6 Types of Sealant Repairs in Concrete Concrete
2
Control joint sealant?

• Control joints, designed to control where cracks
  appear in concrete placed horizontally or
  vertically, are themselves are sealed against
  water, frost, debris and to handle recurrent
  movement (listed below) using a flexible sealant.

3
Recurrent movement

• Seal and repair cracks in concrete using
  injection of either epoxy resin or polyurethane
  where recurrent movement is expected (in my
  opinion a flexible sealant is what's called for
  here) when the movement is considered normal,
  perhaps caused by traffic vibration or
  temperature swings, and where the movement is not
  threatening structural damage.

4
Stop a water leak

• Seal and repair cracks in concrete when it is
  important to quickly stop water leaking through a
  crack,seal those cracks in concrete using
  injection of either epoxy resin or polyurethane
  sealant.

5
Structural repair

• Seal and repair structural cracks for some
  situations (usually where an engineer, expert in
  masonry repair has made an assessment), actual
  structural repairs are made using injectable
  epoxy resin and possibly in some (probably
  low-load) cases by using injectable polyurethane
  sealant.

6
Structural Reinforcement?

some sealant manufacturers such as Sika provide
seal or wrap-and-seal systems that actually
provide additional strength to existing concrete
structures such as concrete columns. Structural
reinforcing wrap systems may include use of
synethetic fabrics, carbon fibre fabrics, and
other wraps. These products might also be used on
steel or concrete that has been damaged by
weather, frost, corrosion.

Surface repair

• For working surfaces such as industrial work
  floors or parking decks cracked by spider-webbed
  shrinkage cracks that are non-structural, special
  "healer-sealer" crack sealants may be applied
