    Faced with an extremely challenging culvert, this historic brick arch required precision and caution due to its fragile nature, susceptible to damage if mishandled. TDG Environmental was tasked with cleaning out the culvert chamber, measuring nearly 30m in length and 2m in width.
    TDG Environmental was reached out by a local council to clean and clear the blockages at the inlet. The client was also aware that we were unable to clear the blockages without Ultra High-Pressure Water Blasting (UHPWB).
