Services

Two focused services, with repairs assessed for the conditions on site.

01

Water leakage repair

Water leakage can have many causes. Applying a waterproof coating without a diagnosis only treats the symptoms. Our approach is to diagnose first, then carry out the work, precisely locating leaks at external walls, windows or bathrooms. Depending on the cause, we use high-pressure grouting, reinforced junction detailing or replacement waterproofing layers. We select low-carbon, environmentally friendly materials with CIC green certification to stop water at its source and protect a dry, healthy, leak-free home.

  • Water ingress at windows and external walls
  • Bathroom and ceiling leaks
  • Roof waterproofing and leakage repair

02

Concrete Spalling Repair Works

For spalling concrete on ceilings and walls, we address both the visible damage and its underlying cause. Our craftspeople remove loose concrete back to a sound base, clean rust from the reinforcement and apply a rust-inhibiting primer. High-strength structural repair mortar is then applied in layers, followed by waterproof and anti-carbonation coatings. This rigorous process stops further reinforcement corrosion and restores a sound, secure home.

  • Assessment of loose concrete and exposed reinforcement
  • Repairs and surface treatment to affected areas

GREEN MATERIALS

Better waterproofing starts with material selection

We prioritise waterproofing materials with CIC Green Product Certification where suitable, considering both waterproofing performance and environmental criteria when planning the work.

  • Select materials for the substrate, cause of leakage and site conditions
  • Check the product model, certification and manufacturer’s requirements
  • Confirm materials and associated work in the quotation
