Building Renovation Technology: Waterproofing Work

We respond quickly to a variety of water leakage situations

For buildings and structures, leaks are a major cause of deterioration and loss of durability. Moreover, the measures to be taken to prevent water leakage will vary depending on the location and cause of the leakage, so solid knowledge is necessary.

If appropriate measures are not taken, “water leaks again after repair” may occur. We will use our reliable investigation techniques to identify the cause of the problem and propose the most appropriate waterproofing method according to the situation at the site.

Water stop

Stop water leakage to leakage points in the building, etc.

Waterproofing is performed at the time of construction, while waterproofing is performed for water leakage after construction is completed. Especially common are the space areas of underground structures such as warehouses embedded in underground portions.
Because of the strong pressure from underground, if there are cold joints or cracks, even if they are only small cracks, water pressure will be concentrated there and water will enter. Stopping this requires a high level of skill and experience.

Underground water sealing

- WATER STOPPING -

As for waterstoping work, the same objective is to stop leaking water as in ordinary waterproofing work, but there is a big difference in the techniques and methods required for this.

Especially when performing water sealing work on underground structures, it is necessary to make repairs to cope with the water pressure that is constantly applied. For this reason, the required investigation techniques and knowledge must be of a higher level than those required for normal rooftop waterproofing or exterior wall leaks.
