Common Types of Below Grade Waterproofing

Most building owners understand above-grade waterproofing systems. These are the systems that you use on your outdoor deck or floor space. However, if you have a basement or below ground deck, you might want to think about below grade waterproofing. The following information can help you decide what kinds of waterproofing systems your building requires.

Positive Side
Positive side waterproofing may work best with foundation waterproofing. This is because you have to have access to the exterior walls to apply this coating. If you cannot access the exterior walls, then the other options are best.

Blind Side
When working with structural slabs, your contractor would apply blind side waterproofing to the underside of the structural slab. If you have limitations when it comes to coating application, blind side is best.

Negative Side
When it comes to basement waterproofing, negative side is when you apply the waterproofing material to the interior surface. For basements and foundations, there is a chance for the material to crack over time. If you discover cracks later, you can add more waterproofing to repair damage.

Drainage
Even if you have waterproofing systems applied, you should still consider whether you need drainage. When you use a waterproofing team, they can help you decide which options would be best for you. Often, contractors install french drains for under-slab systems. If you have a flat area, you may need a sump pump.

Below grade waterproofing can prevent future water damage to your building. Water damage can threaten the structural integrity of a building and lead to mildew or mold growth. Basements and foundations should always be waterproofed.

Some Ways Water Can Destroy Your Structures

Water may be a life giver everywhere else, but when it comes to construction, it can be one of nature’s most destructive elements. Whether it’s roofing, flooring or foundations, water infiltration can cause everything from weakening to erosion to complete destruction. When embarking on a new project, it can be tempting to cut cost corners by holding off on hiring a waterproofing contractor. Unfortunately, you’ll pay in the end. Don’t believe it? Read more about these ways water can destroy your structures to see why proper waterproofing matters.

Freeze-Thaw Cycles

When you rumble across a pothole, thank freeze-thaw cycles. This is one of the most common and well-known ways that water can be destructive. Water can seep into concrete and later, when temperatures drop, freeze. The resulting ice expands, pushing apart concrete and causing cracks and spalling. This is one of the most common causes of destruction to sidewalks, but it also can impact stucco walls and even asphalt.

Steam Damage

Steam can be a surprisingly destructive element in homes and businesses. The classic example occurs when a bathroom is built with no attention to waterproofing. Instead, it’s assumed that tile and epoxy grout will repel water. Instead, steam seeps in and soon water begins running down walls. A waterproofing contractor can prevent this type of outcome in commercial locker rooms and other water-prone areas with a few simple steps.

Frank Flooding

This is the most obvious threat but one that people still often don’t plan for. Proper waterproofing from a qualified waterproofing contractor is critical when a building is built at or below ground level. Ignore this and you start along the path to gradual leaks and flooding that will erode your foundation and potential threaten the entire building.

It’s simple enough to find a good waterproofing contractor and keep your structures dry. But it starts with research. Consider these tips, do your homework and you’re sure to find the perfect waterproofing professional for the job.
