Polyurethane concrete raising is a fantastic alternative to traditional mudjacking or replacing your concrete. There are numerous advantages of using polyurethane over traditional mudjacking, and often the process will save you over 50% of the cost of replacement!
When a homeowner contacts us for a free estimate, we often find ourselves consulting them whether they should level and repair their concrete, or possibly even replace it. Quite often they are pleasantly surprised when they discover they can have perfectly aligned concrete again, in a matter of a few hours or even minutes, saving them time and money while having the ability to use it the same day.
Typical questions that homeowners ask are often around the timing of when the work should be completed. It is important to remember that maintenance is always far less expensive than repair or replacement. Think of changing the oil in your car’s engine; an oil change is affordable, repairs can be costly, but replacement is extremely expensive, concrete is no different. If you begin to notice a small trip hazard why wait until someone falls or until the crack is so big that it cannot be repaired? Another example of maintenance is when concrete pads, driveways or sidewalks start to tip towards the foundation, why wait until water starts to seep into your basement? Often when water starts to penetrate a foundation it is not noticed until a musty odour is present, the floor is damp, or in some cases, mould appears. If you notice water “pooling” beside your foundation, you should correct the slope of the concrete as soon as possible.
“Why did my concrete settle”? This is another very common question. There are a few main reasons; poor compaction when the home was originally built. If the soil was wet or frozen when the foundation was backfilled the “chunks” of soil would be much larger than if the home was backfilled with sand. In wetter years these “chunks” may not break down but in drier years trees and vegetation can dry out the “chunks” causing settling where the foundation was originally excavated. Once this occurs, the soil settles, and voids are created below the concrete reducing the slabs support. There are many other reasons for concrete to settle such as the size of the steel dowels that are used. A dowel is usually a short piece of rebar that is spaced approx. 16 - 24”. A hole is drilled into the foundation; the dowel is then inserted into the hole while the other end is then tied to the rebar that is in the concrete slab. Often you will notice when a slab settles against a foundation small rusty pieces of metal are present, these are usually the dowels. If the holes for these dowels were not drilled far enough into the foundation, were too big in diameter or at the proper angle they will simply pull out of the foundation. Also, these dowels can be too small in diameter for the weight they support or they simply rusted through causing your concrete slab to fall.
In conclusion, there are many benefits to having Eco Concrete provide you with an estimate, often we point out ways of saving the homeowner thousands of dollars either presently or in the future.
