Earthworks in Saudi Arabia – Excavation, Backfilling, Leveling, Dewatering & Testing by DTC (Dorar Tammam Company)

Earthworks are the foundation of every successful construction project. Before concrete is poured, structures erected, or MEP systems installed, proper site preparation and earthwork execution must be completed with precision and expertise.

In Saudi Arabia’s rapidly growing construction sector, the demand for professional earthwork contractors has significantly increased—especially for projects in Dammam, Khobar, Riyadh, and across the Kingdom.

At DTC (Dorar Tammam Company), we provide comprehensive earthwork services including excavation, backfilling, leveling, dewatering, and soil testing, ensuring that every project starts on solid ground.

Road and infrastructure excavation

Key Considerations:

Soil type
Depth and slope stability
Safety measures
Shoring and support systems

2. Backfilling Works

Backfilling involves replacing soil after excavation to support structures and underground utilities.

Materials Used:

Selected fill material
Sand fill
Crushed aggregate

Important Steps:

Layered filling
Compaction control
Moisture conditioning

Proper backfilling ensures:

Structural stability
Prevention of settlement
Long-term durability

3. Leveling & Grading

Leveling ensures the site is prepared according to design elevations.

Includes:

Rough grading
Fine grading
Site leveling using advanced equipment

Benefits:

Proper drainage
Accurate foundation levels

4. Dewatering Works

Dewatering is essential when groundwater interferes with excavation.

Methods Used:

Wellpoint systems
Deep well systems
Sump pumping

Importance:

Keeps excavation dry
Prevents soil collapse
Ensures safe working conditions

5. Soil Testing & Compaction Testing

Testing ensures the soil meets engineering standards.

Types of Tests:

Soil classification tests
Compaction tests (Proctor test)
Field density test (FDT)
Plate load test

Why Testing Matters:

Ensures load-bearing capacity
Prevents structural failure
Confirms compliance with specifications
