Protect RCC Foundation Slabs with Crystalline & PU Waterproofing by EMERGE INFRA

The mother concrete (or base RCC slab) plays a vital role in supporting your building’s flooring system. Without proper waterproofing, water can seep through tiles or joints, leading to moisture damage, cracks, and long-term structural issues. EMERGE INFRA offers expert mother concrete waterproofing solutions in Chennai, using Crystalline and PU-based coatings that penetrate deep into the concrete and provide lasting protection.

What is Mother Concrete and Why Waterproof It?

Mother concrete refers to the structural RCC slab located directly beneath floor finishes such as tiles, granite, or marble. These slabs are often exposed to water from bathrooms, kitchens, balconies, or weather-exposed areas.

Waterproofing is essential because:

  • Moisture can seep through tile joints and grout
  • It weakens the RCC over time and promotes rebar corrosion
  • Mold and mildew can develop on the underside of the slab
  • Water leakage can affect rooms or levels below
  • Preventive waterproofing increases the life and stability of your structure

Our Mother Concrete Waterproofing Procedure

EMERGE INFRA follows a detailed and proven waterproofing process to ensure total surface sealing:

  1. Surface Preparation: Leveling and cleaning of the RCC surface to remove dust, debris, and loose material
  2. Application of Crystalline Slurry: Deep-penetrating GBC crystalline waterproofing is applied to seal internal capillaries
  3. Crack Filling & Joint Sealing: All cracks and cold joints are sealed with GBC chemical grout and joint sealer
  4. Membrane Coating: 2–3 layers of PU or cementitious waterproof membranes are applied to form a flexible, protective barrier
  5. Curing & Screed Layer: A protective screed is laid on top to prepare for tile or floor installation and resist mechanical wear

Recommended GBC Products for Mother Concrete

We use only BIS-compliant, high-performance GBC (Golden Building Chemicals) products for long-term reliability:

  • Crystalline Waterproof Coating – For deep concrete penetration
  • PU Coating – Flexible membrane for superior surface sealing
  • Cold Joint Sealer – Ensures leak-proof joint sealing between construction pours
