38 LC DBM restores pavers by cleaning and sealing them (see sidebar, page 36). 2016 was the first year for the new company and Rhodus reports that it went well. They had to add a second crew part way through the season and are considering a third crew this season. Also this year, Rhodus will be partnering with other contractors around the country to offer the service in their locales, and is looking for more. He says that an ideal candidate is someone in the hardscape industry so they can identify repairs that are needed, is customer oriented, and perhaps feels it is time for less strenuous work than carrying loads of pavers all day. And further down the road, Rhodus hopes to franchise the concept, and make Two Brothers a company run by, well, two brothers again. Above Before any of the pavers were set, Curvrite heavy duty aluminum edging was fastened to the concrete pad with a powder-actuated gun (see sidebar) and 1" steel nails. SEK Surebond's PolySweep sand was used in the driveway's joints but to drain any water that might find its way between the pavers, weep holes were first drilled in the concrete pad and filled with pea gravel. To give prominence to the roundabout design, absent what one typically finds like a fountain, which the owner did not want, Two Brothers installed a circular inlay. The finished driveway is slightly crowned so water runs off to the sides. (Continued from page 36) LC DBM Old-fashioned Technology Updated for Construction >> A powder- actuated tool is used in construction to attach materials to hard surfaces, such as those made of concrete or metal. Much like a bullet being fired from a gun, the process uses a chemically created explosion to propel the fasteners, recommended to be made of special heat-treated steel, into the surfaces. With "a high- velocity" type, the explosion acts directly on the fastener. With a "low-velocity" type, the explosion acts on a piston that drives the fastener into the surfaces.
