On many of my brick paver repair estimates, I am asked to give pricing options for the repairs of their brick paver patio, sidewalk, driveway, porches, steps, or retaining walls. Usually these pricing options include doing the paver repairs using the "band aid" approach or the total reinstalling of the interlocking brick paver or modular retaining wall project.
The dilemma for the homeowner is to decide whether to accept the "band aid" approach which is usually considerably cheaper, or biting the bullet and accepting the commitment to properly reinstall the paver project. Because of the price disparity of these approaches, their are considerable questions and angst by the customers.
The "band aid" approach is referred to as the "cosmetic" approach. The homeowner wants me to just "make it look better" at a minimal cost. I tell customers that the "band aid" approach is a short term repair method that will improve the appearance but not necessarily the long term performance of their brick paver installation. I usually have this request from people that are going to be selling their homes in the near future or if a pressing safety issue exists. Basically this approach is to "cosmetically" repair the paving stones or landscape walls without addressing the sub base below or the major issues that may result in future failures. I will only give a 90 day warranty on these type of repairs. I believe that this brick paver repair approach is more suited for minor settling or heaves from frost. The "band aid" approach should be used early on to correct any minor or small brick repairs that become visible. Too often customers let minor settling or heaving of pavers go unattended which results in major repairs & costs.
The other approach to brick paver repairs is to completely reinstall the brick pavers or modular retaining walls from the bottom up. This will require not only lifting up the paving stones or landscape blocks but completely removing and reinstalling the base & bedding course. Obviously the cost of this type of brick repair far exceeds the "band aid" approach. The customer does save the product costs which is the major advantage of interlocking brick pavers and modular retaining walls. I will usually warranty any total reinstallation project for 1-2years since I am completely reinstalling to my specifications which meet or exceed any brick paver manufacturer's, such as, Unilock or Belgard, recommended installation specs.
It is very disheartening to me for customer's to pay $1,000's of brick paver repairs after making a considerable investment in their paver patio, sidewalk, or driveway. Brick Pavers are NOT no maintenance. Paving stones & landscape blocks require some minor touch up maintenance to keep them beautiful and functional. It is much better to pay "band aid" prices of $100-$200 each couple of years with brick paver maintenance then to wait 5 years and let the pavers or walls collapse and cost $1000's to repair.

Top Reason for Brick Paver Repairs
Yesterday I met with Al Martin, a UNILOCK sales representative for North America's largest brick paver manufacturer. We were discussing the challenges that the climate in southeast Michigan presents for interlocking brick pavers and modular retaining walls.
We both agree that our frequent "freeze thaw cycles" , the cycle of the ground freezing and thawing during the winter months, creates a lot of paving damage. It has been no secrete that the roads & highways in the Detroit area exhibit these damages like no other metropolitan area in the country, with Chicago a close second. I would like to comment on the effects of sub grade frost on pavements.
People enjoy the warmer weather here in Michigan during winter month's, but like most good things, there is always a price. When the ground freezes, water or moisture does not trickle down through the water table. Typically, in the Detroit area the average frozen ground depth is 3 feet. This is the reason footings for deck posts or masonry walls must be a minimum of 3.5 feet so the frost does not get below. When the top of this frozen ground starts to "thaw" due to warm weather, it becomes mushy & permeable. The soil below brick pavers, concrete, and asphalt becomes unstable and falters from loads (traffic) and voids in the subsoil. To add more salt (no pun intended) to the wound, it refreezes and traps more moisture between the frozen ground below and the surface. This freeze thaw cycle creates tremendous stress on any pavement by heaving and contracting.
It is not unusual for the Detroit and Chicago areas to experience over 30 freeze thaw cycles during the winter months (Dec thru Mar). This is probably the equivalent of 5 winter frosts versus 1 for a northern city like Minnesota. Many municipalities try to reduce the damaging effects of frost thawing by imposing "Frost Laws". These laws typically reduce the weight allowed by trucks to haul by 50%.
This background leads us to the the conversation I had with Al Martin on brick pavers & retaining walls. It is obvious why UNILOCK locates most of its brick paver manufacturing plants in Chicago, Detroit, Cleveland, New York, Ontario Canada, Toronto, etc.. . These cities fall in what I call the Frost Belt. Interlocking Brick Pavers and Modular Retaining Walls are the most economical and functional pavement for the "frost belt" over time. Repairs of brick pavers is much more economical than repairs of stamped concrete or asphalt. Over 60 years of paving stone experience & feedback has proved this throughout Europe, Australia, and North America.
Many of my clients blame their brick paver repairs on poor installation and this is not always true. Often I do see brick paver patios, sidewalks, and driveways that were poorly designed and installed. The first thing I point out to them is how many times in the last 15 years did the County or State redo that stretch of highway nearby. Usually, it has been redone twice so that is 3 different pavements, sometimes 3ft thick of concrete, that have been totally removed and replaced on average 5-6 years.
Brick pavers and retaining walls that are properly monitored and maintained will out perform any wood deck, stamped concrete or ashalt pavement. Whether you perform brick paver maintenance yourself or use a professional, you can enjoy the financial and aesthic value of paving stones for a lifetime!
