Concrete cover — the distance between the outer surface of concrete and the nearest reinforcement bar — is one of the most critical parameters in RCC construction.
Why cover blocks matter:
1. Corrosion protection: Insufficient cover allows moisture and chlorides to reach the rebar, causing rust and structural failure.
2. Fire resistance: Adequate cover ensures the structure meets fire rating requirements.
3. Bond strength: Correct cover ensures proper anchorage of the reinforcement.
Why choose PVC over cement cover blocks?
- PVC blocks do not crack or crumble during concrete pouring
- They maintain exact cover dimension throughout the pour
- Available in 20mm, 25mm, 40mm, 50mm and 75mm sizes
- Lightweight and easy to clip onto bars
Surya Engineering supplies PVC cover blocks in circular, square, footing and clip-type variants across Mumbai and all of India.
