    Introduction

    We were approached by our reseller Blue Hat Middle East about a job under a brand-new hotel in Dubai! There was an issue with concrete inside of the underground pipes and the subsequent issue with the drainage meant that the hotel was not able to open! The plastic pipework ranged from DN150 to DN200 and access was only possible through a small access hole.

    The Problem

    Reports of blocked drainage pipes following building work were a real cause for concern for the hotel owners. The hotel was not able to open until a solution was found. Due to the high-end finish of this new establishment, extensive excavation of the flooring was not a viable option. We knew that there was some concrete inside of the pipes but the extent of the blockage and the type of concrete, even the length of the blocked pipe was unknown. We discovered the details of the situation once we inspected with the CCTV cameras.

    The Details

    One section of drain running out of the hotel was blocked 100% with concrete. The drain ran under a concrete slab floor at a depth of 3 metres. The pipes also ran underneath some very very large water storage tanks! The concrete blockage started approximately six metres upstream from the tiny inspection chamber, the only point of access. The length of the blockage was still unknown. pipe concrete

     

    The Picote Solution-

    The Maxi Miller Power+

    CONCRETE REMOVALIn order to remove concrete from the pipe the Maxi Miller Power+ was the ideal machine for the job. The enormous water tanks above the problem pipes, along with the sea water-level issues meant that a deep excavation was quite literally not an option.  Training was conducted before going to site. The Twister Concrete Remover was attached to the end of the 18mm shafts and the first concrete section was successfully removed. The client was very happy.

    ...more concrete blockages!

    Concrete under the kitchens

    The next area of concern was the newly-built kitchen areas, again with blockages of concrete causing several drains to back-up. We were told the concrete was in the straight section but it was discovered in the pipe bend. A DN100 access point led to the DN150 pipe around 30cm deep. The distance to the concrete and the length of the blockage was unknown.

    A tricky situation

    The DN150 Concrete Cutter wouldn't fit through the DN100 access point for cleaning the DN150 pipe beneath. A small excavation was required at the top end only. This enabled the concrete cutting to start in the straight section of DN150 pipe.

    Problem Solved! 

    This work continued for a further 4 days working along the DN150 pipe – cutting and checking the progress with the CCTV camera. We successfully cut out 4-5 metres of concrete from the lines! 

    The kitchens were put back into service and the floor was reinstated shortly after completion. The hotel was finally able to open!
