The Problem

Drainage systems using gravel and sand require large volumes of material, heavy-duty transportation, and time-consuming installation. Low-quality geotextile mats, made from a cotton blend, degrade rapidly in acidic soils or when exposed to chemicals, compromising the entire project.

A Solução Wavin Bidim© Geotextile

Bidim© Wavin is made of 100% pure needle-punched polyester—with no cotton blend. It offers indefinite resistance to acids, alkalis, oils, solvents, and roots. Full traceability is ensured by the original Bidim brand, guaranteeing the quality the market demands. Costs are reduced by up to 25% compared to traditional systems using gravel or sand.

Frequently Asked Questions

Dúvidas comuns sobre o Wavin Bidim© Geotextile

Bidim is a needle-punched nonwoven fabric, ideal for filtration and drainage because it maintains uniform porosity. Woven geotextiles are better for soil reinforcement, but they filter less effectively. Bidim combines both functions in its RT series.
Yes. Bidim sleeves are available in sizes ranging from 2 to 10 inches, ready to be wrapped around drainage pipes. A more practical alternative is to use Techdreno KC, which comes with an integrated geotextile.
GT for general filtration and drainage, RT for soil reinforcement with high tensile strength (up to 31 kN/m), CC for concrete curing (reusable at least 4 times), and VP as a waterproofing membrane.
Yes. Because it is made of 100% polyester, Bidim is resistant to acids, alkalis, oils, solvents, and biological agents in the soil. It does not decompose due to microorganisms or roots.
Varies by product line: from 4.7 kN/m (GT7, light filtration) to 31 kN/m (RT31, heavy reinforcement). ExtraDren withstands 200 kPa of compression for subdrainage.
Yes. Bidim is widely used in landfills as a filtration, separation, and protective layer for geomembranes. Chemical resistance is essential in this harsh environment.
