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.

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.
