Precast concrete is one of those things that sounds simple, like something that the average person could easily look past on any given day. But, when you’re considering building or renovation work – or if you have experience on a building project – you’ll find yourself incredibly grateful for the skill and ingenuity behind them.
What Precast Actually Means for Construction Projects
The alternative to precast concrete is, of course, concrete that is poured and left to set on-site.
From the perspective of those working on-site, casting concrete off-site means that other parts of construction can proceed without the time delays and space restrictions posed by drying concrete. Active building sites are busy and, at times, chaotic places, and concrete pours can cause a lot of disruption, leading to higher labour costs and longer delays.
But there are other benefits to pre-casting concrete off-site, too. In factory conditions, elements like temperature and moisture exposure can be controlled far better than they can be outdoors, which means that the concrete comes out at a much higher quality, more durable, and with far greater consistency, too.
Tailoring the pre-casts to the exact requirements of the site is also easier in a factory overseen by experts who know how to meet the standard required by the site.
What’s more, precast concrete strengthens before it arrives on-site, which is a huge benefit – particularly when schedules are tight.
Why Extensions Are Turning to Precast Solutions
Precast concrete is incredibly versatile and strong, which makes it ideal for being shaped to the exact requirements of the site. Architects have a lot of ‘wiggle room’, even with complex landscapes, when it comes to using pre-cast concrete.
Modular retaining wall systems made from precast concrete, for instance, are highly effective at building ‘into’ uneven landscapes, which is particularly useful for home extensions. Rather than being limited by the shape of the land around the home, builders and architects can utilise retaining walls to create more space for work.
Plus, extensions often pose a logistical challenge to builders: space limitations. With homes, garages, gardens and boundaries already firmly in place, the ability to create tailored solutions off-site is a huge benefit, and makes more ambitious projects possible.
Where Precast Fits in a Renovation
Precast concrete comes in many different forms. Perhaps most commonly, it’s found in the form of modular retaining walls on all manner of sites, from domestic properties to warehouses and fulfilment centres – and many different builds in between.
But precast concrete can also be used for the bones of buildings, such as staircases and lift shafts.
While many sites still pour concrete in situ, the benefits of ordering bespoke systems created in quality controlled environments – and overseen by experts in the field – are clear to see, and it’s no wonder that many renovators and architects are opting for these deceptively simple alternatives.
