Description
Durable, Versatile & Engineered for Ghana’s Construction Standards
Regimanuel Concrete Products’ Construction Hollow Blocks are precision-engineered using high-grade aggregates from our in-house quarry, ensuring consistent strength and dimensional accuracy. Designed for both load-bearing and non-load-bearing wall systems, these hollow blocks offer a cost-effective and structurally sound solution for residential, commercial, and industrial projects across Ghana.
The hollow cores reduce the weight of the block, facilitate easy handling, and provide thermal insulation advantages while still maintaining excellent compressive strength. RCP’s hollow blocks are produced to meet rigorous quality standards and are available in multiple sizes to suit various design requirements.
Available Sizes:
- CHB 5” – 450 × 125 × 200 mm
- CHB 6” – 450 × 150 × 200 mm
- CHB 8” – 450 × 200 × 200 mm
- CHB 9” – 450 × 225 × 200 mm
Each block offers a compressive strength of 4 N/mm², with higher strengths available upon request for specialized applications.
Ideal Applications:
- Partition walls
- External and internal structural walls
- Fencing and perimeter walls
- High-rise developments (when reinforced with concrete and steel)

Frequently Asked Questions
A: We manufacture solid concrete blocks in standard Ghanaian dimensions:
- CSB 4″ (450×100×200 mm)
- CSB 5″ (450×125×200 mm)
- CSB 6″ (450×150×200 mm)
- CSB 8″ (450×200×200 mm)
- CSB 9″ (450×225×200 mm)
Higher strength classes (up to 6 N/mm² or more) are available on request.
A:
- Solid blocks are ideal for retaining walls, boundary walls, and load-bearing walls where high strength and minimal moisture ingress are required.
- They offer enhanced sound insulation and fire resistance compared to hollow units.
- Hollow blocks remain preferable for multi-storey building cores when lighter weight is desired.
- Solid blocks are ideal for retaining walls, boundary walls, and load-bearing walls where high strength and minimal moisture ingress are required.
A: A 1:5 cement:sand mortar is standard for solid block walls. In coastal regions (e.g., Takoradi), a 1:4 mix with waterproofing additives improves durability. Joints should be kept at 8–10 mm thickness and fully filled to prevent water seepage.
A: Yes. Their dense mass and lack of large voids reduce capillary action, making them more resistant to damp penetration—important in Ghana’s rainy season. Adding a surface waterproof coating or damp-proof course further enhances performance.
A: Block pricing varies by size, strength, and quantity. For tailored quotes—including bulk discounts and delivery to Accra, Kumasi, or Tema—please contact us for pricing (Phone: +233 27 776 2259). We ensure competitive rates and reliable logistics from Dodowa quarry.
A: Absolutely. All solid blocks meet GSA GS CS 15:1990 and BS EN 771-3 standards for masonry units. We perform routine tests for compressive strength, water absorption, and dimensional accuracy to guarantee consistent quality.
A: Minimal upkeep:
- Inspect mortar joints annually and re-point as necessary.
- Apply weather-resistant paint or sealant every 5–7 years to maintain surface integrity.
- Ensure proper drainage at the wall base to prevent standing water.
A: Standard stock of CSB 4″–9″ is available for same-day dispatch within Greater Accra. For large or custom-strength orders, lead times are typically 3–7 days. Contact our sales team at +233 27 776 2259 to confirm availability and schedule delivery.
