Upgrading your Boundary Wall
When it comes to walling solutions, there are times when starting from scratch isn’t necessary. At Alfa Concrete Walls, we offer a practical and cost-effective way to upgrade your existing boundary with our professional wall extension service. Whether your goal is improved security, privacy, or aesthetics, extending your wall is a smart and seamless solution.
We specialise in raising existing precast walls by 300mm, 600mm, or 900mm, depending on your needs. Our service is designed to help clients reach this limit safely and professionally — without rebuilding the entire wall from the ground up.
OUR WALL EXTENSION METHOD
Our wall extension method is both durable and discreet. We use prepared angle iron, which is securely fastened to the existing wall structure, creating a strong base for the new upper section. This angle iron serves as the framework to support new short precast pillars, which are then aligned with the existing wall and used to anchor the extended slabs in place.
While the extension process is efficient, it’s important to manage expectations when working with an existing structure. We extend “as is,” meaning that if your current wall is skew or misaligned, the extension will follow the same line. Additionally, colour variations between new and old panels are common due to weathering and time. Though this does not affect the wall’s strength or functionality, we always communicate these details clearly with our clients beforehand.
We also inform customers that new pillars may differ slightly in size or shape, as moulds may not match the originals exactly. A visible joint line may appear where the new and old components meet — a normal part of any wall extension process.
RAISING THE STANDARDS
At Alfa Concrete Walls, we take pride in offering honest, transparent, and high-quality workmanship. Wall extensions are not just about raising the height — they’re about raising standards. For homeowners and businesses looking to improve their properties without the cost of replacement, this service offers immediate value.
