J UNE 2017 | 51 Waterproofing the Maxxon Damp Proof Membrane (DPM). The DPM is a unique two-component, moisture tolerant, high density, chemically enhanced epoxy product that prevents the passage of water vapour and moisture through concrete floors and walls, on or below grade. A unique feature of the Maxxon DPM is it allows for a sand broadcast during installation. The sand broadcast provides a great textured surface to bond a Maxxon Underlayment. The MVP is also a two-component system: a moisture tol- erant, high density, chemically enhanced epoxy product that prevents the passage of water vapour and moisture through concrete floors and walls, on or below grade. Also from Maxxon, the Enkadrain exterior underslab drainage system solves concrete slab moisture issues by moving water away from the concrete substrate via a post-industrial recycled core of fused, entangled filaments and a geocomposite fabric bonded to each side. The filaments are molded into a square waffle pat- tern that maintains the flexible design of other Enkadrain products (and because it exceeds 40 percent post-industrial recycled content, it can help contribute LEED points when used in conjunction with other recycled content products). Crystalline admixtures, polyurethane coatings and acrylic polymer-based cementitious coatings are all gaining in popularity as waterproofing agents in Canada, and many buildings in B.C. are benefitting from crystalline admixtures such as Eucon Vandex AM-10 from Euclid Canada. For example, it was used as an extra precaution to prevent weeping from below in the MThree residential com- plex by Cressey Development Group, in all the concrete around the entire core and the top one foot of the raft slab. Eucon Vandex AM-10 is formulated to interact with concrete capillary pore struc- tures and provides a waterproofing system that is a permanent part of the concrete matrix, whether in above- or below-ground applications. Much like Euclid Canada, BASF is famous for chemical formulations that have advanced many industries. In the construction realm, BASF has developed a port- folio of technologies to help contractors, concrete producers, design professionals and owners achieve watertight concrete structures, and the versatility of its fast- curing hand and spray-applied waterproofing technologies also meets refurbish- ment and protection needs. For example, MasterSeal AWB assemblies are designed for use behind all clad- dings and at rough window treatment and create a seamless air/water-resistive barrier and flashing system for all walls on a project, while the MasterLife 300D admixture is an integral crystalline capillary waterproofing for concrete in above- and below-grade applications. In terms of membranes, BASF's MasterSeal 345 is spray-applied between layers of sprayed or cast-in-place concrete, and it can also be used as a stand-alone membrane, exhibiting high bond strength to the substrates on both sides of the membrane with good elasticity. Finally, with regard to water resistant coatings for exterior above grade walls, DuRock architectural coatings and exterior insulation finish systems are said to be changing the face of architecture, with architects and builders increasingly choos- ing acrylic coatings over conventional building systems due to their ability to maxi- mize energy efficiency and reduce moisture penetration. Specifically, the company's PUCCS EIFS systems, whose core is a geometrically defined drainage cavity, is considered to be the ultimate in continuous insulation rainscreen cladding technology. PUCCS systems have been tailored for commercial and high-rise applications; residential and low-rise use; and for insulated concrete forms. The system includes first and second planes of protection from precipita- tion, and the geometrically-defined drainage cavity is 10-millimetres deep and 37 percent open. As for coatings, DuRock's Tiocoat is a high-strength elastomeric coating that provides superior weather resistance as well as reflectivity, resisting abrasion, biological growth, and extreme weather conditions. "This is basically a protective membrane that goes on top of roof systems and can be applied to a wide variety of roofs such as BUR, Mod-bit, EPDM, concrete and asphalt," says Andre Turrin, tech- nical director for DuRock. Everything in the waterproofing realm is changing, arguably for the better. In drainage, there's a move away from the traditional gravel approach to more mod- ern materials such as dimple drain sheets, perforated pipe and geotextile systems. Polyurethane and acrylic coatings are increasingly the formulations of choice for professionals, and it's rapidly reaching a point where waterproofing specialists know more about sumps and sump pumps than plumbers. In short, there are more ways than ever to address waterproofing and water resistance in their myriad forms on any construction project; the key is to match the excellent attributes of products with careful craftsmanship.
