more about topwet

More than outlets and membranes – complete

care for your

roof.

Make your work easier – on site and in the office!

Every flat roof is a system. And a system is only as strong as its weakest element. Others focus on a single segment – where they stop, we continue. We have simplified the riskiest detail, the outlet, for all types of waterproofing materials. For vents and penetrations we ensure not only watertightness but also a clean appearance. Why deal with every detail and accessory of your project with a different supplier? Our technical department is ready to help design and recommend the product that will help you deliver your project at the level of the biggest professionals.

Frequently asked questions

Why source all roof details from one supplier?

Because a flat roof works as a whole. When individual elements come from different manufacturers, problems with material compatibility, installation and responsibility often arise. The complete solution from TOPWET ensures that all details fit together technically and in terms of materials.

How is TOPWET different from a standard drainage manufacturer?

Most manufacturers offer only outlets and usually one type of vent. TOPWET supplies a complete system of details: drainage, penetrations, ventilation, fittings, inspection chambers, solutions for green and walkable roofs and structural details at railings, parapets and slopes.

Are all elements compatible with the waterproofing material?

Yes. We use original sleeves made of waterproofing materials from renowned manufacturers. These are not universal substitutes – the details are fully compatible with the membrane used on the roof.

What if I have an atypical detail or a non-standard solution?

Atypical solutions are a normal part of our work. We design the structural solution, prepare the drawings and manufacture the detail to measure.

Do you provide technical support?

Yes, technical support is free of charge. We help designers, contractors and investors with detail design, roof build-up and problematic spots.

How fast can you deliver all the necessary elements?

We keep most of the range in stock. Standard products are dispatched the same day, atypical ones usually within 2–5 working days.

Isn't a complete solution more expensive than combining several suppliers?

It may look that way at first, but in practice it is often more economical. You save installation time, reduce the risk of mistakes, eliminate complaints and simplify responsibility. The total costs are lower.

How do I find out which products are in stock?

In our B2B portal you can see current stock availability in real time and order straight away.

Is your solution suitable for large projects too?

Yes. Our system solutions are designed for residential, commercial and industrial buildings – from smaller buildings to large-scale projects.

Who is responsible for the functionality of the details?

With a complete solution, responsibility is clear. All elements come from one system with uniform technical rules and guarantees. This is a fundamental advantage over combining several suppliers.
