Flood infusion treatment is common waterproofing method use in waterproofing contractor in Singapore. Flood infusion is a chemical-based treatment for waterproofing without hacking or other intrusive works.
Flood infusion technique utilises waterproofing chemical that are waterborne and to seal off concrete and masonry substrates. This method causes water to dry up and serves as a barrier to keep water out. It has high acidity PH levels to prevent corroding.
Flood infusion disadvantage would be the use of specially formulated solution consist of a combination of organic and inorganic polymers which will crystallize and form a sealer for dampness or seepage issue. These polymers provide surface protection with biocide (a chemical substance or micro-organism that destroy or exert a controlling effect on any harmful organism) used that are harmful to human, animal health or cause damage to natural or manufactured products. Such chemical which we refer to flood infusion, carry high toxicity due to their unspecific toxic action effect. Another common flood infusion disadvantage would be high exposure of such chemical are for industrial sectors or professional usage, potential exposure may indirectly expose through atmospheric and residential. We need to pay particular attention should to the exposure of vulnerable family member such as elderly, pregnant woman, and children as well as pets and other domestic animals can exposed indirectly following the application of biocidal products. Each substance in the mixture is to contribute to a mixture effect in direct proportion to its concentration and potency. Since these substances may act together to produce a combination effect, an assessment of the risk from each of these substances alone may underestimate the real risk from the product.
Flood infusion has its pro and cons, although this method is hassle-free, time saving cost friendly for homeowners, this method required tedious man labor and matter of hours to apply the chemical treatment. Flood infusion disadvantage would be chemical infusion solution which has Volatile Organic Compounds (VOC) which are solvents used in sealant that will evaporate and cause acute symptoms which include eyes, nose and throat irritation, headaches and dizziness and long-term chronic health effects.
As compared to flood infusion disadvantage, normal waterproofing method such as Polyurethane (PU) Injection grouting is a waterproofing technique that uses expanding injected polyurethane to stop water damage in voids, cracks concrete. This method is conduct on the underside of the seepage area or lower floor ceiling where the leak occurs.
Polyurethane is a liquid resin that injected into concrete during a leak repair, the polyurethane undergoes a chemical transformation from liquid to solid. It has a short curing time, low viscosity for sealing the leaks. It has flexibility allows later movement in the structure keeping the voids seal and prevent leak to occur.
Polyurethane have gained popularity in waterproofing industry. The most common application of polyurethane required the presence of liquid, moist or water which react to form a solid flexible foam. The materials are use in sealant and adhesive application that weatherability and resistance to chemical and environmental attack. A high-pressure polyurethane injection grouting machine is needed to conduct this progress, which pump the polyurethane grouts material under pressure into the concrete wall to stop water seepage from cracks, to fill voids under slabs, concrete joints or walls that are caused by water damage.
Polyurethane foams are classified as hydrophilic or hydrophobic. Both needs react with water which is present in the crack or premixed into the material. A hydrophilic foam system will entrap any excess water present within its structure during this foam formulation. These foams have high tensile strength, hardness and elongation to break. They are highly resistant to solvent. After curing, the grout will become a dense and elastic material.
Polyurethane sealant uses in waterproofing as well, these sealants dry quickly and moisture curing which is high utilized in waterproofing industry. It is widely used to seal the joints in waterproofing with firm bonding effect.
