Rainwater drainage from balconies and terraces

Today we will talk about an indispensable element on any terrace and balcony – a double-hull ladder.
A double-hull ladder is used to drain rain and industrial water, protects the surface from moisture, which leads to the destruction of the coating.

Double-hull ladders are made of durable materials, the grilles are made of stainless steel, the remaining elements are made of plastic.Advantages of ladders:

Multifunctionality – used on almost any outdoor terraces.

Prevent the penetration of moisture into buildings.
High throughput.
Strength and compactness
Resistance to chemical, mechanical and thermal influences

At the design stage, it is necessary to remember the following requirements in order to avoid errors in use:Each ladder has its own estimated catchment value.

Important parameters for the selection of the ladder are the estimated amount of rainwater (Q, l/s) and its throughput (K, l/s)
It is necessary to pay attention to the place where the waterproofing is joined to the flange to prevent water leakage
To drain rainwater from balconies and terraces, there should be a separate storm sewer with vertical drainage with horizontal drainage

How the installation process works:It is necessary to determine the direction of the outlet

Installation of the ladder is installed at the lowest point of the surface
The housing is securely installed in a place where it comes into contact with other structural elements
Next, it is necessary to securely fasten the ladder body in places of contact with the structure
Special membrane and flange made of stainless steel, mounted with waterproofing and vapor barrier of the terrace floor itself
For easy maintenance of the ladder, it is necessary to provide free access
