Compactor vs rammer: Which is best for your needs
All contractors and builders will need to compact soil and substrate during their projects. Three important tools to achieve this are a roller compactor, plate compactor and tamping rammer. While all three are excellent at compacting substrates, their ideal applications are different.
Cutting Edge is Zimbabwe’s supplier of Husqvarna construction machinery. We have roller compactors, plate compactors and tamping rammers available for local contractors. But how can you decide which of these machines is best for your upcoming building project? First, you need to understand soil compaction.
Soil compaction: The basis for a robust project
In any construction project, compaction of the soil is an essential stage. The process entails compacting loose substrate particles in order to eradicate air spaces and establish a firm, sturdy base. Effective compaction guarantees stability; compacted soil gives buildings a solid foundation, reducing settling and the risk of foundation failure.
It also leads to improved load-bearing capacity as denser substrates are able to carry larger loads without giving way. Compacted soil is less vulnerable to water and wind erosion and is more effective at water drainage.
Rammer, roller compactor and plate compactor
Cutting Edge provides a wide selection of Husqvarna compaction equipment to meet different project needs. The three primary types and their functions are broken down as follows:
1. Plate compactors – These machines compact soil layers by vibrating a flat plate at a high frequency. They are perfect for crushing and compacting granular materials like crushed rock, gravel, and sand. A plate compactor should be used on the base layers for pavements, driveways, patios, and trench backfill. They are a popular option for various landscaping and building tasks because of their adaptability.
Plate compactors are available in reversing and forward variants, providing flexibility in confined areas. Different plate sizes meet the demands of various projects. Compaction depth can also be controlled with an adjustable compaction force.
2. Tamping rammers (jumping jacks) – These small machines compact dirt in tight spaces by delivering strong, focused blows to the earth. They are ideal for silty and clay-based cohesive soils. Rammers work well in regions where larger equipment cannot reach, such as trenches, foundations, the spaces around posts and poles.
They can achieve deep compaction due to their high impact force. Tamping rammers are portable and lightweight, which makes them perfect for navigating confined construction sites. On the right substrate, the higher impact force of tamping rammers guarantees deeper compaction than plate compactors.
3. Roller compactors – These large machines are another essential tool for large-scale soil compaction projects. They drive on two metal drums and rely on their weight and vibration to compact the substrate. A roller compactor can either be ridden or walked behind, but it is commonly used for larger projects where a wider area needs to be compacted, such as roads, embankments and warehouse floors.
Choosing between these compaction machines
Plate compactors are the most appropriate for granular materials such as crushed rock, gravel, and sand. Tamping rammers are perfect for silty and clayey cohesive soils due to their high impact force. Roller compactors are the best solution for larger projects where a wide surface area needs to be prepared. The following table outlines each machine’s compaction depth on various substrates:
Sand/gravel | Clay | Silt | Base | |
Plate compactor | 30cm | 20cm | 20cm | 20cm |
Tamping rammer | 40cm | 35cm | 30cm | 30cm |
Roller compactor | 15cm | 20cm | N/A | 15cm |
*These stats are based on the Husqvarna compaction machines we have in stock.
Other considerations for choosing your compaction equipment include the following:
- Machine weight – Take into account the equipment’s weight in proportion to the kind of soil and the required compaction depth. In cohesive soils, lighter rammers could be more appropriate if deeper compaction isn’t the main issue.
- Quality and brand – Purchasing top-notch tools from a recognised company like Husqvarna guarantees dependability, longevity, and peak performance for your job.
