Repairs – Concrete Reinforcement

A FEW WORDS ABOUT CONCRETE REPAIRS AND REINFORCEMENTS

The vast majority of buildings in our country were constructed at a time when energy efficiency standards were not applied.

the current strict anti-seismic criteria in the construction of projects
The vast majority of today’s buildings have many problems due to their age.

which make them dangerous in cases of strong seismic activity with characteristic

example: the 1999 earthquake in Attica
The field of repairing and reinforcing existing structures requires specialized expertise and

requires special attention in choosing the type of interventions
We provide solutions for all pre-earthquake and anti-seismic inspection issues.
We undertake individually the study of reinforcement-repair of each structure or construction.

respectively
Repair, reinforcement, and restoration of load-bearing structures in buildings and general constructions made of

Cementing
Reinforcement of load-bearing walls and foundations
Filling the gaps in the masonry with grout enriched with the appropriate admixtures.
Epoxy resins
Restoration of cross sections by filling under pressure (injections), surface coatings, anchoring.
Demolition of floors
Sandblasting and/or hydroblasting.
Preparation and mechanical roughening of surfaces for coating application.

Gunite shotcrete

It is a mixture of cement and aggregates (sand) that is prepared and sprayed.
mechanically by adding water
The material that is applied to the surface is called a coating. If it has been reinforced with reinforcement
It is called armed cloak.
Caps on reinforced concrete elements, caps on masonry, stiffening walls, slopes, fire protection.

Why it is used:

High compressive strength due to low coefficient
Very good grip
Self-supporting and can be used at the bottom of horizontal elements with a thickness of
up to 50 mm for each layer.
Shotcrete is applied with excellent results on concrete surfaces,
in masonry, in rock, even and in steel
Earthquake-resistant reinforcement of buildings
Rice paddies-anchors
Securing and maintaining the facades of listed buildings
Repair of damage to structural elements
