SubBase100 is a BRANZ appraised support for 100mm² & 90mm² piles and posts
SubBase100 enables one person to speedily set up 100mm² & 90mm² piles and posts in their footings prior to adding concrete.
They can be easily fixed to the piles and posts with screws or nails. They support the pile or post to allow the required 100mm of concrete underneath.
Made from bright plastic, SubBase100 are low cost, extremely strong, lightweight and stackable. Each SubBase100 can support over 400kg so piles and posts can be cut to length and bearers of fence rails fixed in place before the concrete is poured.
They're available in bags of 10 and cartons of 40.
Ask for them at your hardware store.
