TekDrain Geo 10/400 Drainage Board | HDPE + PP Geotextile Drainage Solution with 400 kN/m² Compressive Strength

TekDrain Geo 10/400 Drainage Board

Durable Drainage Solution with HDPE and Geotextile

TekDrain Geo 10/400 is a composite drainage board manufactured with a high-density polyethylene (HDPE) core and an integrated polypropylene (PP) geotextile filter layer. With a compressive strength of 400 kN/m² and high drainage capacity, it provides long-term protection in demanding applications such as tunnels, bridges, parking structures, and infrastructure projects.

Its studded structure enables efficient water drainage, while the geotextile layer prevents soil particles and debris from entering and blocking the drainage channels.

Product Description

TekDrain Geo 10/400 is a professional drainage system combining a studded HDPE sheet with a PP geotextile filter layer.

• Studded structure: Allows water to flow efficiently along the surface and into drainage channels.
• Geotextile filter layer: Allows water passage while preventing soil and particles from entering the drainage system.
• Hydrostatic pressure control: Protects foundation and retaining wall waterproofing systems, extending structural service life.

Product Features and Benefits

High Compressive Strength

With a compressive resistance of 400 kN/m², TekDrain Geo 10/400 maintains its structure under heavy loads without deformation.

High Drainage Capacity

Provides rapid water evacuation with a drainage performance of approximately 17,300 L/h/m, reducing hydrostatic pressure on structures.

Geotextile Filtration Protection

The integrated geotextile filter prevents soil particles from entering the drainage channels, minimizing clogging risks.

Durable HDPE Core

The HDPE structure offers excellent resistance against:

• Chemicals
• Root penetration
• Biological degradation
• Moisture exposure

Improved Moisture Management

The air cavity created by the studded profile supports ventilation and helps maintain moisture balance around structures.

Easy Installation

The roll format enables fast and practical installation over large surfaces.

Long-Term Performance

Designed to maintain drainage efficiency and structural performance even under demanding environmental and mechanical conditions.

Installation Information

Surface Preparation

• The surface should be clean, flat, and dry.
• Sharp edges and protrusions must be removed before installation.

Placement

• Install with the geotextile layer facing outward toward the soil.
• Rolls should overlap by approximately 10–15 cm.

Fixing

• Secure the drainage board using suitable plastic anchors or drainage fixing accessories.
• Ensure proper continuity at joints.

Backfilling

• Backfill carefully using material free from large stones or sharp objects to prevent damage to the drainage board.

Packaging and Storage

Packaging

• Roll length: 12.5 m
• Roll width: 2.0 – 2.4 m
• Supplied in roll format

Storage

Store on a flat surface in a dry area protected from direct sunlight.

Shelf Life

Under proper storage conditions and without mechanical damage, the product maintains its performance indefinitely.

Frequently Asked Questions (FAQ)

Where is TekDrain Geo 10/400 used?

It is used in road drainage systems, tunnels, bridge decks, underground parking structures, and high-load construction applications requiring reliable drainage protection.

What materials is the product made from?

The drainage sheet is manufactured from HDPE, while the filtration layer is made from PP geotextile. Both materials are resistant to decay, roots, and chemicals.

What is the compressive strength of TekDrain Geo 10/400?

The product provides a compressive strength of 400 kN/m² (approximately 40 tons/m²).

Is the product waterproof?

The HDPE core is waterproof. The geotextile layer allows only water filtration while preventing soil particles from entering the drainage system.

What is the operating temperature range?

The product can be used between -40°C and +80°C.

TekDrain Geo 10/400 provides a high-performance, long-lasting, and reliable drainage solution with its heavy-duty HDPE structure, integrated PP geotextile filter, and 400 kN/m² compressive strength, making it ideal for demanding infrastructure and construction projects.
