WHY NOT A CONCRETE POOL

Once cracked never 100% repairable – costly to repair

Not suitable for all ground surfaces

Maintenance cost very high (use lots of expensive chemicals) takes longer to clean especially brushing

Pool temperature lower because of concrete walls

A Concrete pool is not flexible, steelwork rust, lost strength yearly! Cannot absorb ground movement

Needs regular acid washing and resurfacing either with marbelite or a pool paint that don’t last

Pool surface stains easily and black and green algae can grow into the pool surface

Installation of a concrete pool is 4 times longer

Concrete pools cannot be relocated and therefore not old if not needed

Surface of a concrete pool is not smooth it is rough and causes damage to your skin especially children’s feet and toes

Concrete pools are expensive to build and maintain


BASIC SPECIFICATIONS ON THE MANUFACTURING OF A FIBREGLASS POOL SHELL & EQUIPMENT

GELCOAT LAYER
CORROSION BARRIER
STRUCTURAL LAMINATION
STIFFENING RIBS
BUFFER ZONE
OUTER SURFACE (SEALER COAT)

The basic laminate specification consists of a gel coat layer, a corrosion barrier, a structural lamination, stiffening ribs, a buffer zone and an outer surface sealer.

Gel coat layer:
This is the surface which is in contact with the water. The blue layer seen by the eye is in fact a Neo Pentol Glycol Resin (NPG) which is applied at a rate of 450-500g per m². The NPG Gel coat is also available in a variety of exciting different colors as well as chip colors.

Corrosion Barrier:
A heat and chemical resistant vinyl ester rich layer is applied immediately behind the gel coat using a finely chopped fibre creating an incredibly strong corrosion barrier eliminating any chance of blisters, osmosis or degradation.

Structural Lamination:
This is the main body of the pool shell as it contributes to approx. 80% of the total strength especially in the following structural areas:

  1. Top rim (perimeter) of pool
  2. Walls
  3. Coving
  4. Floor
  5. Step area

The structural lamination is applied by hand with rollers and structural laminating resin. The laminate thickness varies between 5 – 16 mm thick, depending on the size of the pool and where the measurements are taken, e.g. floor, rim, etc.

Stiffening ribs (rowen):
A core material used in conjunction with fiberglass matting is laminated around the top perimeter of a pool as well as other strategic areas which enhances overall aridity and stiffness of the pool, during transport and installation.


Buffer zone:
A polyethylene core material is used in conjunction with fiberglass laminate which is positioned in strategic areas on the sides of the pool, offering protection during installation and transport.

Outer surface (sealer coat):
This is a black alkaline resistant coat which seals the fiberglass laminate from alkaline attack from behind, e.g. soils, acid, cement, etc.


INSTALLING YOUR OWN FIBERGLASS POOL

HOW TO GO ABOUT:
Choose a site for your pool, it must be as level as possible as you do not want the extra expense of building retained walls.
Also avoid rocky terrain, as digging here may require hiring of expensive machines. Make sure your pool will be clear of existing sewer and water pipelines, or buried service cables, it can be moved but at a price.

Check the surroundings to determine how the pool shell can be delivered to the site also keep in mind that the excavated soil must go somewhere, so find a suitable dumping spot or cart it away.

Contact the local municipality to find out if you need special permission for a pool on your property, and what plans must be submitted.

Mark out the exact pool shape on the prepared site, then allow a further 250-500mm all around for the over excavation. Knock in 4 pegs roughly as per diagram 1. then with a dumpy level or a long clear plastic pipe filled with water, find and mark these pegs with paint the datum, which will be the top of the fiberglass pool shell when it is fully installed.

Excavate the pool area up to the over excavate mark and about 100mm deeper than the required depth, as given by the manufacturer of the selected model.
Depth is always measured vertically down from a line stretched across the pool area between 2 datum marks. (See diagram 2)

Thoroughly compact the floor of the excavation and place a number of bricks flat down at the bottom. And exactly at the required depth as measured from the line between the two front and rear datum marks. Add a bed of clear river or building sand, the carefully compact and screed the sand to be level with the top of the bricks. The bricks can now be removed, the cavities filled with sand, and the area compacted. When placing the shell into position on the screed sand, ensure the datum pegs line up with the top of the pool shell.

Minor adjustments can then be made by again using the plastic pipe filled with water to check the exact levels against the bottom of the mosaic trim.
Now comes the important task of back filling, but start by adding water to a depth of about 300m at the deep end of the pool. Recheck the shell levels against the bottom of the mosaic trim. If everything looks fine then start caulking clean sand under by hand under the bottom curve all around the outside of the pool ( See diagram 3)

Brace the sides along the top of the rectangular pool using timber. Then start back filling with clean river or building sand, working carefully up to about 300mm below the new level. Continue this back filling process to just below the spot where the plumbing fittings are connected to the fiberglass shell, checking levels as you progress.

NOTE: a) As soon as the pool is level and well secured in the hole, use a small angle grinder with a masonary disk to cut out the section for the skimmer box and any optional light holes. Install the box and lights using clear silicone sealant. All electrical connections must be done by a qualified electrician.
b) In low-lying areas with a high water table, it is advisable to back fill with a mix of 1:8 cement and dry sand.
Complete the back filling to the top of the horizontal reinforcing rib along the outer edge of the fiberglass shell. Now fill the pool with water before the final compacting of the back fill can done. Using a mix of 1:3:6 cement, stone and sand, cast a concrete slab to bridge the back fill, allowing for sufficient slope away from the pool edge (See diagram 4). The concrete must be left for about a week to cure. Prepare the ground around the pool for the paved surround that can also be a D.I.Y project or left for a paving contractor.


QUICK TIPS ON CLEANING A POOL JUST AFTER INSTALLATION

 

First brush the surface of the pool with a nylon brush to loosen all cement particles.

Remove loose stone and cement pieces on the floor.
Add one packet of alum powder (aqua sheen) to the pool water, leave pump off and leave for 24 hours.

After 24 hours slowly on waste suck powder off floor and clean waste basket from time to time to make sure you maintain full suction at all times, fill pool with fresh water while cleaning is in progress (stops if pool level drops too low and wait until full to continue)

Most important, after alum powder is applied to pool water it must be left for 24 hours.

After the water and surface is cleaned manually add two to three cups of chlorine depending on the size of the pool chlorine must be added and a half cup of pool acid.

Fill pool to correct level. Plug automatic pool cleaner in

Correct Ph level fiberglass pools 7.0
Never use soda ash in a fiberglass pool


MAINTENANCE ON A SWIMMING POOL

Three golden rules to maintain a healthy blue swimming pool

  1. Correct water balances
  2. Correct filtration
  3. Correct circulation

 

Water balance
Ph balance of a fiberglass pool is 7.0 (marble pools 7.2 – 7.4)
Chlorine 1 – 3 ppm
Alkalinity 80 – 120 ppm
Calcium 250 ppm

Correct filtration

Correct filtration is achieved by the correct size and pump, clean filter habits (back wash and clean filter sand) Time setting for the filtration period of at least 12 hours in summer day time from 6 am to 6 pm.
Filter sand must changed after 5 years, filter sand must be cleaned in the beginning of every swimming season by using filter cleaning liquid and a open back wash.

Correct circulation

Make sure that the aim flow and the weir are installed in the correct places so no dead spots cure, for circulation. No suction leaks for maximum circulation.

Recommended chemicals to use

Month mate pool floater sufficient for fiberglass pools
Salt chlorinator
Pool acid
HTH chlorine


TROUBLE SHOOTING AND THINGS TO REMEMBER

Q: Water after cleaning still milky?
A: Back wash, rinse, put in a gel block

Q: Automatic pool cleaner stops and goes?
A: Check for suction leak, check filter and clean, check of cleaners “airways” are clean, check if inner weir lid is correctly fitted

Q: Pump does not work?
A: Make sure electrical wiring is fitted correctly; timer is set on auto and set correctly

Q: Green algae on pool surface?
A: Shock treatment and brush

Q: Are fiberglass pools stronger than conventional concrete or gunite pools?
A: The key phrase here is “flexible strength”. Only factory pre-moulded fiberglass reinforced pools successfully combine strength and flexibility to allow the option of placing your pool in almost any soil an also in ground which is not suitable for conventional pools.

Q: Can fiberglass pools “pop out” of the ground?
A: Any pool or underground sited structure such as a storage tank can pop out of the ground. However in the unlikely event of “pop out”, the flexible strength of a fiberglass pool ensures that there is no irreparable damage, which is not the case with most other types of pools.
A pool must not be left empty and professional advice/service should be obtained before you empty your pool.

Q: Is a flexible pool leak proof?
A: If a pool is pre-moulded in a factory, such a pool will be leak proof. A factory manufactured fiberglass pool does not have any seams or joints, which means that it is ultra strong and cannot leak. This is the assurance any reputable fiberglass pool company manufacturer is prepared to give.

Q: Is a fiberglass pool more costly to maintain and keep clean?
A: On the contrary, a pre-moulded fiberglass pool costs significantly less to clean and maintain. The smooth non porous surface of a fiberglass pool makes routine cleaning a quick and effortless operation.

Q: What about algae and staining?
A: The smooth non porous surface of a fiberglass pool eliminates algae infestation and precludes permanent stains.

Q: If a pre-moulded fiberglass pool is smooth, is it not slippery?
A: A non-slip finish introduced at the manufacturing stage eliminates the danger of slipping or skidding on a fiberglass pool.

 

Q: Does it take longer to install?
A: A concrete pool takes four times longer to install

Remember!

When changing filter sand, close brewer pipe, put lid screws in holes before adding the sand, open the brewer pipe after filling. Back wash and rinse before filtering.

When a filter system is installed (pump & filter) it must be on the same level as the water level of the pool to be working without hassle.

Suction leaks cause the automatic cleaner to stop and go very slowly. The reason 9 out of 10 is because air that leaks through the fitting and pipe connection at the weir (start there!) suction leaks only acquire from the head of the automatic pool cleaner to the front part of the pump.
Tests for a leak – put the control key (multiport valve) by pass (circulation) see if it works or not (no block in the filter)
Go to the weir, block the hole with your hand for 10 seconds, see if bubbles came out of the aim flow, if so there is a suction leak, and then repair pipes. If no bubbles see if pipe is not blocked, suction pipes and the return. If not replace pump.

Water treatment

Test water once a week for ph level, backwash and rinse once a week. Backwash for 2 minutes and rinse for 30 seconds or until inspection glass is clear.
Top pool with water, keep chlorine level 1 – 3 ppm, Ph 7.0 fiberglass or 7.2 – 7.4 marblite.

Function of a filter

The top port – multiport valve can turn any position, clockwise or anti-clockwise, but only when pump is off.
Filter: is for the normal filtering of water, to trap dirt and give clarity to the pool water.
Close function: to block air to the system when you need to open the lid of the pool pump.
Backwash function: to clean the filter sand at least once a week or when suction strength drops.
Rinse: is to clear milky water after backwash, until inspection glass is clear
By pass: is when the water is flowing directly from the weir to the aim flow skipping the filter, used when liquid chemicals are applied in the pool water.

Waste: this function also bypasses the filter and through water directly from the pool to the draining pipe of the pool, used when pool water is cleaned, when there is sand, etc. in pool.


BENEFITS OF HAVING A POOL

Adds value to your property

Sells your house faster

Most relaxing and refreshing
 
Excellent exercise

Health

Entertainment for children

Compliant to your house and garden

 

Choosing the size of a pool

 

After years of pool owners the presumption changes from larger pools to smaller pools.

This is due to the fact that bigger pools are colder, cost more in chemicals and water, and smaller pools with fewer costs are just as much fun.

A small pool looks just as good in a garden and does not take up much space. Why spend a fortune to maintain a large pool. The shape of a pool is more important than the size when it comes to disusing making.
