Hydraulic and Mining

The BMI Siplast elastomeric bitumen membranes combine the advantages of traditional materials like bituminous binders with the advantages of modern materials, in particular polymers and geotextiles.

Decorative ponds, natural swim ponds, water features, tanks

  • Flexibility ideal for decorative water features as they can easily be shaped to the needs of the design.
  • Resistant to cracking and have a high level of durability to UV-exposure.  

Mining applications, tailing containment, heaped leach pads, water management

  • Ease of installation - even under harsh conditions makes them a suitable choice.

Canal lining, channel lining, swale drains, ditch lining, water conveyance, aqueducts

  • Reliable canal liner for exposed applications
  • The only geomembranes for which there is a specific standard written for their use as exposed canal liners (see ASTM D 2643).

BGM

Farm dams, water storage dams, effluent ponds, liquid containment ponds, aquaculture

  • Superior performance in exposed applications and its resistance to stress cracking give designers the confidence they need when specifying a lining solution for a critical project.

Detailing and maintenance

  • Excellent adhesion to its support creates a reliable and durable waterproofing connection.

Installation of Teranap

  • Easy to install and do not require any specialised thermal welding device or equipment. With training, it is easy for any semi-skilled labourer to correctly install the product.
  • The high angle of friction allows for safe and easy movement by the installers both up and down the slopes being lined with the Teranap BGM.
