A modular fluid retention system and method for exemplary uses collecting and temporarily retaining fluids, for example stormwater run-off. One example of the system includes a plurality of modular retaining units which are selectively connected together to form an interior chamber volume for collecting stormwater run-off directed into the chamber volume. A plurality of modular trays are engaged with portions of the respective retention units to prevent relative movement of the retention units and eliminate, or substantially reduce, the need for porous material to be installed in and around the retention units greatly increasing the excavation void space usable for water collection and retention. In an alternate application, only a plurality of modular trays are used as the vertical support and fluid retention volume structure for the fluid retention system.

A modular storm water retention system and method for exemplary uses collecting and temporarily retaining storm water run-off. The system includes a plurality of modular retaining units which are selectively connected together to form an interior chamber volume for collecting storm water run-off directed into the chamber volume. A plurality of modular trays are engaged with the top portions of the respective retention units to prevent relative movement of the retention units and eliminate, or substantially reduce, the need for porous material to be installed in and around the retention units greatly increasing the excavation void space usable for water collection and retention. The trays further support the backfill material and prevent passage of the backfill material into the void space below the trays.

A supporting element for cylindrical or column-shaped elements of modular elements for making raised and/or ventilated floors, includes a substantially plane base configured to be rested on the underlying floor, two or more lateral extensions arranged at sides of the plane base and coplanar with the plane base, coupling elements arranged on the portions of said lateral extensions that are far from the plane base. The supporting element includes a first series of projections arranged along a circle centered on the plane base, defining a seat in which a lower end of the cylindrical or column-shaped elements is inserted and housed, and wherein the projections of the first series are configured to adhere to the surface of the cylindrical or column-shaped element housed in the seat.

A system for constructing raised floors includes a plurality of bases to be laid on a laying surface, and a plurality of upper modular elements or modules to be laid on the bases. A service cavity is created between the modules and the bases for the passage of cables, cable ducts, raceways, and/or for ventilation purposes. Each module has an upper part and support feet, and each base has a raised part or cup-shaped element, the upper edge of which is configured to support a foot of one or more of the modules, the one or more modules and the cup-shaped element being mutually constrained. Each of the bases also includes one or more arms and/or connecting portions, removably or non-removably constrained to the cup-shaped element and configured to mutually constrain two or more bases.

The present disclosure describes a sound attenuating flooring system. The sound attenuating flooring system has a subfloor, a sound attenuating material overlaying and contacting only a portion of the subfloor, and an overlayment. The sound attenuating material has a first surface and second surface. The first surface is defined by a plurality of outwardly projecting hollow protrusions. The second surface is defined by a plurality of open recesses corresponding to the plurality of outwardly projecting hollow protrusions. The overlayment overlays the second surface of the sound attenuating material.

A composite structure for a floating floor system including at least one layer of force muting material and a layer of formwork, wherein the layer of formwork is located on the at least one layer of force muting material wherein the layer of formwork is a half closed folded honeycomb structure or a relaxed honeycomb structure.

A floor construction on a subsurface has a screed with a reinforcement made of a 3D textile with a lower and an upper textile ply which are connected together by one or more pile threads, wherein the lower textile ply is arranged in the lower half of the screed and the upper textile ply is arranged in the upper half of the screed, wherein an insulation layer is preferably furthermore arranged between the subsurface and the screed. The reinforced screed of the floor construction allows thin screed layers with good load-bearing capacity. Good footfall sound insulation can be achieved with the floor construction containing an insulation layer.
