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.
Technical Waterproofing Solutions
TOTAL WATERTIGHTNESS AND STRUCTURAL PROTECTION
Protection against water ingress is the cornerstone of any building’s longevity. At Obra É Fácil, waterproofing systems are implemented with engineering rigor, utilizing high-performance membranes that eliminate humidity-related pathologies. The focus lies on creating impenetrable barriers for terraces, roofs, and foundations, ensuring indoor air quality and a real increase in property value.
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
Professional waterproofing prevents reinforcement corrosion and concrete degradation, ensuring the foundation and structure remain intact for decades.
02
Creating watertight barriers eliminates excessive capillary moisture and condensation, ensuring healthy indoor environments free of harmful mold and fungi.
03
A fully watertight building with protected facades attracts a higher market value, facilitating sale or rental through a mark of construction quality.
04
Preventive measures in rooftop sealing avoid costly emergency repairs caused by structural damage to ceilings, finishes, and interior furniture.
05
The application of water repellents and technical coatings preserves the original appearance of exterior finishes, preventing saltpetre stains and premature material detachment.
06
We exclusively use certified materials under specialized supervision, ensuring that every waterproofing project benefits from an absolute and long-lasting performance warranty.

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.
