Service Parameters

5 Yrs System Warranty 20 Yrs Expected Lifespan
Installation of a protective firewall system using Tecnatorch SBS Torch-On Mineral Felt Charcoal. This system replaces ineffective coatings and Acrypol with a durable layer of high-performance modified felt. The material features exceptional flexibility, allowing it to bridge and seal existing micro-cracks in the wall structure. Unless the masonry is severely deteriorated, this method effectively replaces the need for costly re-rendering. The result is a watertight, aesthetically matched finish that stops moisture from penetrating the building interior. The SBS modification ensures the felt remains flexible in freezing temperatures and stable in the heat. It is the most technically advanced solution for keeping roof parapets dry and in perfect condition for the long term without further maintenance.

Mechanical Surface Preparation & Cleaning
Mechanical Surface Preparation & Cleaning

Mechanical surface preparation using a steel wire brush to ensure maximum adhesion for subsequent layers. This process involves the thorough removal of moss, lichen, loose old paint, and any friable or unstable material from the substrate. Cleaning down to a solid base prevents future delamination and the formation of air pockets. This preparation is essential for creating a perfect bond between the existing structure and the new insulation or coating. A clean and stable surface is a key factor in the overall lifespan and reliability of the completed repair.

Included
Bitumen Primer: Material Application
Bitumen Primer: Material Application
Cromar

Applying a bitumen primer is a crucial preparation step before installing the new waterproofing system. This liquid coating seals the existing substrate and locks in any remaining dust. Its main purpose is to create the perfect conditions for the first layer of felt to adhere flawlessly. This guarantees a strong, permanent bond between the treated surface and the felt.

Included
Ladder Access Work (Scaffolding Not Included)
Ladder Access Work (Scaffolding Not Included)

This service includes access using standard ladders or a hook ladder. Many repairs can be carried out efficiently without the need for scaffolding, saving both time and cost. However, safety is always our priority. If site conditions do not allow safe ladder use (e.g. limited space or difficult access), scaffolding may be required and is not included in this price.

Long-Term Waterproofing for Parapets and Firewalls: Why Felt Capping is the Professional Standard in Sussex

For boundary walls and roof parapets in coastal areas like Brighton, Hove, and Worthing, moisture penetration is one of the most persistent issues homeowners face. While masonry paint or liquid membranes like Acrypol are often used, they frequently fail due to the natural thermal expansion of the building. In contrast, torch-on felt capping is a technically superior solution, proven by decades of practice in the British construction industry.

Proven Masonry Protection Without Frequent Maintenance

This system utilises Tecnatorch SBS Torch-On Mineral Felt, a high-performance material engineered for extreme durability. Unlike liquid coatings, this felt layer is thick and flexible enough to bridge structural cracks and withstand the movement of the building.

In practice, provided the masonry is not in a state of total collapse, felt capping effectively replaces the need for expensive and time-consuming re-rendering. It creates an airtight, waterproof seal that prevents bricks from absorbing water—a critical factor in the damp Sussex climate for maintaining a dry interior.

Full Documentation via Your Client Portal

With this type of structural work, it is vital to know that critical joints and cracks were properly treated before the final layer was applied. For every approved order, I follow a standardized documentation process to ensure full transparency:

  • Substrate Preparation: Photos of the wall after mechanical cleaning and primer application.
  • Work in Progress: Documentation of the torching process and the sealing of corners and overlaps.
  • Completion: The final state of the protective mineral layer.

All records are uploaded in real-time directly to your secure Client Portal. This provides you with a complete photographic log of the project, serving as clear evidence of the technical quality and the depth of the remediation performed on your property.

An Efficient Solution for Sussex Property Owners

Felt capping is the preferred choice for those seeking a long lifespan with zero maintenance requirements. The Charcoal Mineral finish is highly resistant to UV radiation and mechanical wear. For property owners in Brighton, Worthing, and the surrounding areas looking for a functional barrier against damp without the need for annual repainting, felt capping represents the most technically advanced and reliable option available.
