Master foundation stability with Dynapac CA-Series soil compactors. Engineered for deep-layer compaction and maximum traction, our single-drum vibratory rollers ensure the required load-bearing capacity for highways, dams, and mining infrastructures.
Soil Compactors
The Dynapac CA Fleet series
The Dynapac CA series is the industry standard for soil stabilization. From the versatile CA25D to the ultra-heavy CA70D, our fleet delivers superior amplitude and frequency control to achieve target density in fewer passes.

Expert Insights: Achieving Maximum Soil Density
Compaction efficiency depends on matching the machine's static linear load and vibration frequency to the soil type. We provide the analytics to ensure your foundation meets international safety and durability standards.
SEISMIC automatically detects the soil's natural frequency and adjusts the drum's vibration accordingly. This reduces fuel consumption by up to 25% and prevents soil "bouncing" or over-compaction.
For massive rockfill or deep soil layers, the CA65D and CA70D are preferred due to their high static linear load and extreme centrifugal force.
Dynapac compactors provide real-time stiffness data (CMV) to the operator, indicating exactly when the target compaction is reached, avoiding unnecessary passes.
Yes. They feature high-capacity cooling systems and cross-mounted engines for easy maintenance and 24/7 reliability in high-temperature environments.

Soil Compactors for Africa’s Foundation Projects
SMT provides specialized compaction solutions to meet the structural requirements of major infrastructure and industrial developments across the continent.
Secure productive mining routes and tailings facilities with rollers built for continuous, high-stress earthmoving in 24/7 environments.
Mining Infrastructure
Achieve the extreme density standards required for rockfill dams and reservoirs with our heavy-duty CA-series vibratory compactors.
Dams & Water Management
Build durable transport networks. Our rollers ensure the load-bearing capacity needed for high-speed highways and heavy freight rail corridors.
Civil Engineering
Integrated Site Preparation Workflows
Efficiency on-site is driven by machine coordination. We synchronize our compaction fleet with grading and excavation units to ensure seamless project progress.
Bulldozer & Roller Synergy
Pair our [Bulldozers] with CA rollers to instantly stabilize every layer of soil as it is graded, preventing erosion and site delays.
Excavator & Compactor Duo
Match your soil rollers with our [Excavators] to ensure rapid, high-density compaction of backfilled trenches and foundation pads.
Specialized Padfoot (PD) Configurations
For cohesive soils like clay and silt, standard smooth drums are insufficient. SMT provides specialized Padfoot options to ensure deep penetration and perfect compaction in difficult soil conditions.
-
Cohesive Soil Mastery
The padfoot (PD) drum "kneads" the soil, breaking up lumps and forcing air out of cohesive materials for a solid, uniform foundation.
-
Padfoot Shell Kits
Many of our models (CA25 to CA65) can be fitted with a Padfoot Shell Kit, allowing you to switch from smooth to padfoot drum depending on your project needs.
-
Enhanced Traction in Mud
The padfoot design provides additional grip in wet or slippery conditions, ensuring the compactor maintains movement on challenging earthwork sites.
