Membrapol Pool System: Swimming Pool Waterproofing and Protection in Fuerteventura
Proper swimming pool waterproofing is essential to ensure long-term durability, prevent water leaks and preserve the structural integrity of the pool. In Fuerteventura, where outdoor swimming pools are exposed to strong sunlight, temperature variations and, in coastal areas, salty marine environments, choosing suitable protective materials is particularly important.
Among the technical solutions available is Membrapol Pool System, a system designed for waterproofing and protecting concrete swimming pools and water containment structures, incorporating specialist products such as Membrapol 900 TIX and Membrapol 200 PU.
In this guide, we examine the characteristics of the system, the specific functions of its components and the factors to consider before building, waterproofing or renovating a swimming pool in Fuerteventura.
Why Is Swimming Pool Waterproofing Important?
Swimming pools operate under demanding conditions compared with many other building structures.
Continuous contact with water, hydrostatic pressure, chemicals used for water treatment and temperature fluctuations can gradually affect construction materials.
When waterproofing is inadequate, deteriorated or discontinuous, several problems may occur:
-
Water leaks caused by cracks, deteriorated joints or pipe penetrations.
-
Water infiltration into surrounding ground or adjacent structures.
-
Concrete deterioration resulting from water entering vulnerable areas.
-
Coating failure or delamination caused by inadequate adhesion.
-
Increased water consumption due to frequent refilling.
-
Higher maintenance costs associated with repairs and restoration.
However, not every swimming pool water loss problem is caused by defective waterproofing.
Before choosing a repair method, it is important to determine whether the issue originates from the concrete shell, plumbing connections, fittings or filtration system.
A proper diagnosis helps identify the underlying cause and prevents unnecessary repairs.
What Is Membrapol Pool System?
Membrapol Pool System is a technical system developed for waterproofing and protecting structures designed to contain water, particularly concrete swimming pools and tanks.
It combines products with different functions, which must be selected and applied according to the condition of the substrate and the manufacturer's technical specifications.
Two relevant products are:
-
Membrapol 900 TIX: a three-component product used for substrate preparation and surface levelling, formulated with epoxy resins and reactive hydraulic binders.
-
Membrapol 200 PU: a two-component polyurethane protective finish designed to provide resistance to water, ultraviolet radiation and various environmental conditions.
These products perform different roles within the treatment system.
It is important to understand that waterproofing a swimming pool involves more than simply applying water-resistant paint.
The effectiveness of the intervention also depends on the condition of the concrete, the treatment of cracks and joints, and the compatibility of the materials used.
Membrapol 900 TIX: Preparing Concrete Surfaces
Membrapol 900 TIX is a three-component product based on epoxy resins and reactive hydraulic binders, designed for preparing substrates that may have irregularities or certain moisture conditions.
Surface preparation is one of the most important stages of any waterproofing project.
Dust, poorly bonded materials, existing coating residues and surface defects can compromise the adhesion and performance of subsequent protective layers.
What Are the Main Characteristics of Membrapol 900 TIX?
According to the manufacturer's product information, its properties include:
-
Good adhesion to common construction materials, including concrete, natural stone, brick and cement blocks.
-
Suitability for certain damp substrates, subject to the specified application conditions.
-
Surface levelling and preparation capabilities.
-
Application to vertical surfaces and complex geometries.
-
Resistance to specified moisture and water exposure conditions.
These characteristics make it a product worth considering when preparing concrete swimming pool surfaces for subsequent treatments.
However, a damp substrate must not be confused with a surface affected by active water infiltration or uncontrolled hydrostatic pressure.
Such conditions require specific investigation and appropriate treatment before protective products are applied.
Cracks, damaged joints and structural movement must also be assessed and addressed beforehand.
Membrapol 200 PU: Protective Coating for Swimming Pools
Membrapol 200 PU is a pigmented, two-component polyurethane coating used as a protective finish.
The product is formulated to withstand demanding environmental conditions while helping maintain the appearance and protective properties of the treated surface.
According to the manufacturer's information, its main characteristics include:
-
UV resistance, particularly important for outdoor applications.
-
Resistance to continuous immersion in fresh and seawater, under the conditions specified by the manufacturer.
-
Resistance to certain chemical agents, within the limits stated in the technical documentation.
-
Good flexibility and mechanical resistance.
-
Colour and gloss retention, with high resistance to yellowing.
-
Ease of cleaning of the finished surface.
These properties make Membrapol 200 PU a potential option for finishing and protecting concrete swimming pools.
Nevertheless, a protective coating does not automatically replace every layer required for effective waterproofing.
The complete system must be selected according to the substrate, the intended use and the manufacturer's application specifications.
Swimming Pool Waterproofing in Fuerteventura: Local Factors to Consider
Fuerteventura's environmental conditions make regular swimming pool maintenance and suitable protective coatings particularly important.
Prolonged sunlight exposure, coastal environments and frequent pool usage can influence the ageing and performance of exterior finishes.
Sun Exposure and Ultraviolet Radiation
Outdoor swimming pools in Fuerteventura are exposed to significant solar radiation throughout much of the year.
For this reason, exposed finishes should offer suitable resistance to ultraviolet radiation and local environmental conditions.
A coating that loses adhesion, becomes discoloured or shows signs of surface deterioration may require maintenance or renovation.
Coastal Environments and Salt Exposure
Many residential properties and holiday villas in Fuerteventura are situated close to the sea.
In these locations, airborne salt can contribute to the deterioration of certain construction materials, particularly where coatings are damaged or metal components are insufficiently protected.
Regular inspection should therefore include pool surfaces, joints, fittings and areas where different construction materials meet.
Frequent Swimming Pool Usage
Private villas, holiday rental properties and tourist accommodation in Fuerteventura may use swimming pools throughout much of the year.
Frequent usage makes preventive maintenance particularly valuable.
Regular inspections can help identify minor defects before they develop into more serious problems.
Early detection of water leaks and surface deterioration can reduce the need for extensive repairs and help preserve the pool structure.
How to Prepare a Swimming Pool Before Waterproofing
The preparation process depends on whether the project involves a newly constructed swimming pool or the renovation of an existing structure.
Different conditions require different treatment methods.
1. Inspect the Pool Structure
The first step is to assess the condition of the pool floor, walls, corners and joints.
Special attention should be given to areas around pipe penetrations, skimmers, return jets, drains and other fittings.
Cracks, coating defects, poorly bonded areas and signs of infiltration should be identified.
2. Identify the Source of Water Loss
If the pool is losing water, determining the source is essential.
Leaks may originate from the pool shell, waterproofing layer, plumbing connections or hydraulic components.
Applying a waterproof coating without resolving the underlying problem may not eliminate the leak.
3. Clean and Prepare the Substrate
The surface must meet the cleanliness, strength, moisture and regularity requirements specified for the selected system.
Depending on its condition, preparation may involve removing incompatible coatings, repairing damaged concrete or levelling irregular surfaces.
4. Repair Cracks and Critical Areas
Cracks, joints and transitions between different construction elements require particular attention.
Not all cracks can be repaired using the same method.
Some may be superficial, while others may indicate structural movement or more significant defects.
5. Apply the Waterproofing System
Once the substrate has been properly prepared, the selected system can be applied according to the manufacturer's specifications.
For Membrapol products, correct mixing proportions, environmental conditions, material consumption, coating thickness and waiting times between layers must be respected.
6. Allow Proper Curing Before Refilling
Before filling the pool, the protective system must be allowed to cure for the required period.
Any specified inspections and testing should also be completed.
Premature filling or early exposure to pool treatment chemicals may compromise the performance of the coating.
When Should Swimming Pool Waterproofing Be Renewed?
Several warning signs may indicate that a swimming pool requires inspection or waterproofing refurbishment.
Common symptoms include:
-
A falling water level that cannot be explained by normal evaporation.
-
Cracks appearing in the pool floor or walls.
-
Blistering, peeling or detachment of existing coatings.
-
Visible moisture or infiltration in surrounding structures.
-
Deteriorated joints or areas around fittings.
-
Previous repairs that have failed to resolve water loss.
It is important to remember that a visually deteriorated coating does not necessarily indicate a structural water leak.
Similarly, a swimming pool that appears to be in good condition may still experience leaks through concealed plumbing or fittings.
An accurate diagnosis should therefore precede any waterproofing intervention.
