Brick Paver Patio Repairs : Not So Easy

We are working hard on a brick paver patio repair in Ann Arbor. This paver patio is a basement walkout brick patio that has been neglected for years.  It has drastically sunk and the drain is non functional because the brick pavers are almost sunk a foot below.  The new homeowner just purchased this property and the paver patio failed the home inspection.

Often when I quote for brick paver repairs, homeowners believe it is an easy process to reinstall the brick pavers since they are already there.  This is far from the truth. The first step is to lift up, stack, and carry the brick pavers to a staging area. Often this is a messy and back  breaking job. Todays job was down 6 stairs and the paving stones had to be carried up.

The old brick pavers are staged in an area until the base material is properly prepped for reinstallation.  Aside from digging, the prepping steps of interlocking pavers is performed : compaction, screeding, cutting, sanding, edge restraint installation, etc..


One of the most time consuming steps in brick paver repair is the cleaning of the pavers prior to reinstalling.  The brick pavers need to be powerwashed on all sides or scraped as in this picture. Dirt, sand, or old paver sealer sticks mainly to the sides and has to be removed prior to relaying pavers. Homeowners never realize this step takes place. For the brick paver contractor, it would be easier to use new pavers at this stage. Of course, that would be an added expense for the homeowner and this cost is offset by our nominal charge.



Once the paving stones are cleaned and ready for re-installation, the brick paver stacks are then carried back to the working area and carefully placed for relaying. Today's job in Ann Arbor was grueling because we had to carry the stacks down steps to the paver patio area.  Time to take some Motrin and lay in the jacuzzi tub!

Brick Paver Repair or Winter Frost Effect

The Winter frost in Michigan is going to begin to thaw in March. Like most freeze thaw cycles, the devastating effects will push all pavements, even brick pavers, to their extremes. Spring is just around the corner and most homeowners will begin to come out of hibernation and stretch their arms & legs. One of the first thing homeowners do is inspect their paver patios, walks, or drives.

The beauty of interlocking pavers is their capability to expand from winter frost with minimal or no damge. The paver joints absorb the effects of frost and the high density & low absorption rate of the brick pavers keep them from cracking.  But when you are dealing with mother earth, there are no guarantees that brick repairs will not be needed from shifting or heaving.

I always receive calls from frantic customers in pre-Spring weeks that their brick patio has a huge heave or raised area.  Good News! this is interlocking brick pavers at work! After the winter frost works its way out, your brick pavers will reset. No cracks, warps, or expensive repair costs.  As the temps float over and below the freezing mark, you can literally watch your paver patio move like a waterbed mattress.

Pavers that are raised or heaved, will go down. Pavers that are down, most likely will not come up. So, you may now have some type of brick paver repair that will need to be addressed. Do not confuse that brick areas are low because other brick areas are raised.  It is not unusual in Michigan during late March to early April to see your brick patio look like pizza dough be tossed at a pizzeria.  It should all level off when it gets warm and dry and you can enjoy this one free topping.

Once the Spring weather gets warmer & dryer, do not forget the most important brick paver maintenance requirement .... sweeping joint sand in the paver joints! As mentioned in earlier posts, this will deter lateral paver shifting, base erosion, and weed growth.  So, before you call your brick paver contractor for patio repair work, make sure the winter frost has completely thawed.

Brick Pavers Installation : Step 2 Prep & Excavation

After doing some PLANNING of your brick paver project, it is time to PREP & EXCAVATE the area to install your brick paver patio. Mark out the location of your brick paver patio, walkway, or driveway by using marking paint or use the family garden hose to outline your paver project. It is always a good idea to contact MISS DIG in your area to have all utilities, phone, & cable marked before excavating for your paving stone patio.

The tools that will be required for PREPPING your interlocking brick pavers are simple at this step. You will need a wheel barrel, pointed shovel, rake, and some sweat equity. Always remove any sod (grass), mulch, stone, or existing concrete where you will be installing your patio stones. You can strip your sod or concrete out if your paver patio is not that big, but often it is best to rent a power sod cutter or air jack to help in removals. No sense physically burning yourself out in the early stages of this project. Once the area for your brick pavers is prepped, it is time to excavate the area for base material.


EXCAVATING for brick pavers is usually the hardest physical part of any paver project. Most homeowners do not have a skidsteer or tractor to dig out the area to be excavated for a patio, walkway, or paver driveway. This step will require some sweat equity and is important not to be skimped on. MAKE SURE YOU EXCAVATE DEEP ENOUGH TO ALLOW FOR THE PROPER BASE DEPTH to help insure long term performance of your brick pavers. In the earlier posted PLANNING step 1 I detailed how to set your heights. Now, from the top of your brick paver height, you want to excavate down @9" . I determine this measurement from 2.75" of paver thickness, 1" of bedding (screed) course, and average 5" of gravel base. For a brick paver patio or brick paver walkway, 4-5" of gravel base is sufficient if the soil drains well. For brick paver driveways, you will excavate down @13" from the top paver height. Basically you are doubling the gravel base thickness for normal driveway applications. If you experience clay soils, I would add 2-3" of gravel base thickness for patios & walks, and add 4-5" for driveways. It is important to excavate brick paver areas @4" wider along all outside edges so you have base to install the edge restraint on and also give yourself some flexibility in the final layout when installing the brick pavers.

Once these physically challenging steps of PREPPING & EXCAVATING for brick pavers is complete, you will begin to enjoy the "fruits of your labor" as the paver patio begins to evolve. Check back soon for Step 3 : Base Material for Brick Pavers.
