Dimpled membranes

We are happy to announce that high-density polyethylene (HDPE) dimpled membranes have been added to the Hydroseal OÜ product range. They are high-quality, durable membranes that provide complete protection against moisture for foundations and other underground concrete structures.


Dimpled membrane is intended for waterproofing the foundation of the building, as well as all underground concrete structures. In addition to protecting the foundation or basement wall from soil water/excess moisture coming from the outside, it also ensures the drainage of condensation water from moisture coming from inside the building.

Places of use:

• building foundations
• concrete floors built on soil
• basement walls
• retaining walls
• various underground buildings (e.g. parking garages, tunnels)

A foundation cover is used primarily for structures where the anticipated amount of condensate to be drained is not particularly high (i.e. the normal situation) and where the infill soil around the foundation, basement wall or retaining wall allows normal surface water filtration.

Dimpled membranes are available in three different widths: 1; 1.5; and 2 meters. Each roll is 20m long.

Moisture barrier tape is a geomembrane made of high-density polyethylene (HDPE) and designed for horizontal installation on a wall. This protects the structural elements of the wall from capillary moisture penetration and upward moisture uplift. The moisture barrier tape remains flexible even at -30°C, unlike membranes made of PVC material. It also replaces bituminous materials such as tar paper and pitch. The surface of the membrane has double-sided grooves that prevent the tape from moving.

It is available in a 0,3m wide roll. The roll is 50m long.
