who are we

One-stop technical support provided by investigation, reporting, evaluation and maintenance

We are a professional engineering consulting company established in Hong Kong, focusing on water seepage detection, leakage source analysis, loss assessment, maintenance plan recommendations, expert technical support services and waterproofing works. Based on scientific testing, objective analysis, professional judgment and practical experience, the company is committed to finding the cause of leakage accurately for customers, evaluating the degree of impact, and providing practical solutions to help all parties solve problems more effectively.

The problem of water seepage in buildings is often complicated, which may involve aging failure of the waterproofing layer, cracks in the outer wall, leakage of window frame, and drainage of water supply and drainage. Leakage of pipes, water seepage on the bathroom and kitchen platform, damage to the platform or roof waterproof layer, and even hidden in the interior of the building structure. Therefore, we attach importance to the comprehensive analysis of various professional instruments, testing technology and inter-professional teams to provide customers with scientific basis, objective and reliable investigation and consulting services.

Dayu’s professional team has assisted the Hong Kong government in dealing with a large number of water seepage cases in the past, and has rich practical experience in technical analysis, responsibility determination and disputes related to different institutions and customers.

our philosophy

Investigate and judge by objective analysis by scientific method

We believe that the key to the effective handling of building leakage and related losses lies in accurate investigation, objective analysis and appropriate solutions. Only on the basis of fully grasping the facts, data and technical rationale can we avoid misjudgment, reduce disputes, and assist all parties in making correct decisions.

Types of customers we serve

technical ability

Dealing with complex leakage problems with professional technology

We use a variety of advanced detection technologies and professional instruments to test, record and analyze different types of leakage problems, including infrared thermal imaging detection, microwave faults Scanning detection, conductive induction humidity detection, electronic pressure gauge inspection, traditional color water testing, penetrating radar testing, water sample analysis and color dye analysis laboratory tests.

Identify potential water seepage range, moisture accumulation position and abnormal distribution using temperature difference changes, and provide important technical reference for leakage investigation.

It is suitable for detecting the humidity distribution and abnormal conditions inside the wall, floor and building components, and helps to analyze the hidden leakage and water diffusion path.

Measure the changes of the surface and shallow humidity of building materials to evaluate the moisture range, humidity distribution and water seepage trend, as an important basis for on-site investigation.

Through the radar, the position of the steel bars and throat pipes in the building structure is detected, and the water sample analysis is used to determine the source of water, which provides a more comprehensive scientific basis for the research and judgment of the source of leakage.
