Description
This webinar presented modern, minimally invasive techniques for assessing and repairing masonry defects, emphasising structural reinforcement through helical systems and cost-effective alternatives to traditional rebuilding.
Key Points
- Common masonry issues, including thermal movement, subsidence, steel corrosion, and wall tie failures, can often be addressed without full-scale demolition.
- Helifix systems utilise stainless steel helical bars, injection grouted ties, and masonry beams to reinforce and stabilise structures while preserving aesthetics.
- Modern underpinning and pile systems offer low-disruption, environmentally friendly solutions for foundation movement, reducing the need for costly rebuilds.
Learning Objectives
- Identify typical structural defects in masonry and distinguish between their causes (e.g., thermal movement, subsidence, corrosion).
- Understand the principles and applications of non-disruptive reinforcement techniques such as crack stitching, masonry beams, and helical bars.
- Evaluate modern underpinning and piling strategies as cost-effective alternatives to traditional structural repairs in historic and residential buildings.
