Project Duration

20 weeks (June 2024 – November 2024)

Key Elements

High-Pressure Cleaning

Thorough cleaning of all concrete panels to prepare surfaces for treatment.

Concrete Repair

Identified areas requiring repair, particularly steel reinforcement protection, using Sika MonoTop 1010 primer and Sika MonoTop 615 repair mortar.

Protective Coating Application

Two coats of Sika’s anti-carbonation system applied, including Sika FerroGard 903 and SikaGard 706 Thixo hydrophobic impregnation.

Type of Project

Anti-Carbonisation & Migrating Corrosion Inhibitor Project

Overview

Project Solutions (a division of TPS360) was appointed as the Principal Contractor for the University of Bath’s Norwood & Wessex House project. The goal was to apply an anti-carbonation and corrosion inhibitor protection system to the buildings’ façades, enhancing the concrete’s durability and structural integrity to prevent carbonation degradation and ensure the buildings’ long-term reliability.

Challenges

The project faced several challenges, including access constraints, adverse weather conditions, and the need for additional concrete repairs.

Extensive scaffolding and access cradles were required due to the building’s height and the span of the façades.   Weather conditions, including high winds, rain, and temperatures below 5°C, posed potential delays, but these were effectively managed to keep the project on track.

During detailed inspections, it was found that approximately 10% of the panels required additional repairs. These repairs were carefully coordinated to minimise disruption to the overall schedule. Throughout the project, rigorous adherence to CDM regulations ensured safety, with regular audits and certified operatives on-site.

Outcome

The project was completed ahead of schedule, delivering enhanced structural integrity, and extending the lifespan of the façades.
