Project Details:
Ringling Museum of Art
- Project Description:
This historical clerestory museum has a diverse, internationally renowned collection of fine and decorative arts. It was originally part of the 66-acre winter estate of railroad, real-estate and circus baron John Ringling and his wife, Mable. In the early 1900’s, Ringling left his art collection and estate to the people of the State of Florida, which is now one of the Gulf Coast’s premier attractions. The museum is a partially below grade sub-structure, framed with reinforced concrete slabs and beams, which are supported by concrete columns and bearing walls.
- Challenges:
The decorative marble walkways in the loggia were exposed to excessive, long term leaking. As a result, the primary reinforcing steel and beams beneath the concrete slabs corroded. In addition, transverse cracks due to lack of expansion exhibited signs of contamination with stalactite of soluble salt deposits.
- Solutions:
Overhead spalls and rust were extracted to allow for abrasive blasting; bonding and anti-corrosion agents were applied; ceiling areas were excavated and replaced with a dry-mix shotcrete application of mortar that eliminated the extensive labor delays associated with forming and pumping.
Overhead cracks were bisected at regular intervals with injection ports set on a diagonal bias, then flushed with potable water to rinse out chlorides. Cracks were immediately pressure grouted with a low viscosity, hydrophilic polyurethane resin to form a permanent, closed cell, flexible seal.
