Product Information

Our professional team of block paving experts is here to break down the jargon and highlight the information you need to make an informed decision.

Our dark granite stone dust is a strong choice for both wide and narrow joints between concrete tiles and natural paving stones.Keep your weeds safely at bay and fill your empty spaces with the No Grow Brush Paving Sand from Dansand. Dansand Top Lock ® requires a joint depth of minimum 40 mm to harden properly – preferably in the entire height of the paving stones. At the bottom of high-speed ferries and many other large ships are tonnes of silica sand delivered by us. Cool fact: Placing freshly laid eggs in a water glass solution seals the pores of the eggs against bacteria and gases, so it can be used to preserve eggs when refrigeration isn’t an option.

Extreme weather conditions can cause efflorescence in the joints and on the edges of the paving stones. Using a DANSAND® NO GROW™ filling material in your joints means waving goodbye not just to hard work – you can also wave goodbye to harmful chemicals. I would be concerned that conventional 4:1 sand / cement mix will crack like it has in the past and it will get to the state it is now, albeit it hasn't been touched or maintained for something like 10-20 years.This block paving filler prevents weed growth by simply drying out the seeds before they have a chance to germinate. I just jet washed my huge drive, next step is to kill the weeds and then I am looking to fill the huge gaps between the slabs.

Also, the lime and mineral content in the filling material may leave a whitish coating on the paving stones. Rain will eventually wash the efflorescence away, but normal traffic and/or cleaning may also remove it.There are essentially two types of weeds: Weeds that spread through a root network, and airborne weed seeds that settle in the joints.
