Why the damp

The damp and the moisture in the masonries constitutes a chain of problems, inconveniences and damages in the housing for repairs and maintenance. The conditions and morphology of the structures and autochthonous elements (kind of the ground, water table and rainfall) represent the variables on the whole. For this reason, it’s essential to check up all those variables in order to recognize the most suitable solution. As said, dampness and infiltrations in buildings for storage or in underground structures, are the key reasons of decay. Hidra offers consistent and suitable solutions, suggesting a curing and waterproofing system at a low thickness: Hegea. In those areas, dominated by very expensive and invasive solutions, the utilize of the curing and waterproofing Hegea cycles, combine the usefulness of the treatments to the readiness of the non invasive intervention. The possibility and convenience to act where the surfaces are already improving and other situations most unrecoverable, enable exceptionally efficient and adaptable in the waterproofing and curing areas the Hegea range of products.

Where

Application areas

Depending from the kind of setting, it’s necessari to employ differentiated Hegea treatments.

Damp ascending

Curing by dehumidification of the masonries that, cause to the absorption of water from the ground, show damp ascending, decay, erosion on the surface and mold.

Waterproofing for storage buildings

Positive waterproofing for buildings like basins, swimming pools, flower boxes and containers for water or soil, presenting localized or widespread infiltrations, cause cracks, slits or non proper materials.

Counter ground waterproofing

Negative waterproofing in counter ground buildings like chutes or dike walls, and in underground structures like basement or cellars, showing localized or expanded water damages from the back. Negative waterproofing: counter ground infiltration, subjected to pressure from the back.

How

Predisposition of the surface

The peculiarity of the Hegea cycles, is the handiness of their application: plasterworks, aged surfaces, rows, well cohesive and with roughened reinforced concrete, all these surfaces can be well apt. Hegea range of products, thanks to its assortment of thicknesses allows to act in any kind of area having a good cohesion and steadiness of the underlying structures. The preparation of the supports deal with four points:

1 - SCRATCH

it’s necessary to act on the row surface, so it’s essential to remove painting, plastering and levelling through mechanical scratch or sandblast. On the reinforced concrete, it’s requested to roughen it by mechanical device the areas too smooth.

2 - STRENGHTENING

remove the damp and efflorescence from the incoherent surfaces and too weak areas till reach the surface fit for the action.

3 - RESTORE

restore areas which have not a good cohesion level, using mortars with concrete or fibre. Wait for the complete seasoning.

4 - MOISTURIZING
