Standard for enlarging foundations and first step in adding shotcrete to brick walls.

Using screen tubes is a common way of controlling epoxy from sagging. A better way is to use thicker epoxy paste.

Prepare holes with 150+ p.s.i. air blast.

Hole Size Chart for Epoxy Dowels:
#3 -- 5/8" hole   #8 -- 1-1/4" hole
#4 -- 5/8" hole   #9 -- 1-3/8" hole
#5 -- 3/4" hole   #10 -- 1-1/2" hole
#6 -- 1" hole   #11 -- 1-5/8" hole
#7 -- 1-1/8" hole   #12 -- 1-3/4" hole

For deep holes, increase hole diameter. Cement-grouted dowels require much larger holes usually found only in CalTrans specs. We use DAYTON J-58, KEMKO, Covertsystems, Sika, and other epoxy paste and automatic mixing pump.
