Our SilcaSpacers ™ are one of our more recently developed products. These spacers are designed to perfectly fit with various stone, porcelain and pavers of all types and our SilcaGrate™. The rigid SilcaSpacers ™ ensure a good polymeric sand joint with even spacing, and when installed with adhesive help to prevent rocking of pavers. You can use the SilcaSpacers™ along with the other products in our Silca System ® line to create a reliable and durable sub-flooring system that works in harmony to support the deck of your dreams. The SilcaSpacers ™ come in three different variations; flexible, black rigid and clear rigid.
