One very important thing to remember: All of the local guys and internet retailers have switched to a product that lasts 5 years on average... no matter what they say the warranty is... their best product lasts 5 years. We are bringing a product that has an average lifespan of 12-14 years, & it costs less. We buy in volume and pass on the cost for a much better product to you. 3 times the life for less money. Sounds like a winner.

Types, shapes and dimensions of swimming pool

in 1971, the standard shape of public swimming pools in the UK was rectangular or L-shaped. Some large pools
had two shallow ends. In L-shaped pools, the long leg can be used for swimming
and the short leg for diving.

However, with the advent of the leisure centre, the shape, size and use of pools
have changed considerably. Figures 1.11–1.13 show examples of public swimming
pools in leisure centres. In these centres, it is usual for the main pool to be freeformed
and incorporate a sloping ‘beach’ and the installation of a wave-making
machine which is switched on for relatively short periods several times a day.
It is emphasised that for competitive swimming,diving and aquatic sports,

the requirements of the ASA (for national events) and FINA (for international events)
must be fully complied with. The requirements mentioned in this book are only a
few of the very detailed requirements laid down by these two organisations. The
following are examples of some of these requirements:

1. For competitive swimming (national events), the water depth in front of the
starting blocks must not be less than 1.80 m and this must extend forward for
a distance of 6.00 m.
2. Stairs and steps must be accommodated outside the pool dimensions, i.e. they
must be recessed.
3. For water polo, the minimum depth of water over the whole playing area must
not be less than 1.80 m; the playing area must not exceed 30 m× 20 m and
must not be less than 20 m×8 m.
4. For life saving certificates, a water depth of 2.0 m is required and this must
extend for a length of 6.00 m over the full width of the pool.

The provision of a diving pit as part of the main pool is deprecated as diving into
a pool in which persons are swimming is unpleasant and can be dangerous. There
are many advantages in having a separate diving pit which is used only for diving.

By having a separate diving pit, swimming and diving events can be held
simultaneously, and the same applies to training.
Pools intended for competitive swimming are normally 25 m or 50 m long with
a width based on a number of swimming lanes, either 2.0 m for national events or
2.5 m for international events. Reference must always be made to the latest edition
of the relevant regulations.

location of public swimming pools

It is not possible to lay down detailed rules for the location of public
swimming pools, but the following are matters which should receive careful
consideration:

1. provision of adequate public transport;

2. provision for adequate car parking;

3. provision of public sewers (foul and surface water), water supply, electricity,
gas and telephone;

4. adequate access for emergency services, fire brigade and ambulance;

5. sub-soil conditions including water table levels, presence of aggressive
chemicals and presence of contaminated ground. This is of particular
importance in view of the alleged shortage in the UK of ‘good building land’,
which in some cases exerts pressure to build on land-fill sites.

Get Your Own Swimming Pool Installed By Professionals

The advantages of swimming pool weigh heavily in favor of having your own swimming pool in your backyard. You can select the swimming pool design, and there are several of these designs available to suit everyone's choice pattern. The pool construction can be entrusted to a professional team from your neck of the woods so that one can have quick execution of task during different phases. The fall in prices has made it convenient for people from different income groups to afford the simple pleasures that a swimming pool gives you. A pool can entertain and help maintain your health as well.


Doctors are unanimous in their approval of swimming as the cardiovascular exercise that is friendly to the body, so much so that people with arthritis and other serious disabilities are advised to swim rather than walk or jog. When you are struggling with the choice of swimming pool design first of all you have to resolve the selection between vinyl pools and Gunite concrete pools.
A vinyl pool is relatively free of algae and other bacteria. It is also easier to clean and therefore low on maintenance as well besides being easier to winterize too. Vinyl pools come with their individual designs and you need not spend money on coloring your pool. These pools are also flexible and therefore do not spring leaks easily. Being stain resistant you will find stains easy to wipe off the smooth surface. Finally, vinyl pools are easier to install compared to the concrete ground pools. Vinyl pool construction requires excavation, installation of the pool walls and gunite pool floor followed by pool deck installation. Finally, the liner is installed, equipment started and the wood work and landscaping completed.

In the case of Gunite concrete pool construction the excavation is followed by the construction of pool walls, steps and benches. Concrete at high pressure is next applied through a hydraulic pump and stone coping, tile and plaster are installed on the concrete pool shell. Finally, the deck is installed, landscaping completed and water added to the pool.
You have total freedom in swimming pool design in terms of shape, landscape, water features and carpentry. The shapes can be from among Heritage, Victorian and Muskoka as well as Oval, Trinidad, Sapphire and Vermont or Copenhagen and Mountain Lake. You can have water plunging over a natural stone waterfall and stone coping or pattern borders, stone walkways and fiberglass or custom concrete spas besides cedar cabanas and fencing, gazebos, pergolas and arbors. The swimming pool professionals are there to convert your dream pool into reality.

Helpful Tips for Swimming Beginners

Swimming is one of the most-loved sports both by kids and adults. Teaching kids how to swim at a very young age is an advantage because they will not have a hard time learning how to swim when they reach old age. However, this doesn’t mean that adults can no longer learn how to swim. 

Sometimes the fear of submerging to the water hinders kids and even adults from learning the right ways of swimming. Apart from that there are also some factors that affects the learning of the swimming beginners. Thus, it is necessary to take in mind the helpful tips for beginners so they can overcome their fear and learn the proper ways of swimming.

1. Make yourself comfortable in the water

A lot of people are afraid of the pool water and this fear should be overcome first.  Start it by standing in the shallow end of the pool while holding the pool wall. Try to squat leading your chin close to the water and practice breathing and relaxing. Once you feel relaxed, try to go deeper under the water while holding your breath longer. If you can open your eyes, open it so you can see the underwater surroundings. Remember to just relax so you can hold your breath a little longer. 

2. Try to exhale through your mouth

One thing you should know is that you have to exhale not in your nose but through your mouth. Exhaling through the nose can cause water to enter your nose which is not a good thing in swimming. Take a right amount of oxygen, close your mouth and make sure not to breathe in your nose. Squat and submerge under the water and slowly try to exhale through your mouth creating bubbles. This is necessary to keep yourself relaxed underwater and not be uptight while holding your breath.

3. Make yourself float in the water

After you learned how to submerge properly under the water, the next thing you need to do is to learn how to float in the water. Squat under the water, hold your breath and let yourself float. Remember that no matter what you do, you will still float in the water whether you like it or not. So, this step will be very easy for everyone. 

Once you felt like floating, lay on the water facing down and stretch your legs and arms with your palms down. Relax and hold your breath properly and exhale through your mouth just like what you did on the second step. Your body should be laying horizontally in the water. Once you are ready to stand up, move your arms above your head and down to your hips keeping your arms straight. Now, you can stand properly after floating in the water.

Mastering these steps is necessary so it will be easy for your to learn the next steps especially the basic swimming strokes. Always remember that relaxation, concentration and focus are important skills you should posses to be a good swimmer in the future.

Properties of building materials swimming pools

1-Portland cements
It is made by burning at high temperature a mixture of chalk and clay in a rotary
kiln. The clinker is ground and gypsum (calcium sulphate) is added to control the
set. British Standard BS 12 limits the amount of sulphur (expressed as SO3) to
3.5%. The fact that Portland cement contains sulphate is important when
investigating the possibility of sulphate attack on concrete or mortar which is
discussed

The addition of water to the cement results in a complex reaction accompanied
by the evolution of heat.
Revised British Standards for cements were published in 1996. The new
designations for Portland cements likely to be used for the construction of swimming
pools and external works are as follows:

Portland cement class 42.5 to BS 12 1996 (CEM 1);
Portland cement class 52.5 to BS 12 1996;
Portland cement class 42.5R to BS 12 1996;
Sulphate-resisting Portland cement class 42.5 to BS 4027 1996;
Portland Masonry cement to BS 5224 1995, ENV 413.1.
The letter R denotes high early strength.
The revisions were mainly concerned with methods of test and terminology
and were intended to agree with the European Standard for cement, ENV 197–1.
Minor changes in composition were also introduced.

The principal characteristics of Portland cement are:
1. A very fine powder, particle size 1–50 microns (1 micron equals 0.0001 mm).

2. The paste (cement and water) is highly alkaline, having a pH of about 13.5.
The high alkalinity is relevant to the protection of steel reinforcement, and
also to the occurrence of alkali-aggregate reaction. The interaction betweenalkalis

in the cement and certain types of silicious aggregates is discussed

3. The setting time (initial and final) is in the range of 45 minutes to 10 hours.

4. The compounds which are principally responsible for the cementing action of
the cement paste are mainly the calcium silicates (the C2S and the C3S).

5. It is the hydration products of the cement which, other things being equal,
determine the strength of the concrete/mortar. The hydration products are very
complex chemical compounds. The principal compounds are calcium silicate
gel, calcium hydroxide (about 20%) and tricalcium aluminate hydrate. The
calcium hydroxide (Ca(OH)2) is liberated by the hydrolysis of the calcium
silicates. The various hydration products hydrate at different rates, but the
hydration is rapid to start with and then slows down.

6. The three major factors which influence the rate of gain of strength are the
chemical composition, the fineness, and the temperature of the hydrating mix.
With modern cements, the increase in strength after the first 28 days is likely
to be very small and can generally be ignored.

7. The amount of water in the mix (usually referred to as the water/cement ratio,
w/c) is a vital factor in determining the strength, permeability, absorption and
durability of the concrete/mortar. Generally, other factors being equal, the
higher the water/cement ratio the lower the strength and the higher the
permeability and absorption. This is why it is often necessary to use a plasticizer
in the mix when high quality concrete is required.

8. Due to its high alkalinity, Portland cement is very vulnerable to attack by
acids. The reaction between the cement and the acid takes place immediately
the two are in contact.
