We guarantee all our work with a warranty.

If you choose interlocking we have options to give you a extended guarantee. By combining interlocking with Ultra-base you extend your 1 year warranty to a 2 year warranty. Ultra-base is a very coarse concrete mix which is placed beneath any surface which requires a stronger, heavy duty base. (ie parking a heavy car or truck). It is a permeable layer of concrete (4″-6″ that o?ers the support and strength of concrete but allows us to place the more weather resistant, non-slip surface of interlocking over top. This type of foundation is very cost e?ective for high tra?c areas and comes with a 2 years warranty. This option is only available for interlocking pavers.

Ask about our Polymeric jointing sand upgrade for interlocking.

Polymeric sand is a granular material placed between the joints or seams in brick pavers or stone in patios, walkways and driveways. It’s primary function is to improve the interlock and therefore the durability and stability of a paved surface. Until 4-5 years ago, this function was performed most often with silica or torpedo sand. The sand would be swept between the joints of a brick paver, bluestone or flagstone patio, and it’s mere presence would enhance the interlock between pavers or stones. (“Interlock” is another way of expressing a segmental pavement’s ability to resist movement via friction between pieces of pavement.) Often that sand would be stabilized by applying a sealer to the pavement; the sealer would help to maintain certain characteristics of the pavers or stone, and would harden the uppermost layer of joint sand, making it resistant to water washouts, ants and weeds.
