Balcony/terrace floor drain horizontal/vertical with adjustable joint, DN50/75 with bituminous collar, cast iron cap class L15 (1.5t) and odor trap HL81GH

Balcony and terrace gully with adjustment and bituminous collar

This balcony and terrace gully, designed for gravity drainage, is a reliable solution for draining water from balcony and terrace surfaces. A key feature is the ability to create a watertight connection with the bituminous waterproofing layer thanks to the collar. This is essential for ensuring long-term protection against leaks and moisture.

Construction and application

The DN50/75 drain pipe has adjustable outflow angle within a range of 90 degrees, which facilitates adaptation to specific installation conditions and allows for optimal water direction. The flange with a cast iron grate of class L15 (1.5t) is height adjustable in the range of 30-75mm, allowing it to be adapted to different thicknesses of the balcony or terrace structure. The built-in anti-odor flap prevents unpleasant odors from the sewer system from entering the rooms.

The gully flow rate is 0.8 l/s, making it suitable for surfaces up to 26m2 with typical rainfall intensity (300 l/(sxha)). The possibility of expanding with additional elements – simple extensions, collars or a drainage ring – allows for flexible adaptation of the drainage to the specifics of a given project. For those planning to heat the terrace, it is worth considering the use of the HL82 heating set.

This gully is distinguished by its tightness thanks to the bituminous collar guaranteeing the integrity of the waterproofing. The adjustable outflow angle facilitates installation and optimizes water drainage, and the durable cast iron flange of class L15 provides resistance to loads up to 1.5 tons. The anti-odor flap increases user comfort by eliminating unpleasant odors. The flexibility of the system allows adaptation to different roof layers arrangements through expansion with additional elements, and the flow rate of 0.8 l/s ensures effective drainage of water from surfaces up to 26m2.
