We normally install frameless glass fencing into a concrete or stone patio. This enables us to core drill into the surface and cement the posts into the ground. Sometimes it is desirable to install a fence into a lawn or landscape area. In this situation we need to construct a concrete beam. This is how we do it.
First of all we did a 12″ wide, 12″ deep trench.
Every 10′ we must did a hole down to below the frost love. Here in New England this is 42″ below the finished grade.
We then line the trench with 3″ of gravel to facilitate drainage.
Rebar is installed in the trench on either side, not down the middle.
The trench and homes are then filled with regular concrete (3000 psi) to wishing 2″ of the top.
When dry, a cap stone (Bluestone or similar) is then cemented to the top of the beam to bring it up to the finished grade.
We can now drill the holes for the fence posts and install the glass fence.
