Structural Steel

Underlying structural steel elements may be so deteriorated that they must be repaired or even replaced. RBS has the capability to remove external masonry cladding and complete essential repairs to the steel structure.

Sealant Replacement

RBS can replace failed, cracked or loose caulking at windows, doors, and other wall penetrations. These are often the most vulnerable building areas for water infiltration.


RBS can replace loose, cracked or missing mortar in masonry walls. Good, clean tuckpointing and careful mixing of mortar to blend in repairs can restore a building to prime condition. The process can also detect mortar problems which can lead to shifts in masonry – the cause of larger infiltration opportunities and even threatening the structural integrity of the wall.

Concrete Restoration

Concrete building framing members, panels and reinforced balcony slabs can crack and allow moisture to enter the building itself or attack the reinforcing steel. RBS can repair cracks and replace entire cladding or slabs.

Terra Cotta Stone

Building decorations exposed to weather for long periods deteriorate and lose luster, spoiling the appearance they were designed to enhance. They can also crack and loosen over time, presenting potential fall hazards. RBS can repair or recreate these decorative elements and safely restore them to their original beauty.
