Brick Pavers Dirty Little Secret : Paver Joints

Paver Joints are the most important part of your Brick Pavers Installation

It amazes me every day when I am doing estimates on brick paver repair & restorations that homeowners had no idea they needed to keep paver joints filled with paver joint sand. More than the paving stones themselves, paver joints have the most important function of interlocking brick pavers.  Here are paver joints dirty little secrets.

Paver joints are the whole purpose for brick paver "lock-up".  Paver joints for interlocking paving stones allow for the bedding coarse to shoot up and lock the paving stones together during plate compaction.  As the plate compactor vibrates across several paving stones at once, the paving stones depress and force the bedding coarse sand or slag to "jet up" into the paver joints and lock up the paving stones laterally.


The next important step is to sweep in proper paver joint sand to completely fill the paver joints. Full paver joints will help prevent the paving stones from loosening, shifting, and unnecessarily settle from erosion.  What is so perplexing is that sweeping in paver joint sand is so easy and effortless and most homeowners will not perform this basic paver maintenance requirement. In Ann Arbor, sweeping is usually necessary each Spring as the Winter frost, snow & ice, and Spring rains wash away the top of the paver joints.  The upgraded use of Polymeric Sand will greatly reduce the amount of paver joint sweeping due to the strength of this bonding sand. Here are some paver repair projects that we used Polymeric Sand to help avoid future repairs.

Keeping paver joints filled with paver joint sand is important to help keep weed seeds from establishing .  If the joints are not filled with sand, this presents a perfect setting for weed seeds or dirt to settle in and promote growth.  Dirt, weeds, and grass inhibit the proper flow of water through the joints and does not allow for application of a paver sealant.


 Paver joints absorb the winter frost effects of heaving so the paving stones do not crack, grind, or chip. While protecting the structural integrity of interlocking pavers, paver joints will lose joint sand over time. Sweeping in new paver joint sand is a small price to pay for protecting the beauty, appearance, and performance of your brick paver patios,walkways,driveways, and more.

In frost states like Michigan, it is highly recommended not to fill the joints of high density concrete pavers with mortar.  I see many outdoor applications using mortared interlocking paving stones that will some day fail.  Mortared paver joints in a frost State does not stand up to the flexible heaving of base laid pavers. The other important factor is that high density concrete pavers are much stronger than mortar. As the paving stones expand slightly they will crack or break up the mortared joints. This will become and unsightly and costly future repair.

After years of neglect, paver patios without paver joint sand may require us to completely  re-sweep in new joint sand and re-compact the whole patio with a plate compactor. This will help re-lock the paving stones into the bedding coarse. We will then finish off the top of the paver joints with an approved joint sand.

Most homeowners believe that you must protect the paving stones with a sealer which is not true. Sealing brick pavers is an option and is mainly for aesthetic purposes.  The best way to protect your interlocking pavers is to keep the joints filled with paver joint sand. This is a simple and very cheap way to avoid costly and unnecessary paver repairs.

2011 will be a good year for Brick Pavers in Ann Arbor

Paver Patio Installations, Repair, Cleaning, and Sealing is on the rise!

As the economy in Ann Arbor, Saline, Canton, and Southeast Michigan improves slightly in 2011, homeowners are now reconsidering their brick paver patios & walkway needs. Paver Patios and walks have dominated the Outdoor Living spaces market for the last 30 years but has suffered a tremendous downturn due to the economic turmoil the past few years.

As a hard working brick paver specialist and contractor the past 28 years, I noticed the pendulum starting to swing back to more brick paver interest and needs during 2010.  I expect 2011 to make huge strides in the installation, repair & restoration, cleaning, sealing, and maintenance of interlocking pavers and modular retaining walls.

All service areas for paving stones are on the rise and good brick paver contractors are offering the spectrum of services that homeowners need.  Below are the reasons I am so optimistic about the 2011 brick paver season.

Installations:

As the economy has slightly ticked up, so has new home building. Though it is minimal, new home building has began to re-emerge.  Up until about 2006, 50% of my brick paver company revenues came from "new" home installations. In 2008, it fell to less than 10% of my total revenues.

Brick paver contractors lived and died by the new home construction sword if they were not diversified with offering "all" brick pavers services.  New home paver installations are the most profitable projects for brick paving contractors and this slow insurgence of new home building will help make this concrete paver industry more attractive.

Repairs & Restoration: 

The flip coin of homeowners not being able to sell their homes or build new ones was the insurgence for the need of "existing" brick paver patio, walkway, driveway, and porch repair. Homeowners quickly realized they were staying put and there was an immediate need for their brick pavers and retaining walls to be repaired and restored.

It is easy for homeowners to neglect their paver patios since it was not a financial necessity.  But as homeowners came to the conclusion that they were remaining in their current homes for years to come, they focused on home improvements.  With a little touch-up and re-focused attention too, paver patios could once again be an attractive and functional family outdoor living space. I predict that my paver repair & restoration projects in 2011 will double due to the emphasis by homeowners to improve what they currently have.

Cleaning, Sanding, and Sealing:

Good brick paving contractors will educate their homeowners to the benefits of touch-up repairs, cleaning, sanding, and sealing (optional) of paving stones.  In Ann Arbor, there has been a tremendous interest in these brick pavers services.  Interlocking brick pavers and retaining wall maintenance is now in the forefront.

With new and improved products for paving stones hitting the market each year, the needs for these opportunities to improve the appearance of paver patios has come to the attention of homeowners. From removing moss, efflorescence, and rust stains to polymeric sand to varying sealer appearances, paving stones products are revitalizing the attention too paver patios, walkways, driveways, and paver porch maintenance.

In conclusion, there is a resurgence in the attention for interlocking brick pavers and modular retaining walls services throughout Michigan as the economic uncertainty is stabilizing. Homeowners are reinvesting in their current homes while new home builidng begins to reappear. Capitalizing on these diverse services of paving stones will improve profits during 2011 for any good brick paver contractor who pays attention to this opportunity.
