Terraces and balconies with polyurea – results you can see

Does this sound familiar?
Water always finds a way. We find it faster.
Choose what is happening in your building and we’ll show you how we solve it.
Damp basement, moisture in the walls
Damp walls, efflorescence and a musty smell. We create a chemical damp-proof course (DPC) by injecting silicates or creams.
Injection waterproofingLeaking terrace or balcony
Water gets under the tiles and runs down to the floor below. A seamless polyurea coating seals the surface.
Polyurea coatingsCracks in concrete
Water seeps through a crack. Resin injection provides a flexible seal for both damp and dry cracks.
Injection waterproofingFlat roof leak
A stain on the ceiling, but no visible source. We pinpoint the leak instead of stripping the roof covering blindly.
Leak detectionWater in an underground car park
Leaks through walls, joints and the floor. PENETRON® crystalline waterproofing or a polyurea coating can help.
Crystalline waterproofingLeaking expansion joint or pipe penetration
Water in an expansion joint damages the structure. We seal expansion joints and pipe penetrations with flexible materials.

Complete waterproofing for buildings
JAWEX-IZOLACJE SP. Z O.O. solves leak and damp problems in houses, blocks of flats, industrial halls and industrial facilities.

Leak detection
Flat roof leaks: the electrical resistance method (dry, no flooding of the roof), electric field vector mapping and thermal imaging. Periodic inspections and roof handovers.
Service details
Polyurea coatings
Spray-applied, seamless waterproofing for terraces, balconies, flat roofs and garage floors.
Service details
Injection waterproofing
Sealing cracks, walls and joints with resins, acrylic gels, creams and silicates. Also curtain injection without excavation.
Service details
Crystalline waterproofing
The PENETRON® system: self-sealing concrete and long-lasting sealing of structures, including from the inside.
Service details
Expansion joints and pipe penetrations
Flexible sealing of leaking expansion joints and of pipe and service penetrations through walls.
Service detailsHow we work
Find → Fix → Check → Monitor
We look for the cause first and only then do we seal. That way you pay for a repair that works.
- Diagnosis
Find
An on-site inspection to establish the cause. We locate flat roof leaks using the electrical resistance method, vector mapping or thermal imaging.
- Sealing
Fix
We match the technology to the cause: polyurea, injection, PENETRON® or sealing of expansion joints and penetrations.
- Verification
Check
We show you the result. On a flat roof, watertightness can be checked with the same method we used to find the leak.
- Inspections
Monitor
Periodic watertightness inspections, so that a minor defect does not turn into a flood.
Who we help
From a terrace at home to the roof of an industrial hall
Houses and flats
Basement, terrace, balcony, garage. We will come out, assess the problem and choose a solution that fits it.
- terraces and balconies
- basements and foundations
- garages and floors
Homeowners’ associations and property managers
Roofs of blocks of flats, underground car parks, expansion joints and pipe penetrations in common areas.
A plan for the annual meeting: the annual financial plan, including repairs, is adopted by the owners’ meeting, which the board must convene no later than the first quarter of the year (Article 30 of the Polish Act on the Ownership of Premises). A leak diagnosis before the meeting gives you a specific item for the plan.
Leak detectionIndustrial halls, warehouses and businesses
Large flat roofs on industrial halls, warehouses and office buildings. Fast leak location without stripping the roof covering.
Inspections twice a year: buildings with a footprint of more than 2,000 m² and structures with a roof area of more than 1,000 m² must be inspected by 31 May and by 30 November (Article 62 of the Polish Construction Law).

Periodic inspections
Check your roof before a stain appears on the ceiling
A preventive roof check reveals the spots that could cause a leak over time. You save yourself the time and stress of hunting for a leak after the fact.
- flat roofs of houses, blocks of flats, industrial halls and office buildings
- terraces, green roofs and inverted roofs
- roof handover inspections for investors and developers

Questions and answers
Frequently asked questions
How do you find a leak in a flat roof if you can’t see it?
We use the electrical resistance method, electric field vector mapping and thermal imaging. They let us pinpoint leaks without stripping the roof covering. We mark the leak points on the roof with fluorescent paint and then propose a repair method.
Do walls have to be chiselled or foundations dug out?
Often not. Pressure injection is a non-invasive method: the injection material is introduced through a series of drilled holes. Curtain injection makes it possible to add external waterproofing to existing walls without excavating them, and the PENETRON® system can also be applied from the inside. We choose the right method after an inspection.
Which surfaces is polyurea suitable for?
Terraces and balconies (concrete, porcelain stoneware, terrazzo, bitumen), flat roofs covered with roofing felt, garage floors, as well as water tanks and sewage treatment tanks. Polyurea adheres well to concrete, steel and ceramic tiles.
When can the terrace be used after the polyurea has been sprayed?
Polyurea cures quickly, and the surface is ready for use as soon as the application is complete.
How does PENETRON® crystalline waterproofing work?
Active compounds react with water and the components of concrete to form insoluble crystals. These fill capillaries and micro-cracks up to 0.4 mm wide, while the concrete can still breathe. If a crack and moisture appear in the future, the crystals grow again and the concrete seals itself.
Do you carry out roof inspections and handover inspections for investors?
Yes. We carry out periodic roof watertightness inspections before a leak appears. We help investors and developers with roof handover: we find membrane defects and causes that are invisible to the naked eye, such as mechanical damage, overheated roofing felt or a waterproofing layer that is too thin.
Where do you work?
Across four whole provinces: Lubelskie (including Lublin, Puławy, Chełm, Zamość, Biała Podlaska), Mazowieckie (including Warsaw, Radom, Siedlce, Płock), Świętokrzyskie (including Kielce, Ostrowiec Świętokrzyski, Sandomierz) and Podkarpackie (including Rzeszów, Stalowa Wola, Mielec, Przemyśl, Krosno). Our base is in Kalinówka near Lublin.
What should I prepare before getting in touch?
A short description is enough: where the water appears, when (after rain, during a thaw, all the time), what kind of building it is and in which town. A photo sent via the form helps a lot with the initial assessment.
