Dansand NO Grow Joint Filling Sand, Natural

Product Information

The ultimate goal is to AID water flow towards the house which has ACO drains around the edge to run the water away rather than have it spill into the gaps and into the ground around the house, missing the drains. Sweep the filling material into the joints using a soft broom. Sweep lengthwise and diagonally on the joints until they are completely filled. This allows for targeted protection only from unwanted plant life, with the surrounding flowers and bushes in your garden and around your paving installation completely free from environmentally unsafe chemicals or growth-inhibiting compounds. Problems The joint material must not be used in the joint directly against a plinth or other masonry. Use neutral joint filling sand here, as otherwise there is a risk of efflorescence or peeling

Sure, you may need to re-sand the joints every two years as the vibrations from cars or heavy footfall may loosen them over time, but with such a simple brush in application, you’ll have this job done in no time at all! Value for money The NO GROW mixture consists of washed and dried silica sand as well as nutrient-poor minerals with a high pH value. The high pH value causes weed seeds to dry out so that they cannot take root and germinate – in a completely natural way. The minerals dissolve slowly and can only be washed out after 10 years of rain. With the correct use of DANSAND ® joint filling sand, you get a great result that lasts for many years.

Environmentally friendly

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. I am after advice on what to fill it with, keeping in mind the following: To avoid weeds and displacements in the paving, the joint must always be filled to the full height of the joint edge and be completely free of soil and other organic material. The paving is cleaned with a stiff broom and the joints are refilled as needed. Moss and algae can be removed by suitable means. Extreme weather conditions can cause white deposits (efflorescence) in the joints and on the edges of the paving stones. However, they are usually washed off at the next rain shower. The deposits can also be removed by regular cleaning of the stones. Try to save any left over sand for future use in areas of paving you may have missed or is lost due to wind and rain. we are sorry to learn that you had a bad experience using DANSAND® NO GROW™.
