Customer reported Rejuvo using a Kersten UBS weed brush for footpath preparation
Contractor Surface preparation

Rejuvo footpath preparation

Rejuvo needed clean, solid path edges before applying footway repair systems across projects around the country.

Reported productivity 500 to 1,000 metres of heavily soiled footpath per day with one operator
Challenge
Hand tools and pressure washing were slower and could cause more surface damage.
Approach
UBS weed brush removes encroached soil and vegetation before resurfacing.
Outcome
Rejuvo developed a small fleet of Kersten machines for projects nationwide.
Programme evidence Hull Love Your Neighbourhood street clean-up using Kersten machinery
Local authority Neighbourhood cleansing

Hull Love Your Neighbourhood

Challenge
Improve access, appearance and surface condition across neighbourhood streets.
Approach
UBS power units and weed brushes within a multi-service clean-up programme.
Context
The street totals describe the wider council programme, not machine output alone.
Programme evidence Mechanical weed-management equipment used in the Edinburgh programme
Local authority Pesticide reduction

Edinburgh expands mechanical weeding

The council linked weed management more closely with street care, proactive cleaning and community engagement.

Programme direction Green spaces moved away from spraying, with wider glyphosate phase-out targeted
Challenge
Reduce reliance on glyphosate across council-managed assets.
Approach
Expand mechanical weeding and sweeping, supported by planned street-cleaning regimes.
Learning
Responsibility, data, cleansing and community involvement all form part of the transition.
Customer reported Kersten de-moss sweeper shown in the Newport prevention article
Local authority Prevention

Newport preventative maintenance

Winter weed brushing was used to limit soil build-up before the main spring growing period.

Reported outcome Fewer spring weeds and a large reduction in glyphosate use
Challenge
Reduce the seedbed and weed burden before growth accelerates.
Approach
Use weed brushes preventatively during winter to minimise soil accumulation.
Evidence
Outcome reported by Newport Council during an industry meeting.
Contractor Integrated methods

Cormac puts IWM into practice

Operational learning Mechanical sweeping for routine hard surfaces, with targeted thermal treatment where appropriate
Challenge
Respond to stakeholder demand for lower chemical dependency.
Approach
Trial several methods and match each one to terrain, frequency and operational need.
Learning
A blended programme was more practical than relying on one universal treatment.

Customer reported New Forest District Council vehicle fitted with a Lehner Polaro spreader
District council Winter service

New Forest District Council winter gritting

Two pickup-mounted Lehner Polaro spreaders replaced pedestrian spreading across a large and geographically dispersed council car-park network.

Reported operational result Two operatives completed 54 car parks in three hours, with salt use reduced from 40 to 45 bags to 10 to 15 bags per day
Before
Four teams of two took all day and mainly treated entrances and corners.
After
Two operatives treated complete car parks before opening time.
Payback
The council team believed the spreaders paid for themselves during the first season.
Measured treatment trial Crassula helmsii growing densely beside a waterbody in the Bristol Water treatment case study
Water utility Hot-water treatment

Bristol Water Crassula treatment trial

A small field trial compared electric, hot-air and hot-water treatment on dense Crassula helmsii growing around a waterbody.

Treatment comparison Hot water was the clear winner, penetrating the layered growth and leading to an Eco Weedkiller Pro20 order
Challenge
Control invasive Crassula beside and within a water environment where chemical treatment was not suitable.
Approach
Compare Zasso electric treatment, Ripagreen hot air and 100°C low-pressure hot water.
Outcome

Frequently Asked Questions

The library categorizes stories to distinguish between different types of evidence. These include "Measured trials" which provide quantified field outcomes from defined trials, "Customer reported" for operational experiences like productivity and usability, "Programme evidence" showing equipment within broader council or contractor programmes, and "Application examples" demonstrating practical machine and task fit. This helps users understand the context and rigor of each presented result.

Kersten equipment has demonstrated significant results across various applications. For instance, a Bracknell trial showed a 49% reduction in active substance use for weed management. Veolia estimated an 81-mile machine payback for path edging with the UBS 16. Additionally, Rejuvo reported clearing 500 to 1,000 meters of heavily soiled footpath per day with one operator using a Kersten UBS weed brush for surface preparation.

You can search the evidence library by filtering through various criteria. This includes filtering by application type such as weed management, path maintenance, sweeping, or winter service. You can also search for a specific customer, surface type, machine, desired outcome, or sector, allowing you to quickly locate projects that match your particular requirements and operational context.

To plan a trial, start by defining a baseline. This involves recording your current surface, methods, labour, treatment frequency, complaints, and desired outcomes. Next, you can demonstrate or hire the machine to test it on your actual site with the intended operators. Finally, measure the result by comparing productivity, quality, repeat visits, pesticide use, operator effort, and surface condition against your initial baseline to quantify the impact.

Kersten machinery played a role in Hull's broader Love Your Neighbourhood program, which focused on improving access, appearance, and surface condition across neighborhood streets. The program, which combined street cleaning, verge edging, gully work, and repairs, reached 125 streets across 11 wards. Kersten UBS power units and weed brushes were utilized within this multi-service clean-up initiative, contributing to the overall success of the council's cleansing efforts.
