The Applications of a Tamping Rammer

On a construction site, soil compaction is one of the most common processes that needs to be carried out to get a job done safely and effectively. Drainage is one of the early stages of any construction site ensure a long-term, solid and stable site – tamping rammers are the essential tool for compacting soil in drains and around pipes.
But what kind of soil are tamping rammers suited for? What’s the average tamping rammer price? And how powerful does a tamping rammer need to be to function effectively?
The team at MEIWA have done the research so you don't have to. In this blog, we delve into the nitty gritty world of soil compaction, and share everything you need to know before you go and spend your hard-earned money on a tamping rammer.

Why Use a Tamping Rammer?

Every type of soil behaves differently depending on what elements it is composed of, and therefore requires different methods of compaction.
The desired level of compaction is best achieved by matching the soil type with its suited compaction methods. Cohesive soils, as in those that are made up from particles that stick together, i.e clay, require a tamping rammer, delivering a direct impact with a high impact force. This is to ensure that the soil particles are moved effectively, forcing the air and water trapped between then out – ultimately creating a solid, stable ground surface to work with.

However, is you are working with Granular soils, i e sand, a vibrating plate is often a more effective form of compaction. Call us to discuss.

Characteristics of a Rammer

There are two factors that are essential in determining the type of force a tamping rammer requires: frequency and amplitude.

Frequency pertains to the speed at which the machine jumps and the eccentric shaft rotates and is usually given in terms of vibrations (or impacts) per minute (vpm). Amplitude on the other hand is the magnitude of vibration, which is affected by weight, power and centre of balance. These two factors together influence the “Impact Force”. Only the experienced manufacturers (like MEIWA) get the balance right between travel speed, compaction depth and smooth operation.

Tamping rammers, also known as trench rammers or trench tampers, deliver high impact force which make them the ultimate choice for soils that are cohesive and semi-cohesive, like clay or silt. Rammers cover three types of compaction: impact, vibration, and kneading, and are usually powered by gasoline or diesel which can offer a frequency range of anywhere between 500-750 blows per minute.

Why Choose MEIWA?
