Ballast-Lok® Slab

Ballast-Lok® Slab

Brooklin’s Ballast-Lok concrete roof slabs and locking clips provide superior wind uplift resistance for protected membrane roofing systems. The innovative Ballast-Lok system has been proven to withstand wind uplift pressure of 180psf (8.6kPa), using the experimental safety factor of 1.5 as per the CSA A 123.21-10 dynamic wind test protocol.

As weather patterns become increasingly erratic, protecting flat roof decks from wind uplift is a growing concern. Over time, wind dynamics can cause fatigue in rooftop materials and lead to disastrous failures. The Ballast-Lok system provides insurance by locking down concrete roof slabs with high-performance polyethylene clips and pedestals.
