Natural stone swimming pool coping and patio built by Gappsi in Huntington NY with Scogli di Mare limestone; selected from the Gappsi natural stone collection. The sizes of the Scogli di Mare pavers are randomly mixed in rectangular and square sizes; the Scogli di Mare texture finish is flames and tumbled. The pavers surface consist of natural sea shell fossils exposed by the finishing process. The sealing process begins with pressure washing the entire patio, removing all dirt/debris from the stone surface and in between the joints. Next, Nexgel Techniseal synthetic sand is applied in between the pavers joints and vibrated with a mechanical plate compactor. The plate compactor has rubber rollers to prevent the stones from cracking or scratching. This vibrating process allows the sand to fall in between the joints and density. Then, we clean the pavers with brooms and landscape blowers, to clean the excess sand from the pavers surface and to evenly spread the sand in between the pavers joints. The next step is to wash the pavers by misting water to penetrate the synthetic sand into the paver joints all the way down below the pavers. The sand and water activate a chemical reaction of the pollen that’s in the sand to cause the sand to harden. Finally, the application of the sealer, two parts components urethane dealer, specially formulated for Gappsi, is applied to the pavers surface and the sand joints to prevent stones from staining, extend their life cycle and further enhance their texture, color, and surface.
Hours of construction and design building led the Gapssi group to create a Thursday Goliath 16×37 fiberglass swimming pool with a 3/8 bluestone gravel base that was installed for the under layer of the pool shell for stabilization. Once the pool was adjusted and numerous factors were considered, the pool was then lifted and dropped in place. After installation, Gappsi associates placed solar tubes around the perimeter of the pool to increase support for the concrete slab of the patio base. This fiberglass swimming pool was installed by Gappsi in Lawrence NY 11559, located on the south shore of Nassau County Long Island. Due to the areas high water table the pool needed to be elevated, and many yards of fill were delivered to raise the grade of the property. We faced many challenges installing this fiberglass pool because of its size and weight. The delivery was the main obstacle because due to the size of this pool, 16×37, it was very costly to cross bridges and drive on highways. Due to the size of this magnificent pool we needed 2 police car escorts to the job site.
