A lot of people believe concrete doesn’t need any protection. Truth is, it isn’t. Bit by bit, moisture and dust find their way into the surface. It doesn’t crack right away, but the damage quietly builds up over time. That’s where concrete sealants make a difference. Once applied, they block out water, dust, and other things that slowly eat away at the surface.
Roka Backer Rod is a closed cell, extruded polyethylene foam backing rod, used as a backing material for different sealants to give the correct thickness.
Roka Flex Band is a highly resistant and highly resilient cracks and joint sealing system for expansion and connection joints.
Roka Seal PS is a polysulphide-based elastic sealant for horizontal and vertical expansion
joints. Roka Seal PS is suitable for hot and tropical climatic conditions.
Roka Seal PU is a single-component, polyurethane-based, elastomeric sealant designed for sealing expansion and construction joints, connecting joints between walls and windows, and window and door joints.
Roka Swell is a one-component polyurethane-based hydrophilic sealant that swells in contact with water to seal all types of construction joints and penetrations in concrete structures.
One area might get sunlight all day. Another might deal with oil, grease, or dampness. That’s why you can’t just use any product anywhere. We look at the surface, see what it goes through daily, and apply the right solution. Whether it’s for floors, rooftops, or walls, concrete sealants only work if they suit the surface.
If you’ve seen concrete flake, crack, or turn powdery that’s usually from water getting inside. And once that happens, repairs cost way more. Concrete sealants, when applied early, can stop that completely. Handle it once now, and you won’t be fixing cracks every few months.
Once it’s done, you won’t have to think about it much. It holds up through weather, heavy use, and time. No peeling, no weird maintenance. It just does the job quietly. That’s the beauty of using the right concrete sealants from the start.
