Seal It Right from the Start: Why ADT Mix LW+ Is India’s Smartest Integral Waterproofing Solution
The Science of Waterproofing: Why Concrete Fails
While concrete appears to be a solid
and durable material, a closer examination under a microscope reveals a complex
internal structure filled with numerous pores and micro-capillaries. These tiny
channels, which often go unnoticed, play a significant role in the material's
behaviour. They enable the infiltration of water,
salts, and various aggressive chemicals, which can gradually permeate the
concrete. As these substances seep in, they initiate a series of chemical
reactions and physical processes that can compromise the integrity and strength
of the structure over time. This
breakdown can lead to issues such as cracking, spalling, and overall
deterioration, emphasising the importance of understanding and addressing the
vulnerabilities of concrete in construction and maintenance.
Common Damage
Due to Moisture Ingress:
●
Steel Reinforcement Corrosion – rusting
weakens the core
●
Efflorescence – white salt deposits on
plaster
●
Cracking – due to drying shrinkage and
water movement
●
Seepage in bathrooms, balconies, and tanks
●
Fungal and algae growth – leading to
unhealthy interiors
📊 Fact: More than 70% of water-related concrete failures in India are
traced to insufficient internal
waterproofing, as per IS 2645:2003 studies.
Traditional Waterproofing
vs. Integral Waterproofing
🔧
Traditional Methods:
Surface coatings, membranes, and
post-construction treatments are essential components in construction and
maintenance projects aimed at enhancing durability and protection. Surface
coatings, which can include paint, sealants, and protective films, provide a
barrier that helps resist moisture, chemicals, and abrasion. Membranes, often
made from materials like rubber or thermoplastic, are specifically designed to
offer waterproofing and prevent water infiltration in various structures, such
as roofs and basements. Post-construction treatments, which encompass
applications like waterproofing agents and curing compounds, work on surfaces
after the initial construction is completed to further safeguard against wear
and environmental damage.
While these solutions are incredibly useful
for improving the longevity and performance of buildings, they tend to be reactive rather than proactive. Over
time, exposure to environmental elements, wear and tear, and chemical interactions
can lead to the degradation of these materials, potentially compromising their
effectiveness and necessitating maintenance or replacement.

Waterproofing:
This innovative technology safeguards
concrete from the inside out during
the mixing process. By working at the molecular level, it effectively prevents
water from penetrating the material, guaranteeing a lasting waterproof
solution. This means that the concrete
not only remains resilient against water
damage but also enhances its overall
durability, making it suitable for various applications where moisture
resistance is crucial.
What Is ADT Mix LW+?
Understanding the Product
ADT Mix LW+ is a liquid integral waterproofing compound developed by ADT Industries, engineered to meet
Indian site conditions and IS 2645:2003 guidelines.
It works by modifying the internal
structure of the concrete matrix, reducing porosity and increasing durability,
even in extreme environments.
Key
Properties:
●
Liquid Formulation – easy to mix, no
clumping
●
IS 2645:2003 Certified
●
Chloride-Free – safe for reinforcement
●
Non-toxic and Eco-friendly
●
Compatible with OPC, PPC, and blended cements
How ADT Mix LW+ Works: The
Internal Shield Mechanism
Once mixed into concrete or mortar, ADT Mix LW+ reacts chemically with
calcium hydroxide released during cement hydration. This reaction:
●
Fills capillaries and
micro-cracks
●
Forms a hydrophobic
(water-repelling) barrier
●
Enhances the density and
cohesion of the mix
●
Prevents future ingress of water,
salt, and harmful chemicals
This mechanism turns the entire volume
of concrete into a self-protecting,
water-resistant material.

Dosage Guidelines and
Application Process
Recommended
Dosage:
●
100 ml to 250 ml per 50 kg of cement
(0.2%–0.5% by weight)
Mixing
Process:
- Pre-measure the required quantity of ADT Mix LW+.
- Add it to
the first portion of gauging water.
- Mix
thoroughly into the concrete/mortar.
- Add the
remaining water and mix until uniform.
- Apply and cure as per standard practice.
Important:
●
Do not overdose; this may
slightly delay setting time.
●
Ensure proper mixing for full
dispersion.
Where to Use ADT Mix LW+
