Bespoke Structures
Structural Repairs
Description
Water ingress and moisture can lead to significant damage, particularly in buildings lacking proper waterproofing from the outset.
Common problem areas include construction joints, movement joints, service penetrations, cracks, and low-quality concrete.
These issues not only compromise waterproofing but can also impact structural stability through corrosion or deterioration.
Our remedial waterproofing solutions address these vulnerabilities to extend the service life of your structure.
Specifications
Our remedial services are tailored to suit the unique demands of each structure and typically include:
Targeted injection systems
Specialised grouting techniques
Crack repair and joint sealing
Waterproofing reinforcement for defective areas
All methods comply with relevant industry standards and are executed by certified, experienced technicians.
Techniques
Our primary method for remedial sealing is injection waterproofing. This involves:
Drilling angled holes (typically at 45°) on both sides of the joint to intersect at the midpoint
Injecting water-reactive resins into the joint, allowing them to fill voids and seal active leaks
We use RASCOflex Acrylic Resin Gel, a soft but compact gel that expands on contact with water. The resin does not bond to concrete but creates a waterproof seal by increasing in volume, effectively displacing water and preventing further ingress, even under pressure.
