Case Study

Step Subsidence & Brickwork Repair

Stadium Support Services was called to site following reports of step subsidence and trip hazards affecting public access. Concerns were raised regarding below-ground conditions and the possibility of an underground leak. Our investigation revealed a series of structural and installation issues that required immediate remedial work to ensure long-term safety and stability.

The Challenge

The client raised concerns after noticing that the external steps were subsiding, creating trip hazards and posing a safety risk. There were suspicions of a possible underground water leak causing ground movement.

The top landing area appeared uneven and unstable, raising concerns about long-term integrity. Around the building’s lower perimeter, brickwork was also deteriorating — likely caused by frost damage — and required inspection and repair

Scope of Work

  • Investigate the suspected water leak and ground instability
  • Remove all affected steps and paving slabs
  • Reinforce the sub-structure and tie into the existing stair system
  • Repoint frost-damaged brickwork across ground level elevations

The Solution

Our multi-access teams used a combination of rope access, MEWPs, PASMA towers and temporary fall arrest systems to safely reach all areas of the internal undercroft and external superstructure. Steelwork was prepared to ST3 standard, feathered back and fully recoated using an approved three-part protective system. Cleaning teams used abrasive brushes and ground-fed water lines to deep clean high-level steelwork with minimal disruption. Thanks to strong planning and a flexible on-site presence, both projects were completed safely and within the required timeframe.

To resolve the issue:

  • All steps and slabs were removed
  • The void was filled with poured concrete to create a solid base
  • A new structural tie connected the plinth to the main stair structure
  • Steps and slabs were reinstalled using compacted hardcore and correct sub-base
  • Exclusion zones were maintained until fully cured

Frost-damaged brickwork was also repointed around the perimeter up to 1 metre high, where weather exposure had caused deterioration.
