Project Showcase

BROMOCO Network, a distinguished building restoration contractor, embarked on a formidable project to rejuvenate the stainless steel baffles adorning the High Rd. Leyton Pedestrian Bridge. Commissioned by Waltham Forest Council, this endeavor presented a myriad of challenges, demanding a delicate balance between intricate engineering solutions and the complexities of operating in a bustling urban environment. This comprehensive case study delves into the nuanced engineering overviews, the meticulous selection and application of specialized products such as ERW-BD, ERW-XL, and EPC-7460A, and the strategic problem-solving that ultimately defined the success of this intricate restoration project.


Preliminary Survey

The initial survey uncovered a stainless steel baffle exhibiting severe damage, marked by scratches, scale, bird droppings, and corrosive signs. The multifaceted contamination required an all-encompassing cleaning and protection product, especially considering the bridge's proximity to Leyton Underground Station and the motorway running through the center. The 80-meter length and 1.7-meter height of the stainless steel baffles on both sides posed a challenge, demanding a tailored approach to restoration.


To address these concerns, BROMOCO Network evaluated the extent of the damage and the unique challenges posed by the location. The complexity of contamination, ranging from scratches to signs of corrosion, prompted a comprehensive solution. The high volume of pedestrian traffic and the proximity to Leyton Underground Station demanded an approach that minimized disruption, making it imperative to select cleaning and protection products that could operate effectively in such a dynamic environment.


Construction Site Survey


The construction site survey involved a detailed analysis of the site dynamics, considering the pedestrian access points, the viaduct, and the motorway. The challenge lay in maintaining a delicate balance between restoration efforts and minimizing disruptions to pedestrian traffic.

Logistics planning became crucial, considering the need to manage high pedestrian traffic and ensure minimal disruption. Additionally, the environmental standards mandated careful planning for the disposal of waste liquids into the sewer, aligning with stringent discharge standards and showcasing a commitment to responsible construction practices.


Product Selection: ERW-BD, ERW-XL, and EPC-7460A

The product selection process played a pivotal role in the project's success. ERW-BD, a biodegradable degreaser, emerged as a cornerstone in the cleaning and preparation phase. Its versatility, low odor, and eco-friendly attributes made it an ideal choice for addressing the diverse contamination on the stainless steel baffles. For more stubborn rust stains and dirt, ERW-XL rust remover was introduced, ensuring a thorough cleaning without compromising the integrity of the stainless steel's finish.


The protective phase introduced EPC-7460A, a crystal-clear coating designed specifically for stainless steel surfaces. Its remarkable features, including resistance to oxidation, staining, and bacterial growth, made it the optimal choice for long-lasting protection. The selection of these products was not arbitrary; rather, it stemmed from a detailed analysis of the project's requirements, considering the type of contamination, the environmental standards, and the need for a durable protective coating.


Project Plan and Execution

The project plan and execution phase involved a detailed timeline for the application of ERW-BD, ERW-XL and EPC-7460A. Rust removal with ERW-XL and cleaning stainless steel surfaces with ERW-BD required a systematic approach, ensuring that all areas were thoroughly treated.


Given the high footfall and open-air conditions, the protective coating had to be applied multiple times, demanding effective measures to avoid contamination. The challenge of occupying a pedestrian access area emphasized the need for swift and efficient execution, prompting the team to adopt measures that minimized disruption while achieving the desired restoration results.

Problem-solving and adaptation were critical components of the project's execution. The challenge of controlling product volatilization and splashing, especially in a high-traffic urban setting, demanded the implementation of strict safety measures. The need for multiple applications of the protective coating called for strategic scheduling and coordination to ensure that each layer adhered effectively. Adapting to the dynamic nature of the construction site, unforeseen challenges were met with agility, showcasing the team's ability to navigate complexities and ensure a successful restoration.


Environmental Responsibility

The environmental responsibility aspect was woven into the fabric of the project, influencing decisions from product selection to waste disposal. The commitment to high environmental standards dictated the disposal of waste liquids into the sewer, aligning with strict discharge standards. The eco-friendly nature of ERW-BD and ERW-XL, coupled with the thin & virtually invisible coating and low organic volatiles of EPC-7460A, reflected a conscientious effort to minimize the project's environmental impact. The adherence to sustainability principles extended beyond mere compliance, showcasing a genuine dedication to responsible construction practices.
