Basement Storage Waterproofing in Brockley, South East London

Client: Domestic Homeowner

Brief: To convert an existing damp cellar and provide Basement Storage Waterproofing in South East London

A homeowner in Brockley, South East London, was experiencing persistent damp and water ingress issues in their basement, making it unsuitable for storage. The excess moisture was damaging the structure and creating a musty, uninhabitable environment.

Advanced Preservations was contacted to implement a comprehensive basement waterproofing solution that would ensure the space remained dry, protected, and functional for long-term use.

The Waterproofing Issues We Needed to Resolve

Our initial survey identified several key issues affecting the basement:

  • Water ingress through walls, leading to damp patches and surface deterioration
  • High humidity levels, causing condensation and poor air quality
  • Lack of ventilation, allowing moisture to build up
  • Damage to existing finishes, requiring removal and replacement

To ensure the basement could be used safely for storage, a fully integrated waterproofing system was required.

Implementing the waterproofing solution

After a full assessment, we designed a custom waterproofing system tailored to the unique conditions of the basement. Unlike other projects, this basement required targeted interventions to ensure effective water management and long-term usability for storage.

  • Applying a Type C cavity drain membrane system – Installed on all walls and floors, this system allows moisture to be safely controlled and channelled away from the structure without affecting the existing brickwork.
  • Installing a Perimeter Drainage System – Since this basement had a history of water pooling in specific areas, a perimeter drainage channel was designed to efficiently divert moisture to a controlled discharge point.
  • Resin Injection for Minor Cracks – To prevent further water ingress, specialist resin injection techniques were used to seal hairline fractures in the basement walls.
  • Fitting a High-Capacity Sump Pump System – This basement had a high groundwater table, requiring the installation of a dedicated sump pump with a battery backup to handle varying water levels.

By integrating these targeted measures, the basement was permanently protected against damp ingress, creating a dry, stable, and safe environment for long-term storage use.

A Dry, Usable Space Ready for the Future

The previously damp and unusable basement was successfully converted into a fully waterproofed, dry, and secure storage space, delivering:

  • A permanently dry storage area, protected against damp and moisture
  • A practical, usable space, safe for long-term storage
  • Improved internal finishes for long-term durability
