What is the typical lifespan of concrete?
Concrete is well known for its durability and strength. When mixed, poured and maintained properly, it can last 30 to 50 years or more. The actual lifespan depends on factors like climate, usage, ground conditions and how well it's cared for. Regular cleaning and resealing help prevent surface wear, cracking and moisture intrusion. In areas with harsh weather or heavy traffic, more frequent maintenance may be needed. For most residential projects, concrete remains a long-term solution that outlasts many other surface options, making it ideal for patios, driveways, paths and more.
How long does concrete take to cure?
Concrete takes around 24 to 48 hours to set enough for foot traffic, but the full curing process takes approximately 28 days. The curing period allows the concrete to gain strength and durability. During this time, it’s important to keep the surface slightly moist to prevent premature drying, which can cause cracks. Covering with plastic sheeting or using a curing compound helps control moisture. Avoid placing heavy loads or driving on the surface too early, as that can lead to permanent damage. Patience during this stage ensures the concrete performs well for years.
Can concrete be poured in any weather?
Concrete can technically be poured year-round, but weather conditions affect the outcome. In hot weather, concrete may dry too quickly, increasing the risk of cracking. Cold conditions slow the curing process and can lead to surface scaling or poor strength development. In rainy conditions, excess water can weaken the mix. That’s why preparation is key — protective measures like curing blankets, shade or adjusting mix ratios help adapt to different weather. Planning the pour with conditions in mind ensures a longer-lasting result and minimises surface imperfections.
