How to Waterproof Residential Foundations

Ever wondered how to make your residential foundation waterproof or water resistant to prevent the transmission of both water and vapor, to keep the concrete strong and water tight. In the earlier days traditional methods were used for waterproofing by using hand applied solvent-based asphalt product but they would only create a damp-proof environment and not complete waterproofing the foundations.Over the last ten years the construction & concrete cutting Melbourne industry has made remarkable technological advances and now a days very advanced waterproofing methods & materials are used.

Various Types Of Waterproofing Materials

Basic materials that are available today for waterproofing :

Solvent-based asphalt emulsion.  This solvent is generally sprayed or applied with hand trowels which is heated to make a spray-able liquid.Very popular in the earlier times but as of today very rarely used.

Rubberized asphalt.  The most commonly used waterproofing substance either as “peel and stick” sheet material or as a spray-able liquid.

Rubber.  A sprayed material, made from a mixture of synthetic polymer and a chemical solvent which can be applied at temperatures as low as 17° F because of its liquid based state.

Polyethylene. A three-layer sheet membrane system is made by using polyethylene.

Bentonite.  Bentonite clay is also extensively used to prevent the flow of water. Bentonite when mixed with water, expands and becomes a thick gel like substance.

Spray-able Membranes Installation

When spray-able membranes are used concretes are not required to be cured before installation.Its convenient to use the spray-able membrane.

Sheet Membranes Installation

Construction contractors who doesn’t prefer or own spray equipments, they generally go for “peel and stick” products.

Oil Based Waterproofing

Its like a primer which is primarily used to prevent water leakage from roofs after construction.
