PPECOFORTE
PPEcoforte®
Three-layer PP-HM buried sewer system · Ø 110 mm - Ø 500 mm · ring stiffness up to SN16
PPEcoforte® is a three-layer buried sewer system made of high-modulus polypropylene (PP-HM) for non-pressure waste and combined water drainage, buried inside and outside the building (UNI EN 13476-2). The outer layer is UV-stabilised and the smooth bore ensures optimal flow.
Product information
- Fast installation: Light components speed up and simplify the installation work.
- Reliable joints: The two-component locking seal stays firmly in its groove, also during installation.
- Wide size range: Pipe sizes Ø 110 mm - Ø 500 mm and a comprehensive range of fittings and couplings.
- Durable construction: The three-layer structure gives excellent impact resistance, also at low temperatures.
- Chemical resistance: Withstands chemicals in the pH range 2–12. The smooth inner surface reduces deposit build-up.
Applications: Buried gravity sewers for buildings and municipal networks, for domestic wastewater (grey, black and combined) and agricultural wastewater. The system consists of UD-class structural pipes and fittings to UNI EN 13476:2018, suitable for buried drainage inside and outside buildings.

POLIMASK
Polimask™
Patented watertight entry system for cable-duct inspection chambers
Polimask™ is Valsir's patented system for building inspection chambers for multi-duct cable packages. The polypropylene mask aligns the ducts and acts as a casting mould during concreting. The duct penetrations, alignment and watertight sealing are achieved in the same work stage as the chamber is cast.
Product information
- Entries, alignment and sealing in one work stage during casting
- Double O-ring couplings: watertightness between mask and ducts
- Polimask 110: wall thickness 150–370 mm · Polimask 160: 150–580 mm
- Masks combine with centring elements into larger chambers
- Watertightness to the chamber via an expanding waterstop seal
Cable-duct inspection chambers for power and fibre-optic networks in municipal and infrastructure works. Polimask™ ensures watertight duct penetrations also where conventional solutions do not meet watertightness requirements.
Technical data
| Models | Polimask™ 110 (ducts Ø 110 mm) · Polimask™ 160 (ducts Ø 160 mm) |
| Wall thickness | Polimask 110: 150–370 mm · Polimask 160: 150–580 mm |
| Construction | polypropylene mask · double steel frame · protection plugs |
| Sealing | double O-ring couplings to ducts · hydro-expanding waterstop to the chamber |
| Compatibility | PPEcoforte® cable-duct packages · Polimask 110 and 160 combinable |

Aquanest
Stormwater infiltration and attenuation system · storage ratio up to 96 % · load class SLW 60
Aquanest is Valsir's infiltration and attenuation cell system for efficient and sustainable stormwater management (SuDS). Cloudburst runoff is infiltrated, attenuated and discharged in a controlled way. The cells are made from a blend of recycled polypropylene and mineral fillers, and are 100% recyclable at the end of their service life.
Product information
- Storage ratio up to 96 %: Equal to 960 litres of stormwater per cubic metre of cells.
- Load class SLW60 (60 t) with over 80 cm cover depth
- Recycled polypropylene + mineral fillers · 100 % recyclable
- Serviceability: Two integrated inspection channels allow CCTV survey and jetting in both directions.
- Connection for D315/D400/D500 pipes · cuttable to size
Aquanest suits stormwater infiltration and attenuation structures in yard, street and district construction, such as infiltration fields and attenuation basins. The system helps prevent urban flooding and reduces the load on the stormwater network. Thanks to the stackable structure, one 70 m³ load covers up to 400 m³ of cells, which makes transport more efficient and cuts logistics costs.
Technical data
| Cell size | 790 × 790 mm |
| Storage ratio | up to 96 % (960 l/m³) |
| Load class | SLW60 (60 t), cover depth over 80 cm |
| Material | recycled PP + mineral fillers · 100 % recyclable |
| Inspection | two integrated channels for CCTV and jetting |
| Connections | to sewers D315/D400/D500 |

Birdie - floating cover modules
Covering and protecting basins and slurry tanks
Product information
- Protection and reduced evaporation: Floating modules cover basins and slurry tanks, reduce water evaporation and prevent the growth of algae, bacteria and harmful organisms.
- Emission reduction: Cuts ammonia (NH₃) and methane (CH₄) emissions and supports compliance with BAT (Best Available Techniques) requirements.
- Light and durable construction: The three-layer PE-HD structure is blow moulded, which reduces material use by up to 70 % compared with injection moulding
- Stable buoyancy: The module interior acts as water ballast, and the hexagonal flotation chamber makes the structure unsinkable.
- Fast, low-cost installation with no maintenance
Applications: covering and protecting basins, reservoirs and slurry tanks; agricultural slurry tanks, which regulations require to be covered by 2030 to limit ammonia, methane and odour emissions; protecting water reserves from evaporation.
