Pool orientation


In small gardens or backyards, we do not always have the opportunity to choose the location and orientation of our future pool. On the other hand, in many other cases the homeowner can choose among different places in order to build the leisure space.


When thinking about building a new pool many questions may arise regarding the pool orientation. Do I have to place it where there is more sunlight?  Should I keep it far away from trees and plants so that the leaves do not fall inside? Will my pool get dirtier if I do not consider the prevailing wind directions?

The correct answer is that both sun and wind are an important factor when selecting the perfect spot for your pool. So, it should be a sunny spot, far from trees and plants and facing towards the prevailing wind direction of the specific loaction.

Let the sunshine in!

Considering the amount of sunlight and shade is critical to choose your pool orientation. Not only should you consider how many hours of sunlight and at what time of the day but also how the house itself or the surrounding landscape elements will cast shadow onto the pool.

Do not forget that after or before diving into your pool, you will want to lie down on the pool deck in order to get a tan. So, try to get as much sunlight as posible. The colour and brightness of the water will also look differently. The less sun the pool gets, the less bright will its colour shine. If you have small children or a sensitive skin, you may also need to consider providing some shading with a sunshade or a pergola, for example.

Branches and leaves

Plants and trees are a fantastic element in any garden because they cool the environment, but when there is also a pool they can be hassle. Think about what kind of plantings you would like to have around your pool and choose the ones with the minimal leaf drop. This way you’ll have a low-maintenance relationship with your pool. Consulting a good landscape gardener will always be a good help.

Where to place the skimmers?

And last but not least, we have to think about where to place the skimmers because it will save us a lot of maintenance time. Skimmers helps to clean the pool water by capturing floating dirt such as flowers, leaves or dead insects. They should also face the predominating wind direction and the eye ball jets just in front of it. If it’s a rectangular pool, they should be placed on the small walls. This way we’ll keep dirt from building up on the corners of the bottom and on the floating line. Do not protect the skimmers from the wind!

We understand that sometimes there are limited options because of the existing building or the space available for the new pool.  Of course the optimal situation is when you are designing your new house and you can start the building of the pool from zero. Anyway, we recommend you contacting a reliable pool builder who will help you with this important decision.

How to clean the pool after winter

How to clean the pool after winter

How to clean the pool after winter


Spring has finally arrived ! Days start getting longer and temperatures are more pleasant. Warm weather will soon be here. 


We look forward to buying sunscreen and to looking for our swimmsuit in the wardrobe. The first thing that we have to do before we can go bathing is to clean the pool after winter. We have to start thinking about getting our pool ready for summer when the outdoor temperature is about 20°C (68 °F). 

Another hint for timing the spring cleaning of your pool is when the water temperature is around 12°C (54 °F).  It depends on how sensitive to cold you are, but generally speaking, it’s then that it’s time to get the pool in operation again.

In case you don’t have time or you just don’t feel like doing it on your own, you can always commission a pool professional to clean the pool after winter. Pool professionals are either pool builders or gardeners with knowledge of swimming pools. Otherwise simply ask at your swimming pool supply store where you buy the pool chemicals and accessories. The last mentioned can clean your pool after winter for you or just give you some advice on how to do it because it’s quite easy.

When is my pool ready for swimming?

As aforementioned it’s time to get your pool ready for swimming when water reaches 12 °C (54 °F).

The pool needs to be prepared for winter when the water temperature is below 12 °C (54 °F). And at all events before freezing weather starts. The main steps are lowering the water level in the pool and shocking the pool with chlorine (chlorine level up to 0.8 mg/l). The filter system should run as long as possible. Afterwards remove the equipment from the pool and keep it in a dry place. Finally cover the pool with a winter cover.

If you prepared your pool for the hibernation correctly, then you’ll have to work less in spring in order to get it ready for summer.

You shouldn’t use your swimming pool during the hibernation. Even if the water level is below the skimmer level, the water quality isn’t safe for swimming. Never empty your pool during winter because it will prevent the foundation from getting damaged. Apart from this, water will protect your RENOLIT ALKORPLAN pool lining.

Steps to clean the pool after winter

1. Remove the winter cover

First of all remove the winter cover. Clean it by using a garden hose, let it dry and store it away in a dry place until the swim season is over. If you didn’t use a cover during winter, then the water will definitely be very dirty and you’ll have to clean the waterline properly.

2. Assemble the pool enclosure or pool blind

If you have a pool enclosure or a pool blind, now it’s time to clean it and to assemble it.

3. Completely drain the pool

This question always throws up controversy because many pool owners replace the pool water every 2 to 3 years. Water is after all a precious resource. Nonetheless, we recommend replacing the pool water after winter for hygiene and in order to spring-clean the pool liner.

4. Spring-clean the pool

Clean it immediately after draining it so that the dirt on the lining doesn’t get dry. With the aid of a garden hose gently scrub the walls. But not too vigorously, so that the reinforced pool membrane doesn’t get damaged. Lastly, rinse off with clear water.

5. Do not spray any pool algaecide

If any, only without copper. Elevated copper levels in water often cause discoloration on the lining.

6. Inspect the lighting, seals and filter
7. Fill the pool with fresh water

Close the drain valves (not the skimmer ones) and fill the pool with fresh water to the middle of the skimmer opening.

8. Turn the filter pump on

Clean the filter pump and turn it on when the water level has reached the middle of the skimmer.

9. Check the pH level

Check the pH level so that the pool chemicals perform in an optimal way. It should be around 7.2 -7.6. Use pH Minus or Plus to adjust the pH level.

10. Add the pool care products

In case you didn’t replace the pool water completely, it’s advisable to shock the pool to keep your chlorine level up and prevent algae growth.

That was it for „spring-cleaning the pool“. It wasn’t that bad after all, was it? So now your RENOLIT RENOLIT ALKORPLAN pool is ready for the summer. Download the checklist so that you don’t forget any important step before the swimming season starts. We wish you lots of swimming fun!

No more pool water leaks with RENOLIT ALKORPLAN

No more pool water leaks with RENOLIT ALKORPLAN

Let’s talk about one of the most common worries for all pool owners: LEAKS!
RENOLIT ALKORPLAN guarantees complete impermeability of its reinforced membranes for 10 years, in writing. Did you know that, every year, many owners of pools built with finishing techniques other than our reinforced membranes contact us or our certified installers to definitively solve the impermeability problems of their pools? Pool infiltrations appear when the impermeability is not guaranteed.

RENOLIT ALKORPLAN is the guaranteed waterproofing for pools

The RENOLIT ALKORPLAN reinforced membrane (membrane 150/100) is the perfect solution for renovating all kinds of pools. The reform of a pool with the reinforced membrane also enables the existing structure to be reused to the maximum without having to make radical changes and allowing great savings. Pool leaks entail an economic cost, a correlative environmental impact in the water consumption and, above all, not solving the causes of the infiltration problems in a pool can cause serious deterioration of the structure and the underlying parts.

Cause of infiltrations in pools:
The origin of leaks in a pool can be discovered in the following way:
– If they are in the hydraulic installation it is very easy to detect them by simply building up the pressure in the installation.
– If they are in the shell, they are much more difficult to identify. To discover a leak, a test must be done putting the installation under pressure.

Construction Systems
The construction systems are different, each one with its own peculiarities and specific guarantees; it is necessary to assess not only what the builder offers, but also the characteristics of the product itself.
Below is a summary of the most used structures on the market.

  • Reinforced concrete pool
    This is completely made from reinforced concrete; the bottom and walls are concrete. It guarantees great solidity, but it must be made extremely carefully, its perfection depends a lot of the builder’s experience. The reinforced concrete structure allows any shape to be made and takes all kinds of finishes. The time and costs are generally high compared to other systems. The builder gives the guarantee.
  • Pools with metal panels
    This type of pool is made preparing the bottom and the panels are mounted around its perimeter, which can be from different types of metal. Assembly is quick and easy and creates an ideal structure for using the RENOLIT ALKORPLAN liner immediately. Panels can be transported and assembled easily and are supported by pressure-moulded metal buttresses that give the structure resistance to the hydrostatic pressure of the water and the surrounding land. The panels have an optimum price-quality ratio which can vary depending on the metal used: galvanised sheet, aluminium and stainless steel alloy (the last being very resistant to corrosion). Guarantees for the panels vary between 10 and 30 years.
  •  Pool with polystyrene enclosures
    This structure is also defined as disposable.
    This is made with hollow blocks of high-density polystyrene that, supported on the concrete base form the perimeter wall of the shell. Of fast execution, after installing them they are reinforced with steel bars and, next, are filled with concrete and so the pool will look like that of reinforced concrete. Expanded polystyrene (EPS), being insulating, maintains the temperature of the water for a long time. The internal walls are levelled out or protected with a smooth mat enabling the application of the RENOLIT ALKORPLAN liner. Panel guarantees (being a product that will get damaged over time) must be checked with the supplier.

The range of RENOLIT ALKORPLAN reinforced PVC guarantees impermeability and can give your pool a second life, offering different colours, designs and textures that spruce up the pool. Get rid of your fear of infiltrations and begin again with complete lasting certainty like day one!

Practical RENOLIT ALKORPLAN advice for pool water treatment

Practical RENOLIT ALKORPLAN advice for pool water treatment

You have chosen a product from the RENOLIT ALKORPLAN range and your pool is beautiful, but now, having filled it up, it is time to deal with water treatment. When the water is perfectly treated, not only does it look good, but it is also healthy and safe. So, what do you have to do?

First, obviously, the installation and correct sizing of all the parts is very important. In an efficient installation, all the pool water circulates in very little time, a maximum of 5 hours. If this is not the case, we suggest making the relevant changes. But meeting this requirement does not guarantee that the water is perfect, both aesthetically and bacteriologically, it is also necessary to periodically check the pH value and use water from the aqueduct to fill it up.

It is essential to carry out constant and necessary treatment to avoid the formation of bacteria, microorganisms and algae that could lead to having to treat the water with massive amounts of expensive chemical products. The ideal pH value is more or less 7. If it is lower, it means the water is too acidic and can corrode the metal parts and look for basic elements to regulate itself. If the value is higher, the water is called basic and offers ideal conditions for developing algae, microorganisms and chalky formations. It will also look murky and not transparent. If the pH value is too high we have basic water and to recover it we use pH Minus, an acidic product; however, to make the water less acidic, a basic product is used called pH Plus. For normal water treatment Trichloroisocyanuric acid is used, generally in tablets, free chlorine must have a value between 0.6 and 1.5 ppm. The acid tablets are placed in the Skimmer or in friction dissolving devices. With an electrolysis system, we recommend an automatic method with probes, less maintenance needs and more time for you.

One of the natural properties of chlorine is to dissolve: it tends to oxidize converting the organic substances in the water into chlorides which the ultraviolet rays of the sun destroy. To limit the reaction caused by the UV, cyanuric acid is added that, as well as protecting the chlorine from the ultraviolet rays, it captures the excess chlorine to later release it little by little when necessary.
