Polyurethane Singular Points
Frequently, it is necessary to do conditioning work before applying DESMOPOL since this ensures that the principal function of the waterproofing is completely effective and lasting. Below we cover the most common actions needed. If your case is not reflected, do not hesitate to get in touch with the Technical Department of Tecnopol, a technician will assist you and will analyze your case thoroughly.
In rehab jobs, when the drain is ready, place a casing or geotextile mesh that exceeds the diameter of the downspout by aprox.10 cm, which will be impregnated by the membrane, so it will adhere to the support.
Fill the whole length of the joint with our polyurethane putty DESMOSEAL MASILLA-PU and immediately, apply a band of waterproofing armed with geotextile. This should be covered between 10 and 15 cm to each side of the joint.
Fissures and cracks
Passive fissures and active fissures of more than 3 mm. of breadth. After opening with disc, seal it with DESMOSEAL MASILLA-PU. When the putty dries, apply DESMOPOL, make sure to do a compatibility test.
Sharp edges as well as angular points and edges must be rounded with DESMOSEAL MASILLA-PU adding a geotextile mesh when necessary.
Parapets also need conditioning before applying DESMOPOL.
Wiring / Wall openings
Cables and wall openings in roofs are considered singular elements, and must be treated before waterproofing work is started.
