System for paver support and method for installation of same
View Patent ↗A system for supporting a paver layer that includes a layer of sand, a concrete layer, a base, drain pipes, and a gravel layer. The layer of sand, the concrete layer and the concrete layer are each formed in a substantially horizontal direction, with the layer of sand being formed above the concrete layer and the concrete layer being formed above the base. The drain pipes are provided in a substantially vertical orientation, with an upper end of each drain pipe provided within or slightly below the concrete layer.
1. A system comprising:
a sand layer;
a concrete layer;
a base;
a gravel layer;
a drain pipe; and
a permeable sand block,
wherein the sand layer is formed above the concrete layer, and the sand layer and the concrete layer are each formed in a substantially horizontal direction,
wherein the drain pipe is provided in a substantially vertical orientation with an upper end of the drain pipe provided below an upper edge of the concrete layer,
wherein the permeable sand block is secured by a tie to an outer circumference adjacent to an upper opening of the drain pipe, and
wherein the tie is secured in a groove in the drain pipe that is adjacent to the upper opening of the drain pipe.
2. The system of claim 1 , wherein a bottom end of the drain pipe terminates in the gravel layer provided in the base.
3. The system of claim 1 , wherein the system is configured to support a horizontal layer of paver blocks.
4. The system of claim 1 , wherein the base is formed of unexcavated earth, other than excavation of a drain hole configured to accommodate the drain pipe.
5. The system of claim 1 , wherein the drain pipe includes a hollow extending from the upper end to a lower end opposite the upper end, and
wherein the hollow is configured to be filled with permeable rock.
6. The system of claim 1 , further comprising two additional drain pipes spaced apart from the drain pipe by a predetermined distance,
wherein a web is formed by spacing the two additional drain pipes apart from the drain pipe by the predetermined distance.
7. The system of claim 1 , wherein the concrete layer includes a concave portion positioned above the drain pipe.
8. The system of claim 7 , wherein the concave portion has an opening at a bottom thereof of a size corresponding to a size of an upper opening of the drain pipe.
9. The system of claim 1 , wherein the permeable sand block is landscape fabric.
10. The system of claim 1 , wherein the permeable sand block is configured to preclude passage of sand from the sand layer and to allow flow of water therethrough.
