CONCRETE FLOORS - Maintenance and repair

BECAUSE IT IS IMPORTANT

A floor in perfect state of conservation optimizes workflow, preserves vehicles and operator’s health, with significant cost savings.

Prima is structured to offer a highly qualified maintenance service (even programmed) and industrial floor repair, bringing them to fine conditions both in terms of functional appearance and durability.

Deterioration’s reasons of your floors can be multiple:

surface wear, with resulting dust dispersion, holes, cracks and breaks formation.
loss of flatness due to wear
contact with chemicals
incorrect design
breaking of construction and contraction joints
cracking and widening of cracks
scrapping the surface due to frost in outer floors
deformation of concrete slabs, also caused by subsidence of substrate
degraded caused by handling means with hard wheels

Our highly specialized internal teams install certified systems, based on high performing innovative materials, with very low VOC emissions. We use the latest equipment generation, designed to avoid equipment, dispersing, guaranteeing punctual, and very rapid execution times. We limit interference with the production flow of the client’s business.

RESTORING CRACKS, JOINTS AND DEGRADED AREAS

We evaluate cracks present on flooring (position, width and depth, artifact years of life) to identify the most suitable solution for their restoration, and the interruption of the cracking phenomenon.

Prima also restores damaged joints: after a preliminary inspection, we offer to customer the possible solutions suitable to do reconstruction with resinous or cement mortars, or we install the Smart Joint®, our definitive and exclusive solution to restore in only 12 hours damaged joints, canceling future maintenance needs.

With this kind of intervention, we grant the joint resistance to stresses caused by heavy and intense traffic. With proper joint maintenance, you’ll have cost savings also on handling vehicles maintenance (wheels, tabs, mechanical parts) which will no longer be subject to glitches and vibrations and will comply with warranty plans. Last but not least the importance of health benefits for operators and the prevention of occupational illness.

Prima also deals with localized restoration of holes and degraded areas by rapid drying and high resistance epoxy formulated.

Industrial flooring frequent problems

Prima identified and apply specific certified systems, aimed at resolving all the major and recurring problems affecting industrial concrete flooring, such as:

Floors with high residual humidity

One of the frequent reasons that cause a rapid degradation of the flooring is related to the composition of the mix of concrete used, as this contains an excessive amount of water in the mix. We ensure a correct dosage of the water and the mix design of the concrete, with the use of binders and additives, avoids this type of problem and performs specific tests on the materials supplied on site.

Another cause is the presence of rising damp. On the screed there are humidity spots coming from the underlying substrate as it is free of a vapor barrier. We always install a vapor barrier (polyethylene sheet) of suitable thickness, which prevents the rise of humidity from the underlying layers.

Cracked floors

The screed has some or many cracks on the surface. Possible causes are due to wrong concrete mix-design used for the substrate, where there is an excessive amount of cement in the mix, aggregates rich in fine parts, or too much water present in the mix.

Over time, these defects are the cause of a posteriori problems such as the formation of cracks in the finishing coating, with consequent uncontrolled shrinkage of the substrate or infiltrations that damage its structure.

Floors with structural failures

Possible causes are related to the incorrect construction of an underlying ballast or its poor compaction or the use of an inadequate quality and strength concrete. We always avoid these facts by careful planning and carrying out compliance works. In these situations we have structural restoration systems.

Degraded surface flooring

Premature surface wear is often due to a lack of surface hardener (dusting), consequently, the surface becomes crumbly, dusty and absorbent. In these cases, to solve the problem, we suggest to proceed with consolidation actions and the subsequent realization of a new surface layer.
