Paul Larson Concrete Warranty Information

* 1 YEAR WARRANTY - Top Surface Failure or Scaling. For a crack that has separated up or down more than 1/4'', which would cause a trip hazard.

*1 YEAR LIMITED WARRANTY - On a crack that does not follow a control joint or "random crack" and does not separate or cause a trip hazard. We will replace the cracked portion for cost of the concrete and half of the labor cost. We will pay for dumping, stone base, rebar, sealer and half the labor.

*LIFETIME NO CHARGE WARRANTY - On a Chert pop, most loads chert pops are not an issue, but if you happen to get a chert pop which typically shows up the first winter. We will drill out the rock and repair with the best permanent repair patch that we can find (color may vary).

*WHAT IS CHERT AND WHY IT OCCASIONALLY CAUSES A POP: Chert rock is a soft porous limestone vein that is evident in all of northern Illinois. Absorption of water and subsequent freezing can result in what are commonly called “pop-outs” in the concrete because of the chert particles fracturing and dislodging from the concrete surface as a result of the expansion and contraction that can occur during the freeze-thaw cycle. We proudly use Rogers Ready Mix who are known to be well below the IDOT limit of 2% of soft aggregate or chert in their mix design.

*CRACKS IN CONCRETE - All concrete flatwork projects larger than ten feet are expected and designed to to crack in control joints within hours of placement and most certainly within 28 days which is how long it takes concrete to fully cure. We meet or exceed recommendations of the Illinois ready mix concrete association.

A Few Things We Do To Minimize Random Cracks and Promote A Controlled Crack:

1. Install control joints in the wet cement every ten feet or less (no saw cut control joints, not only for looks but the cement can crack before it is dry enough to cut). 
2. Do not pour the concrete to wet which weakens the concrete and increases shrinkage cracks.
3. Add fiber mesh to every load to minimize shrinkage cracks and add flexural strength.
4. Install fiber rebar both directions to prevent concrete from excessive movement causing trip hazards (no wire mesh which will eventually rust and break causing a potential trip hazard). 

A Few Examples Of Cracks Caused By Things We Cannot Control:

1. Ground freeze/thaw causing movement. More movement is common if ground in surrounding area is not landscaped properly with correct water drainage.
2. Heavy trucks or equipment turning around on your driveway without you even knowing.
3. Minor earth tremors or earthquakes.
4. Blasting in quarries with explosives.

DO NOT USE SALT THAT IS NOT RECOMMENDED FOR FIRST YEAR CONCRETE, OR USE EXCESSIVE AMOUNTS.
