Many people have lived their entire lives in a house surrounded by precast walls without having to do much maintenance to it besides a lick of paint every five years or so. The sense of security and privacy it provides gives them a level of comfort in the knowledge that their first line of defence is strong and durable and will last forever. But how long is ‘forever’ and just how long will vibracrete walling last?
Masters of the trade at MFB Walling answer this question for you.
How are Quality Precast Walls Made?
Before we can discuss how long prefab walling will last, we first need to investigate how they are made, since the very answer to its longevity is the result of how it is manufactured. Precast professionals have spent decades following precise recipes of their very own blend of concrete mixtures and manufacturing techniques to produce perfect posts, slabs and panels for strong and durable walls. They have evolved through the years, adjusting these recipes with additives as modern science has developed them, further adding to the wall’s longevity. Without revealing too many secrets, we explain the process of how precast walls are made.
The quality and durability of concrete products depend on several factors, including the concrete blend ratios of sand, cement, water, certain additives, and the curing process. Curing is when the concrete mixture dries and hardens. Ideally, the perfect curing conditions are around 80 to 85% moisture at 10 degrees Celsius. In some areas in South Africa, these perfect conditions are not always available. However, the ranges of high and low humidity levels vary. If the air is not too dry and the mixture not too wet, the curing process will be just fine, delivering an ideal, quality product.
Although the basic mix of the concrete remains similar from one manufacturer to the next, certain additives may benefit the end result. Some precast walling companies add these ingredients to their mix to increase its strength and permeability. Permeability (or porosity) is the amount of water that enters the cured product. The goal is to prevent water from entering the finished product. The additives help raise the compressive strength of the product while improving its ability to resist water and moisture penetration.
At MFB Walling, the concrete pouring is done at our premises, and we can control the conditions under which the walling is manufactured to ensure that all the relevant processes are followed precisely. We also manage the curing process and ensure that the mixture is just right. Additionally, we control the quality of our products. We never allow substandard walling or concrete fencing to leave our premises – so we know that each pillar, post and slab that leaves our site will last for decades if maintained correctly.
