How to fix a crack in a concrete foundation
For start , let me tell you that the majority of concrete foundation have cracks .
Cracks in concrete apear for many different reason but the most common reason is ground settleling under the weight of the house built eitheir on improper types of ground and miscalculation of the bearing capacity of the type of soil built on.
Having an engineer perform a ground test before construction is a wise thing to do.
Not doing so to avoid spending the money may cost you way more.
Never the less with the best precautions cracks will happend.
What to do if this happend and is it recommended to fix it ?
It is never a good idea to let things go and if not taken care of , in long ter mit might bring you bigger problem.
Not fixing it might mean water infiltration, insects, mold and mildew.
Longer you wait worst it will get.
So, how it works ?
The process consist in filling the crack with a waterproof material under pressure
( polyurethane or epoxy) and depending on the width of the crack, install steel belts for
Basicaly you have to get to the craked foundation and expose it.
There is two way to do it with pros a con.
From inside out, no digging :
To have access to the crack sometime it means to remove the wall finish if covered ( drywall, studs etc…)
The process is to inject material inside to outside.
– No need to excavate
– Less invasive
– Cost less
– Quick fix
– Sometime the best thing to do when impossible to dig because of ouside structure
– Less efficient because you are working against hydrostatic pressure and even when well done will not last in time
– Contrary to fixing with digging , you can’t put an exterior membrane as double protection
– Not bullet proof and will need to be redone in a few years
From outside with excavation :
In order to expose the crack from outside, excavation is needed.
The injection is done from outside toward inside.
The inside crack is covered with hydraulic cement when accessable to prevent material spill inside.
The installation is doubled with a membrane covering the crack making the repair more efficient .
– Long term repair with double protection
– Block all access to water infiltration by covering a wider area around the crack
– Allow you to install steel belt reinforcemnt under ground
– Allow you to check the efficiency of the french drain or find out if you have one
– Damage the landscape
– Cost more
Both approaches in crack repair have its place depending of the situation but in most cases it is far better to make the repair from the outside unless impossible.
