The Hydraform Interlocking Building System is different to conventional masonry, as it replaces regular masonry units and mortar, with Hydraform blocks that are interlocking and dry-stacked
Materials
A typical Hydraform block is manufactured using a mixture comprising of soil & cement which is compressed by means of hydraulic pressure. The preferred soil type is classified as a sandy – loam soil
- 8 – 25% Ordinary Portland Cement – 32.5 N
- Fine gravel (2 – 4.75 mm) 0 – 10%
- Coarse sand (0.2 – 2mm) 20 – 35%
- Fine sand (0.02 – 0.2mm) 20 – 30%
- Silt (0.002 – 0.02mm) 15 – 30%
- Clay (less than 0.002) 10 – 20%
- 5 – 10% water
Measurements
We manufacture and sell two sizes of blocks;
- Width: 180 mm, Length: 120 to 240 mm, Height: 115 mm
- Width: 150 mm, Length: 120 to 240 mm, Height: 115 mm

Block strength and quality is affected by cement type, cement content and curing duration (7 days minimum, 14 days recommended). Guidelines are based on fresh 42.5N OPC cement at 28 days and are approximations only. Other factors cab influence block strength. 1MPa (Mega Pascal) = 10kg/cm2 = 1000kPa = 145 psi
