This document discusses various common waterproofing methods used in construction, including cementitious waterproofing, liquid waterproofing membranes, bituminous membranes and coatings, and polyurethane liquid membranes. Cementitious waterproofing uses easily available cement-based materials and is commonly used internally, while liquid membranes form flexible rubbery coatings. Bituminous membranes are popular for low-sloped roofs and come in torch-applied and self-adhesive types. Polyurethane liquid membranes offer high flexibility but are more expensive and sensitive to moisture levels. The document provides details on the materials, applications, advantages and limitations of each method.
It is essential to waterproof a structure to prevent the seepage of water for its durability. We provide water proofing solutions for basements, sunken portions, roofs, terrace gardens and expansion joints etc. We deal with several ways of water proofing depending on a structure, site and conditions viz.:
Polymer Modified Cementitious Membranes
Polyurethane Membranes
Box Type Method using Kota/Agra Stone
Injection Grouting
APP modified bituminous membranes / Trafelt
EPD Membrane

What is Bitumen membrane waterproofing?
Bitumen membrane waterproofing is a way used to protect buildings and structures from water penetration. It includes the application of bituminous (asphalt-based) membranes to various surfaces, such as roofs, foundations, and walls. These layers are made of bitumen, which is a sticky and viscous form of petroleum.
There are different types of bitumen films, including:
1. SBS (Styrene-Butadiene-Styrene) Modified Bitumen Membranes: These are flexible and durable membranes that can withstand temperature changes and movements in the underlying structure.
2. APP (Atactic Polypropylene) Modified Bitumen Membranes: These membranes have added polypropylene, enhancing their resistance to UV rays and giving better flexibility in cold temperatures.
3. Self-Adhesive Bitumen Membranes: These membranes come with a self-adhesive backing, making them easy to install by simply peeling off the protective layer and sticking them to the surface.
The application of bitumen membranes provides a waterproof barrier, stopping water from seeping into the structure and causing damage. It's widely used in roofing systems, basements, and other areas prone to water exposure.
So, in a word, bitumen membrane waterproofing is like giving your building a sturdy raincoat to keep it dry and happy.
Why is bitumen membrane waterproofing one of the best waterproofing services?
Bitumen membrane waterproofing has gained fame for several reasons that contribute to its effectiveness as a waterproofing solution:
1. Durability: Bitumen membranes are known for their durability and ability to resist various weather conditions, including extreme temperatures and UV exposure. This durability provides a long-lasting waterproofing solution.
2. Flexibility: Many bitumen films, especially those modified with polymers like SBS or APP, are flexible. This flexibility allows them to adapt to the movement and settling of the building without losing their waterproofing capabilities.
3. Adhesion: Bitumen membranes often have excellent adhesion qualities, ensuring a strong bond to the substrate. This stops water from finding its way through seams or gaps, providing a reliable barrier against water infiltration.
4. Versatility: Bitumen membranes are flexible and can be applied to various surfaces, including roofs, foundations, and walls. They are ideal for both new construction projects and as a solution for waterproofing existing structures.
5. Ease of Application: The application of bitumen membranes is usually simple, especially with self-adhesive variants. This can reduce the complexity and time needed for installation compared to some other waterproofing methods.
6. Cost-Effectiveness: Bitumen membrane waterproofing is often considered cost-effective in terms of both supplies and installation. This makes it an attractive choice for a wide range of construction projects.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. INTRODUCTION
There are some common types of waterproofing methods used in construction
industry. Waterproofing in buildings / structures are generally required for:
Basement of structure
Walls
Bathrooms and kitchen
Balconies, decks
Terrace or roofs
Green roofs
Water tanks
Swimming pools
2
4. Cementitious Waterproofing Method
Cementitious waterproofing is the easiest method of waterproofing in construction. The materials for
cementitious waterproofing is easily available from suppliers of masonry products, and they’re easy to mix
and apply.
This method is often used in the internal wet areas such as toilets. This method is usually a rigid or semi-
flexible type waterproofing, but since it is used in internal areas such as toilets, it is not exposed to sunlight
and weathering.
4
5. CONTI..
Thus cementitious waterproofing does not go through contract and expansion process.
Cementitious waterproofing is used in the following type of structures:
Water Treatment Plants
Sewage Treatment Plants
Bridges
Dams
Railway & Subway Systems
Marine Cargo Ports & Docks
River Locks/Channels & Concrete Dykes
Parking Structures & Lots
Tunnels
5
6. Liquid Waterproofing Membrane Method
Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats
which are applied by spray, roller, or trowel. It offers more flexibility than the cementitious types of
waterproofing.
The liquid cures into a rubbery coating on the wall. The elongation properties of the coating can reach
as high as 280%. The durability of the waterproofing coating depends on what type of polymer the
manufacturer use for the making of the liquid waterproofing.
6
7. CONTI..
Liquid waterproofing membrane can be of spray-applied liquid membrane
composed of polymer-modified asphalt. Polyurethane liquid membranes in
separate grades for trowel, roller, or spray are also available from various
manufacturers.
7
8. Bituminous Coating Waterproofing Method
Bituminous coating is a type of coating used for waterproofing and flexible protective coat in accordance with its
formulation and polymerization grade. Its flexibility and protection against water can be influenced by the
polymer grade as well as reinforcement of fiber. Bituminous coating is also called as asphalt coating.
The most common applications of bituminous coatings include areas that are beneath screed wet. It is an
excellent protective coating and waterproofing agent, especially on surfaces such as concrete foundations.
Bituminous coating is made of bitumen based materials and it is not suitable for expose to sunlight.
8
9. CONTI..
It becomes very brittle and fragile when long exposure to the sunlight unless it is
modified with more flexible material such as polyurethane or acrylic based
polymers. The flexibility of the finished products always depends on the solid
content of the polymer added to the bitumen.
9
10. Bituminous Membrane Waterproofing
Method
Bituminous membrane waterproofing is a popular method used for low-sloped roofs due to their proven
performance. Bituminous waterproofing membrane have torch on membrane and self-adhesive membrane.
Self-adhesive compounds comprise asphalt, polymers and filler; additionally, certain resins and oils may be
added to improve adhesion characteristics. The self-adhesive type has low shelf life as bonding properties of
the membrane reduces with time
10
11. CONTI..
Torch on membrane have exposed and covered types. Exposed membrane often
has mineral granular aggregate to withstand the wear and tear of the weathering
and the other types of membrane, contractor need to apply one protective screed to
prevent the puncture of the membrane.
11
12. Polyurethane Liquid Membrane Waterproofing
Method
Polyurethane liquid membrane method of waterproofing is used for the flat roof area and exposed to
weathering. This waterproofing method is expensive. Polyurethane Liquid Membrane can offer higher
flexibility.
Polyurethane is very sensitive to moisture content present, therefore before application, one has to be very
careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes
may happen after some time.
