Torch on Bitumen Systems

Our range of Reinforced Bitumen Membranes (RBM) combine strength with longevity to provide a durable waterproofing solution. Suitable for all roof applications, with a variety of options to meet all build and cost requirements, our broad range of RBM systems, bituminous membranes, base layers and vapour checks provide both time and cost efficiencies whilst retaining excellent performance levels.

Options are available for torch-on application and newly developed self-adhesive and thermo-adhesive techniques. Bitumen membranes offer enhanced flexibility, excellent fire ratings and strong reinforcement. Built-up roofing and single layer systems are available along with the Derbibrite ‘cool roof’ membrane and Derbisolar solution with integral photovoltaic cells.

Benefits

  • Bitumen is made up of organic liquids that are highly sticky, viscous, and waterproof. When used in roofing materials it provides a robust waterproofing solution with long-term durability and life-expectancy. 
  • Bauder’s bituminous membrane roofing systems incorporate SBS modified elastomeric bitumen membranes and highly efficient PIR insulation meeting current UK Building Regulations Part B for External Fire Protection. Our system application features torch-free and torch-safe installation techniques for detailing on, or adjacent to combustible materials.
  • Bituminous membrane roofing systems are durable and long lasting. They are suitable for commercial and refurbishment building projects. We have seven systems within our bituminous range . All are suitable for roofs of various shapes and sizes including green roof projects. Contact our team of specialists, they will be able to tell you which is advisable.

Roof Finishes

Ridgewell flat roofing has been installing high quality roof finishes for some time now weather is decking on a terrace to a slabbed podium or decorative floor tiles made out of liquids on a roof, the sky's the limit to how we can make the roof look once its watertight and sealed.

We have been supplying and installing green roofs up and down the country and never ceased to be amazed by the ingenuity we encounter; from the green fingered homeowner, to the eco friendly factory developer. Living roof design is based on the concept of replicating nature's blueprint. The drainage board (natures bed rock) is laid first, followed by a growing medium (or natures top soil) that is best suited to the vegetation that is planned for the desired aesthetic finish. From the 'grand design' eco home to the school development we've supplied the material and know how.

Living roof maintenance seems to be shrouded in mystery. Does a green roof need maintaining? How often? How expensive is it? Whose responsibility is it? These often unanswered questions can result in a desire to move away from having a living roof in the first place. Maintenance for a living roof needs to be considered from the outset. There is no such thing as a 'no' maintenance roof, green or otherwise. All new commercial buildings are required to have roof and gutter checks twice a year and an extensive green roof can be designed to align with this requirement. The maintenance required will depend on the outcome desired by the client.

BluRoof stormwater management 

Blue roofs are increasingly becoming the preferred solution for SuDs compliance in UK towns and cities. BluRoof is a BBA approved single source waterproofing and sustainable drainage solution which is covered by an Alumasc single point warranty.

Blue roofs – from simple rainwater storage facilities to state-of-the-art attenuation solutions – has placed this cutting edge building technology at the forefront of current thinking on sustainable drainage systems (SuDS). This shift has been driven in part by changing climate patterns (resulting in more extreme rainfall events), government planning policy, which is encouraging rainwater runoff to be controlled as close to its source as possible, and by increased awareness and information sources, such as the NFRC’s Technical Guidance Note for Blue Roofs. 

So what are blue roofs? Where can they be used? What is a blue roof and what are its main advantages? In the past, blue roofs were conceived as storage tanks for rainwater harvesting. Today, they form part of SuDS best practice and are designed to facilitate controlled attenuation following heavy rainfall or storms. Blue roofs are suitable for a wide range of building types from domestic to commercial. They place storm water attenuation within the building footprint, making them ideal for urban environments where ground space is limited. Blue roofs can be situated above the waterproofing membrane in a warm roof system or above the water flow-reducing layer in an inverted application, at both roof and podium levels.

There is a case to be made that green roofs are a form of blue roof, because they hold water and control run-off; but green roofs cannot do this in a truly controlled way such that the attenuation capacity can be relied upon to be available for a statistically derived storm event. Specifiers may like to consider the hybrid blue/green roof, which combines the aesthetic and ecological benefits of a green roof, with the high-performance water-attenuating properties of a blue roof.

Hot Melt Membrane

Hot melt membrane systems have been used in the UK roofing market for 40 years and are as robust and reliable a system as any. Predominantly used in new build projects and great for finishes to go on top such as slabs, decking, green roofs for areas such as  podium, terrace or roof, these systems are  inverted roof installations where the insulation sits on top of the hot melt.

Hot melt membrane is applied direct to a prepared structural deck to create a completely seamless roofing / waterproofing system. Hot melt can be installed on concrete, wood, metal, and most other substrates. the product can be laid to zero falls. The unique formulation of modified bitumen, synthetic rubbers, and antioxidants, combined with reinforcement, guarantees lifetime, and comes with a 30 year warranty in most cases. 

Benefits

  • ETA approved for zero fall applications 
  • Approved Document B: Fire Safety compliant
  • High performance 7mm thick system
  • Improved application
  • Engineered to last the lifetime of the building
  • Seamless monolithic waterproofing with zero tracking
  • Fully adhered with self healing properties
  • Advanced QA procedure over traditional hot melt systems
  • Approved for use beneath a variety of hard and soft landscape finishes
  • Immediately trafficable after installation
  • Root resistant without need for environmentally harmful chemical additives

Liquid Waterproofing

Liquid is a complete resin-based liquid roofing and waterproofing system. Cold applied wet-on-wet, without the fire risk of hot works, liquid waterproofing bonds directly to virtually any substrate to provide a seamless, elastomeric, UV-stable membrane. This offers distinct advantages over partially bonded, layered liquid, sheet membrane, or heat-applied materials.

Whether new build, full flat roof refurbishment or repair, in cold, warm or inverted roof applications, we are able to offer reliable long term protection that you can specify with complete confidence - whatever the substrate or application.

The success of PMMA is based on the following: Speed, Highly Reactive liquid resins are fully cured in just 30mins - 2 hours give or take. The individual layers are immediately ready for application of the next coat or for use. It takes just a single day to refurbish a balcony, for instance, and a ramp can be reopened to vehicle and pedestrian traffic in a few hours.

Benefits

  • Security - A liquid waterproofing system adapts itself perfectly to the surface, which means that it will also seal complex details and upstands to prevent water ingress and sub-surface migration.
  • It bridges movements in the substrate.
  • Durability - In terms of their chemical structure, PMMA resins are elastic, free from plasticisers and consequently lastingly extensible. According to the European Technical Approval (ETA), the service life of the roof waterproofing system is classified in the highest category (service life > 25 years).
