Precast Concrete Blocks in 5 Sizes: How to Choose for Container Supports and Solar Panel Bases

Short answer: CCP precast concrete blocks come in 5 sizes, from 15×15×15 cm (7 kg) to 50×50×30 cm (175 kg). They support office container legs above the ground, act as ballast for solar panel frames, and serve as equipment bases. A container under normal load uses 6 blocks; choose the block height for the clearance you want under the container floor.

Concrete block sizes and weights

Every block is factory-made, with consistent size and weight.

Container supports: how many blocks and which size

1. Quantity: a container under normal load uses 6 blocks
2. Height: choose for the clearance you need under the container floor: blocks are 15, 20, 30 or 40 cm high (see table)
3. Extra weight: if the container holds heavy goods or machinery, users may need to take the added weight into account
4. Prepare the ground: the surface should be flat, firm and level

Solar panel bases and equipment bases

• Place under solar panel frames as ballast; quantity and size follow the installer's design. You can send the design to our sales team to review
• Use as a base to lift equipment off the ground
• Need blocks with cast-in J-Bolts or a special size? They can be made to order, or send us your drawing
• For solar panels laid in long rows, a long solar mounting base lets the frame legs fix onto one continuous base instead of individual blocks (see the drawing on the product page)

Why precast blocks instead of casting on site

• No formwork and no waiting for concrete to cure: place them as soon as they arrive
• Every block has the same weight, which you can check
• Drawings of the 50×50×30 cm base and the long solar mounting base can be downloaded from the product page
