Why should I seal concrete surfaces?
Sealing concrete helps protect it from water penetration, stains, UV exposure and everyday wear. It also makes the surface easier to clean and can extend the lifespan of your concrete.
Can I use the same sealer on concrete and masonry surfaces?
Many concrete sealers are suitable for both concrete and masonry surfaces, but it’s important to check the product specifications to ensure compatibility with your specific application.
Can concrete sealers be used on new and existing concrete?
Yes, concrete sealers can be applied to both new and existing concrete. New concrete should be allowed to cure fully before sealing, while existing concrete should be cleaned thoroughly to ensure proper adhesion and performance.
Is non-shrink grout waterproof?
Non-shrink grout provides excellent resistance to water ingress due to its dense, void-free matrix formed by controlled expansion during curing. However, it is important to distinguish between water-resistant and fully waterproof: Dribond Non-Shrink Grout is highly water-resistant under normal conditions, but it is not classified as a dedicated waterproofing membrane. For applications requiring full waterproofing […]
Is Dribond Non-Shrink Grout suitable for structural use?
Yes. Dribond Non-Shrink Grout is specifically engineered and approved for structural applications, including: Grouting machine bases and equipment plinths Steel and precast concrete column base plates Anchor bolts and holding-down bolts Underpinning and brickwork repair Patching structural holes in masonry It meets Class A cement grout classification and is formulated with Portland cement, graded siliceous […]
How much coverage per bag?
Coverage varies depending on the water-to-powder ratio used and the chosen application consistency. As a general guide for a standard 20 kg bag of Dribond Non-Shrink Grout: Flowable: ~0.009 m³ (9 litres yield) per 20 kg bag | Application: Machine base grouting Plastic: ~0.009 m³ (9 litres yield) per 20 kg bag | Application: Anchor […]
What is structural grout?
Structural grout is a high-strength, load-bearing grout designed to transfer forces between structural elements — such as machine bases, steel column bases, precast concrete columns, and anchor bolts — and their concrete foundations. It must meet strict compressive strength requirements (Class A under Australian standards) and achieve void-free contact to perform under dynamic and static […]
What is non-shrink grout?
Non-shrink grout is a pre-mixed cementitious material formulated with reactive chemical agents that cause controlled expansion during curing. Unlike standard cement grout, which can shrink as it sets and leave voids or gaps, non-shrink grout maintains — or slightly exceeds — its original volume. This positive volumetric change ensures complete, gap-free contact between the grout […]
