SITE LEVELING

SITE CUTS AND SITE LEVELING

How site cuts and leveling work?

Site cuts and leveling works is using earthworks machinery to re-cut the lay of the land or provide land clearing. Cut and fill excavation should be performed by experienced excavator operators, this can be the difference between getting what you want and having a bunch of issues later on. Site cuts can be used to create a level surface for a construction project, if the site isn’t cut to correct heights, this can cause a wealth of issues down the line in your construction project. At Hammer Excavations, we have performed site cuts for a huge range of projects, residential, commercial, houses, buildings, pools, landscaping, farm works, rock walls, retaining walls and just the list goes on.

What size machines do we generally use for site cuts?

Generally we will use the largest machines we can, to maximise the spoil removal rate. However, other factors must be taken into account, such as access, do you have power lines? a tight access point? such as a driveway. Underground services can also impact the size of machine we would use. We have machines ranging from 1.8tonne to 20tonne, excavators in that range would be used for your site cut in most circumstances. We also use bobcats, for spoil removal and grading. Truck will be used for the transport of spoil, an access will be created for trucks to enter and exit site in the site cut process.

Common soil types in Melbourne

Melbourne, like the rest of Australia, is far from active volcanoes, we do have some extinct volcanoes, but none that have been active for a very long time. On the surface, this appears to be a good thing. It does, however, imply that there is relatively little geological movement. Our soils are seldom replenished, and they are mostly made up of a thin layer of top soil that sits on top of deeper geological strata.

  • There are clay-rich loamy grey soils in Melbourne’s north east. Plant nutrients and humus are scarce in these soils. 
  • Shallow-dark and reddish-brown heavy clay soils with a thin loamy topsoil are more typical in the north-west. Soil structure can be improved by gypsum.
  • Heavier volcanic soils with many indigenous plants may be found near the Yarra’s mouth.
  • Dark grey sands blend with loam and clay in coastal locations.
  • There’s wet, loamy, nutrient-rich soil on the Mornington Peninsula and Dandenong hills.

“If we find rock, it can be a game changer, hard rock such as basalt and granite require using rock breakers, rock is also usually taken to different processing facilities”

How long does a site cut take?

With site cuts it can be hard to give an exact timing on how long it takes. Factors such as ground conditions, is there rock throughout the excavation site? Or is it mostly clay? Rock can slow the job down dramatically, as rock must be broken using rock breakers. Access can effect the speed of the job, does your site have limited access fro larger excavators and trucks? Generally, the larger machines we are able to use, the faster the site cut or site leveling will take.

Where do we take our excavated materials?

Soil removal or spoil removal is a key part of any site cut, all the material excavated and graded must be removed. We take care of this, using trucks, sometimes if access is ok we will use a truck and trailer. There are plenty of dump sites throughout Melbourne, all materials are taken to a permitted off-site treatment and/or disposal facility permitted off-site treatment and/or disposal facility. In the situation the spoil removed is contaminated, this will go to an official contaminated waste facility. Rock removal, rock is taken to sites that accept rock.
Material can also be left on site if that is a requirement of the owner or builder.

How do I know if my soil is contaminated?

If contaminants are present, it is likely we will get the soil tested to determine the contamination level. Contaminants can be, chemical waste, corrosive wastes, rubbish, oil, pesticides, petroleum products, radon, asbestos, lead, chromated copper arsenate and creosote. Your soil can be tested to determine the category of contamination. If the soil tests as a highly contaminated soil, it will be required to be taken to a licenced facility, we take care of all of the disposal of contaminated dirt.

How much access do we need to build a retaining wall?

As long as it is a straight line of access, we can go as low as 700mm, it really depends on the size of machine we require for the job. If we have over 2200mm that is ideal, as we can bring in a 5 tonne excavator to dig the retaining wall and perform earthworks around the site. If the site consists of rock, we much prefer to bring in a 5 tonne machine or greater. 

What size machines do we generally use for retaining walls?

Generally we will use the largest machines we can, to maximise the spoil removal rate. However, other factors must be taken into account, such as access, do you have power lines?, a tight access point? such as a driveway.

How long does a retaining wall take to build?

It does depend on the size of the retaining wall and the access, but a wall with 100 sleepers will take us approx 2-3 days with our team, in good conditions. Sometimes spoil removal and earth moving can be complicated by access, so having solid access and egress from site is preferable. We may require access for trucks and loads of materials, so access is a critical piece of the retaining wall project.

What to expect once we are on the retaining wall site

On day 1 we will double check all measurements of the retaining wall with you and go through on site the location of the wall, mapping out and planning the wall in a consultative process.  On the same day we will run through the project with you, explaining the process and ensuring we have everything we need to start constructing your retaining wall, if there are any issues we will make you aware of them at this point, to prevent issues later on.
After the consultation, we are good to go, you can leave us to build the retaining wall. You watch us work, or got to work and be amazed when you get home.

WHAT ARE ROCK RETAINING WALLS?

Retaining Walls are used for aesthetic appeal, garden, drainage, to help a drainage system, to alter the landscape of your yard, to make way for landscaping, on sloping areas, to reinforce earth, to prevent land slipping, to prevent soil washing away and many other reasons.

Using stone and boulders of all sizes and shapes, concrete, concrete blocks, natural rock, concrete sleepers, steel beams, steel h beams, stone blocks and a range of materials, retaining walls are diverse.

Retaining walls can be rock retaining walls or more commercial looking concrete walls, they can be straight, curved, vertical, used as a wall, disguised as a garden bed, natural looking, residential features in housing developments, the design possibilities are endless. Every construction company in Melbourne would have built a residential retaining wall at some stage. Retaning walls can be used to take the pressure off a house block or to split the level so a concrete slab can be poured.

Rock retaining walls or Rockwall design has become a popular look across Melbourne properties. Durable, sleek, modern and low maintenance rock walls can transform your outdoor area from a boring space to a dream. Rock retaining walls are extremely functional, helping with retaining earth, water runoff and aesthetic appeal. Rock retaining walls have been added to many landscaping projects recently and are a wonderful addition to your garden or back yard.

Using a stacked boulder approach, rock walls can be made from natural rock, limestone, mud stone, brick, concrete block, river rock and just about any solid rock you can think of. Layered and stacked, these walls are strong and can hold back a huge amount of garden bed or earth.

The primary function of these walls is to strengthen a slope, to retain the earth on a steep slope, to cut a lower level, to reinforce a site cut so that a split level can be created, often for residential projects but also for large developments. 

Rock retaining walls are now also commonly used for a decorative feature, as they add a very pleasing look to any landscape design. Curved walls are used commonly as a garden feature, no matter the material used, stone, concrete block, steel, natural rock, rock boxes, gabion baskets, masonry walls and so on, they all look pleasing to the eye.

Who is building your next retaining wall?

Drainage Systems

As a retaining wall builder, it is our opinion that retaining walls can be a garden feature, but also can be part of a more practical water runoff system in your landscape construction. Retaining walls are ideal for use in drainage, with a garden bed built in they can also catch some water. You should always take erosion into account and create projects that foresee mother natures worst before it happens. Planning is important when designing a retaining wall, allow enough ground space to lay your aggi pipe if drainage is to be a part of the system.

Land Slips

On properties where land slips or land collapse are prone, a wall like this is exactly what you need to maintain a safe area. A retaining wall can hold the pressure of the upper layer of land, giving you a safe space to build you home or shed or whatever construction project you have in mind. Curved walls can be built to maintain more space to build. In areas where the soil is unstable, a retaining wall is not best doe as a diy project, please consult a professional, it is absolutely critical that the retaining wall posts are deep enough and engineered to take the load of the land. Residential and commercial projects both need solid foundations, so does a retaining wall. It is also important to dial before you dig, and be fully aware of the location of all underground services before you excavate or dig post holes for retaining wall posts or h beams. Vertical steel beams used for retaining walls have been driven right through the soil and into a water pipe too many times, you wouldn’t want it to be an electrical underground service.

Retention Walls

Sometimes bored piers are drilled or foundations are laid to build a retaining wall. A certain amount of retention is engineered and the foundations usually have to have a certain amount of rock socket or bond length into the rock, to provide a solid foundation for the wall retaining load to be on point. Ground conditions can be different in different areas, from Melbourne vic to the outer Northern suburbs of Melbourne.

Concrete Block Retaining Wall

Using concrete sleepers or concrete block to build a retaining wall, we can build strong walls retaining earth for your next construction project. With our skills after many retaining walls built, we can put together concrete wall systems for you. 

Design And Construct

Your garden edge needs erosion control, aesthetic appeal, functionality among many other purposes and your outdoor space needs a finished product that looks the part.  There is a large difference between a natural stone wall, brick retaining walls, a timber sleeper wall, a sandstone retaining wall and commercial retaining walls, every retaining wall specialist knows that. It is in the design of the wall systems in which we layout the drainage and water runoff features of the retaining wall.
Having your walls designed by an expert get you a much better result. 
The wall location should be taken into account, and then based on ground conditions, materials, such as stone walls, timber retaining, treated pine sleeper, sleeper wall, block wall, steel posts, rock walls etc.

Sandstone Retaining Walls

Sandstone blocks are ideal for preventing soil erosion and are ideal for constructing Retaining Walls. When employing our Blocks and Logs, your landscaper or wall builder’s imagination is the only limit to the design of your Sandstone Retaining Walls.
Retaining walls are the most common. Garden edging, landscaping borders, estate walls, and even civil constructions such as marine sea sandstone retaining walls are all possibilities. You may also use use them as sandstone steps, make sitting elements out of them, or use them as garden edging. Sandstone blocks truly make a beautiful retaining wall.

Treated Pine Walls

In Australia, these retaining walls have been in use for a long time. Our research indicates that these class 1 Timber Hardwood walls, which were originally constructed from original “Old Railway Sleepers,” had a reasonably average life lifetime of roughly 15 years.

Almost all modern Hardwood Sleeper walls are H4 treated these days, and according to our research, these non-class 1 Timber Hardwood walls have a life duration of roughly 10 years.

Treated Pine Log walls are an alternative to standard sleeper walls; our study suggests that for a few additional dollars up front, you can expect to have a wall that lasts twice as long as a comparably treated hardwood wall.

Panel and post retaining wall systems have long been regarded as one of the most straightforward to construct. To build the wall, the concrete posts are first inserted into the ground to form the frame, and then the blocks are slid into place. The wall's interlocking block design allows it to be put together quickly and easily, ensuring years of endurance. They can also be utilized for nearly any height or size for your needs due to their ease of construction. You'll love the simple aesthetic and long-lasting performance our systems create, whether they're higher systems that decrease noise pollution or shorter walls for gardens. When you need a panel and post wall that will last for years, ours will always meet or surpass your expectations.

Block Retaining Walls

Block retaining walls are more of a do it yourself system, well, they come in easy to setup, interlocking systems. It still requires a certain level of technical knowledge, and it is certainly not for the inexperienced. But, interlocking block retaining wall systems are designed to produce a consistent look, all the blocks being the same size and shape. 

A block retaining wall provides a very neutral feel, by providing a consistent wall that repeats the pattern over and over again. Just like bricks, block walls are usually made from rectangular blocks. A block wall will usually have less load-bearing weight and should not be used to hold back large amounts of weight and earth.

Limestone Retaining Walls

For many people who require long-term protection and inexpensive maintenance, limestone walls are a popular choice. Limestone blocks are not only beautiful to look at, but they are also inherently flame resistant.
Solid block systems or composite blocks can be used to construct your limestone walls. Both produce a clean, long-lasting look that won’t fade and will persist for many years.
Limestone is a more expensive building material, but we can save you a lot of money on labor if you choose us as your contractor. Limestone also tends to be structurally sound for longer than other blocks, making it an excellent choice for many.

Gabion Walls

Gabion comes from the Italian word “gabbione,” which means “large cage,” which is exactly what a gabion retaining wall is. It’s made up of a series of wire mesh “cages” that keep boulders and stones in place. A gabion wall can be used as a residential retaining wall in your backyard on a smaller size.

Steel wire is used to hold the wire baskets together. Gabion walls are extensively utilized in commercial applications because they are effective and long-lasting, and they prevent soil erosion and flooding, making them a smart long-term investment. A gabion wall can be used as a residential retaining wall in your backyard on a smaller size.
