The spiked membrane is a modern waterproofing material of a wide range of applications. The spiked membrane performs the functions of drainage, waterproofing protection, replacement of the lining, saves time on construction and increases the service life of structures. Due to its spiked shape, the drainage membrane creates a protective layer that promotes the removal of water and moisture, prevents damage to the applied waterproofing, and also evenly distributes the load on the surface of the canvas.

What is the scope of the spiked membrane?

replacement of concrete preparation
foundation hydraulic protection and drainage system
the system of hydraulic protection and drainage of the "green roof"
construction of underground structures using the "wall in the ground" method
waterproofing protection of foundations
tunnel hydraulic protection system
rehabilitation of wet walls
foundations up to 2 meters deep
basement and retaining walls
as a podbetonki
blind spot

The thickness of the material and the properties of the raw materials from which it is made allow the product to be used as a reliable waterproofing of a wide variety of structures

What kind of membrane should I choose?

In order to protect the waterproofing layer from mechanical damage during backfilling of the soil, we recommend using a conventional membrane without geotextile. The spiked membrane, due to its structure, is a material that is able to withstand significant loads from the ground
When using a spiked membrane as a drainage layer, use a membrane with SNTDRAIN DL8 GEO geotextile

Which spike-shaped membrane should I choose to protect the waterproofing of the foundation?

Foundation up to two meters deep - spiked membrane SNTDRAIN EKL400
Foundation with a depth of more than 2 meters - spiked membrane SNTDRAIN EKL500

Is it possible to use a spiked membrane in road construction?

When building a road, the recommended use is the spiked membrane SNTDRAIN EKL600

Is it possible to use a spiked membrane for a winter garden?

In order to accumulate moisture for winter gardens or roof gardens, a drainage membrane is also used. In such constructions, it is laid with spikes down. The spikes serve as mini-reservoirs for the accumulation and retention of moisture, which will eventually evaporate and moisten the soil in a capillary way.

Which side should the spiked membrane be laid?

To replace the concrete preparation, the spiked membrane is laid with spikes down.
To protect the waterproofing from damage, the spiked membrane is laid with spikes to the waterproofing.
To remove moisture from the wall, as wall drainage, in the blind area system and the roof being operated – with spikes and geotextile outside.

To fix the edges of the drainage membrane to the wall, they must protrude beyond the upper edge of the main waterproofing, or 10 cm above the level of the earth filling.

How to use a spiked membrane in vertical application?

Remove dust and debris from the surface
Place the sheet on the surface with spikes to the wall
Fix the sheets on the wall along the upper edge of the base with a fastener
The overlap of the sheets should be at least 20 centimeters
The connections are fixed with self-adhesive tape or hot air soldering
Application temperature: - 5°C to 30 °C

How to use a spiked membrane with horizontal application?

Lay the sheet on the platform with spikes to the ground.
The sheets overlap with each other by 30 centimeters.
The connections are fixed with self-adhesive tape or hot air soldering
Application temperature: - 5°C to 30 °C

The spiked membrane has high compressive and tear strength and is resistant to moisture, fungi, soil bacteria and chemicals.
