Current Updates of Waterproofing System

Date: 06.07.2012 | Updates

For buildings whether they are new or old constructions, it is necessary to have waterproofing system in place since concrete itself will not be watertight on its own. In the past, the system of waterproofing involves ‘membranes’. Membrane is an application with one or more layers of various materials for  e.g., bitumen, silicate, PVC, EPDM etc. These membrane materials act as a barrier between the water and the building structure, preventing the passage of water. However, the membrane system relies on exacting application, presenting difficulties. Problems with application or adherence to the substrate can lead to leakage.

With continuous improvement of technology, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials.

Integral systems work within the matrix of a concrete structure, giving the concrete itself a waterproof quality. There are two main types of integral waterproofing systems: the hydrophilic and the hydrophobic systems. A hydrophilic system typically uses a crystallization technology that replaces the water in the concrete with insoluble crystals. Various brands available in the market claim similar properties, but not all can react with a wide range of cement hydration by-products, and thus require caution. Hydrophobic systems use fatty acids to block pores within the concrete, preventing water passage.

Currently, there are introduction of new membrane materials that would perform better in waterproofing than the older methods like PVC and HDPE. Generally, new technology in waterproof membranes relies on polymer based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.
