Date of Project: September 2017Project Owner: Cairns Regional CouncilProject Contractor: Waterstop Solutions Pty, LtdProject Engineer: Cairns Regional Council Market/Environment WastewaterSubstrate: ConcreteSize of Project: 12 x 2m joint replacementTHE CHALLENGEThe joints on a municipal wastewater treatment tank had degenerated to the point where repairing and resealing were necessary. Cairns Regional Council required a product with a fast cure time and rapid compressive strength gains.Five Star® SolutionFive Star Structural Concrete® V/O was selected due to its rapid set and high early strength gains; it reaches 2,500 psi (17.2 MPa) within three hours. This rapid strength gain allowed for the repaired joints to be resealed with minimum turnaround time in preparation for the installation of a joint sealant system.ABOUT FIVE STAR STRUCTURAL CONCRETE® V/OThis is a high-strength, rapid-setting, one-component, permanent concrete repair material for vertical and overhead structural repairs.It produces a repair that is dimensionally stable, develops an integral bond to existing concrete, and restores structural integrity within hours of placement.Provides increased corrosion protection to steel-reinforced structures with migrating corrosion inhibitor technology and very low chloride ion permeability. Moisture-sensitive coatings can be applied in 8 to 24 hours.Can be troweled vertically or overheadOne product for thin and thick placementExcellent freeze/thaw resistanceOutstanding corrosion resistance for protection and rehabilitation

T: Offer Luzon / HAGIVA Y.H.: Priel LewMARKET/ENVIRONMENT: InfrastructureSUBSTRATE: Steel/ConcretePRODUCTS USED: Five Star® Fluid Grout 100 and Five Star® GroutPROJECT SIZE: Five Star Fluid Grout 100: 30,000 Kg / Five Star® Grout: 55,000 KgTHE CHALLENGETo construct an environmentally friendly, covered, 30,000-seat stadium in Israel's largest city of Haifa for the convenience of spectators, players, and judges. As such, two of the country's predominant construction entities were selected. A partnership was formed between Electra BST Registered Partnership and constructor Yossi Shiran, the largest engineering company in Israel, to complete this 80-million-dollar stadium over the course of five years.THE SOLUTIONFive Star® Fluid Grout 100 and Five Star Grout enabled contractors to create a unique stadium that is both meticulous and intentional in catering to the convenience of its visitors and players. Five Star's industry-leading cement-based, non-metallic, non-shrink Fluid Grout 100 and Five Star Grout were integral to the stadium's construction.

Date of Project: August - September 2014Project Owner: Occidental PetroleumProject Contractor: Hugh Roberts ConstructionMarket/Environment: Oil ProductionSubstrate: Gunite from the 1960sProduct Used: Five Star Structural Concrete V/0®Project Size: 500+ PailsProject DetailsIn 1965, four artificial islands were built in San Pedro Bay off the coast of Long Island to conceal oil pumping stations. In the year 2000, Occidental Petroleum purchased the islands, known as THUMS Islands or Astronaut Islands, and operations. The islands contain significant landscaping, a waterfall, and tall structures concealing the drilling rigs, including one known as The Condo and often mistaken for "a ritz hotel" by those on land. Island Grissom is the closest to land and contains more sculptured screens than the other islands.The ChallengeOver the years, wind and water have taken their toll on the concrete structures around the island, causing a great deal of deterioration. A few obstacles to overcome were:The depth of repair (Tapcons were driven into the substrate for added reinforcement in the deeper areas of repair)Direct sun/heatHeight of repair was as high as 100 feetLimitations on water saturation for presoak and wet cure.Deliveries had to be scheduled precisely as all products had to be shuttled over to the island via ferry.Five Star® SolutionChosen for this demanding repair project was Five Star Structural Concrete® W/O because of its rapid-setting properties and ability to be used on vertical and overhead surfaces. Moisture-sensitive coatings could also be applied in 8 to 24 hours, speeding up repair time.This high-strength, permanent concrete repair material allowed the workers to make repairs quickly and efficiently, using only one product for thin and thick placement.
