Under the three circumstances, it is necessary to reinforce the slab: 

1. the bearing capacity of the slab is insufficient;

2. the strength of the floor slab is unqualified;

3. the slab is opening.

   
   

The method of slab strengthening

Bonded carbon fiber reinfroced polymer(CFRP)

1.Load Increase

2.Seismic strengthening

3.Damage to structural parts

4.Change in structural system

5.Design or construction defects

 






Epoxy bonded steel plate

1.All kinds of building structure reinforcement, wall floor, beam-columns and other steel-bonded reinforcement;

2.Various types of anchorage of water conservancy facilities, piers, highways, bridges and other projects;

3.The steel planting and anchor bolt anchoring of various building projects.

4.Epoxy bonded steel plate

Enlargement section(strengthening materials: anchoring adhesive)

1. Fix steel bar and bolt in concrete.

2. Fix bracket of curtain wall stone hanging.

3. Strengthen construction structure and bar anchoring.

4. Fix various equipment base.

5. Anchorage connection between steel structure and concrete structure.

6. For Reconstruction and extension project reinforcement of railway, highway, bridge and water conservancy project.

7. Fix billboards, tunnel line, sound insulation board of elevated road and barrier

8.Reinforced concrete jacketing(RCC jacketing):clomn jacketing,beam jacketing

9.Section enlargement

10.Seismic retrofittng

Crack repair

1.High speed, high efficiency, short terms.

2.Excellent performance: very strong penetration. 

The strong permeability can penetrate the cracks quickly, control the development of the cracks and enhance the strength of the components.

3.Rearing cracks at the same time. 

The injection of a crack is automatically injected at the same time. Because the inner hose and sleeve are all transparent, the operation is clear at a glance. The grouting effect can be completely confirmed at the scene, and the quality is reliable. 

4.The injection device is very light and convenient in construction, no need for electricity. 

It can be used in harsh environments such as horizontal direction and vertical direction, high altitude, barrier, field and no power supply. It has strong adaptability and no noise, convenient and safe.

5.The crack resin and its supporting materials have good performance, easy to use, nontoxic, non irritating odor, on-site civilization, and safe.
