Tektoseal® Clay

High-performance sealing for groundwater protection, contaminated site remediation and hydraulic engineering

Tektoseal Clay is the result of continuing development of industrially manufactured sealing systems, which has taken into account the latest findings in research and development. As a result of many years of experience in manufacturing bentonite composites, with Tektoseal Clay HUESKER has succeeded in developing a high-performance product with the best possible sealing and installation features which meet current recommendations and guidelines.

Tektoseal Clay is a highly developed, perfectly matched multi-component system consisting of extremely robust geosynthetics containing sodium bentonite granulated material. Using the latest production equipment these components are processed with a special precision needling technique to produce a homogeneous sealing layer across the entire surface area of the liner.

Tektoseal Clay may be used as fluid barriers in the construction of tunnels and deep founded underground structures and the intended use of these products is to control the leakage of water through the construction wall. Tektoseal Clay is preferred in use in pressurized increased water levels and all earth connected concrete walls in the modern building and civil engineering structures.

Tektoseal Clay consists
of three components:

 

  1. non-woven fabric as top layer
  2. sodium bentonite granules as a gasket
  3. high tensile fabric as carrier material

Our product variants

Tektoseal Clay NA is the consistent further development of industrially manufactured sealing systems taking into account the latest findings from research and development. Due to its special manufacturing process, the highly developed clay seal is not only particularly economical, but also ecological. The bentonite mat, less than 10 mm thick, achieves at least the same sealing effect as a conventional clay seal (50 cm thick). In addition, permanent monitoring during production ensures a consistently high level of quality in the building.

Special advantages:

  • Insensitive to settlement
  • Self-healing effect against mechanical damage
  • Durable due to high chemical resistance
  • Permittivity 3 -10-9 1/s
  • Water permeability coefficient k = 3 -10-11 m/s

Tektoseal Clay RM solves the challenges of sealing ponds for industrial residuals worldwide. Due to the high pH value and the high electrical conductivity, bauxite residues place considerable demands on the sealing properties of bentonite. The sealing layer integrated in Tektoseal Clay RM consists of a tailor-made mixture of various  bentonites without any polymer additives. This eliminates concerns about product life caused by polymer loss due to wash-out and polymer degradation over time.

Special advantages:

  • Unique, strongly swelling bentonite mixture
  • long-term barrier function
  • High chemical resistance
  • Self-healing effect against mechanical damage
  • Tailor-made product configuration for on-site requirements
