How to Anchor Handrails & Bolts in Concrete with QUIKRETE®


Anchoring handrails in concrete. Setting
handrails, bolts or metal posts in existing concrete
requires the use of a special, highly fluid expansive cement material called QUIKRETE Anchoring Cement. Standard cement based products shrink as
they cure and will leave a void between the existing
concrete and the newly placed cement mix surrounding the post. Anchoring cement expands as it cures, locking the post into place. QUIKRETE anchoring cement is a
pourable, rapid setting expansive cement that sets in 10 to 30
minutes and because it is Portland cement-based, it is suitable for continuously wet
environments. A masonry core drill should be used to create a hole that is at least 1 inch larger than the
diameter of the railing or bolt. The hole should be from 2 inches to 4
inches deep. By increasing the embedded depth of the post,
the pullout strength will increase. To mix anchoring cement, add about five
parts cement to one part clean water. Always wear
safety glasses and waterproof gloves when working with anchoring cement or any other cement-based product. Use a
margin trowel to thoroughly mix the material to a fluid consistency similar
to Syrup. Making sure that the mix is uniform and
lump-free. If the mix is too wet, add additional
anchoring cement and mix thoroughly. If the mix is too dry, add small amounts
of water sparingly. QUIKRETE Anchoring Cement is a rapid-setting material, so mix only as much as can be used in
about 10 minutes. Prior to pouring the anchoring cement,
remove any loose debris and dampen the hole. Do not leave any standing water. Slowly
pour the anchoring cement into the hole, around the post, to a level slightly above the surface.
Anchoring cement will reach over 4,000 PSI compressive strength in 24 hours and can support heavyweight in just two
hours. For vertical applications, simply add less water and mix to a
heavy putty consistency.
