Do I Need a Soil Test If My House Is Already Built?
Short Answer: Yes, in certain situations.
Many property owners search this question when
they're planning to renovate, add another floor, or
buy an existing property.
The good news is that a soil investigation isn't only
for vacant lots. Depending on your project, it may
still provide valuable information for engineers.
You may need a soil investigation if:
1. You're adding another floor.
2. You're planning a major extension.
3. You're replacing an old building.
4. You're seeing signs of settlement.
If you notice cracks, uneven floors, or doors and
windows that no longer close properly.
Can a Soil Test Be Done After Construction?
Yes.
Experienced geotechnical teams can perform soil
investigations on developed properties by selecting
appropriate drilling locations while considering the
existing structure and site conditions.
