The Prevention of Insulation Construction

                      External wall insulation construction problems and their prevention

•  Usually the external wall insulation construction problems as following :

1.) Cracks and damage :

        wall crack

   Cracking, damage

• Causes of cracks of external wall insulation construction:

1) Plastering mortar has high elastic modulus and insufficient crack resistance

   Low gel content; high cement content;

  "Crown ratio" does not reflect good flexibility, pay attention to impact resistance;

  Grid extra wall insulation mortar is too thick.

  Wall insulation mortar exceeds operating time.

2 ) Glass fiber grid reinforcement effect difference

 Poor alkali resistance;

Low breaking strength, low grammage, no double-layered network in the first floor;

When laid, it is not flattened;

The lap width is not enough or even not overlapped;

3 ) Not properly used, lack of normal maintenance

Exceeding the permission of heavy objects and hard objects crash against the wall;

Eliminating holes to install building outline lights;

Failure to repair in time makes the problem worse;

(width 0.2mm is the limit)

Some projects have considered tile finishes, fences, and green belts at the time of design to prevent improper man-made activities from damaging the walls.

•  Leakage 

Line pipe outlet handling badly 

steel-rebar mouth processing badly 

Leakage causes of external wall insulation mortar :

1.)The design is rough, without considering how the wall attachments are handled; no suitable fittings are selected;

2) Construction is irresponsible and there must be no openings or leaks that can seep through.

 3) Supervision should strictly check and check;

  4) Owners should keep in mind that there is no good for the cheap.
