Even if the land is flat, it doesn't mean the supporting layer is flat! Infer the geological composition and conduct accurate and economical ground investigations!

The ER Ground School is a ground course aimed at small-scale buildings, delivered in collaboration between a ground consultant (representative of Blue Sage Co., Ltd.) and Earth Relations. In the special edition, we provide a clear explanation of "Foundation Planning to Prevent Building Tilt" through a PowerPoint video. The depth at which the supporting layer appears is not constant, and even if the land is flat, the supporting layer is not necessarily flat. For more details, please refer to the related links. [Key Points] 1. Why do buildings tilt? 2. Driving piles 3. Ground investigation plans to increase asset value *For more information, please check the related links page or feel free to 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.
