Cracks in the new building

Project Overview

The building is a newly built building with a height of three floors. The floor cracking phenomenon is occurring during the construction of the roof layer.

Analysis by professional technicians

(1) Due to the temperature difference effect of the sky surface concrete slab, the structural cracks in the irregular distribution of the roof structure are caused.

(2) The surface waterproof treatment of the original building is imperfect,

Suggestion:

(1) To repair the site of structural hidden danger (crack).

(2) Carbon fiber strengthening concrete slab to meet the requirements of the building function.

Strengthening materials

HM-30 carbon fiber fabric

HM-120ML crack repair adhesive

HM-120L crack injection adhesive
