Ground Investigation "SDS Test"

Screw driver sounding test to support accurate ground evaluation.

Our company conducts the "SDS Test," a testing method to more accurately assess soil quality and support precise ground evaluation. In the conventional SWS test, soil types (loam, sandy soil, clay, humus, fill) were estimated based on sounds like "gritty." However, this new test enhances the accuracy of soil estimation by referencing parameters such as torque, terrain conditions, and nearby boring data. 【Overview】 ■ Number of measurement items: 3 components ■ Measurement items - Load: Wsw - Rotational torque: T - Settlement per rotation: δ ■ Number of measurement points every 25 cm: 1 to 7 points *For more details, please download the PDF or contact us.

[Knowledge of Ground] About Differential Settlement

Many of the causes of building tilting are related to the ground! We will introduce examples of differential settlement caused by the ground with illustrations.

This column presents examples of differential settlement caused by ground conditions, illustrated with diagrams. The purpose of ground investigation and ground reinforcement work is to prevent differential settlement (tilting of the house) in residential buildings. This is to avoid situations like "after a few years of living here, marbles started rolling on the floor..." For more details, please refer to the related links. We encourage you to read it. [Contents (partial)] ■ Uniform settlement and differential settlement ■ Examples of causes of differential settlement - Cases caused by the contraction of weak strata - Cases related to retaining walls and backfill - Cases caused by embankments - Cases due to poor design and construction of ground reinforcement *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

[ER Ground School] Session 1: Understanding Ground Conditions for Residential Land to Prevent House Tilting

Features of the ground company and ground insurance/guarantee company you want to choose! The important thing is to compare each item!

The ER Ground School is a ground course for small-scale buildings, delivered in collaboration with a ground consultant (representative of Blue Sage Co., Ltd.) and Earth Relations. The first session will clearly explain "The Concept of Residential Ground that Prevents House Tilting" through a PowerPoint video. "We see numerous ground accidents occurring every year, yet there are companies that have almost never caused an accident." "If you want to choose a company that does not cause accidents, focus on 'number of accidents' and 'accident rate.'" [Key Points of the Discussion] 1. The reason I want to convey this again = because ground accidents are not decreasing. 2. The concept of residential ground that prevents house tilting. 3. What considerations are being made to prevent accidents. *For more details, please refer to the related link page or feel free to contact us.
