| Rainwater Systems
Purpose and Key Role of a Rainwater System
Rainwater systems are a set of external components essential for the organized collection and drainage of atmospheric precipitation from the roof. Their main task is to protect the facade, plinth, and foundation from the destructive effects of moisture. Effective drainage prevents erosion, flooding, and damage to waterproofing, ensuring the longevity of the entire building.
In a climate where frequent precipitation can alternate with intense downpours, the key factor is not just the presence of a gutter, but its correct hydraulic calculation. A simple calculation based on roof area is not enough. The system must be designed according to European standards (EN 12056-3) to handle peak rainwater loads.
A properly selected and certified system:
- Guarantees protection of the foundation and facade from excessive moisture and decay.
- Prevents uncontrolled water runoff, soil erosion, and basement flooding.
- Ensures drainage capacity calculated for peak rainfall loads (according to EN standards).
- Gives the building a finished, architectural appearance.
- Significantly extends the service life of the roofing structure and the entire building.
Types of Rainwater Systems
We offer a full range of metal solutions for water drainage, from standard steel systems to exclusive solutions in non-ferrous metals, manufactured to your specifications.
-
Round System
A classic, time-tested solution. The half-round gutter and cylindrical downpipes ensure effective water drainage. We offer round systems made of galvanized (ZN) and polymer-coated (PE) steel.
-
Profiled (Square) System
A modern, minimalist design. Systems with a rectangular or square cross-section for gutters and downpipes. Ideal for modern architecture. We offer these in ZN, PE, and Pural coated steel.
-
Custom Solutions
Manufacturing of any gutter elements according to your sketches. We produce custom funnels, elbows, square gutters, as well as complete systems from premium materials: copper, titanium zinc, and stainless steel.
Rainwater System Materials
The durability of a rainwater system is determined by the quality of the material. We manufacture metal systems that comply with European standards for any task and budget.

Modern architecture, complex roof shapes. |
| Stainless Steel (AISI) |
Maximum strength and resistance to corrosive environments. |
Industrial areas, coastal regions, special architectural projects. |
A wide range of shades is available for systems with polymer coatings (PE, Pural) from the full color catalog.
Advantages of Working with a Manufacturer
We do not just sell, we manufacture metal rainwater systems ourselves in Riga. This gives our clients several key advantages:
- Free Calculation: We provide free consultations and help perform a correct hydraulic calculation of the system according to EN standards.
- Full Kit: You receive not only pipes and gutters, but a complete set of necessary installation materials (rivets, screws, sealant), as well as all roofing accessories in the same color.
- Flexibility: The ability to combine elements, for example, using profiled (square) gutters with round downpipes.
- Installation Services: We offer high-quality and fast installation of all our products.
- Lead Times: Our own warehouse and production allow us to complete standard orders within 1-3 working days.
Installation: From Components to Professional Setup
Correct Slope is Key: The crucial aspect of rainwater system installation is ensuring a correct and consistent slope (usually 3-5 mm per meter). This guarantees that water flows to the funnel by gravity and does not stagnate.
Everything for Installation: We offer not only gutters and pipes, but also a complete installation kit: brackets for any roof type, corners, funnels, connectors, as well as all necessary fasteners (rivets, screws) and sealant.
Professional Installation: If you want to guarantee a perfect result, SIA "Akvilon" offers professional installation services. Our in-house specialists ensure the correct installation of all components, adherence to slopes, and sealing of joints to guarantee the efficiency and durability of the entire system.
Production of Custom Solutions
SIA Akvilon offers the production of custom sheet metal products based on your sketches. If standard components are not suitable for your architectural task, our production facility is ready to handle a custom order.
We produce on-demand:
- Elements of non-standard shapes and configurations (square gutters, special funnels, elbows).
- Any components based on client sketches and drawings.
- Complete rainwater systems from premium materials: stainless steel, titanium zinc, copper.
Our production has a successful track record in designing, manufacturing, and installing custom solutions. SIA Akvilon guarantees the quality, professionalism, and durability of all its products. (Lead times for custom parts may be extended).
