Zerco Infrastructure S.R.L.
Roads, bridges, and the quiet work that keeps cities moving.
We plan and build civilian engineering works — asphalt corridors, drainage systems, and the concrete details most people only notice when they fail.
See what we buildAbout the company
Based in Romania, Zerco Infrastructure S.R.L. supports public and private clients with surveying, earthworks, pavement design, and site supervision. Our crews treat alignment, compaction, and drainage as one continuous system — because a smooth surface means little if water has nowhere to go.
From rural access roads to urban rehabilitations, we favour durable materials, clear documentation, and schedules that survive wet seasons and utility surprises.
Civil works we handle
- Road construction & rehabilitation — sub-base, binder, and wearing courses for local and county roads.
- Drainage & culverts — ditches, storm inlets, and pipe crossings sized for peak rainfall, not average weather.
- Sidewalks & intersections — curb returns, tactile paving, and sight-line improvements for safer crossings.
- Earthworks & grading — cut-and-fill balancing, embankment stability, and site preparation for new corridors.
Field notes from the road
A well-compacted subgrade can carry traffic loads for decades; a poorly drained one can fail in a single freeze–thaw cycle. That is why Zerco crews spend as much time watching moisture content as they do watching the paver.
- Hot-mix asphalt is typically laid between 140°C and 160°C so the mat densifies before it cools.
- A 2% cross-slope is often enough to move rainwater off a carriageway without making steering uncomfortable.
- Flexible pavements spread wheel loads through layered stone and bitumen; rigid pavements rely on concrete slab strength and joint design.
- Most premature pavement cracks start below the surface — in weak soil, trapped water, or an uneven foundation layer.
- Guardrails, markings, and clear sight distances are part of the engineering package, not optional finishing touches.
