Article on waterproofing solutions for a home for Deccan Herald

Waterproofing of concrete structures like home, residential & commercial buildings, malls, housing apartments, high-rise buildings, etc. has gained much importance in recent years. The reason behind the same is very clear. A slight dampness or leakage in any home acts as a termite, which not only destroys the beauty ofit but at the same time it drastically affects its durability. The concrete is generally porous in nature and thus in the absence of waterproofing, the moisture or water whenever comes into its contact, gradually seeps inside the concrete through the capillary pores present on the surface & inside the concrete, resulting into carbonation of concrete & corrosion of reinforcement. Thus, the strength of the concrete comes down very fast and results into the collapsing of the concrete structure much before its life span. Thanks to waterproofing construction chemicals, which are very much effective and also readily available today to combat these accidents.

Today, due to advancement in R&D and technology sector, wide range of solutions are available for waterproofing starting from traditional mud-fast, kotastone, brick-bat coba, tarfelt, APP membrane systems to recently developed solutions like liquid applied acrylic polymer based cementitious coating, polyurethane coatings, integral waterproofing compounds, EPDM, PVC & TPO membranes, injectable grouts, etc., which are not only advanced, easy to apply& more effective but most of themare eco-friendly too.

We at CICO Technologies Limited today, upon continuous R&D efforts over the years, offer our clients innovative & reliable waterproofing products like integral compounds (CICO No. 1, CICO Super), admixtures as per IS:2645, acrylic polymer based coatings (Tapecrete P-151, Tapecrete RTU), Polyurethane coatings (Corchem 206 I, Aquapur), injectable grouts (CICO NSPGC, CICO Grout E1), etc. which aretime proven and widely accepted by Civil Engineers, Architects & Structural Consultants today.

Through our experience of over 80 years into the construction chemical industry, we could summarizeand share our learning on waterproofing into the following four basic principles ofwaterproofing, which when followed during the construction stage of home or any concrete structure with 100% commitment, can make it waterproof for its entire life span or until there is any structural failure:

  • Make the concrete dense and sound by water reduction with the help of admixtures/ plasticizers or using integral water proofing compounds
  • Provide a water barrier like waterproofing coatings/ membranes at the positive surfaceof structures like foundation & retaining walls in basement, wet areas (toilet/ balcony/ kitchen), terrace, overhead and underground tanks, swimming pools, podium slab, etc.
  • Take special care of construction joints by using epoxy bonding agent and other joints/ gaps between the pipes & concrete with suitable construction chemicals as these are the most vulnerable sources which aid into seepage of water into the concrete. Also, very important, whenever PVC pipes are used in plumbing work, the gaps between them & concrete must be sealed with suitable epoxy putty or epoxy mortar as they de-bond over time if sealed with some cementitious mortar.
  • Fill up the voids and cracks presentinside of underground concrete structures by injection grouting process.

For home owners, who engage small contractors for building their dream home can also always ensure to get done proper waterproofing course in their homes by independently consulting the manufacturers like us for guidance and technical support as integral waterproofing compounds and acrylic polymer based coatings have very easy application and can be carried out through semi-skilled mason upon guidance. For instance, integral waterproofing compound CICO No. 1 can be mixed during the preparation of concrete mix or sand-cement mortar to make it waterproof to a very large extent and acrylic polymer based waterproofing coating Tapecrete P-151 can be mixed with cement to achieve Tapecrete slurry and applied by sound nylon paint brush on positive surface of concrete to make it waterproof.

To conclude, we want to emphasize that Civil Engineers, Architects & Structural Consultants should come together and take a call to recommend and aid in spreading awareness to enhance the usage of waterproofing & other construction chemicals in every sector of construction industry to make the construction not only faster but safer, eco-friendly and reliable.
