LIQUID APPLIED MEMBRANES:

Liquid Applied systems can be both Solvent and Water based materials. These may have base of Polyurethane, Rubbers, Bitumen, Acrylics and /or a combination of these. These are in liquid form and after curing form a seamless sheet. 

Liquid Applied systems are positive side waterproofing application and require a protective layer before backfilling. These are used primarily because of ease of application, seamless curing, and adaptability to detailing. These systems are popular for basement, podiums, planters, and garden application. The systems used for basement waterproofing are not UV Stabilized and cannot withstand foot traffic. These systems typically have an elongation of over 400% with recognized testing as per ASTM C 836. This enables these systems to bridge cracks <2mm. The Liquid Systems have self- flashing capabilities which enables these to be applied seamless at substrate protrusions, changes in planes and floor wall junctions. 

Advantages of Liquid Applied Coatings:

1. Seamless / Monolithic Membrane
2. Shorten Installation Phase
3. Superior Waterproofing
4. Adaptable to detailing
5. Excellent Elastomeric properties
6. Ease of application

Disadvantages of Liquid Applied Coatings:

1. Application thickness controlled at site
2. Some products can not apply on wet surfaces

Cementitious Systems:

Cementitious materials are excellent products to be applied on below grade structures, both positive and negative sides. These systems are based on a mix of Portland Cement with or without sand and an active waterproofing agent. There are two types of cementitious systems: Crystalline System, Acrylic Modified Systems. These are applied using brush or trowel to the concrete or masonry surfaces and become integral part of the structure.

In the under-construction buildings, the biggest benefit of using a Cementitious system is that it does not need a dry surface. In fact, some moisture in the structure helps the system and improve its efficacy. It can also be applied if the concrete is not fully cured. These systems can be applied to both the walls and floor

All cementitious systems have similar application method. The performance may differ from product to product depending upon its formulation. The Cementitious systems lack crack bridging or elastomeric properties but have great adhesion to the substrate.

Advantages of Cementitious Systems:

• Positive or Negative Side application
• Remedial/ Repair Application

Disadvantage of Cementitious Systems:

• No Movement Capability
• Site Mixing Required
• Can Not be used in high traffic areas

CrystoSeal 1K

CrystoSeal 1K is a single cementitious component powder, which when mixed with water forms a chemically active slurry that functions on the principle of crystallization. It is composed of a cementitious binder, well graded fillers and a combination of active chemicals and additives. Due to its formulation, the active substances in SS – CrystoSeal 1K penetrates the substrates by osmotic action, hydrates to form insoluble crystals and thereby blocks the penetration of water into the substrate, through capillaries and cracks. SS – CrystoSeal 1K is not very flexible, and hence is most suitable for waterproofing of indoor areas, masonry structures and as a dry-shake broadcasted material for RCC floor slabs. SS – CrystoSeal 1K forms a breathable (allows water vapor diffusion) cover that forms an integral part of substrates and shows extreme resistance to water ingress, both on the positive as well as negative side. It reacts with any free lime present in the substrate to form denser hydrates, which prevent any movement of water. This feature drives its use as a material that can be broadcast on a fresh cast floor slab. The slab so treated, when finished and cured, shows extreme resistance to water ingress. Being mineral in nature, its breathability and thermal characteristics are like the underlying substrate, assuring a long-lasting protection against water. SS – CrystoSeal 1K can be used in bathroom, wet areas, water tanks, masonry basements, Basement slabs, lift pits and many such applications.

CrystoSeal Flex

CrystoSeal Flex is a two-component cementitious system, comprising of a powder and a liquid component, which when mixed forms a chemically active slurry that forms crystalline hydrates and a flexible, water-resistant membrane due to the polymer component.

These are used to seal the joints between two substrates, Vertical and Horizontal Joints, Expansion Joints, Construction joints and cracks, Future movements of the construction without causing damages, Basements, Tunnel construction, Around metal surfaces, Swimming pools, Cable and pipe penetrations, Sewage treatment plants

EXTERNAL MEMBRANES:

External Membranes are Sheet or Pre-Formed membrane systems are reliable and durable waterproofing solution that can fulfill the requirements of even the most severe and demanding below ground structures. These are popular choice as these can withstand elevated level of ground water pressure, aggressive chemicals present in soil or water, dynamic forces due to earthquakes and ground settlements.

The sheet membranes come in fixed and controlled thicknesses, widths, and lengths. These range in thicknesses ranging between 1mm to 5mm and widths ranging between 1.0 mtr to 3.0 mtr. 

Application of Pre-Formed Membranes, in the basement requires protection during backfilling, Steel Binding and Concrete Pouring. Some manufacturers, in the recent years have started offering products for below the raft application, which they claim to not need any protection from Steel Binding and Concrete Pouring. Unlike Liquid Applied Membranes, Preformed Membranes have multiple joints and are not seamless. These are also not self-flashing at protrusions and junctions. Same is the case at the termination pr transition into another section of the building envelope. Being too heavy these are limited for application on the horizontal surfaces. Vertical single ply membranes are more difficult to apply then the Liquid Applied membranes. It is difficult to handle and joining the materials. The seams are lapped and sealed for complete waterproofing, particularly in small areas such as planters.

Different Types of Membranes are.

• APP: The APP membrane, short for Atactic Polypropylene Membrane, is a special waterproofing material that is manufactured from Bitumen. APP membranes comes in rolls, measuring 10 mtr x 1mtr. With proper workmanship, the APP membrane is a very efficient and durable waterproofing material used in most constructions. It is a common material sed on concrete flat roofs. These are also used for waterproofing of concrete gutters, basements and retaining walls.
• SBS: The SBS Membrane is a bituminous waterproofing membrane manufactured by blending a mixture of bitumen and SBS (Styrene Butadiene Styrene) polymers to obtain excellent waterproofing and low temperature flexibility properties. The polymerized bitumen is coated onto a dimensionally stable reinforcement core of non-woven spun bond polyester rot-proof fabric. The membrane has excellent tensile & tear strengths and is highly resistant to puncture. It is flexible and is suitable for applications where high structural movement is expected.
• HDPE: HDPE Membranes are based on high-density polyethylene material, designed to provide water and water vapor protection to water excluding structures, securing concrete from aggressive ground salts and chemicals related corrosion.
• TPO: Thermoplastic Polyolefin Membranes are single-ply roofing membranes that are one of the fastest-growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs. TPO membranes are manufactured in sheets that are 10, 12, or 20 feet wide. These sheets are then rolled up and taken to the commercial facility. TPO has gained industry acceptance with the natural reflective surface to reflect UV rays. These are generally used in large Industrial and Commercial segments.
• EPDM Rubber: EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) used in various low-slope buildings and basements worldwide. Its two primary ingredients, ethylene, and propylene are derived from oil and natural gas.
• Composite Plastic: Composite Plastic membranes bring sustainability to the construction industry, using recycled plastic. Anchor Grip Composite Plastic Membranes are plastic sheets with closely spaced L-Shaped locking extensions called Anchor Grips. These are best suitable for Basements and Retaining Walls.
• Non-Bituminous Composite Membrane: is a membrane developed for internal and external waterproofing where a covering must be applied in areas like kitchen, toilets etc. where water ingress is expected. It consists of Bituminous compound reinforced and protected on both sides with Non-Woven Propylene. These are thin and flexible and are compatible with all cement screeds.
