JKSL undertake a highly professional and systematic approach to every project. Our main services are detailed below.
ADVICE: Japanese Knotweed Solutions is a leading authority on the problem and we invest heavily in raising awareness of Japanese knotweed and other invasive plants within the construction industry. Early identification can significantly reduce cost implications and timescales involved in removing Knotweed from the development.
INVASIVE PLANT SURVEY: JKSL will conduct a thorough visual inspection of the site for the presence of Japanese knotweed and other invasive plants. We will assess the site conditions, potential risks and contamination pathways. We will produce a detailed invasive species location plan in AutoCAD, confirming the exact size and location of the infestation. Our surveyor can overlay your development plan with the infestation areas to work out exactly how your site will be affected.
PROPOSALS: A detailed survey report will be produced to outline our findings, provide recommended remediation strategies and calculate associated costs. We will also include site photos, assessment of site plans and any recorded environmental concerns and hazards.
TREATMENT: Herbicide treatment remains the most cost-effective solution for Japanese knotweed treatment. The methods of herbicide application include knapsack blanket spraying, stem injection and leaf wiping. In areas of high sensitivity (such as SSSI sites, adjacent to water courses or near protected plant species) stem injection or leaf wiping may be required.
Mechanical excavation offers an efficient solution where herbicide treatment in-situ is not a viable option. This would include development projects or ground works whereby Japanese knotweed impacted soils would be disturbed. JKSL manage all aspects of the mechanical works in-house, including planning of works and production of RAMS, completion of works on site, management of waste transfer and grading/backfilling to make the site safe.
SITE MONITORING AND INSURANCE BACKED GUARANTEES: JKSL provide ongoing monitoring and treatment of sites to ensure successful results. We offer a 10 year insurance backed guarantee on all Japanese knotweed remediation works carried out by JKSL. We are accredited members of industry trade bodies, the Invasive Non Native Specialists Association (INNSA) and the Property Care Association (PCA). The policies provide our clients with the confidence that works have been carried out by an accredited specialist contractor. Should invasive plant re-growth occur following remediation, it is covered by our robust guarantee.
