Before filling your joints with Dansand® joint filler, be sure to remove all existing weeds and their root network.

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! However, we recommend a covered storage location, as the plastic foil will not withstand heavy rain. Paving stones must be laid on a sustainable gravel and sand layer in accordance with current standards for paving work.

With over 15 years of professional experience installing block paved drives, patios and footpaths, you’d better believe that our team has tried their fair share of jointing compounds. This unique composition creates a desert like and weed inhibiting condition in grooves making it difficult for weeds to take hold due to natural high PH value.

This membrane is resistant to wind and weather and makes it impossible for weed seeds to penetrate into the joint. I am very disappointed with Dansand,I followed instructions to the letter and now I have more weeds and moss than ever.IE 88957 with it's Registered Office: Grafton Group plc, Heron House, Corrig Road, Sandyford Business Park, Dublin 18, D18 Y2X6. I know the best case is to re-lay them all on a better base and/or level the entire drive so its flat but this isn't going to happen anytime soon! Joints should always be filled to the top, so remember to top up the joints from time to time and to keep the paving surface free from dirt and leaves.

Since the minerals are designed to inhibit weed growth for as long as possible, the efflorescence will take a long time to disappear. This means that the plaster may absorb salts from the filling sand, leading to efflorescence which cannot be washed off. Reliability, weed prevention, durability and ease of use are the key things we look for when jointing block paving.

You can minimise the formation of moss and algae by ensuring that the joints are always filled to the top with Dansand joint filling sand.
