All concrete structures are subject to some level of degradation over time, especially if they are exposed to significant weathering, vehicular traffic or some other external stressor.
While minor cracks or damage may not seem like a pressing issue when they first arise, solving small levels of degradation in the short term can avoid costly long-term damage to your project in the future.
To protect concrete structures from water, chemicals and other stressors, you need to select a quality waterproofing product that can deliver long-lasting durability, strength and protection.
One of these is the CMA100® Ultra Clearseal product by Scientific Waterproofing Products (SWP).
Let’s examine CMA100® Ultra Clearseal and the benefits it offers your projects.
What is CMA100® Ultra Clearseal?
The CMA100® Ultra Clearseal product is a ground-breaking formulation that interacts with the calcium within the concrete to form a water-insoluble calcium silicate hydrate gel that seals the cracks, pores and capillaries in concrete.
The CMA100® is initially applied as a liquid but once it interacts with fully cured concrete, it becomes a barrier that waterproofs and protects concrete from corrosion for the design life of the structure.

How the CMA100® Ultra Clearseal works to waterproof concrete driveways
The CMA100® Ultra Clearseal difference lies in its advanced formulation, which provides a long-lasting solution rather than a temporary fix.
It not only permanently seals existing static cracks up to 2.2mm but also remains reactive to water, effectively sealing future hairline cracks that arise.
Beyond water, CMA100® also prevents chemical damage from chloride and sulphate, which means that for concrete structures where exposure to moisture is constant, including:
- wharves
- rooftops
- car parks
- bridge decks
- marine structures
- landscaped areas
This makes the CMA100® product a comprehensive solution.
The benefits of CMA100® Ultra Clearseal when waterproofing concrete driveways
When it comes to your concrete construction project, CMA100® Ultra Clearseal offers a range of unique benefits:
- Non-toxic.
- Cost-effective.
- Fast application.
- Environmentally friendly.
- Does not require a screed.
- Seals future hairline cracks.
- No re-application is needed.
- Lasts for the life of the structure.
- Horizontal and vertical application.
- Straightforward one-coat application.
- Trafficable 2-6 hours after application.
- Cannot be damaged on-site by other trades.
- Protects against water, chloride and sulphate ingress.
- Hardens concrete to level 9 of Mohs scale (granite is 6-8).
- Increases the bond of concrete to cementitious materials by 80%.
How to apply CMA100® Ultra Clearseal to driveways
The CMA100® Ultra Clearseal product can be applied by:
- a low-pressure sprayer such as a backpack sprayer, which can apply approximately 1,000 meters squared per day, or
- a motorised pump, which can apply approximately 6,000 meters squared per day.
The average usage for every 5 square meters is 1 litre of the product, however, this figure may vary based on the specific properties of the concrete in question. For example, for linear cracks, apply approximately 1 litre per 3 lineal metres.
The method for applying CMA100® Ultra Clearseal to driveways:
- Store the product between 1ºC and 60ºC and stir before use.
- Ensure the concrete is clean, dry, cured and has a minimum of 20MPa (megapascal strength).
- Apply the product at temperatures above +5ºC and below +40ºC.
- Remove materials hindering penetration, such as curing compounds.
- Apply CMA100® until the concrete reaches saturation.
- Once touch dry (2-5 hours, climate-dependent), generously water the surface.
- Water generously again 24 hours and 48 hours after the initial watering to verify performance.
As with any construction work, it’s also important to take adequate safety precautions, such as:
- wearing protective gloves
- avoiding contact with the skin and eyes
- using a breathing apparatus in enclosed spaces
