NOVERA HydroRepair

NOVERA HydroRepair

A new-generation two-component elastic waterproofing membrane.

Flexible like rubber. Strong like armor.

The foundation of every professional NOVERA system.

NOVERA HydroRepair is a silent guardian between water and the structure.

A liquid material that transforms into a cohesive elastic membrane; it follows details, bridges cracks, and creates a seamless waterproof shield.

Its core consists of modern polymers and reinforcing fibers that together give the membrane high mechanical resistance and the ability to withstand cyclic structural movements as well as long-term water exposure.

BENEFITS

Extreme waterproofing performance

Certified resistance up to 25 m water column (corresponds to real conditions for sealing swimming pools and strong static water pressure).

Two-component elastic membrane with elongation > 300%

Bridges cracks even under repeated cyclic movement.

Reinforced with synthetic fibers

Enhanced mechanical resistance against impact, point loads, and erosion.

Excellent adhesion to a wide range of substrates

Concrete, ceramics, metal, old cohesive surfaces, asphalt with mineral finish.

Resistance to frost, UV radiation, chemicals, and mechanical wear

Bridges cracks and withstands structural expansion and contraction

Ideal for real-world structures with shrinkage/expansion movements.

Suitable for damp and wet environments

Basements, showers, bathrooms, swimming pools (subject to system validation and approved technology).

System base for NOVERA Reflex

A perfect substrate for subsequent thermo-reflective layers.

TECHNOLOGY

WHAT IS NOVERA HYDROREPAIR

NOVERA HydroRepair is a two-component system (A + B),
designed as a “liquid reinforced rubber.”

Component A (liquid polymer base)

Modern elastomeric polymers that, after curing, provide a thixotropic,
cohesive, and flexible matrix. They ensure adhesion, elasticity,
UV resistance, and frost resistance.

Component B (dry mix)

Mineral fillers, composite binders, and synthetic fibers.
After mixing, they enhance mechanical properties, increase strength,
and improve crack-bridging capability.

Resulting layer

A homogeneous, watertight, elastic membrane with high cohesion,
capable of accommodating structural movements without delamination.

Physical principles

Elasticity from the polymer + strength from fibers →
a membrane that is both watertight and mechanically protective.

BASIC APPLICATIONS

Intended for

roofs (as a base leveling and sealing layer before final surfaces)
terraces and balconies (including application under tiles)
water features: pools, tanks, and shower areas (after verifying type and certification for pressure-water resistance)
basements, underground areas, remediation of damp structures
detail repairs: penetrations, pipe/duct pass-throughs, parapets, connections, expansion joints

Suitable substrates for HydroRepair

concrete, cement screeds
ceramic tiles (joint pre-treatment)
mineral plasters and masonry
metal elements (anti-corrosion pre-treatment)
cohesive asphalt/bitumen layers with mineral surface finish
older cohesive coatings (after an adhesion test)

Note: For highly absorbent or contaminated substrates, a primer / pre-treatment is recommended (NOVERA PNT or another system solution).

APPLICATION

Substrate preparation

The substrate must be solid, dry (or with residual moisture within permitted limits), cohesive, and free of dust, grease, and loose particles.
Old coatings and non-cohesive layers must be removed.
Cracks wider than recommended must be filled; sharp edges should be smoothed.
Highly absorbent substrates → primer application with NOVERA PNT according to the specified system technology.

Component mixing

Mixing ratio A : B = 1 : 3 (by volume/weight according to the supplier’s specific formulation).
The mixture must be thoroughly whisked/mixed at low speed to achieve a homogeneous consistency.
Working time (pot life): approx. 60 minutes at +20 °C (temperature affects processing time).
At lower temperatures, shorten processing time; at higher temperatures, increase material consumption speed.

Application

Tools: stainless steel notched trowel or stainless steel float; application by spraying or cement pump is possible for larger areas (subject to approval).
Recommended application: 1–2 layers (depending on required thickness and load). For filling and thicker layers, multiple coats may be applied with technical breaks.
Recommended consumption: 1.5–2.0 kg/m² (depending on required layer thickness and substrate).
Interval between layers depends on temperature and humidity – typically after initial curing (waiting for so-called “tack-free” state, usually 5–8 h).
Walkability: 5–8 h after application (at +20 °C; depends on thickness and climate).
Full waterproofing performance after final curing (typically 24–72 h depending on thickness and conditions).

Temperature and climatic limits

Application temperature range: +5 °C to +40 °C (substrate and ambient temperature).
Relative humidity: ideally < 80%; high RH increases curing time.

WHY HYDROREPAIR IN THE NOVERA SYSTEM

Base structural layer

HydroRepair serves as a solid, flexible, and waterproof base beneath NOVERA Reflex or other surface coatings.

Remediation and preparation

Ideal for the renovation of old roofs, repair of details, crack bridging, and surface leveling.

Compatibility

Designed to be fully compatible with:
NOVERA Spider (detail reinforcement)
NOVERA PNT (penetration primer for absorbent or problematic substrates)
NOVERA Reflex as the final thermo-reflective layer

PRACTICE AND REAL-WORLD APPLICATIONS (examples)

Repair of damaged roofs prior to NOVERA Reflex application

Leveling and sealing of details without the need to dismantle the roofing system.

Terraces and balconies under tiled finishes

HydroRepair + geotextile + tiles without negative impact on the underlying structure.

Waterproof basements and underground areas

System application including detailing of joints and penetrations.

Swimming pools and water features

Following specific validation and strict adherence to technological procedures (chemical resistance control, operating temperature, and protective coverage).

Packaging:

Standard A+B combination (e.g. 20 kg + 6 kg); other configurations possible for large orders.

Storage:

Dry, temperature-controlled area, +5 °C to +30 °C.

Shelf life (in packaging):

Typically 12 months if storage conditions are met (verify with the manufacturer).
