SAFE ROLL – dimpled membrane for below-ground walls
Safe Roll is a special dimpled membrane designed to protect underground walls. The “dimples”, truncated-cone protrusions that characterize the product, create air gaps within the insulating layer, allowing water to drain outward.
The dimpled membrane provides permanent mechanical protection and also shields the bituminous insulation layer from damage during backfilling of foundations and in the event of building settlement.
It is installed like a waterproofing product but also ensures proper ventilation of the external foundation wall.
This is a non-biodegradable material, resistant to chemical compounds, fungi, bacteria, and root growth. It maintains its properties over time and does not contaminate water it comes into contact with.
SAFE ROLL
ADVANTAGES
PROTECTS AGAINST HUMIDITY
SAFE-ROLL is the ideal solution wherever humidity represents a risk for the construction project.
ENSURES AIR CIRCULATION
When laid horizontally on a lean foundation slab, it protects floors from rising damp. Thanks to its semi-conical dimples, it distributes loads effectively and creates a cavity that promotes air circulation beneath the floor, ensuring its waterproofing.
UNIVERSAL APPLICATION
From safeguarding foundations, to insulating ceilings, terraces, and balconies, up to drainage and ventilation layers.
LONG-LASTING DURABILITY
Safe Roll remains stable over time, does not contaminate water, and does not release pollutants.
RESISTANT TO BACKFILL DAMAGE
It also protects the bituminous waterproofing layer from damage during foundation backfilling and in the event of building settlement.
PERMANENT MECHANICAL PROTECTION
The dimpled membrane provides permanent mechanical protection.
FEATURES
Supply and installation of protective dimpled HDPE membrane, type Safe Roll, thickness 0.5 mm, dimple height 8 mm, weight 500 g/m2, roll length 20 m, height ... Longitudinal overlaps must be at least 15 cm, and transversal overlaps at least 10 cm. Along the upper edge, the membrane must be nailed using steel nails and fixing washers at intervals of approx. 100 cm (variable depending on the height used).
A Profile accessory can be applied along the upper edge of Safe Roll to prevent soil from entering between the protection layer and the waterproofing during backfilling.

Frequently asked questions about SAFE ROLL
SAFE ROLL is an HDPE dimpled membrane designed to protect waterproofing during backfilling by distributing soil pressure and creating a micro air cavity.
The membrane has a compressive strength of approximately 230 kN/m² and can be used in below-ground structures up to 5 metres deep, depending on the project design conditions.
SAFE ROLL is the ideal choice when waterproofing protection is required without increasing the overall thickness.
Where greater physical separation from the soil and enhanced drainage performance are needed, a system such as SKUDO may be a more suitable solution.
