With over 20 years of experience and a highly skilled team, we pursue innovative technological solutions to deliver services quickly, efficiently, safely, and with quality that exceeds our clients’ expectations — always respecting the environment and the surrounding communities. Operating throughout Brazil, we serve in the areas of waterproofing, structural repair, and reinforcement. We have supported various industries, concessionaires, petrochemical companies, energy providers, and sanitation companies — driving their business growth in a safe and sustainable way.
Used to address pathological issues related to waterproofing and/or the restoration of the monolithic nature of a structural element, as well as to treat cracks, resin injection plays a key role in structural rehabilitation.
The plugging process consists of filling galleries with a project-specified material of appropriate strength. This increases the stability and resistance of the gallery — and, consequently, of the dam — ensuring the watertightness of the system.
Technical assessment of structures and identification of pathological manifestations, tracing their causes and origins, and defining the most appropriate repair methodology. Each client has a specific context, so we assess the condition of the entire element — from visible coatings to the internal structure — using advanced testing and technology.
We take a critical and customized approach, proposing a set of solutions based on structural demands and defining the appropriate type of reinforcement for optimal performance. Reinforcement is always designed according to the requirements of technical standards such as NBR 6118 (concrete), NBR 8800 (structural steel), and international references when there is no national regulation (e.g., carbon fiber reinforcement).
Waterproofing is the process of protecting structures against the passage of fluids (water or gases), ensuring healthier environments, safety, and user comfort. It guarantees the watertightness of the construction elements that require it. Several waterproofing systems are available, adapted to each need. - Crystalline waterproofing - Polymer-modified mortars - Polyurethane-based resin application - Polyurea - PVC membrane
Hydrodemolition offers several advantages in construction and renovation projects. This method uses high-pressure water jets to remove concrete or other materials with high precision, minimizing the impact on adjacent structures. It is safer for workers, reduces dust and noise, and promotes a cleaner work environment. Additionally, it preserves the substrate better and allows for more controlled and effective removal, making hydrodemolition an efficient and sustainable choice in various engineering applications.
