Dörken Italia Delta®-terraxx Drainage System
DELTA®-TERRAXX DRAINAGE SYSTEM
DELTA®-TERRAXX DRAINAGE SYSTEM
Universal protection and drainage system for green areas that can be walked on or driven on and for vertical applications with installation depths of up to 10 m.
Like all DELTA®-TERRAXX types, the material combination of pressure-resistant dimpled sheet and laminated, filter-stable geotextile serves as a drainage layer and effectively protects pressure-resistant substrates from mechanical influences. The strips have an integrated self-adhesive edge and a tested long-term durability of 100 years.

APPLICATION
The universal protection and drainage sheet can be used:
- For flat roofs with heavy surface protection made of gravel
- Under extensively and intensively green areas
- Under walkable surfaces with and without base or leveling course,
- Under surfaces that can be driven on by cars
- In vertical applications with installation depths of up to 10 m and
- As reliable methane gas and radon drainage.
The DELTA®-TERRAXX strips are available in a width of 75 cm for paths, bases, retaining walls and connections.

ADVANTAGES
QUICK ON BIG SURFACES AND STILL SIMPLE IN THE DETAIL
Thanks to the roll-format of 12.5x2.40 m, 30 m² can be laid very quickly and in one step. Delta-terraxx can easily be cut to size with a simple cutter knife for detailed works. The handling is also easier than handling a rubber mat/roll.
INTEGRATED SELF-ADHESIVE EDGE
The smooth overlap edge with integrated adhesive zone enables the strips to be easily connected to one another. This prevents backfill material from trickling in, so that the seal is additionally protected. The positional stability of the individual webs is also improved.
IDEAL DIMPLED SHEET
Due to its optimal ratio of knob structure and weight per unit area, the dimpled sheet with a height of 10 mm, offers the ideal combination of compressive strength, drainage performance and handling. The DELTA®-TERRAXX ensures a drainage capacity of 2.51 l/s·m even at a installation depth of 10 m.
SIGNIFICANTLY HIGHER WATER DRAINAGE CAPACITY THAN A MINERAL DRAINAGE LAYER
The special knob structure of DELTA®-TERRA ensures an ideal water drainage and permanently protects pavements and slab coverings from frost damage. The dimpled membrane forms a 10 mm high drainage layer, which is way more efficient than a 20 to 30 cm thick mineral seepage layer.
UNIVERSAL PROTECTION AND DRAINAGE MEMBRANE FOR VERTICAL AND HORIZONTAL APPLICATIONS
As a water-bearing layer, DELTA®-TERRAXX protects against backwaters, strata and seepage water. The optimal solution for maximum security. Your advantage: only one product for many different fields of applications!
CONFORMITY TO STANDARDS
Delta®-terraxx is certified/ce-marked according to en 13252 and meets the requirements of din 4095, din 18531 and din 18533.
100 YEARS OF TESTED LONG-TERM RESISTANCE
As a product with tested long-term resistance of up to 100 years, DELTA®-TERRAXX is free of recycling material in accordance with DIN EN 13252 and has passed extensive tests for aging resistance by independent and accredited test institutes. In this way, with DELTA®-TERRAXX you can benefit from the permanent and sustainable protection of the whole building shell.
EVEN LOAD DISTRIBUTION
The contact area between DELTA-TERRAXX and the surface is approx. 80%. So, the seal is optimally protected from punctiform loads from the filling material.
IMPACT SOUND REDUCTION OF UP TO 32 DB
At impact sound tests based on DIN EN ISO 10140, DELTA®-TERRAXX was applied between the waterproofing and the covering or gravel bed. The Rhein Main University of Applied Sciences confirms an impact sound reduction of up to 32 dB. An impact sound reduced by only 10 dB for the human ear feels like a airborne sound reduced by 50%.
NO SILTING UP OF THE KNOB STRUCTURE
Thanks to its special structure and its characteristic opening width of 140 μm, the laminated geotextile is extremely filter-stable and prevents the dimpled sheet from silting up.
