Grodan Expert Slab


 Up to 10% drier than our previous Neptune slabs


 Pargro Quick Drain

Pargro QD slabs are up to 10% drier than our previous Neptune slabs. Jumbo is a particularly good choice when you want to use a big block in an ebb and flow system. If you want a drier top, then opt for the Biggie in your system, since capillary movement will generally not reach above 4” in a block on most flood tables
