A real life story using a Ripagreen - Groupe Sefmat Thermal Lance around my local church.

During January 2025 we started using the Ripagreen around the church on the brick gullys which normally are a magnet for weeds. Now 16 months later you can see the lack of weeds and how the Thermal Lance has kept the church weed free without pesticides with minimal number of visits. The conclusion is that hitting the weeds young and tender and doing good risk assessment (for safety), the heat just wilts the weeds as the leaves can no longer feed the root, so they just die, browned off by the sun. All the paths at the church are major thoroughfares for pets and children so it was deemed by the Vicar and congregation to keep the area chemical free, and the Ripagreen - Groupe Sefmat solved the problem.



The Challenge of Weed Control in Sacred Spaces

Churchyards, cemeteries, and other historical grounds demand a unique approach to grounds maintenance. The presence of delicate monuments, ancient stonework, and often abundant wildlife necessitates a weed control method that is both highly effective and entirely non-invasive. Traditional chemical herbicides, while potent, pose risks to the environment, soil health, and can even damage stone over time. Furthermore, public perception increasingly favors sustainable, chemical-free solutions for managing public and historical spaces.


Introducing the Ripagreen Thermal Lance: A Gentle yet Powerful Solution

The Ripagreen Thermal Lance offers a cutting-edge approach to weed management, perfectly suited for the sensitivities of churchyards. Unlike traditional flame guns that burn weeds, the Ripagreen utilises a high-volume, low-temperature heat envelope. This process heats the weed leaves to approximately 80°C, causing the protein molecules within the plant to burst and disrupting photosynthesis. The result is a gentle 'wilting' rather than charring, leading to the plant's demise without scorching the ground or risking damage to surrounding structures.


Key Advantages for Churchyard Maintenance

  1. Chemical-Free Operation: A primary benefit is the complete elimination of chemical herbicides. This protects local ecosystems, groundwater, and ensures the safety of visitors and wildlife, aligning perfectly with sustainable grounds maintenance practices. For more on chemical-free options, see The advantages of Thermal Weed Control over Chemicals.
  2. Preservation of Heritage: The precise and controlled application of heat means no corrosive chemicals or abrasive physical removal methods are used near delicate stonework, graves, or historical paths. The Thermal Weed Management process is gentle on surfaces.
  3. Exceptional Accuracy and Control: The ergonomic lance features a 360-degree rotating diffuser, allowing operators to direct heat precisely where needed. This prevents damage to desired plants and ensures effective treatment of weeds in intricate areas, such as between paving slabs or around memorial bases. The lance itself remains cool during use due to its forced airflow design, enhancing operator safety and comfort.
  4. Immediate Visible Results: Operators can see the immediate reaction of the plant to the heat, confirming effective treatment on the spot. This allows for efficient targeting and reduces the need for repeat passes in already treated areas.
  5. Environmental Responsibility: Beyond being chemical-free, thermal weeding actively contributes to an environmentally responsible approach to grounds keeping.
