The key element to the Patented Silca System is the Grate. This is the 400x450x38mm structural component that screws direct to the timber deck frame and provides the solid flat surface on which to lay almost any kind of paving.
Silca Grates feature:
a) strengthening ribs and hex cells to spread and transfer load across the decking element and down onto the joist.
b) pre-formed countersunk holes designed to guide the screws into the joist at the correct position. (remember to not overtighten screws as this can damage the countersink)
c) a second row of fixing so grates can be uniformly trimmed to slot in between joists should more height clearance be required. (This requires extra timbers clashed to the side of the joist for the grate to sit on.)
d) free draining design for minimum moisture retention
e) micro flex to absorb any movement within the decking element and reduce risk of any tile or grout disturbance
f) UV stable
g) manufactured from 100% recycled materials. Green Building Product
Silca I-Lock Connectors are used where screwing options are limited or not suitable, e.g. close to membrane, on ground applications, or simply to provide even more strength.
The connectors lock each Grate together with the adjacent Grate on all 4 sides. 2 Connectors per side. Simply push down into the designated slots in each side of the Grate, then nock in tight with a hammer.
Used for over membrane or concrete slab applications. At 15mm thick, the rubber mounts can be placed either directly underneath the Grates or underneath a ripped timber joist to provide drainage between it and the membrane. Please see more info about Deck Chair System mounts here: http://www.deckchairsystems.
We recommend using Silca I-Lock Connectors when Grates are installed over any floating frame.
