Brick Paving Maintenance

Brick Paving is nearly maintenance free in Minneapolis,Mn.  Unlike asphalt you will not need to seal brick pavers, although you can.  Asphalt is bituminous and will dry out and crumble if it is not maintained.  Concrete brick pavers are naturally porous and there are sealants available that can be a good idea if you are worried about stains from a vehicle leaking oil on a Brick Driveway or maybe a grill dripping grease on a Brick Patio.  There are sealants available that can actually enhance the appearance by giving the bricks a “wet look” while also protecting from staining.  Some of our customers in Shakopee, Mn prefer the rich colors achieved through the use of such sealants.   Sealants will need to be reapplied every other year or two depending on the quality of the sealant.  Premier Patio and Landscape endorses the use of sealants such as “Block Paving Pro”, “Surebond”, and “TechniSeal”.  Please follow the manufacturers recommendations.  Most sealants shouldn’t be applied within the first year of brick installation due to efflorescence.  Efflorescence is a natural salt found in all concrete products and can sometimes bee seen on the surface.  Efflorescence will not affect the performance of the paved surface but a sealant can highlight or even seal in that appearance.  It is best to wait one year after installation to apply a sealant to a concrete paved surface.

Occasionally in Minnetonka,Mn water run-off from a roof without gutters or from a downspout directed towards a Brick Walkway will cause sand to be washed away from in-between the bricks.  The loss of sand from rain water can cause bricks to settle over time.  If you determine there is the potential for this type of water damage you may want to consider using a Polymeric Sand as opposed to the standard coarse sand.  Polymeric sand, after swept into the joints between the bricks and dampened, will harden enough to stay in place while remaining flexible enough to allow movement during stresses from freeze-thaw cycles.  Polymeric sand will aide in shedding water across the surface and limit water that would normally be absorbed into the paved surface.  Premier Patio and Landscape does not recommend applying polymeric sand on Brick paved surfaces that are shaded from the sun.  Polymeric sand is a relatively new product, but we have noticed that shade will tend to cause the growth of moss in joints filled with polymeric sand.  If you are worried about sand washing out and your paved surface is shaded from the sun there are a few sealants that offer joint stabilization along with stain protection.  On the other hand if your brick paved surface is exposed to direct sunlight for most of the day there is the risk of fading.  Sealants, especially the enhancing types such as “wet look”, will offer much protection against washout and fading.

Premier Patio and Landscape recommends sweeping a small amount of coarse sand across the brick paved surface annually as regular maintenance to help account for sand that has been lost due to the elements such as rain and wind.  This does not apply to brick surfaces with polymeric sand.
