Century-old Apartment Building Gets a Roof Membrane Makeover

By Sika. 

After finding water under areas of the asphalt membrane, this Florida apartment building was repaired using Sika roof membrane products. 

The Flori de Leon Apartments in St. Petersburg, Florida has been going strong since the 1920s. The same couldn’t be said for their roof. After discovering extensive damage to the existing membrane, the contractor relied on using Sika products to get the job done right. 

During the pre-construction investigation, water was discovered under portions of the existing asphaltic membrane. Those areas had to be cut out, allowed to dry and replaced with a similar asphaltic material prior to the RoofPro membrane installation. There were also some areas on the roof where the existing concrete deck had deteriorated significantly and had to be repaired with SikaQuick 1000 repair mortar. 

Project solutions 

The total area repaired came to around 5,000 square feet utilizing a 15 Year Sikalastic-624 RoofPro membrane. Sikalastic®-624 WP Waterproofing System combines a cold liquid-applied, aliphatic, single component, alkali resistant, moisture-triggered polyurethane resin with fiberglass mat or polyester fleece reinforcement to create a seamless membrane and flashing system. Typical applications include a separate wearing course (overlayment or overburden), but Sikalastic®-624 WP Waterproofing System is UV resistant without protection board and is therefore suitable for direct exposure waterproofing applications as well.
