Joint stabilization – If you don't have sand in the joints, rain water or pool water will run between the brick paver joints, and wash out the base aggregate sand material your brick pavers float on, (usually a 1.5” – 2” sand base) making your brick pavers loose, wobbly, uneven, sunken in or even raised up in some ...
Polymeric sand is the most popular and useful filler used under brick pavers. It is a mixture of fine sand, adhesive and is most widely used in paver joints. Typically, polymeric sand lasts for up to 10 years. But if you use high-quality polymeric sand, it can last for approximately 15 years.

Vinegar is acidic and will eventually kill most broadleaf weeds, but the acid will kill the leaves before reaching the root system, and the weeds may grow back quickly. For longer-lasting removal, mix 1 cup of table salt with 1 gallon of vinegar. Salt dries out the weed's root system.
Initially, some water will seep into the joint sand for the first few weeks but soon silts and dust in the air will fill any voids and water will then shed off the paver surface just like any other pavement.
