Why You Should Waterproof Exterior Walls of your home?

Waterproofing protects your concrete or wooden structures, from water damage.

Waterproofing helps prevent water intrusion that could weaken concrete or wooden structures/foundations or lead to their disintegration over time.

The cost of repairing a foundation damaged by water intrusion is much higher than the cost of waterproofing your basement, crawlspaces, and other parts of your home that are particularly susceptible to water damage.

By waterproofing, before you have a problem, you can prevent foundation damage and save yourself a lot of grief and expense later on.

Why Seek Professional Advice?

There are various types of waterproofing products, but not all of them can protect your foundation from water damage. Different situations also call for different solutions. There are products you must apply to the exterior wall; there are others that you can use on the interior wall. If you apply the wrong waterproofing product or use an inappropriate waterproofing method, you'll waste your money.

The expertise of a foundation contractor like Sinai Construction Engineering will help you save money. Our experience in waterproofing means that your can depend on us to recommend and use the waterproofing solution that best fits your situation so no money and time are wasted.

Typical Waterproofing Solutions

Waterproofing and protective coating solutions come in a variety of forms. They can be applied to above-grade or below-grade decks, exterior walls, slabs, foundations, retaining walls, or basement walls.

Waterproofing materials are often rubber-based and have the ability to bridge cracks. Foundation waterproofing products should be distinguished from some damp proofing products which are tar-based and will not provide waterproofing protection.

There are also various types of waterproofing methods, but the two most common methods are waterproofing membrane installation and crystallization.

Exterior Waterproofing

Typically, a water intrusion problem is addressed by excavating along the exterior side of the wall (e.g. the foundation wall or the retaining wall) and applying waterproofing compounds or a waterproofing membrane to this exterior wall.

NOTE: Waterproofing membranes should be accompanied by good drainage to be most effective. This involves excavating a trench within which a perforated drain pipe surrounded by gravel wrapped in fabric could be placed to drain excess water.

Concrete Waterproofing by Crystallization

If it is not possible to apply waterproofing to the exterior side, there are special waterproofing products that may be applied to the interior side of the foundation or retaining wall. This method requires several months of curing before the special waterproofing products can completely crystallize throughout the entire wall and make it proof against water intrusion.

Whichever waterproofing solution is used, it is important that it be executed correctly and the waterproofing product be applied properly. Thus, it is imperative that you choose an experienced foundation contractor that can correctly implement the appropriate waterproofing method.
