There are two methods for waterproofing repairs: the "removal method," which involves removing the existing waterproofing, and the "overlay method," which forms a new waterproof layer on top of the existing one. Additionally, the replacement work for sealing on exterior walls is carried out using one of three methods depending on the situation: "scaffold installation," "temporary gondola," or "rope work."

If the airflow under the floor is poor, moisture tends to accumulate, leading to mold growth and wood decay, creating a favorable environment for termites. Once wood has rotted, it cannot be restored to its original state. The area under the floor is crucial for supporting the home; if the foundation or pillars lose their original strength, it can be a serious issue. Why not take a moment to investigate the often-overlooked space beneath your floor? 【Types of Measures】 ■ For damp, humid areas under the floor: Moisture-proof charcoal ■ For concrete floors with poor ventilation: Underfloor ventilation fan ■ For areas under the floor where moisture and termites are a concern: Anti-termite and moisture-proof sheets *For more details, please refer to the PDF materials or feel free to contact us.

"Building exterior wall inspection" is an essential management item for building owners. Through the echoes from tapping with a probe, it is possible to determine the detachment of exterior wall tiles and mortar in a "tapping survey," and by using infrared thermography, the temperature differences on the surface of the exterior wall can identify detachment in an "infrared survey." We conduct inspections using safe and reliable techniques. 【Flow of Exterior Wall Inspection】 ■1. Consultation for exterior wall inspection ■2. Submission of estimate ■3. Conducting the inspection ■4. Reporting the inspection results ■5.

"Large-scale renovation work" protects important assets. All buildings, including condominiums, rental apartments, office buildings, factories, and stores, deteriorate over time, and if left unattended, this can shorten the building's useful life. Implementing renovation work at the appropriate time in a planned manner is a way to maintain the economic value of building assets. It is economically beneficial to complete any work that requires scaffolding during this opportunity.
