A larger pool is desired, but the existing concrete pool should or must be maintained. For many years, VPS swimming pools have been installed in conjunction with concrete swimming pools, for example, to execute an enlargement or the addition of an outdoor pool with a swim through channel. Thanks to a specially developed connection method, these two basin variants can be stably and permanently sealed together. Surface and gutter design can be matched to the existing ones, so that it appears as one piece. We want to help you plan this.
