To ensure the drainage system is compatible with the Sika-Trocal roofing system, and provides effective drainage, high quality injection moulded gravity fed rainwater outlets and scuppers can be used. Where alternative rainwater outlets or scuppers are used compatibility with the Sika-Trocal membrane must be checked, the outlets must also provide an effective sealing method.


Where Sika-Trocal rainwater outlets are used the Sika-Trocal membrane is simply welded to the injection moulded flange incorporated into the body.


Roofs that are drained internally, that is when there is a parapet all the way around the roof perimeter, should incorporate some sort of over flow provision to at least give warning and relief in the event of the normal outlets becoming blocked. This can be achieved by using the purpose made Sika-Trocal Warning Pipe/ Scupper with a 75mm pipe spigot.

SPL Scupper PVC

The Sika-Trocal Rainwater Outlet is made of rigid PVC. It is highly esistance to weathering, including UV irradiation, and is stress-cracking resistant. The Sika-Trocal membrane can be welded directly to the base plate for ease of application, and it is recycable.
