DRE is pleased to announce the addition of Stego Industries to our line of products.

Stego Industries is the industry leader in the below-slab vapour barrier market. They strive to provide valuable solutions for moisture-related concerns by providing quality products and continuous support. The products are composed of the highest quality, virgin resins and provide superior protection against the costly problems associated with below-slab moisture migration. This will become increasingly important in September of 2010 when the VOC laws are implemented and solvent based adhesives are no longer compliant.

An issue that seems to be on everyone's minds these days is the July 1st implementation of the HST. The Sealant and Waterproofing Association is hosting a lunch seminar on April 28 to discuss the new tax and answer some of the commonly asked questions - How will the HST affect my business? Will customers be entitled to a PST rebate after July 1st? How will the HST affect my progress payments and hold backs? Click on the link to the left for more information.

As always, I am open to suggestions and comments so please feel free to email me at marla@dre.ca.

Best Regards,

Marla

What is the difference between Stego Wrap and the vapour retarders that I have been specifying?

Older generation vapour retarders/barriers fall into four categories...

1. Cross-laminations of very thin mils of polyethylene
2. Laminations of alternating layers thin polyethylene and scrim
3. Thin polyethylene with fabric laminated to one side
4. Laminations of thin polyethylene, scrim and brown paper

Stego Wrap is a "new generation" product extruded from prime virgin resins and additives on a first melt basis. Stego Industries does not use low-grade resins, recycled or reground materials, cross-lamination, layers of scrim or fabric backing. Virgin plastic molecules in Stego Wrap "cross-link" to provide a homogenous membrane with the same permeance and puncture resistance throughout the web of the film.

STEGO WRAP Vapour Barrier is easily
unrolled and cut to size, safe to walk upon.

Project Profile: Sherbourne Park

Coreflex 60 is currently being installed at Sherbourne Park by Aquanorth Contracting. This project has been receiving lots of press lately for its unique design and functionality.

Sherbourne Park will be a spectacular new park in the heart of the East Bayfront midway between the Jarvis and Parliament Street slips. It will be both a local and regional amenity. The park will extend from the water's edge to Lake Shore Boulevard, bisected by Queens Quay. It is envisioned as an urban room and will provide a strong terminus at the foot of Sherbourne Street. On the east and west sides, the park will be bound by buildings with a weather protected arcade creating a link to the waterfront during all seasons. At its southern end, the park will be integrated with the continuous water's edge promenade and will be designed to reinforce and strengthen the water's edge as a continuous and active year round destination. Park programming could include a large public gathering place and a water feature that could be frozen in the winter for skating.

In addition to it being a park, it is a Storm Water Treatment Facility. This project is the first of its kind in Canada.

SecuritySeal: Pick-Resistant Sealing and Fire Rating to Structural Joints

Pick-Resistant, 2-Hour Fire-Rated, Sound Blocking, Watertight, and 50% Movement--One Product, One Install Does it All

EMSEAL is pleased to announce SecuritySeal--another new product tested and certified by Underwriters Laboratories to the rigorous requirements of UL 2079.

SecuritySeal is a pick-resistant, watertight, 2-hour fire-rated, expansion joint for locations requiring a hardened tamper-resistant surface. Institutional walls such as those found in prisons, detention centers, medical and psychiatric hospitals, school facilities and day-care centers are some of the many structures for which SecuritySeal is the ideal choice.

The system is comprised of fire-retardant-impregnated foam which is factory pre-coated on both outward facing sides with an intumescent fire-proofing material. Each side then receives a top coat of waterproof, tamper resistant polyurethane.

The system is supplied compressed smaller than the width of the joint gap. The precompressed foam is installed into an epoxy adhesive applied to the substrates. A field-injected polyurethane sealant band seals the bellows to the substrate at the installation surface in weather-facing applications. Joins between each stick are executed using a field-applied polyurethane sealant at the bellows' edge of the join and intumescent caulking on the foam face.

SecuritySeal functions as a watertight primary seal with movement capabilities of +/- 25% (50% total) available in widths for gaps ranging from 1-inch to 6-inches (25mm - 150mm). It is designed to be used in both retrofit and new structural expansion joints and in all other openings in vertical-plane applications and is uniquely suited to precast tilt-up as well as block and cast-in-place concrete construction.

Technical Resources -
Revised with a new look...

NEOGARD introduces the next version of the Technical Resources website that has been given a new look for easy access to guide specifications, product data sheets, detail drawings, contacts, technical articles, credentials and ratings, warranty information, MSDS, maintenance manuals, project profiles and more. This new version is a work in progress. Over the next few months, the new look will be phased in with the old being phased out as the new Marketing portion of our website is brought on line.

Protectosil® for Parking and
Bridge Decks

The main deterioration mechanism for concrete decks is corrosion of reinforcement and scaling of concrete. Protectosil products for concrete decks are designed to repel water and chlorides, reducing deterioration and increasing surface life. Protectosil products penetrate deeply to provide long service life even on wearing surfaces. Because they do not change the skid or slip resistance of the concrete, they are ideal for driving surfaces..

Protectosil® BH-N is a deep-penetrating 100% silane.
Main Benefits: Low-temperature application (20°F), Excellent long-term chloride screening on wearing surfaces (bridge decks, parking decks)

Protectosil® CHEM-TRETE® 40 VOC and Protectosil® CHEM-TRETE® 40 H are both solvent-based silane systems.
Main Benefits: Fast dry time, Low-temperature applications (20°F)
Please note these products do not meet the new 400 g/lt Canadian VOC requirement effective September 9, 2010.

Protectosil® AQUA-TRETE® 20 and Protectosil® AQUA-TRETE® 40
are water-based silane emulsions in 20% and 40% concentrations.
Main Benefits: Non- flammable, Low odor

KOSTER NB1 Waterproofing System

The KOSTER NB1 Waterproofing System has been developed to waterproof cement-based substrates through the process of crystallization. KOSTER NB1 contains chemicals which react with moistureand ingredients in the substrate to form crystals which penetrate deep to fill the voids and capillaries to produce the waterproofing effect. KOSTER NB1 becomes an integral part with the substrate itself. KOSTER NB1

KOSTER NB1 may be used on the positive as well as negative side of structures. It resists water pressures in excess of 400 feet and may be considered a permanent waterproofing system as long as the substrate remains sound. KOSTER SB Bonding Emulsion

Even freezing and thawing cycles will not negatively affect the material. It has excellent abrasion resistance and does not require protection board for backfill.

KOSTER NB1 is supplied in powder form. It is mixed with a solution of KOSTER SB Bonding Emulsion and water. The SB Bonding Emulsion is added to improve the curing and adhesion to steel when waterproofing between steel and concrete takes place. The SB Bonding Emulsion also improves the abrasion resistance and elastic (lower modulus) properties of the material.
