Hydro-soundproofing floor with the use of Shumanet-100Combi
Thickness: 65 mm
ΔLnw ≈ 26 dB
When applied?
- If there is a need to reduce noise from footsteps and attain a reliable waterproofing. Most often used in wet premises.
Overview
The structures of soundproof floating floors are used in construction and renovation of buildings of any type and purpose for insulating floor from impact noise and providing additional reduction of airborne noise. It is necessary to take into account the change in the thickness of the soundproof layer when the workloads on the base change in the process of designing the structures of floating floors.
The structure is used in rooms with increased requirements for waterproofing. The construction consists of a layer of reinforced cement-sand screed with a thickness of at least 60 mm laid on the soundproofing material Shumanet-100Combi.

You can calculate the approximate estimate of sound insulation in your case. To do this, it is enough to enter the surface area that is supposed to be isolated. The estimate is calculated with a 5% margin, as well as taking into account rounding to whole packages. Please note that the estimate is approximate, since it does not take into account the individual characteristics of your premises.

Specialized accessories:
- The Shumanet-100Combi material should be laid at room temperatures above +5 °C.
- Before rolling out the Shumanet-100Combi sheets, the flooring underlay should be carefully swept from sharp burrs, protruding fittings and construction debris to prevent them from getting between the underlay and material sheets.
- The Shumanet-100Combi material should be rolled out and cut in accordance with the specified dimensions in such a way as to completely cover the floor area and at the same time ensure that the material is overlapping the walls or columns.
- The bituminous surface of the material should face upwards, and the edges should overlap one another. For this purpose, each roll has an approximately 93 mm wide overlap of bituminous waterproofing layer on one end. In addition, the edges of the material should overlap the walls or columns above the level of the screed to avoid hard contact between the screed and other building structures. If necessary, to prevent shifting during screed installation, the material should be secured with bituminous self-adhesive tape or a bitumen overlap should be fixed on the wall using a heat gun. The joints between the sheets of material also should be sealed by softening the bitumen with a heat gun. After installing the screed, the edge of the Shumanet-100Combi material should overlap the wall (column) to the height of 100 mm.
- Wrapping (bypassing) of such elements as door openings, corners, pipe outlets, internal utility lines and other room finishing elements with the Shumanet-100Combi material should be provided. Shumanet-100Combi should be wrapped around the protruding element and fixed to the element along the upper edge using bituminous self-adhesive tape or a heat gun.
- After laying the Shumanet-100Combi lining material, a 60 mm thick sand cement screed should be made of grade M-300 sandcrete or ready-mixed concrete.
- When installing the screed, it should be reinforced with a metal mesh with 50 x 50 mm cell size and 4 mm rod diameter. The mesh should be placed in the screed layer not lower than 20 mm below its lower level and not higher than the screed center line. The mesh should be laid with joint overlapping by 100 mm, and fastened with tie wire every 200 mm.
- The grout surface should be leveled with a screed board. For large floor surfaces, leveling screed should be made in sections up to 30 m2 with the mandatory installation of expansion joints.
