Why Compaction is Important

 

As many homeowners look for ways to improve the appearance and value of their property, driveways, patios and retaining walls are becoming increasingly popular.

If you want a good quality and long-lasting finish, proper excavation (8 to 12 inches in depth, depending on the purpose of the finished project) and compaction are essential, but they are often steps which are overlooked.

Using proper compaction techniques throughout the project is a relatively easy way to produce a finished product that will not only increase property value but save property owners time and money on future repairs.

Inadequate excavation and compaction can lead to uneven and unstable surfaces which can be unattractive and hazardous. It can often require repair and replacement sooner and more frequently than projects installed using proper compaction techniques which can make it more costly in the long term.

For example, take a driveway constructed with interlocking blocks. Without proper compaction, both the base and blocks lack stability. The weight of vehicles on the driveway will cause the materials to shift and compress which will eventually result in grooves or ruts.

Failing to properly compact the surface may also result in air voids under the structure, and between the blocks, where water can collect. If the temperature drops below zero the water will freeze and expand, causing the blocks to lift, resulting in an unattractive, hazardous and uneven surface.

Once the ground has been excavated we recommend going over the surface three or four times with the compactor to ensure that the sub-base is being placed on an even and solid surface.

The sub-base material (usually limestone or sandstone) should be added in 4- to 8-inch lifts, with compaction occurring after addition. Bear in mind that the thickness of the lift affects compaction.

Compaction can also be affected by moisture content. Adding moisture with a garden hose or a compactor’s on-board water tank allows the sub-base particles to create a paste and bond together, forming a much stronger finished product. However, it is important to not saturate the sub-base material. To test moisture, pick-up a handful of sub-base and squeeze it. Properly moistened material will hold together in a solid clump.

Following the addition and proper compaction of the sub-base layer, we recommend a 1-inch layer of sand bedding to be placed over the entire surface area. This will connect the blocks to the sub-base and allow a softer surface into which the blocks can settle.

After the blocks are placed in the desired pattern, the surface should be compacted using a protective rubber mat to prevent damage to the surface of the blocks (which come as standard with all our compactors) to protect the blocks. Two to three passes should suffice.

Once the initial compaction of the blocks has occurred, an additional two to three passes should be made over the blocks as fine sand is swept into the joints. This final compaction will settle the blocks into the sand and create density between the blocks.

The Right Equipment

One of the best ways to ensure proper compaction is to select the proper equipment for the project. Most landscape projects require the use of a  single or multi-directions vibratory plate. One exception is the compaction of cohesive, or clay based, soils. As they require impact, as opposed to vibration, to compact at the correct density which is better achieved by a Tamping Rammer.

For most interlocking block paver jobs a vibratory plate with a compaction force between 13 and 22KN should be sufficient.  In addition to the compaction force, the vibrations per minute should also be considered when selecting a plate compactor. A higher frequency is often more suitable for the small aggregates used in interlocking-paver projects.

A fully-protected, high-horsepower engine and a solid base plate are also important features to look for when selecting plate compactors. All our compactors include a rubber paving mat, removable handles and a wheel kit for ease of transportation. We also offer a range of compactors with inbuilt and removable water tanks which make adding moisture to the soil easy and convenient, even in areas where water is hard to obtain and are perfect for block paving and tarmacking.

Our Guide to Buying the Perfect Wacker Plate

Firstly, we would like to clarify that when we talk about Wacker Plates, Wackers, Plate Compactors or Vibratory Plates we are talking about a machine that is used to compress soil and/or gravel which is most commonly called a Compactor Plate. As with the terms hover and vacuum cleaner these names have become interchangeable and we will refer to them all throughout our guide.

If you are looking for a Wacker Neuson branded machine then I’m afraid that you have come to the wrong site. What we have on offer are better value equivalents!

Our current selection of Wacker Plates range from 60 up to 300 kg. Whether you are after a Petrol, Diesel, single direction, forward/reverse or one with a built-in water system we are sure to have a Wacker to suit your requirements shop now.

If you are after something economical, or if you are working on a site with only a Diesel fuel supply, then one of our Diesel Compactors could be the perfect choice for you. Although a Diesel is likely to half the cost of fuel and save you having multiple fuel supplies on site, you need to bear in mind the higher initial purchase cost and service costs which would mean you would have to carry out much more work to justify the expense.

In addition, Diesels have a poorer power to weight ratio meaning that you need a heavier machine, than an equivalent petrol, to complete the task. If you compare our Lumag RPi15D Diesel Compactor to our Lumag RP1100PRO Wacker, which is the nearest Petrol equivalent, you will see that both offer the same travel speed and compaction speeds but the Lumag RPi15D Diesel is 35 kg heavier than the Lumag RP1100PRO which weighs in at 95 kg and costs £380.00 more.

If you are looking for a Compactor that is easy to manoeuvre, yet still packs a good punch, our range of dual direction forward/reverse Compactors will be the ones for you. The reversibility drastically improves the operators control of the machine. The operator can work the machine up to a wall or along a trench without having to drag the machine backwards avoiding undoing the good work that it has done and saving considerable time and effort. This comes in particularly useful when using some of the heavier Wacker Plates, which may be too heavy for a single operator to drag backwards.

Our reversible Wacker Plates use a mechanical system which is both simple, robust and reliable. If you are a grounds work contactor, or a paving contractor, bigger really is better. Our dual direction forward/reverse Compactors will give you the size and manoeuvrability. You should have the work to justify the cost and the machines needed for the loading and unloading of your Wacker plate on site.

If you are planning on using your Compactor for tarmacking, or if you are working in an area where dust suppression is necessary, then one of our Wackers with a built-in water system would be an ideal choice.

We currently have 3 Wacker Plates in our range with built in water systems. Their primary function of a water system is for tarmacking. The water system prevents the tarmac sticking to the base plate. Wacker Plates with water systems are often good for dusty environments too so they may be worth considering even if you are not a road worker.

If you are tarmacking large areas then it may be worth opting for one of our larger dual direction forward/reverse Compactors as they will allow you to cover large areas of ground in a shorter space of time without compromising the manoeuvrability.

If you are planning on using your Wacker for tarmacking but prefer the look of one of our Wackers that does not have a built in water system then it is possible for you to have a water system fitted for an additional cost by your local Lumag dealer. Please get in contact for more information about this service, including price.

Here are some examples of how we have helped our customers in the past:

On one occasion, we had a customer call up wanting to place and order for a Lumag VP60 Wacker Plate. After a quick chat, to discuss his requirements, we established that he was purchasing the Wacker for a big block paving job and had selected the Lumag VP60 based on its price.

After going through the different compaction forces and plates sizes of the other Compactors in our range it became clear that it would make much more sense financially for him go for an Lumag RP1100PRO. This Wacker Plate was 440mm wide compared to the Lumag VP60 at 300mm, had 15Kn of compaction compared to 8.5Kn and very similar travel speeds (Lumag VP60 22m/min Lumag RP1100PRO 20m/min).

By taking the time to go through our customer’s requirements he ended up purchasing a machine that could cover the same area approximately 50% faster than with a Lumag VP60 saving him time and money.

On another occasion, we had a one-man band landscaper wanting to purchase an Lumag RP1400PRO which is our Wacker Plate with the best Kn per £). Whilst he had thought about the time savings that the bigger Wacker Plate had to offer he had not though about how he was going to but how he was going to shift around the 130 kg machine on his own?

Although all of our machines come with a FREE transport axle, moving a 130 kg machine across rough ground on your own can still hard going. After pointing out this out to him he decided he decided to go for a Lumag RP700PRO, a cheaper smaller machine. With our expert knowledge, we helped him to select the Wacker Plate that was right for him. And that’s what matters.
