TekDrain YKL 500 is a high-performance drainage and protection board manufactured from high-density polyethylene (HDPE), offering excellent resistance against root penetration and decay. The product separates the structure from the soil, protects retaining walls against water and moisture, and prevents mechanical damage to waterproofing systems caused by backfilling operations.
Thanks to its studded structure, TekDrain YKL 500 provides both effective drainage performance and mechanical protection in underground construction applications.
TekDrain YKL 500 combines waterproofing protection, drainage, and pressure distribution functions with its studded HDPE structure.
The air gaps between the studs allow wall ventilation, maintain moisture balance, and help reduce hydrostatic pressure. Its high mechanical strength provides reliable protection against heavy soil loads and external impacts.
With a compressive strength above 200 kN/m², TekDrain YKL 500 provides reliable protection against heavy soil pressure and mechanical loads.
Prevents punctures and damage to waterproofing membranes during soil filling and construction operations.
The studded structure distributes soil pressure evenly, reducing point loads and extending the service life of insulation layers.
The channels between the studs allow water to flow safely along the wall surface, reducing hydrostatic pressure.
The air gap created between the studs supports ventilation and helps maintain moisture balance within the structure.
The HDPE structure provides:
Its lightweight and flexible structure enables fast and practical installation on various surfaces.
Store vertically and protect from direct sunlight.
Under suitable storage conditions, the product maintains its performance indefinitely.
It is used for drainage and protection purposes in foundations, retaining walls, underground structures, parking areas, and green roof systems.
According to the TS EN 826 standard, the compressive strength is above 200 kN/m².
The HDPE core is waterproof. The studded structure allows controlled water drainage between the channels.
The studs should face toward the waterproofing surface to create an effective drainage gap.
Yes. The HDPE structure is resistant to plant roots and decay.
TekDrain YKL 500 provides long-lasting structural protection by combining high mechanical resistance, effective drainage capability, and waterproofing protection in a single durable HDPE drainage solution.
