Concrete Curb can be done by using precast method, but sometimes contractors might choose to use cast-in-situ method too which is casting the concrete curb at construction site. By using cast-in-situ method, it doesn’t require any concrete curbing machine. With that said, the cost can be save from here without using any machinery.

In constructing a longer straight concrete curb at the construction site, it might requires more workers to complete the job on time. With that said, the cost will be increasing on this part. Other than this, contractor must ensures that the workers can complete the casting and make it in shape because the concrete will be fixed in certain period.

How To Build Concrete Curb By Hand

1) Build up the mold or formwork which is in concrete curb shape.

2) Mixing the concrete in correct mixture.

3) Pouring the concrete into the mold or formwork just now.

4) A few of workers are starting to smoothen the concrete curb with a timber plank. Workers must compact the concrete curb so that it won’t be collapsed or cracked easily. Workers must complete this task as soon as possible before the concrete fixed in shape.

5) After the workers have done the concrete works, they might need to take off the formwork or mold after the concrete is fixed in shape. Job is completed and workers have to continue other works like drainage system.

Recently I saw a concrete curb on the roadside and find out that the concrete curbing is installed with the steel barrier rail. As we can see, the steel barrier rail is installed on the top of concrete road curb, we rarely can see this type of road curb on the roadside because it requires a high cost for the steel barrier rail.

Purpose Of Using Concrete Curbing With Steel Barrier Rail

To construct concrete road curb together with steel barrier rail, it’s costly and rarely we use it. Of course, we still have to use it on certain area because of client’s requirements. Most probably we will use this steel barrier rail on the busy roadside, which means there is a lot of cars and lorries using the road. If there is many cars and lorries using the road, it may hurt the people who walks on the walkway. With that said, the steel barrier rail is to avoid cars and lorries drive onto the walkway and bang the passenger on the walkway, it’s very dangerous.

How To Construct Concrete Road Curb With Steel Barrier Rail

It’s not complicated to construct concrete road curb with steel barrier rail.
1) As usual, you have to just construct the road curb with concrete curbing machines. As you see, this is a cast-in-situ road curb but not a precast road curb, we can determine it from the shape. The photo below is the precast concrete road curb, it comes with smaller piece and in shape.

2) Secondly, install the steel barrier rail. Normally you can get it from steel manufacturer and it comes in shape. So, you just have to make it straight on the top of road curb. As you see at the photo above, there is a few post at the steel barrier rail, you drill with 4 steel screws on the post and attach it on the road curb. The same step for other post until you finish it. You don’t have to use stainless steel because the cost for it will be very high and might burst your budget.

3) That’s it, you have done it and it looks great!

It’s very simply and easy to install the concrete road curb with steel barrier rail, the cost is not high and you can protect the passengers on the walkway. Normally it’s required by your client.

What is Concrete Road Curb

Concrete road curb is the road edging where a flat pavement or path meets an unflat street or walkway, the level of both roads is different and the water will flow to the lower level portion.

It’s one type of concrete curb called combined curb and gutters. It’s commonly used to overcome the flooding problems.

Normally road curb is made from concrete, stones, alphalt and etc, but concrete and alphalt are commonly used for road curb in construction industries. Wherever you go on the road, you can see the concrete road curb besides the walkway.

Photos Of Concrete Curb At Site

Below is some photos that I took while I went to site. This is a very simple concrete curb.

- Straight Concrete Road Curb -

- Curved Combined Concrete Road Curb And Gutter -
[It's same with straight concrete road curb but it's just constructed follow the road line]

- Direction Of Flow And Concrete Slab Cover -
[There will be a small hole that allows the water flows in into the drainage]

- Drainage System -
[The water will flows into the drainage system]

Function Of Concrete Road Curb

There is a few of function and usage for the concrete curb at the roadside. There will be a few purposes of installing concrete curb :

i) Avoid Flood
It’s works as a gutter that allows the water flow in by lower road level and flow into the drainage.

ii) Safety To Driver And Motorcyclist
If there is no concrete curb there, driver might drives onto the walkway and people on the walkway might get hurt. Other than this, if there is no concrete curb as a drainage system, there must be flood when raining, the water might stopped at the roadside without flow into the drainage in proper way. It’s very slip, when motocyle or car pass by, the tires can be slip and cause them to lose visibility and ability to brake and stop down, it may causes an accident.

Type Of Concrete Road Curb

i) Basic Curb

That’s very easy to construct basic concrete curb because you don’t have to joint it with gutter, it’s a straight concrete curb. But it’s rarely used it can’t helps to overcome the flood problems, it’s only used in minimal location.

ii) Combined Curb and Gutter

This type of concrete curb is a combination of curb and gutter, the photo above shows that the gutter is used for the water flowing into the drainage system. This is commonly used in driveways everywhere.

iii) Integral Curb

This type of concrete curb are constructed as a part of sidewalk too. As you see in the photo above, the concrete curb is joining concrete sidewalk. Normally it’s cast-in-situ, which mean the concrete curb is constructed on the spot at the site.

iv) Kassel Curb

Kassel curb is purposely constructed for the buses especially in bus stops. Normally the basic concrete curb has a lower level and it’s difficult to passenger to enter the bus which has higher steps. Kassel curb has been raised up to improve accessibility for mobility-impaired passenger.

v) Precast Curb

Of course, there are some precast concrete curb too which is produced in the factory and bring to site whenever there is an usage of relevant concrete curb. Precast concrete curb will be used if the client need a faster completion of work, of course the prices for those precast concrete curb will be slightly higher than cast-in-site curb.

Pattern Of Concrete Road Curb

There is many patterns for concrete curb, as you see in the photo above, there are angle, round, mower, multi lighted, angle lighted, walkway, parking, square, wheel block and etc. Rounded concrete curbs are most commanly used for driveways that the sidewalk has grassy setback from the street.

The photo named “Straight Concrete Road Curb” above is using a wheel block concrete curb, while this pattern are commonly used for the sidewalk that lay with premix.
