Basement waterproofing is necessary for any home if you want to keep the moisture out. It’s also necessary for preventing structural damage and related moisture problems.
Waterproofing sealers are often used for waterproofing concrete slabs and foundation walls.
How concrete waterproofing sealers work
Despite what many people believe, concrete is a porous material. Pores in concrete absorb water slowly through a process known as capillary action.
The results of water seepage in a concrete foundation vary depending on how long the seepage has been going on for, the cause of the seepage, as well as the construction of the slab.
Concrete is alkaline in nature. It has a pH of 9. When exposed to moisture, the water dissolves alkalis from the concrete. These react with many waterproofing coatings. The coatings therefore weather with time and begin to feel away from the concrete wall.
A waterproofing sealer is thus necessary to prevent these reactions. The sealer neutralizes the alkalis to protect the waterproofing system.
Waterproofing sealers are mixes that are designed to bind to different surfaces. The sealer is applied to the surface as a liquid. When it dries, it forms an insulating layer on the surface of the concrete. This layer is impermeable to moisture. The layer can also withstand all types of weather conditions.
The process of applying a sealant can be slow and tiring. It requires some level of skill and knowledge to ensure that the process is successful.
Some sealants dry to form a smooth surface. This may have an appearance that is similar to the surrounding walls. You therefore won’t need to have another floor treatment to get your floors to look presentable. However, these types of sealants are more expensive than other sealants.
How effective are sealants
Sealants are a highly effective way to keep moisture out of your basement. They can be used on newly constructed basements as well as those that have been in existence for several years.
Another great thing about sealers is that they can be applied on a wide variety of foundations. They are effective for waterproofing foundations constructed from blocks, cinder blocks and poured concrete.
Spray on sealants are available for ease of application. These greatly reduce the time required for application. It also makes it easy to apply the sealant to those hard to reach areas.
