Soil - Acoustic Wavin AS

When low noise is a building requirement, the Wavin AS system gives the best performance of any plastic pipe. As the world leader, it is the most frequently installed low noise system. Wavin offers advanced tools for noise prediction too, helping ensure that your choices meet the required sound level.

The system delivers significant sound reduction over standard soil systems. Its mineral-reinforced molecular material, Astolan®, can absorb airborne, structural and impact sound.

Installation is fast and easy which saves time and cost, especially compared with traditional sound insulating techniques such as cast iron. Mineral wrapping is not required unless stipulated as Robust Details.


Special Advantages

 Lightweight compared with cast iron, yet extremely robust and resistant to corrosion.

Manufactured from sound-reducing material.

No need for mineral wrapping.

Push-fit technology saves installation time and cost.


Features and Benefits – In Service

Resistant to hot water: operational temperature capability of up to 95˚C short-term (90˚C long-term)

Extremely robust: corrosion-resistant.

Waste water drainage capability between pH2 and pH12.

Smooth inner surface: resistant to build-up of internal deposits.



Soil stacks in multiple-storey buildings requiring noise insulation.

This system is also ideal for suspended pipework.

System Information

Noise reduction

Wavin AS reduces noise levels for soil and waste better than any other system. We achieve this through wall thickness and density. At 5.3mm for 110mm pipes and with a density of 1.9kg/dm3, Wavin AS outperforms all other systems on the market.

Better than cast iron

Wavin AS beats cast iron since it has in most situations superior noise insulating properties. It is lighter and easier to install. Its secure push-fit rubber connections and corrosion-free components deliver a long lifetime of trouble-free service.

No guesswork

Wavin gives you the tools and support you need to accurately predict the noise levels of any soil and waste installation. Our tools have been developed by a specialist acoustic engineering company. They measure more than ten variables covering both airborne and system-borne sound.

Where to use Wavin AS

Wavin AS has become the system of choice wherever silent operation matters. It is used in apartments and residential homes; in schools and universities; hospitals, hotels and offices. It’s even used in Milan’s La Scala, the World’s most famous opera house.

Structure and airborne sound

Wavin AS achieves optimal reduction of airborne sound thanks to its high mass and wall thickness and of structure-borne sound thanks to the low elastic-modulus of its flexible PP material and the special couplers.

World leader

Wavin AS is the world’s first choice of low-noise soil and waste. Over 25 years, this polypropylene system has become the first choice of architects and building system designers.

What’s next?

Wavin AS low noise soil and waste systems are part of an extensive range of products for domestic and commercial environments. They work as well in gravity-fed rainwater systems as in environments such as commercial kitchens, with their high temperatures and greasy water.
