Gunite is often used in construction and repair of basement. The versatility of the gunite makes it a good choice for repairs, and it adds strength while leaving a smooth surface. Gunite can be sprayed into foundation cracks with little or no preparation work and not only adheres to previous gunite applications but can also be applied to most surfaces including spit and stone walls in ruined.
Gunite (occasionally called Dry Piston Concrete) is a form of sprayed concrete, and is similar to that of shotcrete but with artillery, water is mixed with dry mix Cement and aggregates to the nozzle during its application. The nozzle man adjusts the amount of water that is added to the mixture and has total control of the cement / water ratio. The mixture is sprayed at high speed to create a smooth concrete surface. Gunite is often sprayed on steel bars or meshes in a new construction for more strength and can be sprayed in basements, pools, retaining walls, water gardens And even overhead.
The inner walls of the Gunite basement construction are often covered with a plaster plaster to waterproof the basement. The plaster is similar to what you will find on the surface of a swimming pool. This plaster coating may sometimes crack and chip, making the wall worse and leaving an unprotected area until the waterproofing is done. To repair these cracks, you must remove all bulk materials and remove any debris from the surface. Once the area is prepared, you can perform the repair simply by replacing the plaster cover.
Changes in temperature and decantation of the soil can cause more cracks in the walls and the soil of the subsoil. If you have a crack in your basement that goes beyond the surface coating and into the gunite, it can be repaired in different ways. First, you can choose to repair using an epoxy compound by filling the crack. Kits are available for do-it-yourselfer to repair small cracks in foundation and basement walls.
A second way to repair your basement wall is to fill it up using a concrete sewing system that places staples through the crack. These staples are made to prevent the crack from opening again. To place the staples, you should drill holes for the staples and remove the surface coating in the area where the staples will be installed. Once you have the staples in place, you can fill the crack using any type of quick setting cement without shrinking.
If the damage to the basement is sufficiently extended, you can choose to repair it using gunite. This can be done even if the original basement was not built in gunite. Gunite will adhere to most surfaces. It is best to have a professional hand trained in the gunite in your basement because if the wet / dry mix ratio is not correct or the gunite is not blown properly (And evenly), you may encounter structural problems.
Repairing an existing basement with gunite requires that you put a uniform coating of gunite on the surface. Pulling the gunite on the surface will fill the cracks and strengthen the surface. Applying gunite to your basement helps repair any cracks and chips you may have and this will make your basement look like new.
