Product Overview
300mm Celcon H+H Standard Aerated 3.6N Concrete Foundation Block, designed for below-ground foundation walls and courses below damp proof course.
Provides strength, insulation, and reliable support in low to medium-load residential and commercial applications.
Features & Benefits
- Compressive strength 3.6N/mm²: Suitable for foundation work in multi-storey buildings and heavy-load areas.
- Lightweight aerated concrete: Easier to handle and install, reducing labour effort on site.
- Thermal efficiency: Aerated structure provides better insulation than dense concrete blocks.
- Class A1 fire resistance: Non-combustible, meeting the highest standard for fire safety.
- Frost resistance: Withstands freeze-thaw cycles for long-term durability in varying climates.
- Sulfate resistance (DS1–DS4 soils): Reliable in mild to severe sulfate conditions below ground.
- Quality assurance: Manufactured under strict controls for consistent strength and performance.
- Versatile application: Suitable for foundations, solid walls, cavity walls, and beam & block flooring.
Applications
- Foundation walls (below DPC): Provides a stable, load-bearing base in residential and commercial construction.
- Solid or cavity walls: Supports a wide range of wall designs for structural flexibility.
- Suspended floors: Compatible with beam and block floor systems for ground or basement levels.
-
Framed construction support: Used below ground to stabilise structural frames in framed buildings.
Installation Guidance
- Laying below ground without mortar perpends: Ensures proper drainage and installation efficiency.
- Follow engineer’s embedment depth requirements: Guarantees foundations perform to structural design.
-
Bed blocks on suitable mortar: Provides stable seating and maximises load-bearing capacity.
Compliance & Performance
- Compressive strength 3.6N/mm²: Meets structural requirements for foundation blockwork.
- Sulfate condition suitability (DS1–DS4): Designed for use in soils with low to high sulfate levels. Resistant to sulfate attack in categories DS1 (mild exposure) through DS4 (severe exposure), ensuring durability across a wide range of ground conditions.
- Please Note: Blocks are designed for below-ground use and must be laid without mortar perpends when installed underground. Always follow engineer’s guidance for load-bearing requirements and soil condition suitability.
- Pallet Charge: Orders requiring a pallet will incur a refundable pallet charge. Our customer service team will confirm if this applies to your order.
