Basic flow of ground guarantee system
Research
The risk of uneven settlement cannot be determined simply by numeric data obtained through ground investigation. The House Warranty entrusts an investigation from various aspects to an affiliate company, taking into consideration the numeric values and the locational conditions, surrounding environment and soil quality.
Balancing “low cost” and “high level of safety”
By completing a ground investigation at a high cost, you may be able to deeply explore the possibility of uneven settlement. However, such a cost is too large for an ordinary housing. Therefore, House Warranty employs a simplified and low cost ground investigation method.
Be advised that this is just a simplified ground investigation method and it is not possible to completely eliminate the possibility of ground accident. To cover the remaining uncertainty, we offer a guarantee.
Based on the long-accumulated expertise as an expert in ground guarantee as well as highly accurate analyses backed up by experiences with past cases, we will reduce the number of ground accidents as much as possible to zero.
Analysis / proposal
By comprehensively analyzing all investigation data, we will propose foundation specifications that are most appropriate for the building and the ground. Work to produce the foundation specifications according to the proposal servers as the precondition for ground guarantees.
“A third party” judges the necessity for improvement work
By separating the company that conducts the investigation and the company that completes the improvement work and thus analyzing and judging the investigation data from a third party’s point of view, we objectively determine the necessity in a grey zone where it is uncertain whether improvement work is really required. In this manner, the number of housings that can secure the safety without conducting improvement work will drastically increase.
Countermeasures
If the risk of uneven settlement is recognized because of soft ground or similar factors as a result of analysis, we will conduct reinforcement work of the foundation or ground improvement work. Even in this case, we will offer an appropriate work so as to avoid excessive quality.
