Can any Sealant Be Utilized to Fill a Concrete Crack?

Due to the brittle nature of concrete when it is subjected to strong traction, it is not uncommon to see Concrete Crack appear in it. This normal phenomenon in the life cycle of a structure is not synonymous with a design defect. Ground movement due to frost or water action is usually the cause.

In order to achieve adequate crack sealing, a number of criteria such as the type of surface come into play. In the context of concrete foundations, selecting the wrong product can lead to serious problems. The choice of the type of sealant also depends on the method envisaged. The repair can be carried out from inside the building or from the outside depending on the size of the crack.

Selecting the sealant for a concrete crack fixed from the inside

Quicker to implement, this repair technique has many advantages. Consisting of high-pressure injection of resin into the crack, it is the most economical and least restrictive solution. It is carried out in all conditions and allows the use of an effective sealant to seal a more or less narrow concrete crack through Utah helical pier.

Polyurethane foam

Offering great flexibility, polyurethane is an ideal sealing element for the residential sector. Its high-pressure injection is carried out from the inside in all seasons and even in the event of water infiltration. Depending on the thickness of the wall, the polyurethane foam penetrates and adapts to the shape of the crack, taking advantage of an expansion of seven times its initial volume. This quick-setting concrete crack sealer is distinguished by its elastic properties and relatively low cost.

Epoxy resin

Acting like a solder, epoxy shows great efficiency due to its powerful action. Like glue, it seeps into the crack to harden in three or four hours. Ideally intended for large buildings, an interior repair with epoxy resin limits new movements due to the vagaries of the weather. Utilizing it as a sealant to repair a concrete crack is more luxurious than polyurethane foam, but permits the structure to regain its complete strength. However, it is not recommended in a humid environment subject to infiltration. In the context of concrete foundations, selecting the wrong product can lead to serious problems. The choice of the type of sealant also depends on the method envisaged. The repair can be carried out from inside the building or from the outside depending on the size of the crack.

A sealant suitable for repairing a concrete crack from the outside

If the crack is too large, it is best to proceed from the outside of the building. Excavation work is, therefore, necessary to reach the affected area. Once the latter has been cleaned, an opening in the outer crack is made in a V-shape to apply the cement there through Utah foundation repair. The selected sealant is then used to fill the crack with concrete, before covering everything with a waterproofing membrane. A very reliable solution, but much more expensive than intervening from the inside.

Seek help from a specialist to be sure you are using the right sealant

When choosing the sealant to caulk a concrete crack, it is, therefore, necessary to carefully study its characteristics. A specialist will be able to select the most suitable method and the corresponding product. You must contact a professional who has solid experience in the field of repairing foundation cracks. In the context of concrete foundations, selecting the wrong product can lead to serious problems. The choice of the type of sealant also depends on the method envisaged. The repair can be carried out from inside the building or from the outside depending on the size of the crack.
