What Is Cementitious Waterproofing?

Water damage can be a serious problem in a building, giving toxic mold and mildew a place to thrive and putting the entire structure at risk. According to data from the American Society of Home Inspectors and the Federal Emergency Management Agency, more than 60 percent of basements in existing homes have moisture problems. So, what is cementitious waterproofing?

Many residential and commercial buildings use waterproofing as a preventative measure to keep water from making its way into the building and causing issues, particularly in the basement. It can also help to reduce energy costs and strengthen the foundation of the property.

What Are Cementitious Waterproofing Coatings?

Cementitious waterproofing coatings are types of breathable coatings that can give concrete and masonry surfaces positive- and negative-side waterproofing.

Positive-side waterproofing creates a waterproof barrier on the side of the surface in question that has applied hydrostatic pressure. On a foundation, for example, this would be the outside surface closest to the soil. Negative-side waterproofing, on the other hand, protects the surface that is opposite the side that has applied hydrostatic pressure. An example of this would be the inside of a basement wall. In addition to keeping moisture out, these coatings can prevent damage from mold, mildew and water infiltration.

Benefits Of Cementitious Waterproofing

Cementitious products are considered some of the easiest waterproofing materials to mix and apply, and they provide a very solid and durable coating when acrylic additives are mixed into the cement. The materials involved are easy to obtain, and are particularly suited to wet areas like bathrooms.

Below are a few of the specific benefits this type of waterproofing offers residential and commercial properties.

Water Infiltration Damage Prevention

The main reason people turn to cementitious waterproofing is to prevent water infiltration damage, and it is highly effective in this regard. It stops the passage of water, which can save the area and its contents from all manner of water damage.

Mold Resistance

Mold is very common in homes and buildings. Any type of water seepage or excess moisture can result in the growth of mold, potentially leading to serious damage and problems with air quality. It grows particularly well on ceiling tiles, wood products and cardboard, but it can also grow in damp drywall, carpet, upholstery, paint and wallpaper.

The Centers for Disease Control and Prevention report that exposure to moldy environments can cause a range of health effects that may be severe, so it is essential to keep mold under control. Cementitious waterproofing is a reliable way of deterring mold from growing in the home.

Mildew Resistance

Mildew thrives in dark, damp and humid spaces. Like mold, it can grow on all manner of surfaces and often leads to respiratory issues and other health problems. Cementitious waterproofing in areas like basements can help to keep mildew at bay.

Types Of Cementitious Coating Products

There are several types of breathable cementitious coating products that can be used for waterproofing basements or other areas.

MasterSeal 550 offers a flexible waterproofing membrane that is suitable for above and below-grade uses both inside and outside a building. It can prevent cracking from telegraphing and accommodates substrate movement. This breathable membrane can be used on floors, walls and tiled pools.

MasterSeal 581 waterproof coating is also suited to above and below-grade applications. It can hide minor blemishes and defects in architectural concrete. The product is formulated to allow interior moisture to get out without causing damage to the coating. It can resist positive and negative hydrostatic pressure, and its finish requires very little maintenance to maintain its waterproof capabilities.

MasterSeal 582 is a waterproof coating for above-grade foundations that can also serve as a base. It can also be used for below-grade exterior masonry and concrete. This cost-effective choice provides a highly durable barrier.

MasterSeal 583 is a cement-based waterproof coating that is best suited to concrete, masonry and brick. It can waterproof basements, foundations, concrete planters, water cisterns and similar surfaces. Its semi-smooth white finish is attractive and can correct irregularities in surfaces. It also offers a high level of mildew and mold resistance.

MasterSeal 584 is a cementitious waterproof coating that can be applied to block, brick or concrete. It provides great adhesion to mineral substrates and can cover up the appearance of mortar joints to provide color and texture uniformity. It can be applied by spray or trowel.

Roof Waterproofing Using Bituminous Waterproofing Membrane Sheet

A bituminous waterproofing membrane is used for reinforced concrete roof waterproofing. This waterproofing membrane comes on site in the form of rolls manufactures and packed in the factory properly sealed. The specifications and safety manuals of this membranes provided by manufacturer should be read before installation process. Fire safety and prevention is the most important while using this membrane. All inflammable materials from roofs to be removed and good roofing practices should be followed. The bituminous waterproofing membranes are unfolded on the site and laid firmly on surface with tar based adhesives using blowtorches.

A layer of bituminous water proof membrane is laid over the structural roof which acts as a shield against the seepage of water onto the roof. Roof tiles & membrane is applied over the filler material laid to slope to pass the flow of water into drains. A proper slope is necessary to allow the water to flow steadily to drains. These membranes have 2 to 4 mm thick water proof materials. Membrane should be flexible with elongation 150 % to cover any small cracks, strong, chemical & UV resistant, flexible enough to take any shape over which it is laid.

Procedure for Roof Waterproofing Using Bituminous Waterproofing Membrane

Roof Surface Preparation

The surface to be membrane should be clear from dirt, dry and clean. Must not be installed during adverse weather and below 45⁰ F. For slope up to 3 inch the membrane should be laid perpendicular to slab and more than 3 inch slope should be laid parallel to slope. This ensures that water is never be running at joint lap edge.

Torch Equipment

Torch equipments should be properly connected and hoses to be in good working condition. Check the equipment against gas leakage by using soapy water. When torch is opened it should be at lowest possible settings to avoid sudden gush of fire.

Crystalline Waterproofing

Sealant and admixture solutions

Crystalline waterproofing is a technology that involves the development of crystals to help achieve watertight concrete structures. Master Builders Solutions crystalline waterproofing technology  is available as a waterproof coating for concrete, or an integral admixture for concrete, for use in both above and below grade applications.
