Prior to being comprehensively refurbished, Swansgate had a progressively worsening condition after many years of lack of maintenance across all 10 levels of this split level MSCP.

Before: Existing Top Decks & Parapets

Before: Damaged Internal Ramps

Before: Dark & Unwelcoming Parking Environment

Detailed concrete testing including half-cell mapping and chloride content validation culminated in the design and installation of a complex corrosion management solution. In excess of 150m³ of defective concrete was removed and reinstated incorporating galvanic anodes across all levels prior to re-waterproofing of the parking decks.

The existing failed movement joints were replaced using Radflex’s S200 structural movement joint system followed by re-waterproofing of ALL decks using a combination of Sika’s RB58 deck waterproofing system (top exposed levels) and EB14 system (intermediate levels). All works INCLUDING out of hours – were phased to ensure minimal disruption for the car park’s users that had to remain in use for the entire 39-week programme.
