Question 1

What is the Vibro Replacement (stone column) method?

Accepted Answer

Vibro replacement uses a vibrating probe to create a column-shaped cavity in soft soil, which is then backfilled with crushed stone compacted in lifts. The resulting stone columns increase load-bearing capacity and accelerate drainage consolidation — making them ideal for soft clay and silty soils.

Question 2

When is dynamic compaction used instead of stone columns?

Accepted Answer

Dynamic compaction uses a heavy drop weight to densify loose granular soils and fill materials. It is most effective in granular soils with minimal fines, while stone columns are preferred in cohesive/clay soils. Parkline assesses site-specific soil conditions and recommends the optimal method.

Question 3

How long does a ground improvement programme take?

Accepted Answer

Timelines depend on soil type, area extent, and chosen technique. A stone column programme for a 5,000 m² industrial site typically takes 4–8 weeks. Preloading with surcharge can take 3–6 months to achieve the required consolidation. We provide detailed execution schedules at tendering stage.

Question 4

Does ground improvement eliminate the need for deep piles?

Accepted Answer

In many cases, yes — ground improvement can replace deep pile foundations, significantly reducing cost. However, the right solution depends on load magnitude, allowable settlement, and soil conditions. Our geotechnical team assesses each project to recommend the most cost-effective approach.

Question 5

Which clients has Parkline Infra delivered ground improvement work for?

Accepted Answer
