Interlocking Concrete Blocks Neil Sullivan & Sons provide interlocking concrete blocks for fast, simple concrete construction. These large concrete blocks are ideal for constructing temporary buildings – such as storage bays – barricades, security/retaining walls, and more. The interlocking blocks are easy to work with and come in a wide range of standard sizes. If you need something more bespoke, we can also tailor blocks to your specific measurements. Blocks can be lifted and installed into place quickly using standard construction lifting equipment such as small cranes and forklifts. The interlocking mechanism of the blocks means each one fits together smoothly – and won’t become displaced accidentally. If you’re looking for prompt, safe and professional delivery of interlocking concrete blocks for your worksite, contact Neil Sullivan & Sons today. We operate throughout the Essex region and are happy to help with any enquiry.
