The subfloor is the layer that is located deeper, then just below the screed and that - usually - covers the electrical, water and, if present, mechanical ventilation systems. Lightened subfloors perform the function of:
Filling thickness/volume underneath the flooring;
Compensation layers for the installation of floor heating panels;
Creation of insulating layers;
Creation of slopes in the roof;
Direct installation of moisture-insensitive flooring on single-layer, fluid consistency lightened subfloor;
Lightening or insulating layers for any type of floor;
Waterproofing is a complementary work to make a material, indeed, waterproof, overlapping one or more layers of different materials to protect construction elements of various kinds such as floors, walls, tanks, wells, swimming pools.
There are several options for waterproofing materials and the choice varies according to: aesthetics, thickness and weight.
For the installation of a floor and wall covering with ceramic tiles or other stone materials, it is necessary to identify the most suitable tile adhesive on the basis of:
the characteristics of the substrate and the material to be laid;
the thickness to be created, also considering the intended use of the room.
The adhesive must form a sufficiently compact structure and have elastomeric and plastic characteristics that are consistent with the foreseeable movements and deformations of the supporting surface. They must also meet the requirements of international quality and safety guidelines.
As indicated in the term, these products are used to glue the insulation panels to the substrate and to smooth them, that is, to make the so-called "base plaster" layer.
The function of a glue for thermal insulation systems is to fix the support to bear the vertical load (i.e. the weight of the system) and the horizontal load (i.e. the thrust of the wind).
On the other hand, the layer of skim coat with interposed reinforcing mesh (reinforced skim coat) ensures protection to the insulating panel and mechanical resistance to the surface, to counteract the hygrothermal and surface tensions.
The wide range of adhesives and skim coats includes gray, white, fibrous, lightened, thick products, ETA certified and compatible with all types of insulating panels in use in the market.
The coating is composed of PREPARATION BASE and THICKNESS PLASTER and provides protection from atmospheric agents as well as greater mechanical strength, and determines the final result of the aesthetic component of the wall. All Grigotherm coatings are ETA certified. Further information
The insulation panels guarantee the thermal performance of the entire system, and can be of many types.
White sintered expanded polystyrene EPS or with graphite additives, with stress-relieving cuts, with improved adherence, in mineral wool or calcium silicate, in wood fiber or cork, each Grigotherm panel has its own characteristics, specific thermal conductivity and different lag times depending on the material of which it is made, all of which can be used in ETICS systems and certified for the specific application according to current European standards.
The nets and accessories are essential for the installation of a system of insulation coat. The mechanical characteristics of the mesh determine the quality of the intervention. The accessories such as corner protectors, profiles and loading elements are used for the management of the laying details and for the correct application phases. Further information
The purpose of the mortar is to unite the elements of the construction guaranteeing the static nature of the building.
Knowing that the availability of a vast number of pre-mixed mortars contributes to the good quality of the application and its duration in time, the line of Grigolin Lime Kilns allows to choose among many mortars suitable for the most different types, be they cement, exposed face, colored or high performance.
Lime is certainly one of the most versatile chemical products.
Lime is mainly used in all production processes where a basic agent (alkali) or a chemical component with a high degree of compatibility with other elements of the periodic table is required. In general, it is widely used in the most diverse sectors, from the construction industry to agriculture and animal husbandry, in the iron and steel industry and in land reclamation, for soil stabilization.
The product range includes slaked lime, calcium oxide, hydrated lime and micro-lime. The latter is produced by selecting the raw material and subjecting it to a processing cycle that allows to obtain a high purity micronized calcium hydrate (lime flower) with a particle size of less than 20 microns.
The products of the Inerts Line of Fornaci Calce Grigolin are natural or obtained by crushing alluvial or quarry inerts, carefully washed and selected. Their use allows to prepare, eliminating any waste, concretes, substrates, mortars and plasters in general. The products of the Inerts Line are used in restoration works and in the construction of small artefacts that can be used to consolidate land and for street furniture. Further information
The pre-measured bisacco Malte del Piave line was developed by Fornaci Calce Grigolin to provide professionals in the sector with a range of ready-to-use, quality products.
Malte del Piave are packaged in special polyethylene bags with a double compartment, in which the binder is separated from the inert to allow easy handling on site, considerable cleaning of the work area and to maintain the product's characteristics constant.
Technological reliability and customer service, which constitute the know-how of Grigolin Evoluzioni Costruttive, have given life to this line of Plasters, composed of a wide range of products diversified according to the final use, be it internal or external, and in relation to the support on which they are to be applied.
The line of Plasters offers many variants, from plaster to cement plaster, strictly premixed from controlled and selected components, which allow to meet all the demands of the site ensuring a very high quality.
Intended for injections (even at high pressure), they can be used in all contexts where cement grout can be used.
From valved micro-piles to tie-rods, from self-drilling bars to Jet Grouting: the use of special mortars for injection is almost universal since they do not contain any significant inert material. They can also be used for the consolidation with valved tubes and Jet Grouting columns (instead of silicates).
Highly insulating bricks and blocks (e.g. Poroton) must be laid with special bedding mortars, specially made to allow you to obtain a wall with insulation characteristics that comply with current regulations. They are essential to avoid thermal bridges and obtain an efficient insulation system. Further information
