What is the difference between PVC and polypropylene channels?

PVC channels stand out for their excellent balance of price and durability, as well as their resistance to corrosion and UV rays. They are widely used in residential and commercial environments. On the other hand, polypropylene offers greater chemical and mechanical resistance, making it ideal for areas exposed to heavier traffic, cleaning products or harsh environmental conditions.

Plastic channels

Q: Where is their installation recommended?

Plastic channels are highly versatile. They can be installed around homes, on terraces, patios, gardens, in garages or car parks. They are also used in industrial and public environments where large volumes of water need to be drained without compromising the area's aesthetics or safety.

Q: What formats and sizes are available?

We have channels available in different lengths, widths and depths to suit every hydraulic requirement. Depending on the model, you can find round, square or trapezoidal cross-sections, as well as different types of grating (metal, plastic or cast iron) to match the required load class.

Q: Can I install these channels myself?

Yes, the modular design of plastic channels makes installation simple and quick. You just need to ensure the correct gradient, that the sections are joined properly and that the joints are sealed. However, for large-scale projects or in areas with heavy traffic, it is always advisable to use professional installers to guarantee the system's maximum safety and durability.

Q: How long do plastic channels last and what maintenance do they require?

Plastic channels require minimal maintenance. They just need to be cleaned periodically to prevent leaves, sand or other debris from obstructing the water flow. With correct use, they can maintain their properties for decades, easily withstanding both sun exposure and frost.

We answer your questions about our plastic drainage channels

What is the difference between PVC and polypropylene drainage channels?

PVC channels stand out for their excellent balance between price and durability, as well as their resistance to corrosion and UV rays. They are widely used in residential and commercial environments. Polypropylene, on the other hand, offers greater chemical and mechanical resistance, making it ideal for areas exposed to heavier traffic, cleaning agents or demanding environmental conditions.

In which locations is their installation recommended?

Plastic drainage channels are very versatile. They can be installed on residential roofs, terraces, patios, gardens, garages or car parks. They are also used in industrial and public environments where large volumes of water need to be drained without compromising the aesthetics or safety of the area.

What formats and sizes are available?

We offer drainage channels in various lengths, widths and depths, to suit every hydraulic requirement. Depending on the model, they are available with round, square or trapezoidal profiles, as well as various types of grating (metal, plastic or cast iron) to suit the required load class.

Can I install these channels myself?

Yes, the modular design of the plastic drainage channels allows for a quick and simple installation. You simply need to ensure the correct gradient, that the sections are joined correctly and that the joints are sealed. However, for large-scale projects or in areas of heavy traffic, it is always advisable to use professional installers to guarantee the maximum safety and durability of the system.

How long do plastic channels last and what maintenance do they require?

Plastic drainage channels require minimal maintenance. Periodic cleaning is sufficient to prevent leaves, sand or other debris from obstructing the flow of water. With proper use, they can maintain their properties for decades, withstanding both sun exposure and frost.

How plastic gutters work

The working principle is simple but effective: the channels collect water that falls on surfaces such as roofs, terraces or pavements, and direct it to the drainage points. Thanks to their modular design, water flows freely until it discharges into outlets, gullies or downpipes that safely redirect it to the drainage system or a collection point.

Their effectiveness depends on correct installation: maintaining the correct gradient, fixing the supports at the recommended spacing, and choosing the most suitable material according to the intensity of use or the expected volume of water. In this way, plastic channels ensure smooth drainage and prevent ponding, leaks or structural damage.

Advantages of plastic channels

These types of drainage channels offer numerous benefits:

Lightweight and easy to install: being lighter than their metal counterparts, they require less effort for handling and installation.
Corrosion and chemical resistance: ideal for areas exposed to constant moisture or harsher environments.
UV and frost resistance: they maintain their properties without warping or cracking.
Noise reduction: they absorb the sound of water more effectively than metal systems.
Easy maintenance: quick to clean and requires no additional protective treatments.
Variety of sizes and finishes: a range of cross-sections, colours, and gratings to suit any project.
Cost-effective: they are more economical than other solutions, both in initial cost and in installation and upkeep.
