Have you come across buildings and most often houses that sport balconies with brownish/ greenish staining underneath? Well that is an obvious give away to a half-hearted water proofing job. Concrete when exposed to the water directly is vulnerable to, leaching which refers to minerals in the concrete dissolving into water and being deposited elsewhere. This is caused by the constant water flow through the cracks of the concrete. Sea water in particular advances this dampening therefore beach/ water front properties need a through water proofing job done. The buildings of the past did not essentially require water proofing as they were built on stone and lime based mortars topped off with soft water based paints allowing the very little damp that might seep through to be dried off.
But the present day building materials such as concrete and bricks inherently lets the damp pass-through and is why in today’s context water proofing is very important. In brief water proofing refers to the preventive measures to keeping this from happening and requires a lot of skill along with long standing experience that will allow to confidently asses the size and complexity of the project at hand. Along with relevant engineering knowledge it is also important for a professional waterproofer Sydney in the industry to fulfil any legal obligation that might occur in the line of work by obtaining a Home Warranty Insurance with a public liability insurance cover and a cover that ensures a safe environment for his team members.
Remedial waterproofing is the most common and recurrent form of water proofing that addresses touch ups or corrective measures taken to ensure that the moisture and damp does not get to the building. The damp stains that appear on the most top floor or the most grounded floor is a clear indication of a situation to be looked into and those specific floors are often effected first as they have more probability to direct contact with water. This is a job that needs more skill and knowledge as a poor job can lead to complications such as mould or pooling.
The technicality of systematic water proofing is of two folds
1) Stop the water entering the building and
2) Give the water somewhere to go.
As simple as it may sound in writing it is quite a complex job which had so many variants to consider and during the job it is also important to adhere to legal, ethical and moral responsibilities, such as not employing material that contains asbestos and being accountable when re channelling the flow of water away from the building.
