Negative & Positive Side Waterproofing

Water and moisture dripping noticeably decrease the value of a basement be it a storage space for you or a play room for kids. When your basement damp in to moist, the possibilities to have the formation of mold becomes favorable. And, if the mold get space to grow, it will frequently produce bacteria and discharge into the surrounding air causing further deterioration through the rest of the building. This not only causes a fusty smell but also effects on the living quality and even cause health ailments.

At Affinity Building Solutions our new and corrective installations includes both negative and positive side waterproofing that definitely puts a check on such abrasions and damage. Positive-side waterproofing works on direct exposure to water or similar moist conditions whereas negative-side waterproofing is more preferred to the opposite or interior side from which water occurs.

While both systems have discrete features, the majority goes with positive-type systems. Negative systems has a limitation to cementitious-based materials that are often considered for remedial applications. But, here a twist. When some waterproofing materials are applied to negative sides of a building structure the results comes in favor of positive-side waterproofing.

The materials used remedial applications on the negative side of a structure include

  • chemical grouts
  • epoxy grouts
  • Pressure grouts

A classic example of negative side waterproofing is when water leaks through basement walls and the waterproofing is performed from the inside. In general, negative side waterproofing is tougher to achieve with 100% results than positive side waterproofing as the water pierces through the construction support behind the waterproofing material and pushes it off the substrate.
