The lightweight nature of Terrain FUZE allows the product to be installed quickly and efficiently, giving direct, resource-saving benefits to specifiers and installers.

HDPE offers exceptional performance above and beyond traditional pipe materials including:

  • Versatile application
  • Highly resistant to impact even at low temperatures
  • Highly resistant to chemical agents
  • Corrosion resistant
  • Abrasion resistant
  • Lightweight and easy to install
  • Ideal for pre-fabrication
  • Suitable for use with Terrain HydroMaxTM Siphonic System

Terrain Acoustic dB12

Acoustic drainage system with superior performance
We all know how much noise water can make when it travels through a building and hovv intrusive this sound can be. In endeavouring to meet sound controls within Building Regulations, additional materials and labour are required, increasing the cost and time on site. Terrain Acoustic dBl2 is a complete acoustic drainage system designed to reduce the effect of noise.

Terrain Acoustic dBl 2 multilayer drainage pipe with acoustic fittings creates a high quality durable and reliable system developed specifically to meet construction requirements for increased level of soundproofing, and ideally suitable for: Mixed development, Hospitals, Hotels, Schools, Commercial applications.

Advanced technology and performance
Terrain Acoustic dB12 has been specifically developed for acoustic soil applications, with four sizes of pipe from 40mm - 160mm and a comprehensive range of fittings to provide complete solution for acoustic amnagement of soil pipes.

Terrain Acoustic db12 multilayer pipe and acoustic fittings have been tested to the most recent European accreditations for airborne and impact noise, at the highly respected Fraunhofer Institute in Stuttgart.
