What is the difference between a drainage board and a geomembrane?
A drainage board creates a path for water movement. A geomembrane provides a barrier to water flow. A project may require both as part of a complete system.
What does nonwoven geotextile do?
It is used for filtration, separation and protection. Material selection depends on the soil, loading and drainage conditions.
Which materials are used around foundations?
Depending on the project, a coordinated system may use drainage board, filter geotextile, waterproofing and a collection drain. Review the wall design and drainage outlet before selection.
How are roof-garden layers arranged?
A typical planting zone includes growing medium, filter geotextile, drainage and water storage, protection, waterproofing and the structural slab. The final arrangement follows the project design.
Can dimensions and specifications be customized?
Available options depend on the product and project requirements. Share the required thickness, height, width, length, material properties and quantity for review.
Which documents should I send for a quotation?
Send application details, drawings or a specification sheet, dimensions, quantities, delivery destination and any packing requirements.
How are minimum quantity and delivery time confirmed?
Minimum quantity and delivery arrangements are confirmed after reviewing the product, specification, quantity and destination. Contact the team for your project.
