Concrete Curb With Concrete Paver Block

Concrete Curb is commonly used for roadside, it’s used to avoid flood and also avoid driver and motorist drive onto the walkway and hurt the people on the walkway. There are many type of concrete curb such as basic curb, combined curb and gutter, integral curb, kassel curb, precast curb, landscape curb and etc. Precast concrete curb is commonly used by contractor because it’s easy to construct, save time and cost, minimize the wastage of materials.

Normally concrete curb is used on housing yard or garden, it’s used to decorate our garden or yard. Most probably it’s covering the grass or tree to make it neat, clean and decorative. Few days ago, I saw this when I travel to somewhere, I saw the concrete curb was covering a type of red paver block.

Concrete Curb With Paver Block

As you see on the photo above, the concrete curb is surrounding the red paver block. There is few simple types of paver block such as interlocking paver, landscape paver and etc. Normally paver block is made from cement, concrete and aggregate. Many people likes to use paver block instead of laying concrete slab because it’s look unique and beautiful, house owner likes to use paver block to decorate their external floor as well. Manufacturer mix it with a few different of colour to make the pavers the look of natural stone, like granite or slate.

How To Build Concrete Landscape Curb

Concrete landscape curb can be either precast or cast-in-situ. As what I mentioned in my previous article, cast-in-situ is those concrete that constructed on the spot on the site by labour. Probably concrete landscape curb is used to decorate our yard and make our yard to be different with your neighbours. Other than this, we call it as landscape edging as well. By using landscape edging for your yard, it makes your garden looks neat and clean as well.

Concrete landscape curb can be done by simple landscape curbing machine as what I show in “Concrete Curbing Machine List“. It don’t cost you a lot and it simple and fast to settle the job. It doesn’t like what I wrote for concrete road curb which curved combined concrete road curb and gutter takes you about few days to finish it.

Step By Step : How To Build Concrete Landscape Curb

I found a video from Youtube that we can learn how to build the concrete landscape curb for our yard, it’s a very simple video and it takes your 2 minutes to learn how to construct concrete landscape curb in short time.

1) Ground preparation
Ground preparation is meaning that we have to excavate a shallow with a hoe. After that, we have to make it flat and neat so that the landscape curbing machine can be move smoothly and done in short time.

2) Mixing concrete
After ground preparation, we may have to start mixing the concrete with a concrete mixer and bring it to the construction location.

3) Laying concrete
So we can now start laying concrete on the location that we want to construct landscape curbing. We will fix the landscape concrete curbing machine on the edging 1st, we need 2 persons to work on it if not the progress might be very slow. 1 person control the curbing machine and 1 person put the concrete into the machine. After put the concrete into the machine, another person will be pulling the curbing machine and the curb shape will be follow by the machine as what we saw in the video.

4) Finishing
The concrete edging is not as smooth as what we want, so we have to make it smooth with a tool. After that, we have to cut it into pieces.

5) Exposing Aggregate
In this stage, we have to expose the aggregate on the surface of curbing edging and make it stabilize and stand for longer without cracking.

6) Stamping
After that, we have to do stamping on the surface of the landscape curbing. The landscape curbing is now looks like built with small pieces of brick. The purpose of this is to make it unique and decorative. We have to do it unique because the main purpose of doing landscape curb is to make the place looks unique and decorative.

7) Spraying
Last, spray again with the aggregate and make it stable again. Done!

Conclusion

By building the concrete landscape curb, it only takes you a very short period to complete it. What you get is a very nice and unique garden, it totally looks different with your neighbours. The work is done in few hours time, it doesn’t make your place dirty and messy. It’s the easiest and simplest way to build the concrete landscape curb for your garden and yard.

Precast Concrete Road Curb

As I mentioned in my previous article, precast concrete road curb is one type of concrete road curb that manufacturer produces it in various shapes. The precast concrete road curb will be sent to the construction site when there is an usage of precast road curb.

It doesn’t like concrete landscape curb which constructed on the spot at the construction site or we called it “cast-in-site”. Of course, not only concrete landscape curb do have cast-in-situ while normal concrete road curb does have cast-in-situ by using various type of concrete curbing machine.

Why Most Of The Contractors Like To Use Precast Concrete Road Curb?

1) Time Saving
Most of the contractors like to use precast concrete road curb instead of using cast-in-situ method, one of the reasons is time saving. By using precast concrete road curb, it saves a lot of time instead of preparing all the machines, materials and workmanship to construct it on the spot at the site.

Time is everything in construction, contractor is given a time frame to complete the project. With that said, using precast concrete product saves a lot of time. In case contractor not able to complete the task within the time frame, most probably the contractor will be charged a cost by the client, in other word we called it “Liquidated Ascertained Damages” (LAD). To avoid these happen, I would say precast concrete product is one of the suitable and awesome product for concrete contractors.

2) Save Cost
Other than time saving, contractors might be able to save cost as well. In point #1, time is everything in construction, cost can be saved from workmanship. Why cost can be saved from workmanship since the manufacturer has already added this into their prices?

I make an example, let’s say contractor constructs the concrete road curb with cast-in-situ method, for a small tasks, most of the contractor might pay their workers in Day-Work method which mean contractor will pay their worker in day by day basis. In this situation, on one of the working day, that’s a raining day and workers not able to continue their works (Concrete works are not recommended to do on rainy day because the concrete takes time to become strong and stable, the quality of the concrete will be gone). With that said, contractor will be charged for 1 more working day to pay their workers. By using precast concrete road curb, the quality of the concrete can be maintained and workers able to complete the tasks in just a few hours time.

By completing the tasks within the time frame given by client, contractor will be saved and not being charged LAD by client as I mentioned in point #1.

Photos Of Precast Concrete Curb

Precast Concrete Intermediate Curb
Precast Concrete Intermediate Curb – It’s the same type of precast concrete road curb but it’s used in the intermediate of the 2-way carriageways. It’s used to distance the both roadway to avoid accident.

Concrete Grade

Normally the concrete grade used for precast concrete road curb is 20N/mm2. It’s more than enough to maintain it’s strength. The precast concrete road curb is already produce in various shape, you can simply get the information and precast concrete specifications from your local precast concrete product manufacturer.
