Common Types of Below Grade Waterproofing

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.
