Do We Really Need Concrete Waterproofing
The decision to embark upon concrete waterproofing is not to be taken lightly. This is particularly true when you contemplate the behavioural differences that there are when organic and chemical compounds are mixed. One can not always be certain of the outcome. That being so, the first decision should be to consider the actual condition of the concrete you will be working with and its position in respect of water.
Although it is true to say that the topical asphalt based sealers are typically the first choice for most concrete work, being as they are, tried and tested against problems with foundations and brickwork, there are alternatives. There is an ongoing evolution in methodology and product development in the current manufacturing processes. As an example many new additives are being created to improve the protective qualities of sealant against water erosion and water vapour in particular. The encroachment of water into concrete can have a highly damaging effect rendering the structure prone to weakness.
There are new topical sealants that have the job of sealing out all water on the market. These types of sealers are formulated and graded according to how much waterproofing is required.
According to experts, these types of sealers are perfect for giving excellent protection, creating a chemical barrier for swimming pools and ponds. This is a major plus factor for the do it yourself guy. In fact, the coverage of the sealers is up to three hundred and fifty square feet. The solution can be rollered, brushed or pressure sprayed on. As an added benefit, any graffiti problem can be dealt with easily since the sealer provides a non-stick surface similar to Teflon coating.
It is said that these sealers are ideal for providing a great chemical barrier for swimming pools and ponds. Perfect for the regular do it yourself kind of job! They can be broadcast up to three hundred and fifty square feet or more. You can spray on through a pressure hose or brush or roller on the mixture. An added bonus is that this kind of sealer acts also as a defence against painted graffiti, providing a similar non-stick surface as Teflon coating.
There are also products on the market whose foundation is based on the new crystal technology. It is a simple idea; because concrete is porous by nature if you mix a special type of crystal to the mixture, as the crystals grow and expand they automatically close up the gaps in the concrete. It is a very efficient technology for sealing up those hairline cracks that often appear overtime. The crystalline mixture can be troweled in to fresh concrete, sprayed on, added to water and simply applied to existing or new structures.
Additives such as silica and pozzolan are also added in order to provide more water protection and strength further benefit is the fact that these latest products form a barrier against erosion from all kinds of oil-based products that damage the concrete structure. This adds an element of protection against future erosion for your concrete waterproofing project.
