UK wide emergency asbestos collection

In the event of an emergency, we have the capability to provide a rapid response service to any location across the UK. This quick turnaround is to reduce the impact of any fly-tipped asbestos on both the public’s health and the environment. 

Decontamination Units (DCU)

We can provide a range of DCU, most suitable for projects where hazardous waste or asbestos may be an issue. DCUs allow personnel exposed to hazardous substances to shower and change. The DCUs can be self-contained or mains connected for maximum flexibility, and the water used in the shower is filtered before leaving the DCU to ensure that no fibres escape.

 Japanese Knotweed

GD understands the importance of safely and comprehensively removing Japanese Knotweed and treating areas that have been contaminated. Following this process ensures the problem does not occur again in the future.

Our staged Japanese Knotweed treatment

Our team provides the following stage-by-stage Japanese Knotweed treatment and disposal service to commercial properties in Wales and the South West.

Stage 1 – site survey

We always recommend that our customers treat Knotweed as soon as it becomes visible; the longer you leave it to grow, the more difficult and costly the removal process becomes. GD can provide an onsite survey to identify the scope of the Knotweed growth and recommend the best form of treatment.

Stage 2 – removal and treatment of Japanese Knotweed

Our first approach is to isolate the Knotweed prior to work commencing. Isolation will ensure that any disturbance of the plant, by workers or vehicles doesn’t cause the problem to escalate. Post isolation, we have several methods to remove and treat areas contaminated with Japanese Knotweed, including excavation, herbicide injection, glyphosate injection, foundation treatment and incineration.

Stage 3 – site clearance and guarantee

Following the treatment and removal of all Knotweed waste and contaminated soils, we will ensure that the Knotweed is disposed of in a suitably licensed facility.
