Two recent apartment refurbishment projects we have worked on have had steel corrosion as the cause of finished surfaces blowing out.
- Steel lintels corroding inside block-work cause oxidization within the mortar resulting in expansion and eventual cracking.
- Treatment to the exposed underside of a lintel is very different to the embedded section of the lintel within the blockwork, which will require grinding back of rust, drill test of depth of corrosion and a 3 x coat specialist system including a mortar product. The specialist system seeps back through the mortar coating the lintel surfaces.
- Steel balustrade bases which start to corrode can cause tiling laid over the top to crack and buckle.
- Exposure of the surface, grinding back of rust and a 3 x coat treatment system is required before re-laying of tiles.
