Versa Basketball Court Built In Setauket Long Island By GappsiLong Islands Gappsi Team has done it again! No worries about over crowed parks now you can have your very own exclusive recreational center steps away from the comfort of your home. In this photo you see a blue and grey Versa court customized by the homeowner himself. The great thing about the Versa courts is that you have the option to get creative designing your own game lines, layouts, colors and even logos. “Hey, the balls in your court!” What Gappsi Group did specifically was start off with a reinforced concrete base giving a nice even smooth surface to work on as well as rearranging the drainage on the property. Not a one man job! The outdoor court tiles are an interlocking system made from a polyethylene material that is both weather proof and crack resistant with a 25-30 year life expectancy. The Versa tiles have a special shock absorbent attribute that helps relieve stress on the body’s joints and lower back. Gappsi conveniently placed Metal Halide Lights for those long nights whether you’re practicing or finishing off a neighborhood tournament. The Versa tiles are 50% cooler than concrete and asphalt so they are kid friendly if you have interest in doing a children’s playground. Nice and soft for those falls and parents the low maintenance up keep compared to those dirt, sand or wood fiber play areas. Need an indoor court? No problem! The indoor tiles have more of a smooth surface that reflects light giving off a nice shiny appearance. There are a wide variety of other sporting courts and uses for the Versa tiles just call and ask! Stay active Long Island by forfeiting that unused space in your yard or home and let the Gappsi team be in the game!

Gunite Shooting for Swimming Pool after Rebars Installation Roslyn, Nassau County, Long Island NY

Gunite Shooting for Swimming Pool  after Rebars Installation Roslyn, Nassau County, Long Island NYExcavation of this Gunite swimming pool in Roslyn, NY is started by marking up and laying out the pool according to town setbacks. We proceed with framing and establishing the pool shell’s rough height. Then the excavator will dig and shape the hole, preparing it for rebar installation. After the # 4 rebar is installed, creating a cage that outlines what will be the final shape of the Gunite swimming pool. The Gunite cement shell is installed by applying a mix of sand and Portland cement through a pump system which is pushed through a nozzle with the force of compressed air. As the cement comes out from the nozzle, water is sprayed simultaneously to create a bond between the sand and cement, forming the Gunite pool shell. In this particular pool, we also molded an autocover box on the deep end of the pool, and swim out bench  with the same Gunite cement process. On the shallow end of the pool steps were also shaped in Gunite expanding across the width of the pool. At this stage the Gunite pool shell will be left to cure for 28 days, and water will be sprayed on the concrete shell daily to help the shell petrify. Stub plumbing is installed through the Gunite walls for future connection of plumbing pipes. The skimmers are also placed in the pool before Gunite is sprayed, which encases them in concrete. Plumbing for the bottom drains, and pressure relief valve are placed in the floor, in case in the future the pool needs to be emptied and ground hydraulic pressure is under the pool due to high water tables. On top of the pool shell, along the length of the pool a groove is left in the shell for future installation of the Auto Cover track.  The pool shell was constructed 10″ wide for the wall and 8″ wide for the deep end bowl and shallow area floor.
