Flexible water proofing

Flat or pitched roofs covered with flexible waterproofing can be installed mechanically ­attached, bonded or ballasted and are very common on both commercial and public buildings.

The water proofing systems can be singly-ply ­synthetic based membrane waterproofing systems or bitumen based multi-layer or single layer membrane waterproofing systems. With RoofCalculator – Flexible Waterproofing it is possible to perform professional wind load calculations with any ­material group or installation method. In the data base you set up the materials and connect them to ­preferred fixing type or installation method. 

When performing the calculation ­RoofCalculator - Flexible Waterproofing will only display ­approved fastener combination which matches the selected structural deck and membrane system, this makes it very easy to use and safe. You avoid mistakes when it is not possible to select non-­approved product combinations. 

RoofCalculator-Flexible waterproofing supports fixing patterns in overlap seam as well as free field fixing patterns. The system also assists the user by displaying the efficiency factor of how much of the possible performance that is actually used based on the possible fixing pattern when installing a mechani­cally attached system on profiled steel decks which only allows fixing in the crown of the deck.

If a wide Single ply waterproofing system is selected it might not be possible to use the full width in the roof zones with the highest wind loads. RoofCalculator – Flexible Waterproofing automatically includes center lines fixings/intermediate fixing rows which can be covered with cover strips. 

Another option is to use the optimizer tool when selecting the waterproofing membrane system. RoofCalculator – Flexible Waterproofing will then choose the best possible membrane width for each roof zone to avoid center line fixings/intermediate fixing rows.

With the user-friendly step by step interface the software guides the user through the needed steps when performing the calculations. It is also possible to include linier fixation at the parapet of the roof, either as spot fixings or as linier steel bar. 

When the wind load calculation is executed the wind load calculation report can be printed as a PDF. The roof drawing can be printed as an (A3) PDF or a DXF file to be used in any other CAD system.
