The Detail
Everything you'd ask a specialist on the doorstep.
Materials, methods, variations, and the small decisions that separate a 20-year driveway from a five-year one.

Pressure washing, the right PSI
Block paving cleans best at 2,000–2,500 PSI with a rotating turbo nozzle. Resin bound needs much lower pressure (1,200–1,500 PSI) and a fan jet, too high and you strip the surface aggregate out of the binder. Natural stone (sandstone, limestone) needs a soft-wash approach with biocide and lower pressure to avoid surface etching. One-size-fits-all wash kills surfaces, we set the kit for the surface.
Joint re-sanding versus polymeric upgrade
Standard kiln-dried sand is the original block paving jointing material and remains the cheapest option. Polymeric jointing compound, sand impregnated with a polymer binder, costs more, takes longer to install, and stays in the joints for 10+ years with no weed pressure. For driveways being restored for the long term, polymeric is the better investment.
Sealing, what it does and doesn't do
A driveway sealer protects against staining, slows joint sand erosion, deepens colour, and adds a satin or matt sheen. It doesn't make a driveway maintenance-free, doesn't fix structural problems, and needs reapplication every 3–5 years. On premium-grade block paving and resin, sealing is optional but adds visible value; on cheap concrete blocks, it's not worth the spend.
Weed control, surface versus root
Surface weed killers (glyphosate, acetic acid) kill the leaves but leave the root system to re-grow. Long-term joint weed control needs root-deep biocide treatment plus joint re-sanding to remove the growing medium. Polymeric jointing compound is effectively weed-proof for the first 8–10 years.
When restoration won't fix it
We won't sell you a clean if your driveway needs a re-lay. If the sub-base has failed, the edges have collapsed or the surface is structurally compromised, restoration is throwing money at a problem that needs proper repair. We'll inspect honestly and tell you which one your driveway needs.
