The experts at Advanced Pool Coatings have been installing fiberglass coatings over vinyl liner pools for over 30 years. You can read more at: http://www.advancedpoolcoatings.com.
No. An older (possibly better) type of Fiberglass pool was constructed in this manner, with a concrete/Gunnite/Marcite trowled bottom and Fiberglass panels at the side of the pool. Panels are caulked together along vertical joints. Actually not a bad deal, but caulked joints must be maintained. Once the concrete starts showing through at the bottom of the pool, its time to drain and resurface. Bottom of pool should be acid washed every 3-5 years to keep it sparkling and remove mold, mildew, stains. If bottom surface is chipping off, its getting close to time to resurface bottom of pool. Bottom is treated just like any concrete/gunite/Marcite pool surface. Sides are simply brushed, caulked in timely manner.
The sides of a canal lock is made from bricks or concrete.
No!!! Under no circumstances should you drain a fiberglass in-ground pool. Unlike the standard in-ground pool, the fiberglass pool base is unreinforced concrete or other hard surface material that was applied directly to the soil in a thin layer. It is only there to allow the fiberglass to be sprayed on and form a hard shell. The weight of the water is what holds the fiberglass in place. If you drain the pool without refilling it immediately, you will allow external ground pressures and/or ground water to buckle the sides or bottom and you will have the fiberglass completely redone.
Yes it can leak and will if not installed properly. If it does there is a method and product to deal with it. SEKAFLEX is sealent used with both concrete and fiberglass with 100% satisfaction. If was not used with the installation I would be supprised. Take 4" grider with a diamond blade and score the concret where it meets the fiberglass and fill with sekaflex. Done!
Theoreticaly Yes
Steel re-inforcing in concrete should always be placed 1/3 of the depth from the bottom. A 6" thick slab would have the steel placed 2" off the bottom.
Concrete backer board is usually used as an under layment for ceramic tile. It can be used on walls, floors or countertops. It has a solid core and is faced on both sides with fiberglass. It's an ideal under layment for wet areas like shower walls and bathtub surrounds, and is typically mold resitant.

Purchasing a pool is a large investment for any homeowner. There are several different types of inground pools available, so selecting the right one can be a challenge. Currently, fiberglass, concrete and vinyl liner inground pools are being sold. Comparing each type can make buying a pool much simpler. Fiberglass inground pools are a great choice for pool buyers. They are pre-constructed at a factory and shipped to the desired location in one piece. A customer simply selects their preferred size and shape from a catalog. Fiberglass pools are typically the most expensive pool on the market, but they last the longest. In the long run, a fiberglass pool will require less repair and fewer chemicals than other pool types. It usually takes only a few weeks to install a fiberglass pool from start to finish. The inside of fiberglass pools is smooth to the touch. For homeowners that desire more freedom designing their pool, then a concrete one would be the best option. Concrete inground pools are currently the most popular on the market. They are custom created by pool builders, which is great for customers who have a difficult yard shape. Concrete is usually less expensive than fiberglass, but requires more care over the years. Unlike fiberglass, a concrete pool is built in stages, so the construction time tends to be longer, usually one to three months. These pools come with a wide variety of finishes, from rough plaster to smooth tile. Less popular are vinyl liner inground pools. These pools are typically sold to the consumer in a kit form and put together by the owner. First, the ground must be excavated to fit the pool, and then it is placed inside. The sides of vinyl liner pools are constructed from steel. Once erected, they will be permanently supported by concrete. A vinyl liner is then spread over the sides and bottom. These pools are very popular in parts of the country where there are cold winters, as they can be easily drained and covered until the weather warms back up. Swimmers enjoy the smooth surface of the liner, but it can accrue more damage than other pools types.
