Depending on the size of the building block sometimes the pool must be installed prior to house construction commencing. When it comes to fibreglass pools this also means the pool must be immediately filled with water in order to settle and hold the shell to the ground. Due to hazards and risks both to construction workers on site as well as your new pool, a higher level of protection may be required. Pool construction covers can be great peace of mind knowing your new pool investment is protected while workers are on site.
