TOPWET

company is the largest producer of flat roof drainage in Czech Republic.
And that's just one of the reasons to work with us...

Continually innovating

We at TOPWET have been cooperating for a long time with experts from the development departments of the Brno University of Technology (especially with FAST VUT Brno, especially with the Institute of Civil Engineering, the Institute of Water Engineering and the Institute of Municipal Water Management), we are constantly increasing the professional competence of our employees and constantly improving the quality of our products and their certifications.

Focus on
quality

Our main goal is to provide high quality products and services, resulting in satisfied and successful business partners and customers. We achieve product quality from material selection, through design decisions, to testing of individual products. You can rely on the quality of our products.

Efficiency

We design our products to be as easy to install as possible. We know that improperly installed drains can cause water to penetrate the roofing material. This is completely prevented by our integrated sleeve, which is pressed firmly between the drain body and the top flange and then ultrasonically welded - this joint is completely watertight. During installation, the drain is simply pulled out of the box and placed directly into the mounting hole, then the drain is anchored and the sleeve is welded.
