Chemical Resistant Coating for a Water Company
The client had an old FST tank that was suffering from Acidic corrosion to the scum channel.
Description.
The client had an old FST tank that was suffering from Acidic corrosion to the scum channel.
The client had an old wet well that had the cover slab damaged during emergency works and due to the levels of Hydrogen sulphide gas (H2S) within the sewer and no chemical dosing local to the site so the client required protection against acidic corrosion to the concrete cover slab
The client had a new wet well that was being constructed and due to the levels of Hydrogen sulphide gas (H2S) within the sewer and no chemical dosing local to the site so the client required protection against acidic corrosion of the concrete to the top 2 meters of the wet well and the cover of the wet well.
The concrete bund was deemed an environmental concern as containment could not be assured due to the level of deterioration of the concrete elements of the bund and sealant joints due to chemical exposure and general environmental degradation.
The Developer had a requirement to increase the existing buildings height to create an apartment complex, however, due to the underlaying soils ground bearing capacity not being suitable, a geopolymer solution was developed and designed in collaboration with the client’s structural engineer to facilitate the build.
A piling contractor was experiencing water ingress through a seacant piled wall which was stopping the waterproof membrane contractor installing their structural waterproof tanking system
A construction contractor had Service penetrations that were within service manholes that required making good and providing a permanent waterproof seal.
A construction contractor had cored through waterproof concrete walls and soffits to install service penetrations for the electrical, gas, drainage, sprinkler systems, air conditioning and water services which meant that these penetration were not fireproof or watertight.
A construction company were ready to start installing the lift within when they noticed that the lift pit was experiencing water ingress. The lift engineering company had stated that they would not install the lift until the lift pit was watertight.
A lift engineering company were carrying out their 6 months service and inspection programme to an existing lift installation and witnessed water ingress coming into the lift pit. The water ingress was also causing corrosion to the lift components which left untreated would rendered the lift unserviceable.
The client had requirement to waterproof localised areas of masonry to arrest running water that was causing damage to brickwork, overhead powerlines and track.
The client had a requirement to consolidate and fill voids to the ground at the back of the piled wall, which was identified due to the movement of the front façade of the building and the neighbouring 3 party structure. This was assumed to have been caused by the poorly constructed piles, and fines wash out during the excavation process.
