Waterproofing is making an object virtually impervious to water.  Unless specific additives are included prior to pouring, concrete is not watertight therefore you need to use options to make an area waterproof. Waterproofing involves the application of a membrane (liquid or sheet) to act as a barrier between liquid and the building structure. We offer a range of waterproofing options.

Waterproof or water-resistant describes objects relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or under water to specified depths. Waterproofing describes making an object waterproof or water-resistant.

“Water resistant” and “waterproof” often refer to penetration of water in its liquid state and possibly under pressure. Permeation of water vapor through a material or structure is reported as a water vapor transmission rate. Modern items may be waterproofed by applying water-repellent coatings. Waterproofing is used in reference to building structures as well such as basements, decks, wet areas, etc.

In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents as well as protecting structural integrity. In building construction, waterproofing is a fundamental aspect of creating a building envelope which is a controlled environment.

Walls are not subjected to standing water and the water-resistant membranes used as housewraps are designed to be breathable to let moisture escape. Walls also have vapor barriers or air barriers. Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane even under the concrete slab floor where polyethylene sheeting is commonly used, or additive to the concrete to make it waterproof.

Over the past two decades, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials. Integral systems such as hycrete 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.

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.Waterproofing should not be confused with roofing, as roofing cannot necessarily withstand hydrostatic head, and waterproofing can.
