ICF

This system is identical for reinforcing layer and subsequent application of brick slips on to externally fixed insulation board and onto an ICF construction.

Technical Information for Component Parts

(Technical Approval Certificate available)

Ceresit CT85-25kg	Reinforcing mortar	Coverage 4kg/m²
Ceresit CT 325	Glass fibre reinforcing webbing	50m Roll
Fischer	Fixing anchors	Length dependant on depth of insulation.
Ceresit CM18-18kg	Adhesive	1.2kg/m² with 4 mm tooth depth
Ceresit CE 35	Pointing/grouting mortar	Coverage dependant on size and depth of joint.

After the external insulation layer has been checked to ensure flatness, the reinforcing mortar is applied and while it is still wet the mesh is laid into it. Each length of mesh must overlap the next one by 100mm and wrap all corners and into the window embrasures (a butt joint is a potential source of future cracking).

The correct size fixing anchors are put in place, (depth of insulation plus 35mm into concrete core), working while the mortar is still wet. The head is then covered by a small patch of mesh and mortared in place. They are placed at the rate of 5 per m².

The adhesive is a cement based flexible adhesive with a high bond strength. This type of adhesive is the most straightforward to use, having a good initial grab, reducing or eliminating the need for support. Working characteristics are similar to normal mortar.
