Paver Maintenance

You invest a great deal of money into your hard surfaces, remember to keep your surfaces looking new for years to come with preventative maintenance. Neglecting proper maintenance, your pavers will begin to fail due to multiple factors: natural erosion, weed growth and insects. Pavers are installed with a joint compound that is swept in the cracks. Joint sand is the final key to the interlocking pavement process. As long as the base remains intact, your pavers will maintain their integrity. Erosion can occur when constant water flow starts to wash out the sand from in between the cracks of the pavers; if this occurs the base can start to wash out and your pavers will begin to fail. Once the joint compound begins to fail it leaves the pavers vulnerable, and windblown soil can infiltrate the cracks of the pavers along with weed seeds. As the weeds start to grow the roots will start to compromise the base, forcing the pavers to shift.  The plants roots will start to allow water into the base, and during the winter this will start to accelerate the erosion process. Insects, especially ants, can wreak havoc on your paver base;  they can undermine your base from below and can also make your pavers look unsightly with all of those little mounds. Ants are extremely difficult to get rid of and chemical application may be necessary to remove them.

Joint compound lasts about 3 seasons and then the compound inside the sand will start to break down giving way to natural erosion. Once erosion and weeds start to grow within the cracks they will need to be removed, this is where power washing comes into play. Power washing your pavers every three seasons will remove any debris that may have blown in along with any organic matter, allowing room for new joint compound. Power washing and resanding your pavers every three seasons will not only keep the integrity of your pavers intact, but will give your paver space looking new and clean.

Exposed aggregate concrete should be maintained and sealed every three seasons to not only keep that shiny glossy look, but also to keep the stone finish from chipping and wearing prematurely.
