Frequently Asked Questions

How do the pavers interlock?

All of CastleLiteʼs concrete pavers are interlocking. Regardless of which shape, color or laying pattern you choose, they are ALL interlocking concrete pavers. The term “interlock” is used to describe the internal friction imposed by the joint sand between the concrete pavers. It is this interlocking feature that give concrete pavers the flexibility and durability to withstand minor and major movements of the native soils. Maintenance and repairs (if required) are simplified because no mortar is used in the installation process.

What type of sand should I use between my concrete pavers?

We recommend an angular washed sand with sand grains between a No. 10 and No. 30 sieve. The use of angular sand will bind together during the compaction process. The problem with using a very fine sand is it will wash out easily and will cause an interlock failure.

If you have any specific questions, feel free to contact one of our knowledgeable sales representatives.
