Our flat roof waterproofing system

Roof edge trim profiles

What good is excellent work without a sophisticated finish? With high-quality alwitra roof edge trim profiles made of noncorrosive aluminium, this issue does not even arise. Time-saving installation, smart and clean sealing, tension-free and flexible flashing with guaranteed durability – what a great finish!

Wall capping profiles

You can, of course, spend hours taking measurements, doing manual bending, checking and, maybe, reworking - but you don't have to. Time is a scarce, precious resource, so why not let others do the bending - us, for example? The roofers on site can thus focus on installing perfectly fitting, long-lasting, industrially manufactured wall capping profiles. Sounds easy, doesn't it? Well, it is.

Wall flashing profiles

Waterproofing membranes on rising building elements need their extra share of attention: prevention of slippage, security against rain and protection from mechanical damage on used and non-used roof areas. Wall flashing profiles from alwitra: light and elegant, durable and robust - the end-all be-all for flashing roofing membranes against rising building elements.

Paving slab support

For those who want to enjoy sunny days on their terrace as quickly as possible: alwitra paving slab supports can be aligned in no time, they offer ample space for concealing pipes and cables, ensure reliable drainage and are extremely weather-resistant – and, finally, they give you significant cost advantages. The paving slab supports are placed under each cross joint of four slabs. Spacers ensure a regular joint pattern.

Daylight system

About 80 % of all our sensory impressions are purely visual – so let’s make something of it. Sufficient daylight saves energy, lifts your spirits, increases the aesthetic effect of any room, provides non-dazzling lighting, and is demonstrably healthy. Of course, without having to compromise on tightness or thermal insulation.

Flat roof vent

Every downpipe in a building serving as a vent line must protrude above the flat roof. Fortunately, this is not a problem with alwitra flat roof vents: The alwitra vent stack forms the upper end of drainage downpipes protruding above low slope waterproofed roofs of any constructional type. At cold roofs, the alwitra cold roof vent ensures appropriate air circulation in the air space. You want to refurbish an existing roof? In this case, the alwitra refurbishment vent ensures easy, quick, and reliable flashing of existing vent lines up to DN 150 against the new waterproofing without prior removal.

Waterproofing membranes

Our alwitra synthetic waterproofing membranes are designed to provide consistently superior performance on flat roofs. Easy handling, quick installation, and a homogeneous bond, ensuring long term watertightness. For new build and refurbishment projects, loose-laid, mechanically fastened or adhesive-bonded. Time-saving and sustainable. Builder-owners really love neat, beautiful, reliable, and eco-friendly flat roofs. Because sustainability needs pioneers.

Flat roof drainage

Torrential rain, storms and flash floods are unlikely to become less frequent in future – so be clever and think ahead: with alwitra flat roof drainage systems, you can take the initiative and prevent problems from arising in the first place. Rainwater outlets, emergency outlets and water spouts from alwitra keep both feet and heads dry under any flat roof – for years to come, even when it’s raining cats and dogs.

The EVATEC® Solar mounting rail is placed on the finished roof sealing and fastened directly into the base layer with (long) roofing screws. Roof openings or penetrations are not required.
