TOPWET

Leader in the production of drainage systems for flat roofs

innovation

At TOPWET, we have been cooperating with experts from BUT development departments (especially FAST BUT, specifically, with the Institute of Civil Engineering, the Institute of Water Works and the Institute of Water Management of Municipalities), constantly increasing the professional competence of our employees and constantly improving the quality of products and their certifications.

quality

Our main goal is high quality products and services, and thus a satisfied and successful business partner and customer. We achieve product quality from material choices, design decisions to individual product testing. You can rely on the quality of our products.

Effectiveness

We design our products in such a way that their installation is as simple as possible and that there is as little room for error as possible. We know that improperly assembled drains can lead to water ingress into the roof material. This is completely prevented by the integrated cuff, which is tightly pressed between the inlet body and the upper flange, followed by ultrasonic welding — this joint is completely waterproof. During assembly, the inlet is simply pulled out of the box and directly inserted into the mounting hole, the cuff is buckled and closed.

Company history

TOPWET is a Czech manufacturer of systems for drainage of flat roofs. We combine our own development, production and technical support to make design, ordering and assembly simple, fast and worry-free.
A good roof is based on the details. In our country, the details are the inlet, overflow and connection points — places where the roof actually works. In the heart of Europe, we design and manufacture solutions where thoughtful hydraulics, precision and durable materials meet. We keep everything under one roof.
The system has to work and endure. Therefore, we use materials resistant to UV, frost and chemical waterproofing, integrate collars for conventional systems (PVC, TPO, asphalt strips) and offer dimensions and configurations for new buildings and renovations. Optional heating and accessories ensure reliable operation in harsh conditions. Each piece goes through quality control.
We are a partner of the project — technical documentation, detail drawings, samples, consultations, stock availability and fast logistics for smooth implementation.
TOPWET doesn't just make gullies and overflows. We make them a detail that keeps the roof in operation.

Petr Polášek
KST MEMBRANE s.r.o.

We have been cooperating with TOPWET since the beginning of our company, since 2010. At that time, TOPWET was also at the beginning of its journey. Within a couple of years, they managed to replace their poor quality products with their excellent products, which have a good reputation not only in our country, but also throughout Europe. Their approach, service and consultancy are at a very high level, which is unchanging during the entire period of our cooperation. New ideas, technical solutions, and especially listening from the flat roofs industry place TOPWET at the first positions in this field. Without their products, it is difficult to imagine a flat roof.
