plc.


As official contractor for all Travis Perkins depots in London, Home Counties, South East and South we hydro blast and line many TP depots.

The Paddington depot is one of the most highly trafficked across all Travis Perkins sites. Large articulated vehicles and heavy machinery operate here constantly and as a result lines and markings were often well worn, unclear or non-existent. We advised that thermoplastic paint was also not suitable in this environment, as it would need regular refreshing, which caused line thickness to build up and in turn create a trip hazard. Travis Perkins yards are predominantly concrete which is not ideal for thermoplastic as it can crack and chip in cold weather.


To tackle this problem we worked closely with Travis Perkins for over a year carrying out examinations and field trials of different products and application methods. Eventually we developed a bespoke solution that suits Travis Perkins needs and eradicated the previous issues.

The new method and solution now:

  • Can be easily cleansed by hosing off
  • Resist wear better than thermoplastic (previous solution used)
  • Provides a safer environment by preventing trip hazards
  • Is more economical as markings don’t have to be relayed as often

The new Top Gear team planned a stunt for Matt LeBlanc to carry out a race around London’s streets in a mad Ford Mustang car called the “Hoonigan”, pulling donuts in and around the top spots in London.

BBC Top Gear


In March 2016, Top Gear filmed a planned race through and around numerous top sights in central London as a means of showcasing a new Ford Mustang nicknamed ‘The Hoonigan’. The footage showed the car performing stunts outside of the Houses of Parliament, Tower of London, St. Pauls Cathedral, Whitehall and Canary Wharf.

The BBC approached THB to take up any rubber and tyre marks left on the road by cars. The hydroblaster was provided with a police motorcycle escort throughout the clean up ensuring ultimate safety. This was done using hydro blasting technology, which cleanses the tarmac through ultra high-pressured water and removed any remnants.

Hydroblasting is the most environmentally friendly method of line removal, re-texturing asphalt and cleaning surfaces. Our hydroblaster uses clean water devoid of any additives at ultra high pressure to deep clean surfaces. We offer our services 27/4 to ensure that we can meet your individual requirements.

Our hydroblasters operate at Ultra High Pressure of up to 40,000 PSI (2700 Bar), and the various different heads that we carry makes them the perfect tool for all applications. It creates minimal disruption to surfaces unlike other removal methods that can cause permanent damage.

Unlike other cleaning methods, our hydroblasters collect all of the dirt and debris into an onboard tank for, ensuring no illegal run off into surface drains. All waste is then disposed off in compliance with Environment agency and our Waste Carriers License.

The client was happy with the end results as the hydro blaster managed to take up all rubber and oil effectively and efficiently, with minimal disruption to London roads.

As part of the Brixton Design Trail Eley Kishimoto has designed four colourful flash crossings to replace the existing crossings outside the Dogstar at the junction of Atlantic, Railton and Coldharbour.

Top Secret


As part of The London Design Festival, artists Camille Walala and Eley Kishimoto designed colourful pedestrian crossings in a bid to reimagine the everyday experience of crossing a road. Brixton crossings were required outside the Dogstar at the junction of Atlantic, Railton and Coldharbour funded by Brixton BID. The Southwark street pedestrian crossing was commissioned by Better Bankside and Transport for London. As well as being cultural hotspots, the areas also have a high volume of cars, cyclists and pedestrians; often making them precarious places to navigate.

THB were approached to see what methods and products would work as a pedestrian crossing and with potential designs.


In lieu of the clients needs, it became clear that the most effective solution would be using a preformed bespoke material.

The reasoning behind this being:

  • The designs were intricate and would have been harder to replicate by hand/ increased risk of error
  • The application time was a lot quicker than other methods and therefore caused less disruption to traffic
  • It is a cost effective alternative to other solutions and provided a more professional finish.

Our objective was to create a series of crossings using a preformed bespoke material in a short period of time.

Key Stats










We successfully installed 5 crossings over two nights creating crossings that:

  • Transformed everyday infrastructure
  • Enhanced road safety & visibility
  • Became talking point and made BBC News

We can help you to design, create and implement any manner of preformed marking. Common subjects include: Company logos, Parking bay symbols, speed roundels and many other road signs.

The Result

All the Travis Perkins depots have been encountering the same issues with Thermoplastic for many years. Due to the nature of their business, their yards are highly trafficked by large lorries and forklift trucks.

Travis Perkins have been experiencing serious and costly issues with Thermoplastic Line Markings in all of their yards for a number of years. Their yards are heavily trafficked by large articulated and heavy trucks and forklifts and used to stack pallets and building materials that are often dragged or pushed around meaning that markings quickly become dirty and lose visibility.

We advised that Thermoplastic markings are not ideal in such situations, as constantly refreshing these markings causes the line thickness to build up into a trip hazard, and as most of their yards are predominantly concrete, thermoplastic can crack and chip away particularly after a spell of cold weather.

The Trials

To fully understand the issues they faced, we have worked with Travis Perkins for over a year carrying out examinations of sites and conducting field trials of carefully selected products and application methods.

By carrying out these trials and carefully monitoring performance and comparing data for each product over a period of time, we have developed bespoke solutions that suit Travis Perkins specific needs across their range of premises.

We are very proud to say that all our hard work and determination has paid off, and we are now the official contractor for all Travis Perkins depots in London, Home Counties, South East and South.


We have developed a select range of products and bespoke application methods that provide linings that:

  • Clean easily by hosing off
  • Resist wear better than Thermoplastics
  • Do not build up into trip hazards, helping our customer to keep their staff and visitor safe
  • Save our customer money by reducing the need to constantly re-mark

Our client approached us to lay some temporary markings for the Race of Champions. Their main priority was that the markings must be able to be washed away by water at the end of the event.

Olympic Stadium


Our client approached us with the task of laying temporary markings for an event called ‘Race for Champions’. This was a high profile event at the Olympic stadium where various motorsport disciplines competed for the title of “Worlds Greatest Driver”. The markings would be laid on a purpose built track within the stadium.

The main priority was that the markings would be resilient enough to withstand rainfall but could be taken off with a power washer once the event had finished.


In order to provide a solution that was rain resistant and washable we sourced a temporary graffiti paint that laid well and looked aesthetically pleasing.

Unfortunately heavy rain caused the paint to look streaky so we combined it with a sealant, which made it resistant to rain but removable by power washing.

The job was a success as the solution withstood all elements throughout the event and the clients were pleased with the outcome.

The apron of the airport had previously been painted by another contractor, which the client was unhappy with due to the poor quality of the work. Some of the lines were not straight and most of them had faded after only two months.

Top Secret



The client approached us requesting that all outstanding markings on the airfield would be taken up. This was due to wear and poor quality of work. They also wanted new markings to be administered with a solution that provided long-term wear and high visibility.

It was important to the client that all works had to be completed whilst the airport remained live and operational and during adverse weather conditions.


In response to this, we started by hydro blasting and taking up the pre existing markings. We then developed a bespoke three part time/airless spray/ seal system that provided optimum longevity whilst maintaining high visibility in wet conditions and at night. Due to its long effective life, the solution would also minimize future operational disruption and prove the most economical option.
