Foundation Wall Cracks in Evans City PA
Do you have foundation wall cracks? There are many methods available today to repair these cracks. The method applied to the cracks in your foundation wall will depend on your contractor and circumstances. Therefore, it is wise to learn about the different methods and determine which you would like to invest in.
- Caulk repair
This is an inexpensive method for crack repair that many homeowners turn to in order to hide the appearance of cracks. A caulk seal is used to plug the crack. Sealing cracks is quick and easy. When done properly, it is hard to know that there was a crack in the wall in the first place.
The problem with this method of crack repair is that it is only skin deep. These seals are only effective while cracks are not leaking. They are prone to efflorescence when moisture begins to seep through. Water pressure can also force the caulk seal to peel off. These seals last between 6 to 12 months.
- Hydraulic cement
Hydraulic cement is sometimes used to fill cracks. The cracks are chiseled open into an inverted v-groove. They are then filled with hydraulic cement. The cement forms a rigid plug.
The problem with this method of repair is that the bond between the hydraulic cement and the concrete wall is poor. These seals are prone to efflorescence and water seepage after some time. Water pressure can force the plug off the wall. These seals last about 2 years.
- Epoxy injections
These are a popular seal for foundation wall cracks used by waterproofing contractors. They form strong and rigid seals. They however can only be used on dry surfaces. So, they cannot be used on an actively leaking crack. They don’t expand and contract with the concrete. The epoxy plug is therefore likely to fail after some time.
- Polyurethane injections
These injections make use of a polyurethane polymer that has high viscosity. The polymer bonds well to concrete and can be used even on wet surfaces. It is therefore a great option for sealing actively leaking cracks.
Polyurethane is a popular choice for repairing foundation wall cracks as it is flexible. It expands and contracts along with the concrete. This ensures that the plug won’t be compromised as the concrete shifts.
It is important to explore different options for repairing foundation wall cracks before making your final decision. Combine crack repair with waterproofing for the best results.
