What is Reinforced Bituminous Membrane?

Reinforced bitumen membrane, often referred to as modified bitumen membrane or RBM is a versatile and popular roofing material that offers a range of benefits and uses in construction projects.

It is a composite material composed of bitumen (a sticky, black, and viscous material derived from crude oil) and a reinforcement layer, typically made from materials like polyester, fiberglass, or a combination of both. This combination results in a roofing material that is highly durable, weather-resistant, and easy to install.

Benefits of Reinforced Bituminous Membrane

Discover the numerous advantages of choosing Reinforced Bitumen for your project.

Durability

Reinforced bitumen membranes are known for their excellent durability and longevity. They are designed to withstand harsh weather conditions, including extreme temperatures, UV radiation, rain, snow, and hail.

Flexibility

These membranes have a high degree of flexibility, which allows them to adapt to the movement and settling of buildings without cracking or becoming damaged. This is particularly important for structures in earthquake-prone areas.

Waterproofing

As the membrane is usually built up in layers, this offers the building increased protection from the elements.

Easy Installation

Installation of reinforced bitumen membranes is relatively straightforward. They can be torch-applied, cold-applied, or self-adhered, depending on the specific type of membrane. This simplicity of installation can reduce labour costs and installation time.

Durability and Robustness:

Reinforced bitumen membranes are renowned for their durability and robustness. The combination of bitumen's water-resistant properties and the reinforcement layer's strength makes these membranes capable of withstanding extreme weather conditions, temperature fluctuations, and physical stresses. Properly installed and maintained bitumen membranes can have a of 30 years or more, depending on the quality of the materials and the level of maintenance.

Their versatility and ease of installation make them a popular choice for roofing and waterproofing applications in a wide range of construction projects, from residential homes to commercial buildings and infrastructure. Proper installation and regular maintenance are key to maximizing their lifespan and ensuring their continued performance.

Use Cases:

Flat and Low-Slope Roofs
Reinforced bitumen membranes are commonly used on flat and low-slope roofs in both residential and commercial buildings. Their waterproofing properties and flexibility make them suitable for these applications.

Green Roofs
These membranes can be used as the waterproofing layer under green roofing, providing an effective barrier while allowing for the growth of vegetation on the roof surface.

Terraces and Balconies
Reinforced bitumen membranes are often employed in areas such as terraces and balconies where there is a need for reliable waterproofing.

Our Process

01

Surface Preparation

The substrate (roof deck or surface) must be cleaned, free of debris, and properly prepared before installation.

02

Insulation

Insulation is often placed over the existing substrate to provide thermal insulation and improve energy efficiency.

03

Underlay

A suitable underlay may be applied to the substrate to provide additional protection and a smooth surface.

04

Membrane Installation

The reinforced bitumen membrane is laid out and adhered to the substrate using methods such as torching, cold adhesion, or self-adhesion.

05

Protection Layer

In some cases, an additional protection layer, such as gravel or pavers, may be added on top of the membrane for increased durability and protection against UV.

Testimonials That Speak
for Themselves

"Thank you Invictus for such a superb job."

"We cannot recommend this company highly enough. If you need to repair or replace a flat roof then this is the company to use.

Invictus was recommended to us by a seasoned building professional after we had received a bewildering array of quotes from other contractors.

Right from the start Invictus were a pleasure to deal with. Prompt, price competitive, with exceptional customer service. The work was carried out to a very high standard and the site left clean and tidy. Scaffolding was removed promptly."

Ken Brooks

"Very Impressed!"

“We have just had a major roof replacement at our School carried out by Invictus Roofing. As it was carried out in term-time, we were very impressed with the contractor and the way the work was carried out. We also had SAT’s exams week during the contract, and the team was very accommodating by changing their shift pattern to suit the school. All works were carried out to a very high quality, with all areas left clean and safe for the duration of the works. We would highly recommend Invictus Roofing and would have no hesitation in using them again.”

Fergus Walsh
Premises Manager, Carden Primary School

"Invictus Roofing fulfilled all requests"

We had a very large roof replacement completed on split sites at Hove Park School in 2017. We had a large area of the Nevill Campus roof replaced over the changing rooms and student toilets, which was conducted during the school holidays. Invictus Roofing fulfilled all requests, solved any issues, and always put our student’s needs and safety first. I would happily use Invictus Roofing again in the future.”

Danny Compton
Site Manager, Hove Park School and Sixth Form College

"Thank you for making our roof repair so painless!"

"As I sit listening to the rain hammering away at our roof I’m so grateful to know it’s all repaired & unlike three weeks ago we won’t be seeing a small waterfall in our home.

I cannot recommend Invictus Roofing highly enough, from start to finish of this job they were fabulous. A professional, knowledgeable on site team who are respectful & helpful at all times, offering calm solutions & reassurance to problems as well as being tidy & mindful of noise. (We had neighbours commenting on how courteous they were) All backed up with an efficient, helpful Office team who deal with & respond to queries quickly."
