The choice directly depends on the property's location and solar exposure. For terraces and flat roofs in Lisbon or the Algarve, we frequently utilize liquid polyurethane membranes or high-UV-resistance bituminous membranes. For basements and foundations with hydrostatic pressure, cementitious mortars or crystallization systems provide the most reliable moisture barrier.
Every Surface Water Can Get Through
TERRACES, ROOFS, BASEMENTS, POOLS AND BALCONIES
Every surface holds water differently: a flat terrace pools it, a basement wall fights pressure from the soil, a pool holds it under constant load. Each one needs a different membrane, a different detail at the joints, and a different approach. At Obra É Fácil, we match the system to the surface and where the water comes from. Pick the area below to see how we handle it.
Roof and Terrace Waterproofing
Application of technical membranes that guarantee absolute protection against upper-level leaks. This solution preserves the building’s structure, preventing slab degradation and ensuring a dry interior even under extreme weather conditions.
Airtightness for Balconies and Patios
Specialized treatment for exposed outdoor surfaces using systems with high resistance to UV rays and foot traffic. We utilize liquid or bituminous membranes that eliminate cracks and protect lower areas from chronic infiltration.
Basement and Underground Parking Insulation
Technical solutions to combat humidity from hydrostatic pressure or capillary action in below-ground areas. We implement watertight barriers that prevent water entry, ensuring the safety and usability of subterranean spaces.
External Facade Waterproofing
Protection of exterior walls against driving rain through water repellents and breathable technical coatings. This intervention prevents moisture from penetrating the masonry, stopping mold growth and plaster detachment.
Swimming Pool and Tank Watertight Coating
High-performance systems ensuring total water containment and resistance to constant pressure. We use certified materials that guarantee structural durability and perfect adhesion for the final finish, whether ceramic or continuous.
Wet Area Waterproofing (Bathrooms and Kitchens)
Application of protective barriers beneath the final tiling in bathrooms and kitchens. This process is essential to prevent damage to adjacent structures and ensure that bathing areas remain completely watertight long-term.
Expansion Joint and Crack Treatment
Critical interventions at structural movement points to ensure the continuity of the waterproof barrier. We utilize elastic sealants and technical bands that absorb building vibrations without compromising protection against water ingress.
01
Protects the foundation and structure from corrosion and concrete damage, so the building stays sound for the long term
02
Cuts down capillary moisture and condensation, for a healthier home with far less mould and fungi
03
A dry, well-protected building holds its value better and is easier to sell or rent
04
Sealing the roof in time avoids costly emergency repairs to ceilings, finishes and furniture later
05
Water repellents and technical coatings keep façades looking right, preventing saltpetre stains and flaking
06
Certified materials, expert supervision and a 5-year warranty on every waterproofing project
Igor Priazhnikov, founder of “Obra É Fácil”
People only think about waterproofing once the damage is already done, a stain on the ceiling, damp in the basement, mould that keeps coming back. I’d rather catch it before that. Done right, it protects the whole building for years, and that’s what I stand behind on every job we take.
How We Plan Your Waterproofing
DIAGNOSIS, QUOTE AND EXECUTION WITH A 5-YEAR WARRANTY
Waterproofing done right starts by finding where the water actually comes from, not just where it shows. At Obra É Fácil, we begin every project in Lisbon, Setúbal and Coimbra with a free, detailed assessment of each roof, terrace or basement, then explain the solution we’d use and why. You know exactly what will be done and what it protects before any work begins. Here is how the process runs.

Consequently, those seeking professional waterproofing costs in Lisbon, Setúbal, or Coimbra receive accurate estimates and the security of a proven methodology. Every stage includes expert technical supervision and detailed photo reports, allowing the client to personally verify the creation of a reliable protective barrier against moisture and the destructive effects of time.
The cost of waterproofing in Lisbon, Setúbal or Coimbra depends on a few things: the total area, the condition of the base surface, and the system the job needs. At Obra É Fácil, every quote is detailed, so you know exactly what it costs to waterproof a terrace or roof, with a clear price and no hidden extras.
Waterproofing a roof, basement or pool needs a proper diagnosis first, to find the real source of the problem, not just the visible damage. Prices vary with the complexity of the expansion joints and weak points, but the goal is always the same: a lasting seal that saves you from costly repairs later and protects the value of your property.
Watertightness projects for roofs, basements, or pools require precise technical diagnostics to eliminate chronic structural pathologies. While waterproofing prices vary depending on the complexity of expansion joints and critical points, we focus on delivering high-performance systems that prevent costly future maintenance and guarantee the long-term appreciation of your property assets.
Once your walls and ceilings are properly sealed, complete your renovation with our Painting services.
Frequently Asked Questions
WATERPROOFING AND MOISTURE PROTECTION WITHOUT SECRETS
What is the best waterproofing system for the Portuguese climate?
Is it possible to waterproof basements or garages in existing homes?
Yes. We operate in occupied buildings using interior waterproofing techniques, such as resin injections or high-adhesion cementitious coatings. This approach seals water entry from capillary action or negative pressure without the need for complex external excavation, quickly restoring the space's health and usability.
Do you perform isolated waterproofing for just one terrace or roof?
Yes. We execute specific projects for rooftops, focusing on the meticulous treatment of critical points such as expansion joints, drains, and chimneys. A targeted and well-executed intervention in these areas is often sufficient to resolve severe leaks affecting lower-floor ceilings, ensuring total structural protection.
Does waterproofing permanently solve the appearance of mold and fungi?
Yes, provided the cause is external infiltration or moisture rising through foundations. By blocking water entry into the masonry, we eliminate the nutrient source for microorganisms. For perfect results, we often recommend combining this with thermal insulation solutions to prevent internal condensation as well.
Is there a cost for a technical diagnosis and estimate?
No. At Obra É Fácil, we always provide a professional airtightness diagnosis and a detailed quote free of charge. Our goal is for the client to understand their property’s technical pathology and the proposed solution before making any investment, ensuring total transparency.
What durability warranties are provided for your services?
All our waterproofing projects include a 5-year technical warranty from Obra É Fácil. We exclusively use certified materials from market-leading manufacturers, ensuring your "invisible shield" against water maintains the performance and elasticity needed to follow the building's natural movements.
