Waterproofing 101: 4 Common Types of Waterproofing Systems

Waterproofing systems are mandatory on all below-grade surfaces that are utilised and subject to hydrostatic pressure. The architect or designer is responsible for specifying the optimal kind for the building to prevent ceiling leakage and costly repair. Four fundamental types of positive-side waterproofing systems are suited for commercial and home construction. The application methods for a waterproofing system depend on the material used.

Here are four common types of waterproofing systems:

  1. Reinforced sheet membranes.

Reinforced sheet membranes are the most prevalent type of system used in vertical applications, as their dependability has shown over the years. A membrane sheet is composed by applying a specially engineered polymer over a reinforcement to create reinforced sheet membranes. And the sheet applies with mastic and adhesive from the manufacturer. Typically, the support of the materials used for the waterproofing barrier results in a uniform application thickness on a metal roof waterproofing project in Singapore.

  1. Single-ply membranes.

Prevent water penetration and UV damage by applying modified asphalt, EPDM, SBS and atactic polypropylene modifications, and catalytically blown asphalt to the single-ply membranes to protect them from water penetration and degradation of concrete and roof waterproofing.

  1. Liquid-applied systems.

Liquid-applied membranes (LAMs) are installed directly onto the substrate in the field using different liquid components. These liquid systems typically require a primer followed by multiple coats of the liquid materials to overcome the surface tension of the substrate, which could lead to pinhole formation. Depending on the type of material and its viscosity, the required number of coats for waterproofing roof tiles varies from manufacturer to manufacturer.

  1. Hot-applied bitumen systems.

Since the dawn of waterproofing, hot bituminous systems have been a go-to for a water leakage specialist in Singapore. These systems incorporate multiple layers of fabric, felt, or a combination of felt and fabric. Alternating layers of bitumen (coal tar or asphalt) and felt are applied (fibreglass or organic). Bitumen functions as a waterproofing agent and adhesive. The reinforcement provided by the felts and fabrics stabilises the membrane and provides tensile strength.
