Getting Ready for Winter: Your Complete Concrete Waterproofing Checklist
Waterstops Construction Joints
There are times when the construction work must pause at end of the day and when construction work resumes the next day, the new concrete section and the old concrete section should act as similar to one large slab as possible.
For those who don’t know what are construction joints, a construction joint( also called junction) is simply a type of concrete joint that is used when a new section of fresh concrete should be poured adjacent to another existing section that has already hardened and set.
Construction joints are not optional, they are crucial equipment that prevent the premature failure of concrete structures. We know that concrete has the property of expansion and contraction over time or when temperature changes, which is can result in a change in the volume of concrete. This volume change can cause concrete cracking.
So, to prevent concrete cracks, construction joints are here for the rescue. Now, why do we need waterstops then? We need waterproofing waterstops to prevent water leakage at the joints.
Should understand that there are several types of waterproofing waterstops; the most common types of construction joints waterstops are internal construction joints waterstops, external construction joints waterstops, internal expansion joints waterstops, and external expansion joints waterstops. Once embedded in concrete, they provide a water-tight connection between all cold joints.
For instance, external waterstops can be installed on the outside structure’s surfaces to prevent water from entering whereas internal waterstops are put internally inside the thickness of concrete and are often used when water pressure acts in both directions.
Expansion(or isolation) joint waterstops are vital structures designed to relieve stress on building materials caused by building movement or expansion. They can be put internally or externally depending on your project requirements.
It is critical that waterproofing waterstops are made of high-quality raw materials. Purchase the best quality waterstops available on the market now!
Bonding adhesive is an important material when talking about concrete waterproofing. It is a sort of waterproof glue for outside use and inside you, basically a super strong waterproof glue, that is used to prevent water leakages.
Waterproof bonding adhesives are mostly designed to prepare roofing surfaces for a finish coating, providing maximum concrete waterproofing.
The Benefits of Waterproof Adhesive Bonding
A fully bonded adhesive membrane forms an entire barrier between the concrete and the waterproofing membrane, preventing water from flowing through and migrating in the case of a membrane breach.
This implies that water stays excluded, allowing leaks to be targeted and rectified promptly in the worst-case scenario of a breach coincident with a fracture or weakness in the concrete, resulting in cheaper remedial measures or maintenance expenses over the life of the building.
Apart from its great filling and sealing qualities, epoxy coating’s best feature is its ability to provide a waterproof and non-corrosive protective layer.
Epoxy coating is a concrete waterproofing material but it all depends on how you use it:
- If concrete waterproofing is your primary concern, then the thickness of the layer of the coat must be enough.(2 to 3 mm)
- Curing time is also critical. The usual cure period for waterproof resins is 7 days. It is critical to ensure that the curing period does not exceed this time since the waterproof epoxy coating may break if the substrate splits.
- There are certain waterproof epoxy coatings that are more flexible than others, but each has its limitations.
- Almost generally, waterproof epoxy coating should be applied on clean, dry surfaces.
Epoxy coating would not just give a waterproof surface. Alongside, you will also benefit from corrosion resistance and durability! You can literally make a long-lasting hard layer with the right curing time and weather conditions.
However, you must exercise extreme caution when purchasing the proper epoxy; you cannot rely on any random epoxy coating brand. Picking up a pre-tested epoxy from Bardawil would yield far superior results.
If you’re tired of buying multiple sealants and adhesives, epoxy coating works like a miracle since it can operate with a wide range of materials. It is suitable for use on wood, metal, plastic, glass, and concrete!
Even a novice DIYer can use and apply epoxy coating. It may be applied with a brush, roller, or any tool you’re comfortable with just make sure it doesn’t reach your skin
You may be familiar with bitumen as asphalt. This thick, sticky liquid is best described as a syrupy version of petroleum. Because of its semi-solid structure, it is affordable, resilient, and flexible.
Bitumen is also utilized as a practical, low-cost paint that may be used to cover a broad variety of surfaces due to its various properties, which include resistance to UV radiation, harsh chemicals, and water, making it an ideal concrete waterproofing substance.
Bitumen paint (also known as bituminous paint or bituminous coating) coats surfaces to make them waterproof, weatherproof, and corrosion-resistant.
Because of its strong adhesive properties, it is common to waterproof concrete surfaces. Waterproof bitumen paint can also be used to seal cracks and make a fast repair. It works quite well in this regard because it resists contaminants and does not produce a noticeable odor once it dries.
However, there are additional benefits…
- Bitumen paint is inexpensive and commonly accessible.
- Versatile: Can be used on a variety of surfaces.
- Water and corrosion resistance: It is water & weatherproof.
- Allows for the application of many coats in a short period of time.
- It is highly durable due to its strong adhesive characteristics.

Polyurethane Based Primer Sealer(PU Primer)
For many people, polyurethane is the best waterproof solution. This material will provide a smooth waterproofing membrane. It can seal any capillary fissures providing adhesion for the full surface. It also has the potential to reduce the water absorption of concrete. It will harden the topmost surface of the concrete by penetrating very deeply
PU Primer is a penetrating polyurethane-based primer-sealer with good performance for preparing substrates for bonding or coating. It is an excellent option for concrete waterproofing.
It is an excellent waterproof material for assisting and increasing adhesion to porous concrete surfaces, and it is moisture tolerant, actively reacting and curing in the presence of moisture inside the substate.
- Easy application & Low cost
- Perfect adhesion concrete surfaces.
- High resistance to all weather conditions (-30°C /+120°C)
- Decreases water absorption of the concrete
- Hardens the concrete surface
- Recommended for concrete sealing
Rubberized Bitumen Coating
There’s a lot to like about rubberized bitumen. For instance, it is very tough. Rubber coating is a multipurpose coating that protects against moisture, exposure, and corrosion.
It can resist whatsoever Mother Nature throws at it. It is a very adaptable and versatile concrete waterproofing material. This guarantees that you will get good waterproofing results.
When applied to concrete, the rubberized coating helps reduce cracking and noise. It will also increase the underlying material’s durability.
Rubberized coating is available as sprays, dips, and liquids, allowing it to be sprayed, brushed on, dipped into, or poured. It adheres to most surfaces, particularly concrete. Once sprayed, it creates a long-lasting, protective barrier against the sun, rain, and other weather elements that can eventually destroy even the toughest materials.

Is Rubberized Bitumen Coating same as Asphalt Bitumen Coating?
If you look at these pictures you can’t even tell the difference!
People frequently use the terms bitumen and asphalt interchangeably. These two, however, are different. Asphalt is a compound composed of sand, particles, and bitumen. Bitumen is used as a binder in asphalt to hold the asphalt together, hence asphalt is a concrete mixture, whereas bitumen is a binder or cement for pavements.
Ok, Then What is EPDM Rubber?
EPDM Rubber is another highly effective concrete waterproofing material. It is a synthetic rubber material that may be utilized in a variety of applications. It is a tough class M composed of ethylene and propylene. Although it is frequently connected with silicone, the two polymers are very different.
EPDM rubber is generally used to treat roofs with a waterproof layer. It is ideal for this purpose. EPDM rubber is totally recyclable and flexible, as well as cost effective and, most importantly, efficient.
