Our Warranty

The most common question, and most common misconception about concrete is, “Will it crack?”. The answer is simple… PROBABLY YES, but don’t be scared. Read on to learn all about cracks and how the Johnny’s Concrete warranty works for you.

Cracks are a natural consequence of exposure to the elements, and the curing process. There is no way to prevent or predict when and where a concrete slab may crack, and there is no minimum grace period or time limitation, a crack may appear within a day of a slab hardening, or after decades of undisturbed, unblemised surface. The trick is not in stopping the cracks, it’s about minimizing their impact.


  • begins on a firm, compacted base
  • has consistent and correctly placed and / or anchored steel re-enforcement abundantly and appropriately gauged for the intended use
  • is poured with concrete mixed to the correct strength for the intended use
  • has enough depth of concrete to support the intended use

A crack is a surface blemish only, it does not compromise the originally intended function, shape, or grade of the slab. Cracks are unavoidable and are not covered by our warranty policy, which is consistent with provincial guidelines set out by construction organizations in Alberta such as the A.R.M.C.A. (Alberta Ready Mix Concrete Association) and the Alberta New Home Warranty Program Workmanship and Material Reference Guide.

A break is identified by a crack that has either opened into a significant void of 1/4 inch or more, or that is accompanied by either vertical or horizontal shifting. If natural wear and tear and exposure is able to exploit a crack into a break, that is a symptom of a defective product.


Your beautiful new concrete can last for your entire lifetime with proper care, but it is NOT indestructable  THERE ARE SOME LIMITATIONS in our warranty that you should read. Making the best choices NOW is a critical component of having a maintenance-free job that you will be proud of  forever.

Choose the right finish for the job. Things to consider:

  • Purpose: is this intended to be a driveway or a garage pad, a sidewalk, or a patio – will it be covered or open – is it used  seasonally or year round? Slabs that are intended for cars to drive over and park on like driveways for example, have a very different use than one that is poured to offer a comfortable recreational experience such as the inside of a sunroom patio – and therefore not all options may be the best idea for your needs. Our consultants will help steer you to what the smart choice is for you, and explain why.
  • Safety: when does a slope become a dangerous slip n’ slide? How tall can a proper step riser get to be comfortably navigated, and how short can it go before it becomes a tripping hazard? We know the answers to all these questions and more.
  • Durability: Not all finish types are equal, and not all ground conditions are right for just one type of concrete. For example, if you are parking a winter-driven vehicle on the wrong type of surface, you could wreck your concrete in as little as 3 years instead of enjoying it for over 30 years. Our experts will present you with the BEST options.
  • Texture: A front sidewalk should have grip, a poolside patio should be comfortable in bare feet, you would want a garage floor that you can comfortably sweep with a dust broom. The type of finishing on your job should take into consideration what activities will take place there.
  • Beauty: will your new concrete compliment or clash with the other surroundings? We are 3rd generation experts and creative artists.
  • Budget: there are many opportunities to make trade-offs that can bring a job in line with your budget, but nobody would choose a  compromise that would ultimately cost them more in the long run. We will help you cut costs in areas where it makes sense, and warn steer you clear of places where it doesn’t.

Consider the environment:

  • On the day of the pour: we’ve down our homework. We know the climate forecast for high, and low temperatures on your day and what time to expect them. We have also considered other factors like direct sun or cloud cover, shady spots, precipitation, wind… the overall size of the pour, the number of finishers on the job. We will know how to order your concrete with the proper slump viscosity or additive adjustments required for a successful pour and a forever finish.
  • During the next 28 days of curing: even though it may seem hard on the surface after only 24 hours, you concrete continues to cure for 28 full days after it is set in place and there are definitely some conditions to avoid happens during this period to ensure a full-strength cure.
  • Foreign Substances: Alberta’s freeze and thaw cycle is already a challenge for any type of building material to withstand, but additional factors like ice-melters, road salt, and unapproved DIY products pose a barrage of extra dangers that will void a warranty. Let us help you make the best choices to protect yourself against these risks.

Plan for the future:

  • Maybe you are planning an addition in the future that will impact your current design, or have you considered adding 6 extra inches of sidewalk width to accommodate a wheelchair in someone’s future? How about when that fence needs replacing, have you left enough room to dig the post holes along your property line? None of us have a crystal ball, but short-sighted decisions create a lot of mistakes that may not have seemed predictable to you in the moment, but they are common to us. We’ve picked up a lot of hints and tricks to consider that will make your life easier down the road.
