The World of Concrete, which will highlight the commercial concrete and masonry industries, is one of the new features at Buildex Vancouver this year.
World of Concrete makes its convention centre debut

Show director Paul Maryschak says the World of Concrete is a smaller version of the much bigger World of Concrete show in Las Vegas, where there's 1,800 companies and suppliers spread over 900,000 square feet. The Las Vegas show has been taking place in January or February every year since the 1970s.

"We're extending a successful brand into the Lower Mainland market," said Maryschak. The World of Concrete will feature a dedicated pavilion and complimentary live demonstrations.

More than 40 exhibitors have signed up for the Buildex Vancouver World of Concrete. They include WerkMaster Grinders and Sanders Inc., Mapei Inc., Brock White Construction Materials, CCMET Group, Abbotsford Concrete Products, Custom Building Products, Solid Rock Fencing Ltd., Harris Rebar, Applied Coatings and Restoration Inc. and Vancouver ICF.

Maryschak says the main focus of the Buildex Vancouver version of the World of Concrete will be six complimentary 30-minute product demonstrations by Mapei Inc. and GST International Inc. On Wednesday, Feb. 24 and Thursday, Feb. 25, Jim Glessner of GST International Inc. will give demonstrations of Elephant Armor, a single component mortar that can be used to repair a curb, stamp a floor or overlay a runway. According to GST, Elephant Armor eliminates the cost of deconstructing and reconstructing concrete by encapsulating failed substrates, which extends their useful life.

Dave Randall, a concrete restoration systems specialist with Mapei Inc., will give four product demonstrations at World of Concrete.

On Wednesday, Feb. 24, in a session called Concrete Repair – Form and Pour Application, Randall will demonstrate Mapei's Planitop 15, a one-component, shrinkage-compensated, cementitious, fiber-reinforced, fluid concrete repair mortar.

Because it contains a corrosion inhibitor and silica fume, Planitop 15 can be used in applications such as form and pour and form and pump, where early strength and fluidity are required.

The demonstration entitled Concrete Repair – Traffic Patch Repair Application, which also takes place Feb. 24, will demonstrate traffic patch repair using Planitop 18 and Planitop 18 Extended Set (ES).

Planitop 18 is a one-component, shrinkage-compensated, fast-setting, cementitious repair mortar with a corrosion inhibitor.

It can be used on interior and exterior horizontal concrete repairs, including bridge decks and parking-garage floors.

On Thursday, Feb. 25, demonstration C04, entitled Moisture Mitigation – Self Leveling Application, will be about using Mapei products Planiseal MB, Primer T and Ultraplan LSC (Liquid Skim Coat).

Planiseal MB is an epoxy coating whose purpose is to stop moisture-related problems with toppings, and to act as a surface-consolidating epoxy primer.

Planiseal MB can reduce moisture vapour emission rates of up to 25 lbs. per 1,000 sq. ft. per 24 hour period to less than three lbs. per 1,000 sq. ft. per 24 hour period.

Randall's final demonstration will be Lightweight Leveling Application using Ultraplan Lite, which takes place Feb. 25.

Ultraplan Lite is a lightweight, self-drying, self-leveling underlayment. The Mapei product addresses the challenge of leveling on suspended concrete slabs that have sagged over time.

Ultraplan Lite is designed for leveling substrates that are not rated to carry the full weight of a traditional self-leveling underlayment or concrete basic topping material.

Although it is not a part of the World of Concrete at Buildex Vancouver 2016, the educational session called Concrete Solutions for High-Performance Buildings, which takes place Feb. 24, is the only session at this year's Buildex Vancouver that deals entirely with concrete.

The presenter is Douglas Bennion, manager, training and technical services department, Quad-Lock Building Systems Ltd., which makes and sells insulated concrete forms (ICFs).

"My presentation focuses on cost-effective methods of constructing building shells with proven concrete technology, but in a way that leaves the concrete with substantial insulating value as well as its characteristic durability and resilience to the forces of nature," said Bennion.

Bennion says one of the main features of concrete construction using ICFs is the zero permeability of walls and other elements of a building from which air can escape.

"A [recent] study sponsored in part by the BC Homeowner Protection Office has proven the absolute air-tightness of ICF concrete walls, as well as methods to insure 100 per cent water-tightness around doors and windows," he said.
