Masonry goes back to the beginning of time, even before the astounding pyramids of Egypt. As professionals seek to emulate the natural beauty and durability of Mother Nature’s masonry wonders, such as the rock formations of Monument Valley in Utah and Arizona, we are continuously reminded of and awed by the benefits that masonry offers to commercial and residential applications. And, while beauty and durability have been the traditional appeal, the modern era has shown us a new face to masonry, and it’s green.
The green movement and LEED Building Rating System initiatives have swept the construction industry and taken masonry by force. Leading the way is masonry’s innate characteristic of durability. However, it is prone to create waste, and it has a lack of energy efficiency if it’s not properly insulated. Its impervious surface, when used as a ground cover, can destroy all the good this sustainable building material generates.

Masonry veneer system
Properly installed, and more important, properly insulated, masonry veneers may well see an increase in demand from both the green and aging-in-place movements. While masonry veneers provide a low-maintenance and durable exterior solution, they also are more beautiful than other options and can produce energy savings of up to 30 percent with proper insulation. All of these benefits combined with the cost and time advantage of using a masonry veneer versus full-stone installation, makes this cladding option quite appealing to both businesses and homeowners.
A new masonry veneer system just being introduced to the U.S. market combines concrete masonry stones and clay brick with insulating polystyrene foam panels and specially designed mortar to create a veneer system with an R-13.5 insulation factor. Suretouch by Oldcastle has been growing in demand in Canada since its introduction in 2006.
SureTouch’s innovative technology pairs masonry’s durability with foam insulation panels to create an R-13.5 insulation value for energy savings and acoustical comfort. Drainage channels found on both sides of the foam panels naturally drain away any water that might infiltrate the veneer.
The foam panels are attached to the home’s exterior using stainless-steel screws and anchors. The Suretouch masonry units then are placed into pockets in the panels, taking the guesswork out of the stone placement and masonry pattern. Finally, specially designed mortar seals the system together and to the frame of the home, making a finished home exterior that is low-maintenance and durable, providing significant energy savings contributing to the home’s green status.
Permeable pavers are allowing governments, businesses and even homeowners to take responsibility for managing storm water runoff. As part of a bio-aquifer storm water system, permeable pavers can virtually eliminate runoff, potentially removing the need for retention ponds or underground sewer pipes.
In September, Belgard Subterra permeable pavers were used in a 9,000-square-foot parking lot at HealthNet People’s Health and Dental Center in Indianapolis. As part of a demonstration project for the City of Indianapolis’ Office of Sustainability, officials simulated a flash flood, dumping more than 4,000 gallons of water on the lot in a matter of 15 minutes. The demonstration was equivalent to the area receiving nine inches of rain. The parking lot produced no run-off.
Permeable pavers like Belgard Hardscapes Environmental collection can reduce runoff by as much as 100 percent, while providing an aesthetically pleasing and easy-to-install alternative to impervious paved surfaces. Belgard Subterra emulates the look of naturally chiseled stone, and Aqua-Roc provides a smooth surface that is comfortable for bare feet but strong enough for vehicular traffic. An additional benefit to using permeable pavers is the simple installation. The 9,000-square-foot HeathNet Center lot was installed in three weeks, and once installed, it was ready to use.
And the permeable market is not just for municipality and commercial installations. When the outdoor living trend took off in the early- to mid-2000s, it expanded the demand for outdoor masonry structures, including retaining walls, fireplaces, outdoor kitchens and decorative, yet functional, groundcovers, such as pavers. While some homeowners may not worry about the small square footage of impervious surface their outdoor living space creates, environmental stewards may be seeking a solution that is easily found through permeable pavers.
The green movement is here to stay and will only increase in demand as government regulations require more construction projects to abide by green standards and practices. With masonry’s aesthetic appeal and innate durability, it stands to gain in popularity and demand from the green movement if professionals are smart about products and practices used.
