Latest insights into the most effective and safest use of water jetting on construction sites will be a strong focus at WJA Trade Show 2025, the UK’s only exhibition dedicated to the water jetting industry.
Given the many advantages of water jetting and the risk factors associated with its use, construction, civil engineering, and health and safety professionals are being encouraged to attend the event.
The exhibition – which is free to attend – is being held at StoneX Stadium, home of the Saracens Premiership rugby club, in North London, on Thursday 11th September.
Water jetting innovation
“WJA Trade Show 2025 is the ideal opportunity for construction professionals to be updated on all aspects of water jetting application and safety.
“Multiple contractors and equipment suppliers who support the construction industry, many of them WJA members and others from overseas, will be exhibiting their latest products and services.
“Innovations in water jetting, many used in construction, are coming though at pace. By attending WJA Trade Show 2025, visitors will see and hear about all these exciting developments in one place.”
– Lee O’Callaghan, Chairman of the Water Jetting Association
Water jetting has become a standard tool on construction sites, through its use for hydrodemolition of concrete structures, cutting of concrete and steel, surface preparation and pressure washing of buildings, roadways and parking areas.
WJA Trade Show 2025 will have two external exhibition areas displaying a range of large equipment and vehicles often used on construction sites.
They include hydrodemolition robots showcased by Aquajet UK. The machines are used to remove concrete from a wide range of structures, including bridges, roads, carparks, building foundations and dock piers.

Concrete cutting technology
Drainage vehicle manufacturers Bucher Municipal, ROM, and Rioned will display new compact jet vac tankers. Their smaller size makes them better able to clean drains, sewers, culverts and ducting on congested sites.
Exhibitor AQ-Rent will be displaying its latest KOKS vacuumation tanker – technology that is increasingly used to safely and quickly remove dry and wet materials on construction sites, especially around utility assets.
Abrasive cutting specialist RGL Services will be exhibiting technology that makes modifying concrete and steel structures easier, safer and more sustainable, whether on conventional building sites or in the middle of the North Sea, working on off-shore windfarms.
Exhibitor Calder, will be showing the latest in UHP abrasive cutting equipment ideal for civil engineering and construction applications.
Focus on jetting safety
TST Sweden, a global leader in water jetting PPE and site safety systems, will be contributing to an expert speaker’s programme, sharing latest evidence and thinking on environment protection systems on worksites.
WJA Director Leanne Smith said: “The WJA’s technical team will talk about our three codes of practice for water jetting – for high and ultra-high pressure jetting, drain and sewer jetting, and pressure washing.
“We’ll have information about the accredited training the WJA offers across all forms of water jetting. Visitors can leave fully-informed about how to ensure water jetting carried out on their worksites is safe and compliant.”
