Spray lining is increasingly being used as a preventative rehabilitation method for small drainage structures where intrusive works are not practical or would pose environmental risk. By spraying a fast-curing resin directly onto the internal surface of existing assets, a seamless protective lining is created that helps prevent leakage, corrosion and environmental contamination while extending the service life of the structure.
This approach was recently used to rehabilitate leaking gullies located within a fuel farm bund, where maintaining environmental protection and site operations was critical.
Gullies located within a fuel farm bund were leaking, allowing fuel to contaminate the surrounding ground beneath the bunded area. Due to site constraints and the sensitive nature of the environment, excavation was not possible. A non-invasive solution was required to prevent further contamination while maintaining site integrity and operational continuity. While associated pipework was repaired using localised patching methods, the gullies themselves required full internal rehabilitation.
Spray lining was selected as a trenchless rehabilitation method, enabling the gullies to be sealed and restored in situ without disturbing the bund or surrounding infrastructure. For this project, the XS Spray Lining Machine from Relining Group, supplied by S1E Ltd, was used to apply ElastoFlake Polyurea resin and create a seamless internal lining. The application process was controlled and consistent, and well-suited to the confined and environmentally sensitive conditions present on site.
The works were delivered by Adler & Allan, with support provided by Danny Topham, Technical Support & Service Technician from S1E to assist with the system setup and application guidance throughout the project.
Given the location within a fuel storage environment, the selected polyurea resin was required to demonstrate resistance to specific chemical exposures. Following verification of its compatibility, the ElastoFlake resin proved to be an appropriate and reliable choice for the application, supporting Adler & Allan in delivering a compliant and durable repair for many years to come.
A key advantage of the system is its rapid curing time. The resin sets in just three minutes, significantly reducing downtime and allowing the gullies to be returned to service almost immediately. In operational environments such as fuel storage facilities, where disruption must be carefully managed, this rapid turnaround provides a clear practical benefit.
The result was a fully sealed and rehabilitated gully system achieved without excavation and with minimal disruption to site operations. The fast-curing, chemically resistant lining provided immediate protection against further leakage and contamination, delivering a durable solution in a technically challenging setting.
This project reflects the growing demand for spray-in-place rehabilitation of small drainage structures in restricted-access and environmentally sensitive locations. Through S1E’s exclusive partnership with Relining Group, these systems are available to UK contractors, supported by technical guidance and training where required.
