While damp proofing and waterproofing sealants are used in a variety of circumstances, some jobs require an even higher level of protection against water damage.
Either because of specialized concrete that is particularly vulnerable or because of unique exposure the construction may be subjected to, a higher level of water protection is used, referred to as water repellent. This particular application works by treating concrete with a hydrophobic solution, which not only blocks water from seeping into the concrete, but actively repels it. The solution may be applied by itself or in combination with other treatments, depending on the requirements for the specific job in question.
For example, a common application is to use a mixture of silane and siloxane. Silane molecules are some of the smallest available in concrete sealants, and penetrate the concrete, developing bonds with the molecules found within the concrete itself. The silane then blocks water from being absorbed within the porous concrete structure. Siloxane, meanwhile, adheres to the exterior surface of the concrete as a far larger molecule, blocking water from entering from the exterior. Both chemicals are hydrophobic and actively repel water molecules, providing advanced protection against water damage.
There are a variety of water repellent treatments that can be applied, and each has their advantages in given situations. We are able to provide clear advice on which is best for your particular job and apply it correctly to ensure long lasting protection.
