What is a dimpled sheet profile?
A dimpled sheet profile is a finishing edge for a dimpled membrane. In the BMSC24 online shop you’ll find various versions made from PVC and stainless steel, designed to provide reliable protection for the base of the wall.
What is a dimpled sheet profile used for?
A dimpled sheet profile is often used as part of structural waterproofing systems to help prevent water from penetrating a building. For example, it can be used in foundation waterproofing or as a protective layer for basement walls.
It can also be used as a drainage layer in gardens, parks or on roofs to ensure effective water run-off. In addition, the profile can serve as a separation layer between different building materials or as a protective layer beneath floor coverings.
What material is a dimpled sheet profile made from?
A dimpled sheet profile is usually made from polyethylene (PE), a thermoplastic that is well suited to construction thanks to its chemical resistance, low density and good mechanical properties. The material is typically black and is produced by extrusion, creating dimples on one side and a smooth surface on the other. The dimples form drainage channels that help protect foundations and walls against moisture and water.
Which quality criteria matter for a dimpled sheet profile?
Material quality: Ideally, the dimpled sheet profile is made from high-grade polyethylene (PE) with strong resistance to chemical and mechanical impact.
Thickness: The thickness should be sufficient to ensure stability and effective protection. Minimum thickness varies depending on the application and is defined in the relevant standards and regulations.
Dimple height and spacing: These must be designed to ensure effective drainage and reliable protection against moisture.
Puncture and tear resistance: The profile should offer adequate puncture and tear strength to prevent damage during installation and use.
Water permeability: The profile should allow sufficient water flow so that water can be drained away effectively.
What’s the difference between a dimpled sheet profile and a dimpled membrane?
A dimpled membrane is a type of drainage and protective sheet that is often installed beneath foundations, patios or roads. It consists of a plastic sheet with raised dimples that create a drainage function.
A dimpled sheet profile, on the other hand, is a plastic or metal profile that is typically used as a fixing and finishing component for dimpled membranes. It is fitted along the edges of the membrane to improve stability and to prevent the membrane from slipping or shifting.
In short: the dimpled membrane is the actual drainage/protection sheet, while the dimpled sheet profile is the accessory used to secure and stabilise it.
How does a dimpled sheet profile protect the structure?
A dimpled sheet profile essentially creates a drainage and ventilation gap on foundations and walls to protect the building fabric from moisture. It is installed directly on the surface, with the dimples facing outwards.
The dimples increase the distance between the profile and the substrate, allowing air to circulate. This helps prevent moisture build-up on the surface, reducing the risk of mould and other moisture-related damage.
In addition, the profile enables controlled drainage of water away from the surface. Water is guided through the dimple structure towards the lower area, where it can then be directed away via drainage paths.
Overall, a dimpled sheet profile helps protect the structure from moisture and related damage by supporting controlled drainage and improved ventilation.
How is a dimpled sheet profile installed?
The dimpled sheet profile is generally fitted to a prepared substrate and acts as a protective layer against penetrating water and moisture. The dimple structure creates a cavity between the profile and the wall, which functions as a drainage layer and channels moisture away.
