Water-resistant underlayment with sound absorbing qualities

Shumanet-100Hydro is a dual–purpose material. It provides waterproofing for floating floors and significantly reduces shock noise.

It effectively reduces the shock noise level by up to 24 dB

Shumanet-100Hydro is used as an elastic layer in a sound insulating floating floor construction.

Acoustic felt retains its elastic properties under load and increases the shock noise insulation level of the floor structure by 24 dB.

The stability of the Shumanet-100Hydro characteristics is confirmed by long-term use of the material in construction and regular measurements at existing facilities.

Professional Waterproofing Material

Shumanet-100Hydro is designed to provide effective shock noise insulation in rooms prone to leaks, such as bathroom, kitchen, water closet.

The top layer of the underlayment is made of a reinforced polymer-bitumen membrane that protects the floor surface from leaks. Adding polymers to the bitumen binder provides high temperature resistance, durability, and strength of the waterproofing layer.

Features of the material usage, ready-to-use soundproofing structures and examples of implemented projects can be found in the "Usage" tab.

Storage

Shumanet-100Hydro material should be stored in an upright position in one row in compliance with fire safety rules and away from any precipitation and groundwater.

Features of the material usage

Shumanet-100Hydro, unlike other waterproofing materials, does not require surfacing, but simply fits on the flooring surface as a single sheet. The bituminous surface of the material must face upwards, while the edges must overlap one another. The joints between the sheets of material should be sealed by softening the bitumen with a heat gun or a narrow flame gas burner.
