5 Most Common Epoxy Anchoring Mistakes
#1 Incorrect Drill Depth and Size
Every anchor has a required depth and size for the threaded rod anchor that provides the required load strength within the concrete
foundation. It’s common for installers to drill too short and not accurately measure the
depth of the hole. Taking the time to measure and accurately drill the hole is the first step in
guaranteeing the anchor will maintain its required value.
#2 Not Properly Cleaned
Concrete dust and small trash can easily block the full embedment depth of the threaded rod anchor. Debris and dust can easily mix
with the epoxy lessening the composition and curing strength of the epoxy. It is important to make sure each hole is brushed and cleaned using compressed air, a hand pump, or dust
blower before installing the anchor. Failing to do so puts the project at risk.
#3 Standing Water in the Hole
It’s common to see standing water on job-sites. Whether it’s caused by natural rain or
from clean-up crews it can easily fill or partially fill a drilled hole. It is required that
the concrete hole is dry before epoxy installation. All water has to be removed
from the hole using a vacuum and/or compressed air prior to cleaning.
#4 Temperature Too Cold
External temperatures can have negative effects on the proper mixing and curing of epoxy. When
installers leave epoxy exposed to external temperature the epoxy can be too cold to properly install. The cartridge temperature has a minimum temperate range for installation. It’s important to
keep the epoxy inside to maintain the required temperature range. To solve this issue, installers will keep epoxy stored inside a job site trailer or
under controlled temperature.
#5 Incorrect Curing Times
Adhesive curing times can vary between 4 and 48 hours, so it’s important to not disturb,
torque, or load the anchor until it is fully cured. It’s common for installers to assume
epoxy curing times. That’s why it’s important to check epoxy curing time tables as per
manufactures recommendations to accurately plan and prepare project timelines
to accommodate curing times.
