Dėdeliškės Petrol Station in Lithuania

Settlement of the asphalt surface at an operating petrol station was corrected using deep geopolymer injection. The height difference was eliminated within 5 hours, with no interruption to station operations.

Object: Dėdeliškės Petrol Station
Location: Dėdeliškės, Lithuania
Sector: Fuel Stations / Infrastructure
Technology: Deep geopolymer injection
Project: Levelling asphalt–concrete height difference; subsoil stabilisation
Product used: GEO LIFT R055
Injection depth: 1.6 m (below geogrid layer)
Duration: 5 hours
Owner: Circle K
Contractor: Geolift Baltic UAB
Engineer: Valdas Kordusas

Problem

The asphalt surface settled by approximately 50 mm, creating a hazardous height difference with the adjacent concrete slab.

Cause

The petrol station was constructed on land previously occupied by a marshy lake. Underlying sapropel and peat layers, covered with fill soil, gradually compressed and shifted under traffic loads.

Risk

Tire and vehicle damage
Safety hazards for customers
Progressive settlement if left unaddressed
Potential operational disruption

Solution

Targeted geopolymer injections were performed beneath the affected asphalt area to:

Stabilise weak subsoil layers
Restore load-bearing capacity
Lift and re-level the asphalt surface
The injection depth reached 1.6 m below the geogrid layer.

Only the immediate working zone was closed; the station remained operational.

Execution & Results

Asphalt surface re-levelled (≈50 mm)
Works completed in 5 hours
Only local area temporarily closed
No excavation or demolition required
Station operation uninterrupted

Benefits for the Client

No downtime for the petrol station
Fast and efficient execution
At least 2× more cost-effective than traditional repair methods
Long-term ground stability in complex soil conditions
