A 20-ton tamper drops from 25 meters onto the ground. On a site near the Colorado River, we watch the impact crater form and the surrounding soil settle. That is dynamic compaction design in Austin at work. The process improves loose fills and collapsible soils common in areas like Mueller and the East Side. Our team coordinates the drop pattern, grid spacing, and energy per point based on the target depth. Before we start, we always review the subgrade conditions with a plate load test to confirm the bearing capacity we can expect after treatment. The equipment we use is heavy and precise.
The tamper energy reaches 300 tm per drop, and we apply multiple passes until the target density is verified in the field.
