Precast concrete is a method used in the construction of concrete building materials in a controlled manner. Special moulds are used in which the casting is done to create, for instance, kerbs. The precast kerbs are then transported to the place where an installation is required.
Several functions of kerbs include, but are not limited to:
- Delineation of the pavement edge.
- Separation of the walk area from the vehicle travel path.
- Discouraging motorists from parking or driving on the paths demarcated for pedestrian or cycle use.
- Prevention of unauthorised parking on lawn areas.
- Support to the edge of the pavement area.
- Aesthetic appeal of pavement areas.
- Separation of the parking lot from the driveway.
- Channelling stormwater to the drainage areas.
Benefits of Precast Concrete Kerbs
Instead of casting the kerb structures at the installation site, the pre-manufactured sections are made in a special plant. This holds several benefits, including the ones discussed below.
Reduce Construction Time
Projects are often delayed because of weather elements, especially when working with building materials such as concrete. Casting the kerbs at the roadside takes time, especially because each section must be cast separately. The cement must dry, and this also takes time. Other tasks are delayed until the kerbs have dried. With the precast structures, earthworks and other important tasks in road construction can continue as the kerbs can be installed at the same time.
Pre-Stressed Material for Structural Strength
The material used has good structural integrity and can thus bear heavy loads. Testing is already performed at the plant to ensure compliance with strength, manufacturing, quality, and safety requirements.
With installation easier and quicker, labour time is saved. This means a huge saving on labour costs. The reduced time in installation also means faster completion of projects, and thus a reduced risk of project lag time with penalties payable.
Consistency in Quality
Inconsistencies in quality are a given if the products must be made at the site. Quality control is difficult. Such inconsistencies can lead to poor quality work on some sections, affecting structural integrity, aesthetic appeal, and the safety profile of the work. With precast work, the mould types, lengths, temperatures, climate, mixes and curing processes are monitored. As such, improved quality is the result.
Precast concrete kerbs have long service periods and require little to no maintenance. The density of the material adds to product durability. The final product is robust enough to handle threats of corrosion, dust build-up, acid spills and vehicle impact. The controlled curing process helps to improve structural strength and consistency of the kerb.
Neat and uniform in design, the products are visually attractive. The same texture, colour and form are possible for every section as the product is made in a controlled manufacturing environment. The shapes and sizes are consistent, and the finishes are neat.
Safer Work Environment
With on-site product creation, materials must be transported and stored. Such materials at the roadside pose a danger to road users. There is also the risk of materials being stolen at the site. With precast concrete kerbs, there is no need for additional materials. The products can be installed quickly. This reduces the risk period for theft and work accidents.
Flexibility in Design
It is possible to request specific lengths, sizes, shapes, textures, and colours from the manufacturers.
Where to Buy Precast Concrete Kerbs
We manufacture the products through a wet-pressed method for maximum consistency, strength, and durability. This also enables us to produce large quantities and thus offer competitive prices. We use a single mix to ensure colour consistency. Get in touch for more information about our range of precast concrete kerbs and the affordable pricing for each type.
