Block paving offers a durable, stylish finish for driveways and patios, but without proper care, it can suffer from a frustrating issue: block paving dipping. Uneven surfaces, pooling water, and structural instability often stem from paving movement, particularly in high-traffic or poorly drained areas. Fortunately, Resiblock provides a proven solution to prevent block paving dipping and ensure long-term surface integrity.

Prevent Block Paving Dipping with Resiblock

What is Block Paving Dipping?

Block paving dipping refers to the subsidence or sinking of individual block pavers, creating low points or depressions in an otherwise level surface. This is usually caused by:

  • Joint sand erosion from rain or pressure washing
  • Lack of joint stabilisation
  • Poor sub-base compaction
  • Heavy loads or traffic stress

Left unaddressed, this can lead to significant surface degradation, safety hazards, and costly repairs.

How Resiblock Prevents Block Paving Dipping

Resiblock is a world-leading range of block paving sealers and joint stabilisers specifically engineered to protect, stabilise, and extend the life of paved surfaces. Here's how it works to prevent dipping:

1. Joint Stabilisation

    Resiblock products like Resiblock Block Paving Sealer and Resiblock Trade penetrate jointing sand and chemically bind the particles together. This forms a solid yet flexible joint, preventing the sand from being washed out while still allowing for slight expansion and contraction.

      Benefits:

        • No more sand loss from rain or jet washing
        • Stronger, more resilient joint structure
        • Maintains consistent surface level under load

          2. Water Ingress Prevention

            Block paving dipping often begins with moisture infiltration, which weakens the bedding layer. Resiblock sealers form a protective film over the pavers, reducing water ingress and protecting the sub-base from erosion or freeze-thaw damage.

              Benefits:

                • Reduced water penetration
                • Prevention of frost heave in colder months
                • Long-term surface stability

                3. Surface Protection from Traffic & Weather

                Heavy vehicles and constant foot traffic can disturb the jointing sand and compromise the bedding layer. Resiblock enhances the load-bearing capability of the paving by locking the system together, helping resist movement under pressure.

                Benefits:

                • Improved load resistance
                • Ideal for commercial driveways, public walkways, patios
                • Minimises long-term repair costs

                        Application Process for Best Results

                        To prevent block paving dipping effectively, follow this Resiblock application process:

                        1
                        Clean the surface thoroughly to remove moss, dirt, and old jointing material.
                        2
                        Re-sand joints using kiln-dried sand.
                        3
                        Apply Resiblock evenly across the surface using a roller or sprayer.
                        4
                        Allow to cure fully (usually 24 hours depending on product and conditions).

                        Pro tip: Always apply on a dry day and follow the specific product instructions for your chosen Resiblock sealer.
