Waterproofing Contractors in Bronx

Waterproofing is not a topic of debate today, it definitely got necessary as soon as human beings needed shelter to live in. Thus, waterproofing has remained a need since centuries. Earlier people looked for this protection from natural elements which existed at that time. As years passed, the renovation and advancement brought significant alterations in materials and types of waterproofing. The material and types of waterproofing differ in accordance with the place. Let’s delve into the complete detail of waterproofing around Bronx, Yonkers and Westchester County NY.

Basics of Waterproofing

A number of constituents contribute to a waterproofing system, like drainage mixtures which come in the way of water and take it away from the structure, links between façade and base membranes, and watertight sanitation in food service zones.

You cannot brush-off the importance of impervious membranes when these come to talk about vital constituents of waterproofing. Whether it is foundation wall, basement tunnels or fountains, lobbies and kitchens, impervious membranes are crucial for all types of waterproofing.

Building Cladding materials like brick masonry cannot be waterproofed in actual; rather act as weather barriers. Only the use of impervious membranes hinders water entry into the building. You need to understand that there is a clear difference between waterproofing and roofing. Building decks over covered spaces are waterproofed and technically not a roof. The builders will clearly make distinction, due to the fact that waterproofing applications offer far less warranty span in contrast to some roofing systems.

Sides of Waterproofing

Before heading towards the design and materials for waterproofing, it is essential to know where, when and why waterproofing needs to be installed. There are mainly three options including:

  • Positive-side waterproofing
  • Negative-side waterproofing
  • Integral waterproofing

Integral waterproofing accumulates mixtures that are amalgamated into concrete blend during initial discharge. These products are extremely weak and are not matter of discussion here.

Positive waterproofing is used in exterior face or wet base on grade and below grade, and to suspended slabs too. It is primary waterproofing type used nowadays. These applications comprised almost all commercial waterproofing or damp proofing systems. If accurately installed, positive-side waterproofing ensure the protection of interior and structural components i.e. concrete or steel from moisture and water infiltration. Below-grade positive side incorporate fluid applied membranes, hydro clay, vapor barriers and sheet membrane systems.

Positive-side waterproofing hinders water and moisture from entering the substrate surface which is a predominant benefit of this system. The substrate is shielded from freeze-thaw sets and destructive chemicals in the groundwater. But this system cannot be repaired once installed which is its big disadvantage. Once got damaged, you need to remove all topping i.e. landscaping, concrete and dirt etc. which make you pay heavy restoration cost.

Negative side waterproofing is used chiefly for water holding purposes as in dry or inside face of the subsurface. This waterproofing system does not allow water from entering into covered spaces. Be that as it may, negative-side waterproofing cannot avoid water entering the substrate. The materials used in this type of waterproofing are epoxy shots and cementation coverings which can easily withstand hydrostatic pressure.

In market, crystalline or acrylic additives are easily accessible which can be applied to negative-side waterproofing, penetrating into the substrate and eventually hinder water entering in the substrate. Unlike positive-side waterproofing, this system is super easy to get repaired. You need not remove the whole surface, if any touch-ups or repair is required.

Moisture entry permitted into the substrate on negative side waterproofing systems can be considered as a benefit, because it stimulates active curing of the concrete substrate. Or it can be a drawback as it adds to the deterioration of the concrete and steel reinforcements from groundwater and chemicals.

When to use Positive-side or Negative-side Waterproofing?

The final decision to use positive-side or negative-side waterproofing should be made after giving a look-see over certain conditions. If there is exposure to corrosive soil materials, free cycling or there are some interior humidity limitations, you need to consider only positive-side waterproofing. If no, then negative waterproofing should be considered.

Why Positive-side gets over Negative-side Waterproofing?

When it comes to decide the most proficient form of waterproofing, the professional water-proofers suggest installing positive-side waterproofing for better protection of structure. The negative-side waterproofing is risky as it is unable to stop liquid or vapors to infiltrate the concrete. Waterproofing applied to the negative-side of the structure also be responsible for a passage for any ground restraints or chemicals to enter into the substrate and worsen the concrete and rust steel cavalries.

To eradicate these fears, it is possible to install a negative-side partition wall to clench the waterproofing in place. This method may prove to be expensive than digging the surface. The finest solution is to apply positive-side waterproofing on newly constructed structures and bound negative side waterproofing to curative applications.
