About this deal

However, since these areas are free from rain, excess salts and minerals from the filling material may migrate to the surface of the joints, causing white efflorescence.

As it’s our reputation on the line if we get these things wrong, you can rest assured that our recommendations have taken a lot of thought!There are essentially two types of weeds: Weeds that spread through a root network, and airborne weed seeds that settle in the joints.

If the joint is too narrow, it will not harden sufficiently due to too little material present in the joint.Dansand® joint filler is made entirely from silica sand, natural high pH minerals and a natural binding agent.

To prevent existing weeds from growing, all weeds – including weed roots – must be removed before refilling the joints.The dust gives a fine result to match paving stones with particular characteristics such as cobblestones – and leaves very little dust. Mix the filling material with a shovel in a mason tub or wheelbarrow so that the mineral additives are mixed well with the silica sand.

With a simple brush in application, this jointing sand produces fully permeable joints in block paved driveways with no premixing or additional chemicals to worry about; just a little moisture will create solid joints! Je regrette cet achat que j'ai effectué pour faire le remplissage des rigoles sur les trottoirs extérieurs et limiter la repousse des mauvaises herbes. Dansand is one of the world’s leading specialists in the field of jointing sands, with their refined and kiln-dried silica sands being a popular choice in block paving projects across the globe. Next, you can use a high-pressure cleaner, but be careful not to damage the paving stones or the substrate. It’s simple to use and effective at preventing weed growth for up to 10 years, allowing paved areas to stay attractive for longer.If you do use it then consider using a drive/patio sealant over the whole area which is my next plan. The only positive is that a 1cm wide joint has stayed fairly full and the sand there seems surprisingly resilient to prodding. As reported throughout 2023, the horticultural sector faced record-breaking weather extremes, from the driest February in 30 years to the hottest June on record.
