For liner pools the supporting structure can be made of a wide range of materials. A popular choice is to use block walls that are shuttered with a poured floor in between. This method allows for a much greater variation in wall heights and water depths while providing a smooth constant slope floor. Another option is to use a concrete collar that is poured around each brace which gives the same result with added strength. Hollow agricultural type blocks are used for these types of walls but ordinary cement rendered blockwork may also be used.
During this stage, the physical layout of your pool takes shape in the backyard ground. Using marking paint or wood forms, the tradesmen will plot out the new space and ask you to inspect it before digging begins. This gives you one last chance to make changes, if necessary. Once you’re happy with it, the excavation crew will get to work.
If your pool filter pressure is higher than normal, this usually indicates a dirty or damaged filter. Backwash the filter and recheck the pressure. Similarly, low pressure could be caused by a blockage in the system somewhere before the filter. Be sure to check the skimmers, pump basket and any other places where a blockage may be located. If you are unable to find the source of the issue, call in a professional.
2. Rust on the stator/rotor shaft.
Once the shotcrete has been added and allowed to dry, the plumbing items are fitted. Then the coping material and waterline tiles are laid around the edges of the pool. Coping can be made from concrete, stone or tile, and the options are endless. Once this stage is complete, the pool is ready to be filled with water.
The electrical aspects of the pool are wired up at this point as well. A concrete collar is then poured around each of the wall panels and this adds strength for when the pool is filled with water.
If you’re experiencing this issue, the first thing to do is to shut off the pump and release any pressure within the tank by opening the air relief valve. Once the tank is depressurized, it’s time to take the grid assembly out of the filter tank. Before doing this, be sure to remove any sand or debris that has accumulated in the tank. Next, use a hose to spray down the inside of the grid assembly. Finally, be sure to clean the filter cartridge before installing it into the tank.
Steel fixing is a trade that requires specific skills and knowledge to work with metals. A good steel fixer should be able to read plans, understand the health and safety requirements of working at heights, and know how to use the right tools for each job. They also need to know how to work safely with the different types of reinforcing bars, and how to fasten them correctly so they stay in place while workers walk on them or concrete is being poured.
After the forms are in place, steel reinforcement is added to the walls and floor of the pool using shotcreting or guniting methods. The walls and floor are constructed separately, unless the shotcrete procedure is used in which case they're constructed as a single unit with no gap between them. The concrete will then cure, and the forms will be removed.
Steel Fixing
Many homes in older areas have old leach fields for septic tanks, often placed right where the new pool is going to be. If that is the case, then it is important that the old septic lines are relocated away from the pool area before Shotcrete is put in place to avoid issues with the liner or plumbing.
If you notice excess air bubbles in your pool, the culprit may be a leak in your suction line. Most often, this occurs at the union (threaded connectors between piping) where the filter system connects to your pump. Look at the union and make sure the O-ring is properly seated in its groove and that there’s no debris blocking it from sealing. If there is a leak, it’s time to replace the O-ring and tighten the union.
Check the Pump’s Impeller
For a large, deep crack in your pool’s liner, you’ll need to drain the water until it’s below the cracked area. Then you’ll need to sand the crack and apply a fiberglass layer. The process can take up to a week and requires a lot of work, so this is a repair you should leave to a professional.
Excavation
A clogged impeller is typically the result of improper maintenance. The pool pump basket is designed to keep large debris from reaching the motor and clogging the impeller, but even when the filter is inspected and cleaned regularly, small debris can make it past the basket into the volute and cause problems. This is why it’s important to clean the pump basket weekly (read my article on how to clean a pool pump basket for all the steps).
If the pump was run dry for a long time, or this is the first start up of the season, it’s possible there is rust between the stator and rotor. This can make the pump hard to turn on and is not good for the motor.
Keeping your pool pump and filter clean will help it work to its maximum potential. The pump keeps the water moving and prevents stagnation, while the filter removes debris and contaminants from the pool’s water. Neither function can be neglected, but it is essential to keep them both well-maintained.
If you suspect the impeller is clogged, turn off the power and remove the pump basket. You can use a screwdriver or coat hanger to work the impeller back and forth in the volute. It’s usually fairly easy to feel if the impeller is clogged; it will feel more solid than usual and may be difficult to move at first, but as you work it back and forth you should notice that it gets easier to move. If the shaft seal is leaking it will also be difficult to move, but you should be able to hear and see the escaping water if this is the case.
This stage takes three days to complete. During this time the pressurized concrete is placed and sculpted to your specific design. Our craftsman are expert at handling this heavy equipment and are very skilled in forming a beautiful curved concrete shell that will serve as the foundation for your new pool. At this point any patio materials that you’ve selected will be installed as well.
What Happens During Pool Construction?
Inground pool costs differ depending on the pool's material as well as its shape and size. The total cost of an inground pool ranges from $28,000 to $55,000, or about $50 to $125 per square foot. That's an average cost of $35,000.
It's recommended having a depth fewer than six feet to meet most pool needs. For a family of six to eight people, an 18 foot by 36-foot pool is recommended. This should be sufficient to avoid crowding and allow for the playing of games. Rectangle shaped pools look best for this size.
Pebble finishes, combined with modified cement, last 15+ years. This is the most durable cement based pool finish. Polished marble finishes are an upgrade to standard marble finishes since the reactive cream layer is polished off the pool finish.
Rectangular pools with perfect 90-degree corners have been around for decades. They are ideal for swimming laps or engaging in other types of water exercise. The familiar shape conveys a sense of formality, as well as a sleek, modern feel. For greater design options, rectangles can be modified.
The annual cost to own a pool is $3,000 to $5,000, which includes maintenance, repairs, electricity, and water. The cost to open or close a pool ranges from $300 to $500 on average. Maintenance pricing depends on the size and type of pool you have, and if you upkeep regular maintenance.
