If you want to make an ornamental pool or pond to your garden, what can be more joyful than making your own designing your own pool? PVC liner is the liner of your pond or ornamental pool. You can also design your own pond and enjoy the view of fish swimming in a natural environment or plants. The first thing to do in building your own ornamental pool is to find the right place in your garden and to dig a leakproof hole to this place. This leakproof feature is provided by the liners. These liners must be resistant to tearing out, corrosion, decaying and to microbial activities. Only covering the pond with regular plastic will create problems in the long term.
