Stacking the thorny membrane
A spiked or drainage membrane is a modern roll material that provides effective water drainage from walls, foundations, and roofs. It also protects the waterproofing layer from mechanical damage and extends the service life of building structures.
This material is indispensable for creating high-quality waterproofing on various objects - from private houses to industrial buildings. Due to its special structure, the spike-shaped membrane not only drains water, but also provides protection against capillary moisture and radon.
Scope of application of the spiked membrane:
Protection of waterproofing from mechanical damage - the membrane reduces the risk of damage to the insulation layer during soil settlement.
Plastic drainage is an ideal solution for vertical and horizontal drainage systems, ensuring reliable water drainage.
Replacement of concrete preparation - used as an economical alternative in construction.
Underground structures are indispensable for the "wall in the ground" method, protecting against water penetration and maintaining the stability of the structure.
Industrial and warehouse floors - acts as a separating and drainage layer, preventing moisture accumulation under the structure.
Operated and "green" roofs - creates a reliable drainage layer for water drainage, promoting plant growth and preserving the roofing layer.
Protection against capillary moisture - provides effective cut-off insulation for building walls.
Radon protection - prevents the penetration of dangerous gases from the soil into the building.
The main advantages of the spiked membrane:
High compressive strength - withstands significant loads without losing its shape.
Resistance to impacts and surface loads - ensures durability even under high usage conditions.
Resistance to UV radiation - does not lose its properties under the influence of sunlight.
Chemical and bacteriological resistance - not affected by aggressive substances and microorganisms.
Technology of laying a spiked membrane
The installation of a spiked membrane depends on the specific application (foundation, roof, floor). The basic principle of installation is to create an effective drainage layer that drains water away from building structures.
1. Choosing the laying side
The membrane should be laid with the spikes facing the moisture source (e.g. the ground when insulating a foundation). This allows water to drain freely down the spikes, while the air gap provides ventilation and reduces the risk of condensation.
2. Installation of the membrane on vertical surfaces (foundation, basement walls)
We unroll the roll from the bottom of the structure upwards.
The spikes should be directed towards the wall to create a ventilation gap.
The membrane is attached with mechanical dowels at 30–50 cm intervals.
The joints are overlapped by at least 10–15 cm and secured with sealing tape.
3. Installation on horizontal surfaces (roof, floor, drainage system)
Roll out the membrane on the surface with the spikes down for effective moisture removal.
The edges of the membrane must extend onto vertical surfaces by at least 10 cm.
The joints are also laid with an overlap and sealed.
For additional stability, the membrane can be covered with a layer of crushed stone or sand.
Additional installation recommendations
Avoid laying the membrane during rainfall or on a wet surface.
Carry out installation at temperatures between +5°C and +30°C to achieve maximum material efficiency.
Use special sealants to seal joints and attachment points.
After installation, check for damage.
