Definitions

  • the disclosed technology includes paver adhesives, such as dry concrete mixes, as well as methods for laying paver tiles using such paver adhesives.
  • Each disclosed paver adhesive is configured to be distributed on a substrate (e.g., a sidewalk, concrete pad, driveway, stone, or other solid surface) while the paver adhesive is in a dry state, such that bricks, paver bricks, pavers, or paver tiles (referred to generally herein as “pavers” or “paver tiles”) can be laid atop the paver adhesive while the paver adhesive is still in the dry state, and the paver adhesive can be hydrated after the pavers have been laid.
  • the disclosed paver adhesives can provide a strong and durable adhesion between the pavers and the substrate, and the paver adhesives can withstand vehicular traffic without significant cracking, releasing or otherwise degrading.
  • the base material typically a limestone gravel
  • the base material is then typically covered with a layer of sand, which is compacted and leveled as a layer to support the pavers.
  • the pavers can then be laid on top of the leveled sand layer.
  • at least some of the pavers must be secured. It is commonplace to secure at least the pavers at the edges of area being paved, such as by a concrete edge, pavers set in concrete, or a metal or plastic fixed edge.
  • the pavers that are secured are thicker and more expensive than typical pavers. Accordingly, the process to convert a concrete (or any other material) driveway, sidewalk, or other area to one paved with pavers can be expensive, disruptive to existing landscaping, and time consuming.
  • pavers are generally seen as an approved or acceptable product for remodeling pool decks, backyard patios, walkways and courtyards.
  • pavers are not typically for vehicular applications, such as installation as an overlay on a driveway or other vehicular application.
  • any pavers installed atop a driver would crack and break apart from the weight of the vehicle, as well as the various forces experienced by the pavers, such as those provided by any twisting and turning of the tires.
  • any adhesion of the pavers to the underlying substrate typically requires the adhesive — typically, a concrete mix — to be pre-mixed.
  • the adhesive typically, a concrete mix —
  • the pre-mixed concrete mix or other adhesive is hydrated prior to application on the ground or substrate.
  • the hydrated mix must be permitted to cure, which will ultimately fixedly attach the pavers to the underlying surface.
  • this process can be messy, difficult, and cumbersome.
  • the installer is afforded only a certain amount of the time to install the pavers atop the adhesive before the adhesive cures and hardens. This time-based issue can become a burden in and of itself and can cause the installer to hurry the installation, which can lead to shoddy or inferior installation.
  • the disclosed technology includes a dry concrete mix for dry setting paver tiles, and the dry concrete mix can include cement , silica sand, alumina silicate, and a latex polymer and/or acrylic polymer.
  • the cement can be in a concentration range from approximately 23 wt.% to approximately 70 wt.%.
  • the cement can be in a concentration range from approximately 23 wt.% to approximately 70 wt.%.
  • the cement can be in a concentration range from approximately 25 wt.% to approximately 60 wt.%.
  • the cement can be in a concentration range from approximately 20 wt.% to approximately 40 wt.%.
  • the cement can be in a concentration range from approximately 21 wt.% to approximately 30 wt.%.
  • the cement can be in a concentration range from 23 wt.% to approximately 40 wt.%.
  • the silica sand can be in a concentration range from approximately 30 wt.% to approximately 79 wt.%.
  • the silica sand can be in a concentration range from approximately 30 wt.% to approximately 78 wt.%.
  • the silica sand can be in a concentration range from approximately 30 wt.% to approximately 74 wt.%.
  • the silica sand can be in a concentration range from approximately 30 wt.% to approximately 70 wt.%.
  • the alumina silicate can be in a concentration range from approximately 0.5 wt.% to approximately 6 wt.%.
  • the latex polymer and/or acrylic polymer can be in a concentration range from approximately 0.5 wt.% to approximately 8 wt.%.
  • the latex polymer and/or acrylic polymer can be in a concentration range from approximately 0.5 wt.% to approximately 5 wt.%.
  • the latex polymer and/or acrylic polymer can be in a concentration range from approximately 23 wt.% to approximately 70 wt.%;
  • the disclosed technology also includes methods for laying paver tiles using the disclosed paver adhesive or concrete mixes.
  • FIG. 1 shows a paver tile used in an embodiment of the method, wherein the paver tile comprises a bottom surface defining grooves.
  • references to “one embodiment,” “an embodiment,” “example embodiment,” “some embodiments,” “certain embodiments,” “various embodiments,” etc., indicate that the embodiment s) of the disclosed technology so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment” does not necessarily refer to the same embodiment, although it may. [0020] Throughout the specification and the claims, the following terms take at least the meanings explicitly associated herein, unless the context clearly dictates otherwise. The term “or” is intended to mean an inclusive “or.” Further, the terms “a,” “an,” and “the” are intended to mean one or more unless specified otherwise or clear from the context to be directed to a singular form.
  • the disclosed technology includes a paver adhesive or dry concrete mix that includes Portland cement, silica sand, alumina silicate, and a latex polymer and/or an acrylic polymer.
  • the disclosed paver adhesives can be used in methods for installing paver tiles on a substrate, such as a concrete pad, an asphalt pad, the ground, or some other substrate.
  • the method can include distributing the paver adhesive in a dry form over an area to covered with paver tiles (e.g., a substrate), positioning the paver tiles over the paver adhesive, and hydrating the paver adhesive subsequent to positioning the paver tiles. Once hydrated, the paver adhesive can be permitted to cure and harden.
  • dry as used with respect to a dry paver adhesive or a dry concrete mix refers to the paver adhesive or concrete mix lacking added water. That is, while the dry paver mix or dry concrete mix may contain some moisture (e.g., depending on the ambient humidity), the paver mix or dry concrete is still considered “dry” so long as water or hydrating fluids have not been added to the mix.
  • the disclosed technology includes paver adhesives or concrete mixes that are dry (packaged), no-mix, polymer-modified, cement-based mortars.
  • the paver adhesives can be configured to be distributed or applied in a dry state and hydrated in situ subsequent to laying paver tiles over the dry concrete mix. That is, the disclosed paver adhesives are formulated such that paver tiles can be laid over the paver adhesive while the paver adhesive is in a dry form, and the paver adhesive can then be hydrated after some or all of the pave tiles are laid. This is in contrast to conventional approaches that require shear mixing of mortar with water before placement of paver tiles.
  • the dry concrete mix comprises cement (e.g., Portland cement), silica sand, alumina silicate (e.g., perlite), and/or latex polymer and/or acrylic polymer.
  • the dry concrete mix can include calcium carbonate.
  • the Portland cement can include Type I cement in a concentration range between approximately 40 wt. % and approximately 60 wt. % and Type III cement in a concentration range between approximately 40 wt. % and approximately 60 wt. %.
  • alumina silicate, perlite, or another material for water retention can promote water- retention in the eventually hydrated paver adhesive or concrete mix, which can aid in curing.
  • the latex and/or acrylic polymers can also promote water-retention and adhesion between the paver tiles and the underlying substrate.
  • the latex polymer and/or acrylic polymer can be a powder, such as a dry, redispersible powder.
  • the latex polymer and/or acrylic polymer can include, but is not limited to, poly(ethylene-vinyl acetate), poly(vinyl acetate-ethylene) (VAE, VAc/E), poly(vinyl acetate/vinyl ester of versatic acid) (VAE/VeoVa, VAM/VeoVa), poly(styrene acrylate), poly(ethylene-vinyl acetate), acrylic homopolymer, acrylic copolymers, acrylic terpolymers, poly(acrylic esters), polyvinylidene chloride (PVAC), poly(styrene-butadiene), polystyrene- butadiene) copolymers, poly (styrene-butadiene) terpolymers, or any useful combination thereof.
  • Qualities of the formulations can be influenced as desired by the concentration of certain materials. For example, increased concentrations of latex and/or acrylic polymers can improve adherence and ultimate performance of the paver adhesive, but this may also increase the cure time of the paver adhesive. Thus, it may be beneficial to increase the concentration of a component (e.g., alumina silicate) to regulate water evaporation and offset the increased cure time.

  • the layer of the applied paver adhesive can have a depth in the range between approximately 0.25 inch to approximately 0.5 inch.
  • additional paver adhesive e.g., a thicker layer
  • additional paver adhesive e.g., a thicker layer
  • the method can include covering any existing expansion joints or cracks of the substrate with the paver adhesive.
  • Small cracks e.g., up to 0.75 inch
  • the substrate is damaged to a greater extent than small cracks, it may be necessary to cut out the corresponding portion of the substrate to the full depth of the substrate and repair the corresponding portion of the substrate prior to continuing the disclosed method.
  • repairing a portion of the substrate can include refilling the removed portion of the substrate with concrete or the like using rebar, which can help provide adequate strength for the substrate.
  • the method can include laying (e.g., setting, positioning) paver tiles over or atop the dry paver adhesive. It may be helpful to lay paver tiles to track any outer edges of the substrate and/or to abut any structures adjacent to the substrate (e.g., a house, a building, a retaining wall). That is, it may be helpful to create a border of paver tiles.
  • the method can include cutting a groove in the substrate at or near the border. The groove can provide a channel for increased paver adhesive depth, which can help enhance bond strength between the border tiles and the substrate. Similarly, it may be beneficial to cut two substantially parallel grooves at or near the border of the substrate.
  • the method can include mixing a latex modifier and/or hydrating the paver adhesive to create a wet mortar and spreading the wet mortar along the border area of the substrate.
  • the corresponding border tiles can then be laid atop the wet mortar bed and permitted to cure and/or harden. This can enable a user to create a solidified border without wetting the interior area where the dry paver adhesive is located or will be applied.
  • the method can include hydrating the dry paver adhesive, which can include spraying or otherwise applying water atop the installed paver tiles and the underlying paver adhesive. Once the paver adhesive has been sufficiently hydrated, the method can include spreading or distributing mason sand over the installed paver tiles to fill joints. Once hydrated, the method can include permitting the paver adhesive to cure and/or harden and to gain strength before beginning normal use. For example, it may be necessary to wait approximately 24 hours to approximately 72 hours before beginning normal use.
  • the disclosed technology can enable secure adhesion of paver tiles to a substrate.
  • the layer of paver tiles above the hydrated paver adhesive can serve as a curing membrane to prevent rapid evaporation of the water in the hydrated paver mix.
  • any border construction made by laying down a wet mortar bed and a layer of paver tiles can serve to contain the hydrating water subsequently applied to the interior portion of paver tiles laid atop the dry paver adhesive and thus preventing hydraulic pressure from “washing out” the dry paver adhesive from beneath the interior paver tiles.
