For residential use: Non-destructive testing that measures in "areas" rather than "points," without damaging the ground! Reducing unnecessary ground improvement and piling work to cut costs!
The "Surface Wave Exploration Method" involves applying vibrations to the ground using a vibrator, and receiving those vibrations with two detectors to measure the speed of the vibrations traveling between the detectors. Since it allows for an understanding of the surface ground strength, it reduces unnecessary ground improvement and pile construction judgments compared to other survey methods, thereby decreasing costs. By reducing pile construction, which is treated as underground buried objects, it is more environmentally friendly and lessens the decrease in land real estate value. 【Features】 ■ Measurements are taken at five locations on the site (four corners and the center) → This allows for a comprehensive assessment of the ground conditions and predictions of subsurface layer inclinations. ■ Accurate values that do not rely on human intuition. ■ Measurement is done over an area rather than a point. → The range between detectors (usually a circular area of 1 meter). → It is possible to obtain average ground information rather than partial information due to gravel or foreign objects. ▼ Seminar video now available!

basic information
**Comparison with Existing Survey Methods** ~Surface Wave Exploration Method~ → By shaking the ground and measuring the speed of the "vibration," the hardness or softness of the ground is determined. → The boundaries of strata are identified from changes in data, allowing for an assessment of the bearing capacity of each layer. ~Existing Survey Method: Swedish Sounding Test (SS Test)~ → A rod with a screw tip is rotated and driven into the ground at intervals of 25 cm. The rotation speed is used to determine the hardness or softness of the ground. → The bearing capacity of the ground can be assessed at every 25 cm interval. **Significant Cost Reduction** ○ If the ground can support the structure, no improvement work is necessary. ○ Although the cost of surface wave exploration is higher than that of the SS test, it allows for a more detailed and gradual assessment of the ground, eliminating unnecessary ground improvement work. ○ This leads to a significant reduction in total costs (ground survey + construction costs).
