Service information

RASCOR is a specialist in waterproofing, grouting technology, and structural repair. With decades of experience in both new-build and remedial projects, we bring expert solutions to even the most complex waterproofing challenges.

Our skilled operatives have extensive experience across a wide range of remedial applications, including:

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.

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.

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.
