Sika concrete repair and protection system restores Rose Hill Garage

Sika concrete repair and protection system restores Rose Hill Garage

Sika have supplied the total concrete repair and corrosion management system to restore Rose Hill Garage in Oxfordshire. The garage was showing signs of spalling and degradation on the concrete walls.

Contractor, Pikehaven, was selected to install Sika’s long-term repair and protection programme restore the building’s aesthetic.

A concrete soffit attached to a ramp used to enter the garage was the main focus of the refurbishment.

Its degradation was due to chloride contamination of its steel reinforcement, leading to manifold spalling and fissures.

Carbonation and hammer tests were carried out to locate the defective areas of concrete.

Exposed reinforcement was then cleaned in readiness for the installation of Sika Galvashield®-CC 100 anodes.

The anodes control corrosion activity and prevent the new formation of corrosion sites on reinforced structures.

The defective areas were then primed using Sika Monotop®-610, a high-performance, one-component, cementitious polymer-modified protection coating, and reinstated with high-build, hand-placed concrete repair mortar, Sika Monotop®-615.

Once cured the total soffit area was pressure washed and primed using Sikagard®-552w aqua primer.

The total area was then applied with two coats of Sikagard®-550w, a plasto-elastic, anti-carbonation coating.

Tom White at Pikehaven said: “Sika was able to provide a start-to-finish concrete repair and protection solution. It is as safe and easy to apply as it is superbly effective. There is no doubting the Galvashield system’s quality.”
